They replaced a very good Klipsch 2
346594
I've had these for 4 months now. They replaced a very good Klipsch 2.1 ProMedia system. These, paired with an 8 inch Dayton sub blow the Klipsch system away. If you are looking to step up from a prepackaged computer speaker system then look no further. I found them to be a bit lacking in bass themselves, hence the additional sub. Clarity is phenomenal. I can hear so many more details even when listening to lossy sound sources like Spotify. I do recommend FLAC files for PC use but everything will sound better.
Last night I sat down at my computer and listened to some music, turned to my wife and said, my speakers sound amazing. I'm still amazed by how good they are after 4 months. I thought they would sound normal to me now I am used to them but instead they continue to surprise me.

This is my second one of these. The first one I bought several years ago, and it failed despite being used only a couple of times per year.
The sound quality of this crossover is excellent. It is better than some high-end brand crossovers I've owned that cost several times what this one did. I have a critical ear, and a lot of very high-end PA equipment. It was important that my crossover not degrade the sound of a lot of elite, expensive amps, speakers, and mixing console. And, I needed three-way stereo capability with continuously variable crossover frequencies, preferably in 1 rack unit. This fits the bill extremely well and has a lot of great extras- the multiband limiter, independent phase invert switches and mute switches for each band, adjustable LF delay, and a switch to optionally sum the LF outputs to mono.
However, my first one didn't last as long as a piece of this nature should, IMO. I started having problems with certain outputs (LF, Mid, High Lefts and Rights) intermittently cutting out. Cranking the input levels to the Xover would cause them to suddenly pop back in. The symptoms were almost exactly like that of bad output protection relays in a power amp, but there are no relays here. Additionally, the right channel HF output would have a big dip in the frequency response of mid-highs (well above the crossover frequency).
I disassembled the unit, and noticed that there are ribbon cables from the front PCB to the rear PCB. The attachment at the front PCB uses a very poor quality (IMO) mechanism to attach the cable to the PCB, where prongs penetrate the insulation of each conductor on the ribbon. I believe my problem was that over time, this very tiny connection degraded. I tried removing all the ribbons and cleaning each contact with de-oxit, and also injecting some de-oxit into the mute switches. My problems significantly improved after this, but I still had the left Mid-Frequency cutting out once in a while. I couldn't have that happen at a gig, so I just ordered a new one. It is normal for an item with a lot of strain placed upon it (like a power amplifier) and/or with a lot of shorter-life components (like electrolytic capacitors) to require service after a handful of years. But a piece of gear like this should last longer. Much of the stuff in my rack (including some other Behringer gear) have been going strong for 17+ years. This one failed due to lousy design in terms of the ribbon cables IMO. But, the sound and value are so great I'd still recommend it. As far as Behringer gear goes, this is the only one I've had where I had any qualms about build quality. Their compressors are excellent for the price range (I have an original Composer, a Composer Pro, and a Composer Pro-XL). I think their analog signal processors  are great. I have a DSP-8000 digital EQ/RTA which is good but the D/A converters aren't great. I've owned the feedback destroyers and thought they were decent as well. I hated their Mackie-clone mixers because I thought they sounded like dirt, just like the Mackie. Moral of the story is, some of Behringer's gear is really quite good, some of it isn't. You have to make your purchase decision based on the reputation of the particular model, not the brand name when it comes to the B-word.

I bought a pair of these in June 2011 for $18.99. Little did I know how much of a steal they were at that price. Bottom line: they have amazing sound, specially after a burn-in. I recently lost my old pair (sob) and was shocked to see the price increase. Reluctantly I repurchased. At first I was disappointed with the sound (and price of course), but after about 80 hours of burn-in, they were every bit as amazing as my lost little lambs (still sobbing). In the disappointment period, I sprang for a pair of Klipsch Image S4 which, even after an equal burn in, had no where the sound quality of these JVC's -- specially in the bass department. To boot, the Klipsch suffered from an intermittent, one to two volume reduction after continuous playing. The Klipsch are going back!!! Given music with high compression rates, the JVC's out perform the Klipsch by a wide margin. Yes, they are expensive now, but you won't regret buying them.

I had been looking for a good pair of earbuds for a while.  People seemed to really hate on the Klipsch s4i specifically related to their reliability.  I kept searching and started looking at Ultimate Ears etc but they didn't have the integrated remote.  Then I found Klipsch's 2nd revision and the new product the X7i.  I have to say I am impressed so far.  The new flat cable design makes sense and I'm glad there are no tangles.  The actual buds are very small and look great.  The remote works great with my iPhone 5 and the sound is impressive for how small these things are.  People apparently are concerned about the bass but it's just fine unless you are a person who rolls around with a pair of 12" subs in your car.  Get yourself a pair.

BTW, I rated them a 4 because I haven't had them that long.  If they hold up I'll upgrade them to a 5.

Updated 12/19/13

I am now almost onto my third pair of these.  The first time one of the earbuds started getting fuzzy and I initiated a warranty call and Klipsch took care of me although it did take some time.  The second time one of the buds just completely stopped working which is why I did another warranty call.  I'm still waiting for the next set to come in but I can no longer recommend them even tho I love the form factor and features these offer.  Each pair has lasted for about 6-7 months before flaking out and I take very good care of them.

Very good sound quality. Having owned skullcandys and bose for years, I decided to get some klipsch. My dad has the X10's, and they're amazing. The sound quality on the S2's is very good, however, the bass is more colorful than the X10's, and it has the tendency to draw out high pitched "S"'s. Incredibly good for the money, please get it.

The first one was great. The second one would not pair with the first to make a "stereo" speaker system. The sound produced is very nice and rich in tone.

In the past year, new 2-piece speaker systems from Klipsch, Creative Labs and Philips have set a new standard in sound, especially bass response, for PC speakers under $100.  I have not been able to perform A/B tests with the Klipsch Promedia 2.0 or Creative Labs T20, so I cannot say if this Philips system is better or worse. But it does have very impressive bass, and sounds very clear at healthy volume levels.  It definitely sounds better than any other self-powered 2.0 system I have heard. It's comparable to a modestly priced stereo home system.

  The only drawback would be that these speakers are not really portable. The supplied amplifier is almost as big and heavy as the subwoofer in most 2.1 systems. So you won't want to lug them around with your laptop. But the sound is great!

They're suprisingly good. I shouldn't be surprised, but there it is: They're excellent. Crisper mids and highs than my old set of Klipsch ProCinema 2.1 and Logitech z5500 before that. Decent bass--I'm a bit on the fence of whether or not if they need a sub, they DON'T, but one probably wouldn't hurt either. They have 0 issue getting loud and delivering clean audio. I have half a mind to see if I can rig this up to my home cinema setup. Alas, it will not be so, they shall remain connected to my desktop.

My right speaker on my 2.1 Labtec LSC-3210's finally bit the dust after several years of good service. I want to say I paid $125 for them way back then.
Well, I have always admired Klipsch and their reputation for quality shines through in this new system.
But the kicker is to get this quality in sound for US$125. I never thought I could afford this quality of sound but once I started my search, I ran across several reviews that solidified my decision to spend more than I had planned.
Only complaint would be the lack of a technical specification in their manual.

I bought a set of these for one workstation and liked them so much I purchased a second set for another computer.  They are well-built, good sounding computer speakers, but don't confuse them with actual high-end music reproduction transducers, for they are not that.  Klipsch was a well-known name in the early days of stereo and concert-hall speaker systems, had a bad period (ok, bad decade) where they made a lot of junk, and now seem to be enjoying something of a renaissance by producing things that don't sound too bad at all.

The subwoofer can easily overpower the much smaller mid/high speakers so most of us normal people will never need to turn it up beyond 1 or 2 (unless you're into a physically percussive experience that may damage retinas or other organs).  The construction is high quality, there's no skimping on cable length, and the speaker stands are heavy but bendable steel, making it easy to aim them properly while still remaining quite stable.  I put flat rubber feet on the bottom of mine so they wouldn't slide around.  They do not seem to cause interference with any other device (eg picture quality on monitors), and no other device seems to interfere with them or cause problems (eg noise or crackling).

I'm deducting a few points for the weird DIN plug used to connect everything - if that breaks or you bend a pin, the whole system is kaput. Also in the arena of minor annoyances is that the LED power light is -very- bright, and annoying if it happens to be right front of you (like, say, anytime you're listening to something).  There is no power on-off switch.  The provided stands are about 7" deep and 4" wide, and it appears they can be removed (perhaps for wall mounting).They are matte black and are likely to be quite unobtrusive in most settings (except for that obnoxious LED power light).

Overall very happy with these for general viewing/listening purposes.

My first M-Audio experience was through PC sound cards. Their sound card with the right drivers and Klipsch Promedia 2.1 speakers began my journey for a great PC sound system. This setup performed wonderfully and took abuse for nearly 3 years on an old Dell Dimension 4500 running XP.

I am now running a HP Pavilion w/Windows7 and Realtek HD audio (24-bit, 48000khz sounds best to my ears) into the balanced 1/4" inputs of the AV40. I was previously using the same Klipsch speakers from the old PC and the sound was good, but not as clear and accurate as the AV40. That being said, the Promedia 2.1 was more entertaining for movies and for those who desire the ear-piercing edge of a speaker/subwoofer setup.

I prefer a full range spectrum of sound, and a high quality musical reproduction listening experience. These are great speakers that really do punch as the say. Music from these speakers is of the highest quality, as well as the levels they can handle. I plan to run these with the Polk PSW10 subwoofer, for a nice, full range, balanced system. The AV40 are very well balanced, impressively accurate and clear at all volume levels.

People who want a big booming system may find the AV40 disappointing, but they are the one's missing out. From what I know of the AV40 and read of the PSW10, this combination has potential to be a well-rounded, high performing sound system for many users.

Better results will be found by tailoring a sound system to your needs, rather than expecting to buy amazing sound "out-of-the-box".

5 stars for this system. Buyers, know what to expect.

:)

--------------------------------------------------------------------------------------------------

I recently purchased a Polk PSW10- 10" powered subwoofer that is getting signal from the sub output of my sound card.

This setup sounds much more accurate and balanced than a typical 2.1 system which has the amp, connections and crossovers all in one piece of the system. They are usually set from the factory with little to no adjustment- some allow you to adjust sub volume separately, but this does not change the crossover frequency.

After a few days of listening, tuning and tweaking the PSW10, I have found a sweet spot that makes the AV 40 speakers low-end roll-off almost not noticeable. The sub really fills out the sound spectrum without overpowering the AV 40. It is quite large so if you're cramped for space you may want to consider a smaller unit.

All in all I am very satisfied with this setup and would recommend it to anyone looking for big sound on a not-so-big budget.

I bought these because they have the old style black cones and normal dust caps with Pyle on them . They reminded me of my old Pyle Drivers from 1994 . They have a bit more newer technology In their mechanics and their build . But the one thing that matters most is they sound like my old school awesome Pyle Driver subs . They are way more advanced in their technology and build but the cone structure and it's ingredients must be the original Pyle Driver cone from 1994 because they sound so much like my older , awesome Pyle Driver car Subwoofers . Also they have that Pyle Driver style that really works . Basic Black with a Pyle logo that doesn't scream at you . Thanks for steering away from blue and red subwoofers . I also really like the stitched surround . You finally found the right recipie of old and new Pyle Driver mixed into the new Power Subs . Thanks for bringing back that wonderful Paper cone that the old school Pyle Drivers had . Because those cones have the most natural sound .

I owned this pair of IEMs for about ~1-2 months. During that time I was very impressed with the sound quality. That being said after about 2 months the the right driver went dead.

I bought a pair of these almost 7 years ago.  My kids blew them within a week, and Amazon replaced them free (Thank Amazon!).  After a about 3 years, they started to have problems again.  I thought my kids had blown them, again but it was intermittent. Last year, one of the speakers was sounding really bad.  So I checked the warranty, and I was a couple of months past the expiration.  So with nothing to lose, I opened the speaker, and found out it was very corroded inside.  Apparently, the weather proofing didn't last.  I'm in New England, and Stored them in my basement in the winter (although they are suppose to be all-weather).  I rewired the speakers, and it appeared to work again, at least for a while.  By the end of the summer, it was having problems again.  This year, the speaker was really bad, and the other speaker had no bass.

Time to get new speakers.  This time I went for Klipsch AW-650 speaks.  I think they sound just a good, and they have a life time warranty.  I trust Klipsch.  I've had a pair of Klipsch Fortes since the 80s, and love them.  If taken care of, they last forever.  If something ever goes wrong with them, Klipsch will stand behind them.

Since the Helicon 3 came out, the 2 has become a very good value. The harmonizer features are excellent, verbs and echos are clean and natural sounding, the gates and compression are helpful. There are a lot of features, so it takes learning, but the foot switches are logical.

I'm quite pleased

I posted the following review on the Klipsch forums as well. I suppose it's now far too late to get Klipsch to ever admit that there was a problem since the speakers are discontinued and inventory everywhere is almost completely depleted. It is possible to get them "fixed" by paying Klipsch about $100 and waiting 6-8 weeks...but Klipsch doesn't actually fix them, they just replace the defective part and send it back to you. The flawed design is still destined to fail every single time.
==============================================
I bought mine 2nd hand off of a friend who was moving to another county and didn't want to carry speakers across the ocean with him. Before I bought them I listened to them very carefully for about 10 minutes to make sure all channels were workinig and clean...even blasted it for a few minutes to see if there would be any thermal shutoff. Nope. They sounded great and he gave me the friend discount -- $100 for the whole package.

 When I purchased I was aware of the high failure rate and the overheating problems. I figured that a) the truly damaged amps were lemons, and it wasn't actually a design flaw, and b) most people blowing their amps were probably listening at very high levels. I thought I could dodge the issue by being a responsible owner.

 So for four months I kept my speakers around 50-60 *maximum*, and I always turned them off as soon as I was done listening. Well last week after watching a movie and falling asleep, I woke up and forgot to turn the unit off, dashed off to work, and later that night when I got home the unit was dead, dead, dead. At first I though my 5.1 drivers were bad or something. I tried restarting my laptop, reinstalling the drivers, etc. I just couldn't fathom that the amp would overheat itself into failure mode when there wasn't even any music playing.

 Fast forward through me reading about 500-600 forum posts on this topic, and I now realize that the amplifier in these things is in the class of amp that draws large current even when no sound is coming out. Doh. When I took EE classes in college, we used linear regulators on small projects, but used switched regulators on anything medium sized or above. Having never done any work with analog electronics, though, it never occurred to me that they would use a linear regulator for a circuit this big. It makes sense to me now after reading about the noise issues of a switching regulator, but I was still truly caught off guard. I really think if I had continued to turn the unit off after every use then they would still be working today.

 Anyway, this is a long rambling post which mainly begs to ask two questions.

1) Even if this amplifier is poorly designed and doesn't conduct heat efficiently enough, why isn't there a thermal shutoff before the system fries itself? That seems like the bigger WTF to me. Sure, Klipsch outsourced the amp design and construction, but they could have at least built in safeguards. I'm surprised none of these things have caught on fire. The pictures I found online today of some of these blown amps look like they weren't far from burning the house down.

2) Has anybody here sent their amp to that guy on ebay? If he can be trusted and is still in business, I would much rather spend $60 getting him to fix the root problem, rather than $90 for Klipsch to send me another faulty amplifier. From what I've read, that is all that their amp "service" consists of...

Replaced a 10 year old Altec 3 piece system which I was very happy with, but it gave up the ghost. This system appears to be of similar sound quality. I have it in my 10X12 office and it certainly fills the room with sound without overpowering any of the speakers. I have a Realtek HD Audio card that drives each of the speakers individually so I can adjust their volume to compensate for the where I sit in the room. I was happy with the price after setting the system up.
I did have to replace the main system/woofer box. A day after I installed it I noticed a "POP" when I turned the volume knob past a spot about 10 o'clock on the dial. It "poped" going up or down in the volume, and it would be unstable if you set the dial at that location. I filled out the return form on Amazon and they sent me a whole new unit in 3 Days. I swapped out the speaker that has the volume knob on it first, thinking the dial was the issue, but it turned out to be a problem in the main/woofer unit. Sent the bad part back with the rest of the replacement parts. I was glad not to have to take all the speakers down, re-pack and send back, then re-do the whole install again. I appreciated the easy exchange of getting the replacement first, then shipping back the duplicate. It was less effort to remedy than if I bought it in a local store. Amazon has this figured out pretty well.
