Good but not great subwoofer for PA
922114
The sub works well...but was hoping it would add more "fatness" to my PA.  Using one sub with two Behringer 12' powered speakers.  I may go with two subs to see if that does what is needed.  This is a good price for a good, powered sub.

Built a system for my 2002 Yukon XL, I know, ok call it a Suburban.  Room was an issue as I wanted no loss of utility in the vehicle, I found this was a compromise.  Power is everything to obtain  transparent sound that does not distort at even relatively high volumes.  I chose the Alpine PDX-5 for three reasons  1) it had five channels at sufficiently high wattage 2)  was very small and would fit under the left rear seat and 3) gossip was that although the specs quote at loose < 1% THD it would be clean.  As far as amps go, IMHO there is no such thing as too much power because you only use what the volume requires, it is that simple.  The Alpine is a good amp and my selection of speakers helped the amp a bunch.

Chose two Infinity 60.9cs 2-way component systems sets with  a pair in the front doors and a woofer in the rear door and its tweeter in the very back pillars.  The Infinity's have a very high Sensitivity (93 db@1 watt@1meter), therefore they are very miserly when it comes to power.  The rule of thumb is every 3 db increase in volume requires a doubling of wattage so they are way ahead of say a speaker with a sensitivity of say 87.  They are crystal clear and indeed I hear stuff in the music I don't hear in other systems.

The tweeters come with like (5) ways to mount them and the one that I love and worked for me was a threaded cylinder that has a mating basket that fits in it..  The cylinder permits varying  the depth of the mount (out or into the plane) by inserting homemade spacers and the basket allows aiming the tweeter at what looks like up to 45 degrees!  The tweeters I replaced up front are now directed right up to the front passengers, very powerful stuff.

The speakers come with their associated passive crossovers.  These things are clunky at best and I ended up putting a set under each rear seat.  They could have been made with the corresponding components (for example the coil) being put with its driver (woofer) as an assembly which I would have liked.  Regardless, they work very well as evidenced by the sound.

For the bottom end I required a very shallow 8" for my factory sub box.  Among the vast number of 8" out there (is there another?), I selected the Pioneer TS-SW841D.  It turns out it is a feisty little guy and provides good bass down to 60 HZ, HUG.  No really that is the 5 db down point in a closed box.  It is way better than some 8" in open air in many a car.  What I found that was very important was setting the Alpine's high- pass to the 60.9CSs to 75 hz and the sub low-pass to 75 hz.  Otherwise there is a spike of bass that will give you a headache for sure.  Later I plan to go with a Stealthbox but for now the 8 sounds just fine
By the way, got a Pioneer DEH-P7200HD deck and media selection is phenomenal compared to factory.  Need to use it for a while to be able to comment on usability.

When I'm sitting at my computer, I often listen to streamed music and MP3 files from ripped CDs - I don't listen to  exotic music formats or special high quality CDs.

I've recently been getting back into more serious music appreciation after a gap of a few years. As a result, I recently started to notice the sound quality shortcomings of the under $100 2.1 speaker system I had been using with my laptop.

After spending a bit of time looking into new 2.1 systems I recalled that I had a nearly-new pair of Bose 141 speakers sitting unused in a box. The 141s were a well-respected speaker in their day, and probably significantly better quality than most of the speakers I had been looking at. The 141s are un-powered speakers so I knew that to use them with my laptop I'd need to get a power amp.

After a bit of research into power amps I found myself looking at the SA50. It appeared to have everything that I needed and for a price that was reasonable.

The SA50 feels solid, and the power switch and volume control have a quality feel. The connectors on the back are tight and solid. The unit has been in production for a few years, which gives the manufacturer time to work out any glitches that have been identified. There is no bass and treble knobs, but I rarely use them. There is no balance knob either, but balance can be adjusted in the computers sound control panel. So the simple layout of the SA50 works for me.

People often worry if the amplifier puts out enough power, and manufactures don't exactly help clear this up. For example, the 141 speakers I'm using have specs calling for a receiver or amplifier output of 10-80 watts. So, will the SA50 put out enough juice? And just how many watts does the SA50 put out anyway?

The manufacturer claims 50 watts per channel for the SA50, one reviewer pegs it at 30, another claims 19. In any case I was pretty sure that it was more than enough for my application - to power small bookshelf speakers in a home office setting.

I say that because In the mid-70s I owned a pretty high-end quadraphonic system (a Marantz 4100) that put out a whopping 25 watts per channel - albeit into four channels. When I cranked the volume on the 4100, the four 50-pound speakers I had connected to the 4100 - each containing a 12" woofer - were loud enough to wake the dead. So I felt confident that the SA50 put out enough power for my little 141s.

And the output of the SA50 *is* more than adequate - zero volume on the SA50 is at about the 7 o'clock position on the volume dial, a comfortable background listening level given my setup is at 8 o'clock, uncomfortably loud occurs at around 10 or 11 o'clock, and the 100% power label looks to be at about the 5 o'clock position (not that I've tried going anywhere near that loud).

I also added an inexpensive Monoprice powered subwoofer to the mix and added a USB DAC as an alternative to just running a cable from the laptop's headphone jack to the SA50. For what it's worth, *I* didn't hear any difference going through the DAC but I use it anyway.

So, how does the SA50 sound? Nothing short of fantastic. There is no hiss and no distortion that I can hear at the volume levels that I (can) listen to. Since the speakers are angled towards my ears, so as I sit at my desk it's almost like listening to headphones - but without the headphone pressure on your ears and head. The SA50 and my speaker setup sounds really great.

For my application, I could spend more on an amp to power my 2.1 desktop speakers but I doubt that *I* could hear the difference.

I'm no audio wizard by any means, but I've gone through a few subwoofers in the quest for the perfect sound.  I now own a couple of Jamo 660's and am very lucky to have found my second one as they are no longer sold in the U. S..  My recommendation is to buy one while you can.

With those 12" subs they should sound substantially better than they do. The box isn't made well so it doesn't allow the air to travel correctly.

Want too sure if getting a $200 sub was adequate whe compared to the bestbuy subs at a higher price. Whent ahead and purchased because of the reviews and I haven't regretted it. My old Denon sub died from an MCS95 boston acoustics system. This sub puts that sub to shame. You literally feel like 18 wheeler just park next door its that good. For movies and games I highly recommend. For music not so much. I don't know why, not an audiophile here, but it sounds weak for music. Maybe its a seting i have on or something.

The only reason I'm giving this sub a high mark is because he plate amp at 2 ohms is incredible. The amp "farts" because of the capacitors in it get charged from the current produced from the sub moving because of sounds around it. Get a high Q sub that's 2 ohms and sounds good in a 2.5 cubic foot space and you've got incredible sounding sub. I've got an old Audiobahn AW1200 in mine right now and I'm having a hard time wanting to remove it.

Plate amp gets hot but pounds music long time...

I bought this speaker for midbass I have a 15inch sub for lows and all jbl speakers I'm adding this for some mids and because I have a channel on my amp that's not being used. Its okay if you put 40-60 watts on it but 300 is crazy. Its a good deal for $13 just don't expect a big difference just if you need to fill in some missing bass notes.

If you're looking for an entry level turntable, have a lo-fi sound system and aren't picky about not hearing any low frequencies during playback, go for it. But if you like hearing the full spectrum of sound available to the human ear keep looking. Based on the reviews I read I figured there HAD to be something wrong with my subwoofer connection since nothing was coming out of it. But no, in doing some A/B testing with a more sophisticated setup in another part of the house, it appears that the built in preamp in the this turntable is just not good. I plugged the AT-LP60 into a $200 preamp on the phono setting and it sounded SO much better, but when using it in a modern audio setup with the line out setting it's thin, lacks appropriate gain and any significant low frequency output. I'd rather spend two or three times as much and get a decent built in preamp stage that provides adequate output.

This is a solid mini amplifier.  The build quality is very good.  The volume knob turns fine and I like the fact that there is a power button.  The blue light around the volume knob is subtle and looks cool.  But the power ratings are overstated and the reviews are a bit over hyped.  While it does have decent power for a mini amp, I did not find it as loud as others described.  Perhaps because I am using it with small BIC DV32B speakers with 3.5 inch woofers for TV sound and music.  It starts to distort when approaching the 1 Oclock position on the volume knob.  I haven't tried this amp with bigger speakers but if I do I will update the review.  I replaced the SA50 with the SMSL Q5 Pro mini amp and it plays cleaner using the same speakers.  The Q5 Pro comes with a remote and has optical, digital coaxial, USB inputs and a subwoofer output.  It also has a built in DAC.  But it also costs about twice the price of the SA50.

I also own the Dayton DTA-120 Class T mini amplifier.  I find the DTA-120 to be louder but more importantly it sounds much cleaner.  The SMSL SA50 may have some kind of bass boost that may be the reason it does not play as clean.  On the DTA-120, I can crank it to full volume without distortion- Really an exceptionally clean mini amp.  Thats because it has a power rating of 40 watts per channel at 8 ohms and 60 watts per channel at 4 ohms.  While the SA50 boasts 50 watts per channel its overstated.  From what I have read online, its more like 20 watts per channel at 8 ohms which is OK.  While I like the Lepai LP-2020A+ (and LP-2020 TI), the SA50 is definitely a step up and more powerful.  But it would be nice if both the SA50 and DTA-120 had bass and treble controls.

In the end, while I like the SA50 I much prefer the Dayton DTA-120 and would recommend purchasing that amp for only a few dollars more.

i had some of these the rms is abt 650 to 700. my amp was a punch rms was 700 and i never blew them.  with that  little wattage all you really need is a good sub crossover. for pretty decent sound. if you're looking for some pretty good subs pennies on the dollar you can shop by wattage at sonicelectronix.com

I really like the sound of this soundbar although certain tracks sounded flat. There is no eq to correct this. I bought this thinking it had the same features as the micro w but found that the W studio does not allow you to add surround speakers like a comparable Sonos model does.  The surround is noticeable but not full enough to enjoy while watching movies. The stand out star of this system is the subwoofer!! It surprised me to say the least!!! It is a very good sounding soundbar but lacks fullness with it's surround and can not be eq'd to remove flat spots. If i could do it again i may sacrifice the the sound quality difference and get the sonos so i could add surrounds to it.

Didn't that good through a PA. Got complaints from the sound guy. Didn't expect much and it met my expectations. It does work, though, and I may still use it in some situations, but I think I'm going to try to find a better pick up for my resonator.

I have the DSWPro 500, and I like it. It's a decent sub for the money. I've heard better subwoofers, but they are much more expensive. This one does an reasonably good job at a very good price. I'm happy with it.

I bought a set of these speakers from local retailer at the steal price. I'm not an audiophile. All is just from my experience with this set. Hi and mid are ok for this size of speakers. Do not compare to those bookshelves and floorstands. Soundstage is NONE but who cares? The subwoofer itself is small (6") but give you "enough" low/bass for a small system. At this price, it is one of the good sets. What I don't like about this it is the Volume disc is wobble plus the blue LED is a too bright for a dim room.

I have owned several budget subs in the past ranging from the polk psw10, 202,505, paradigm pdr10, kenwood, and the jbl es250 has the lowest extension of them all. The only thing about this sub is it can be over driven in the low notes since there appears to be no limiter. I think the psw505 has the most output, but the es250 has a better response from 25-100hz.
