Let me start with the negatives, it's not as loud as I thought it would be for the size that it is. That 6 inch subwoofer on the back is not really a subwoffer sounds more like a mid-range speaker than Bass it's playing mostly middle.  It's distorted on me with heavy bass in a song and it buzzes really loudly when you have it plugged into the charger and try to use it at the same time.

The speaker does have a few positives, the treble is usually very very clear and not annoyingly so.  For the most part it sounds clear.  It does get loud enough to take outside and play with a small group of people. I like how it's very important that handles make it very easy to carry and it's not very heavy at all.  I like how you can adjust the bass even though there's not much to adjust on it.  And the build quality seem solid other than that I don't think I'd recommend the speaker unless you're looking for something that's ultra-portable and you can carry around and use at a get-together.  I think I'm going to use it in my wood shop at work.

I do have the flat black one and I can say it's a very clean-looking unit.

The speakers are locked up in manufacturing, so bass doesnt go too low. Pair with a good set of subwoofers.

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.

What is this "great bass"  that I keep reading about?
Doesn't anyone know anymore what real bass is supposed to sound like?
Well, this is NOT what it's supposed to sound like:  when bass setting on the Z623 is set half-way (middle)  the bass sound from the woofer unit is so distorted that it's unlistenable.  And I'm talking about very moderate volume.
When turning the volume up a bit (but still leaving the bass setting mid-way)  there's this loud buzzing, rattling sound coming from the bass unit.
What's happening is the bass speaker is being way overloaded;  severely overloaded.
I'm using this system with a normal laptop, playing music from MediaPlayer and other music software.
I bought it to replace a Microsoft Digital Sound System 80,  a computer speaker system same as this one with 2.1 sound and the base speaker unit containing the electronics AND the 8-inch subwoofer ... with an 8-inch passive radiator.  Size and weight are approximately the same, but the sound??
Wow! what an immense difference, especially in the bass.  That Microsoft 80 could make the windows rattle .... without ever bottoming out.
The MS 80 unit is almost 20 years old and has been in constant use;  so recently the rubber seal of the passive radiator just gave out: crumbled slowly into many pieces.  The actual woofer speaker, mind you,  is still in perfect condition,  but needs the passive radiator to function properly.  (I investigated and found that a repair kit for the radiator costs about $70  and I would have to do the semi-difficult gluing repair process myself.  So that's when I decided to try this $100 Logitech Z623.
Frankly, I realized that any similarly-priced replacement system would likely not be as good,  but I was willing to lower my expectations .... just 'cause I'm lazy, I guess,  and didn't want to hassle with gluing repairs.
Well, to say that my expectations were severely dashed is an understatement:  that 20-year old MS 80 system sounds NOT twice as good,  NOT 3 times as good,  but much, much better than that.  It's got me speechless, actually,  about how bad this Z623 is by comparison.  I'd never have expected it.  (I've owned numerous Logitech products over the years and usually been very pleased with them.)
Oh ... the mid/high range speakers sound pretty decent .... at least as good as those from my MS 80 system;  so maybe,  if you only listen to speech or music without bass,  this might be a good selection for you.

So do yourself a favor if you're thinking of buying these:  buy them from a place where you can return them if not satisfied.  Perhaps check Amazon Warehouse deals,  since my set may turn up there very soon.

This is  more of an amplified woofer than a SUB woofer. The cross over adjustment has a very small range and can not and will not enable tuning for an even slight tight bass response. The response is not tight and is more of a muddy response. This has a lot to do with the quality of the amp which is not fast or powerful enough. This is strictly about the sound and due to the very low price point is expected. If price is a main factor choose a smaller diameter driver and a more powerful amp and it may give you tighter response which is really what you will want.

Better bass and more volume than the slightly smaller or less powerful 6 watt speakers. The mids do not seem to be very clear in comparison to other units. The speaker will "walk" itself across a flat surface with the bass, which could lead to it falling off of a high surface. I can't comment on the battery life because I haven't used it for an extended period of time yet. I'll update with info on whether there is background noise when using while charging.

I guess I did not realize that the subwoofer would be so large; and in that it does have a subwoofer I expected the volumne control to be better.  The volume is very limited.

The sub woofer is OK but the surround speakers are awful. Luckily i have surround speakers and I only wanted the amped sub. If you want good sound, spend a little more money.

these things crank. Lack a bit in the low in ...but come on, it's a 5 inch woofer don't be a dork. they do offer a subwoofer for this set-up.

Just can't get the proper level of bass to it, other than that. The mid and high is working perfect.

The subwoofer is good, the speakers are good.
Good sound quality on any sound level
They should add more cable to the speakers or consider a Bluetooth speaker

If you are all about that bass, this is not for you.  Sounds great,  but not much bass

It doesnt quite have the bass you would expect out of a subwoofer, and the sound is tolerable.  It cannot be compared to the $100 speakers, but I will say if you are looking at speakers under $40 these are definitely worth a shot.

the bass is a bit artificial but for the price I think it is good

For some reason the 5.1 channels don't work the  way they have to the sound it's pretty bad.  To much bass on front and rear speakers and when  you turn down the bass on the settings no enough bass on subwoofer  it should have some kind of filter for front and rear speakers

First off let me start off by saying I have been in to car audio for about 15 years and I have owned and installed every type of subwoofer from the top of the line to the cheap flea market speakers. I restore and sell classic trucks and cars for a living and I bought the pyle 10 inch sub to keep cost down on a truck I'm restoring. I put the sub in a custom sealed fiberglass box with about .75 cubic foot of air space. I'm running about 100 watts rms at 8 ohms to the subwoofer and it maxed out the speaker. I think if I add more then 100 watts to the sub it will blow. Now for the sound quality, it's actually pretty decent as long as you keep the watts low so the sub won't distort. I would not use this subwoofer in my personal vehicle or recommend it to my friends.

-Update
I took the truck out today for a cruise and the speaker blew. Didn't even last 5 songs :(

For the most part this a good sounding speaker but the passive sub woofer doesn't seem to add much to the sound and the max volume level is less than I was hoping for.
