Detail Review:


Logitech Z623

The Logitech Z623 is currently retailing for around a hundred and twenty dollars and these are one of the speakers from the Z series of Logitech speakers. These speakers are 2.1 speaker systems which mean it comes with two satellite speakers and one subwoofer.

Logitech Z2300

The Logitech Z2300 is also a 2.1 speaker system with two satellite speakers and one subwoofer. These are also THX certified, so these sounds really good for movies as well as games. These speakers are currently retailing for around a hundred and fifty dollars.

The subwoofer itself is quite heavy and it is a sealed box. There are screws on the back where the connection ports are but the box itself is sealed up. It only applies to those bass heads out there who are handy with a soldering iron and who will do their own speaker repair. If this subwoofer ever goes out, if the Amp goes out, you’re not going to be able to repair it easily. I mean you would pretty much have to destroy the speaker box in order to get to the internal workings because not everyone knows how to recon a subwoofer.

Logitech Z2300

There is actually a vented on the side of the subwoofer from where you can feel a lot of air coming out of that. These are really good speakers for a laptop but they’re just not. I mean this subwoofer is too big so if your dest is small then you can’t place it on your desk. But you can place the satellite speakers on your desk as these are small in size and don’t take that much space. You are getting a small remote to control the volume on these. There is a little notch for the volume which you can turn all the way up and down. There is also a bass knob for the subwoofer and a power button on and off the system.

Inside the box, you get two speakers, some cabling, some instructions, and the subwoofer. It’s pretty straightforward how you hook this up. You have some connections behind the subwoofer, the RCA audio input the main speaker that drives it, and also all other connections. The satellite speakers feel very substantial, they’re very nice, very quality, nothing negative about them.

The proprietary cable looks like a VGA cable. Cables like this were used to connect large heavy bulbous monitors to computers. I was shocked and stunned to see this type of connector on a brand-new set of speakers because you cannot get a cable extension for this. But actually, it looks like a VGA cable however the pins are wired differently so it’s not exactly a VGA cable ie a VGA cable extension will not work.

Logitech Z2300

The Logitech Z 2300 computer stereo system is THX certified which is basically a quality control rating for it. It’s really built well and is extremely worth $150. It pumps out 400 watts of peak power and that means it’s gonna get up to 400 watts which is a lot but I don’t think anyone’s going to take up to 400 watts unless you want to blow all your speakers. It has 200 RMS power which is the square and that’s just gonna be it can pump out 200 watts continuously which is pretty good in my opinion.

For connection you have a big table with the control pad or the remote that’s gonna the subwoofer and all the connection ports are there behind the subwoofer. Then you have the PC port and then above it, you have left and right the yellow one is left and the black one is right but those go up to the satellite speakers. The control pad’s port comes next to it and it has the input on the volume control, the audio input, and the volume control for the subwoofer, and the subwoofer itself has the power switch down there in it’s back.

These speakers have thunderous bass, crisp highs and mids, and all that great sound. I tested out the sound quality with the volume at maximum like as far to the right as it can go and I didn’t hear anything coming from the speakers, there’s no hint of static or noise or anything. That is ridiculously loud I have it set at 3/4 volume that was way too loud.

Logitech Z2300

The subwoofer sounds so good as a Bose without turning on all the way up. These sound very loud and with the THX certification, these sound very good for movies and games. The bass is really good and punchy. The satellite speakers too sound good but with the single driver, they don’t produce better sound.

Logitech Z2300


In my opinion, you should buy the Logitech Z623 because it’s sound better than the Logitech Z2300 at a lower price than the Z2300 and also, it doesn’t have any extra remote like Z2300 and has all the control system within one of the satellite speaker, which is really good for the price.

Expert Reviews of Logitech Z623:

By Tech Digest
They’re fairly pricey, but gamers and movie fans will get a lot out of the Logitech Z623 speakers. Superb bass response and an excellent stab at immersive THX audio make them easy to recommend, even if the satellites lack a little in detail.

By Tech Radar
They have to be heard to be believed though, and despite our reservations about the THX certification, it actually seems to mean something here. These come highly recommended.

By About.com
The Z623 is an option for gamers or movie buffs who want the power of a 5.1 system but not the price or added hardware. All other users need not apply. Disclosure: Review samples were provided by the manufacturer. For more information, please see our…

The Logitech Z623 offers powerful stereo sound at a price that can get as low as £110 in certain online outlets, which is attractive. The system sounds bold and offers powerful deep bass that makes it easily a good option for partying or waking up…

Well-designed and incredibly loud, but the audio just doesn’t sound as good as we’d expect from an expensive 2.1 set…

Expert Reviews of Logitech Z2300:

By cnet
Logitech’s Z-2300s have been on the market for more than half a decade, but these PC speakers still pack a sonic wallop.

By tomshardware.com
The Z-2300, based on Logitech’s 2200, will serve as a reference point in the world of high-performance 2.1 speakers. While we would have preferred to see the satellites offer two-way drivers, the final result is that the speakers are at the high end of the quality spectrum. 2300 thus represents one of the rare possible choices in this product sector for those who seek the best in the category.

By Dark station
The one thing for me that really held these speakers back from being the top of the line is first the size of the subwoofer which is a bit too big for my tastes and second off the high price tag which is enough to come close to buying you a full surround sound setup. With that being said if you are looking for a high-quality speaker system then you can’t go wrong with the Logitech Z-2300.

By Home Theater Review
For the money, the Z-2300 offers a good blend of benefits. The Logitech system provides good sound quality for movies and games, a nice array of convenient features, and some crisp cosmetics. In a world where downloads already control the music business and are quickly taking over for DVD as the preferred way to buy and own movies, your computer needs proper speakers and the Logitech Z-2300 could be just what the doctor ordered.

By Pocket now
I’ve always been partial to offerings from Klipsch – I’ve owned many of their products, and to me, they represent a very high level of quality. I expected the ProMedia 2.1 THX system to remain the king on the block even with, but as indicated by the ratings above, Logitech has brought to the market the next champion in high-end 2.1 multimedia audio.
