High quality speakers, but with defects

I've had these speakers for a year and a half, and they are fantastic quality. Great clarity and rich bass. The extra jacks on the right speaker are super convenient, although it is quite difficult to plug cables into them because you have to push very, very hard. The biggest problem for me is the defective power button. Occasionally, I will have to turn off and on the speaker when I power on the speakers because of crackling. The power button is also very sensitive, so any brushes against it will cause crackling. I am concerned that the power button might break in the near future.

Too raspy of a sound - harsh unlistenable

I have bought many PC speakers including nice Logitech brands, so I thought I would now go all out and get this super larger model with the big bass box with bigger midrange/tweeter satellites and even the nice controls. I was hoping for a bigger better sound than my smaller Logitech. What a disappointment. I tried so hard to like them, but the raspy overpowering harshness of the satellite speakers was just horrible. I was so disappointed and I eventually returned them. I am shocked at the higher ratings. I did not want to chance another pair.

All PC Speakers

FYI... All pc bookshelf speakers that have a rating of 200watts (like this model) or even at 100watts for that matter is a "gimic" to get you to buy them. I've been a sound and lighting engineer for international rock and pop bands for about 36 yrs. About 99% of pc speakers have a top max wattage of 50watts... and that's pushing it. These speakers are about 18watts each. Let me explain... when a DJ performs at a small party he/she brings in speakers rated around 150 to 250watts. These have enough sound to fill a good size school classroom with enough volume to satisfy most. These pc speakers barely fill my bathroom with sound. When pc speaker manufactures put 'wattage ratings" on the speakers, they are actually trying to impress you by saying they are 200watts. These speakers are great for what you'd want for your pc, but won't give you anywhere near 20watts or even the "rated" 200watts claimed. Next time to look at pc speakers specs, do not buy just because of the wattage rating. Go with with the formula of 100w divided by 10 = 10watts. Or 200w divided by 20 = 20watts. Look for pc speakers that have a min 4" or larger inches subwoofer and the tower spkrs that have a mid and high spkr in the enclosure. Any pc speaker system that comes with a sub will be your best set-up. I own "Logitech Z-5500 THX-Certified 5.1 Digital Surround Sound Speaker System"

Worth Every Penny

I was surprised by these speakers. I wasn't looking for anything particularly powerful but I did want something that would reproduce crisp notes on the high end and enough bass on the lower end to not "Sound like" bookshelf speakers. I put my faith in the THX label and bought them on-line. I use these in a home office environment and listen to them mostly while working. Well, they sound great and faithfully reproduce all ends of the music spectrum. Having power and bass buttons on the speakers themselves is a nice touch that I use more than I thought. As for power, I rocked them on the first day. I was more than impressed as they actually moved the pictures on my wall - enough said.

It Was Great For A Few Months.

I bought these for my computer about a year ago. The sound quality is phenomenal and the bass is amazing! The only thing I don't like about these speakers is that the buttons wear out fast. After about four months I have been having to wiggle the power button to make the sound work, the bass nob sometimes sticks, and when I turn up the volume I can hear static coming from the speakers (when there is no music/sound). Other than that, it is a great product and I am still very happy with the purchase.

Had to replace 3X

There's no reliability despite the great sound. Ive literally had to return them 3x for the same issue, sound distortion, and now the sub has completely cut out. Its a bit ridiculous.

Maximum volume is not loud enough

Good sound quality but the maximum volume was just acceptable. The sound was not loud enough as compare to the previous Logitech model with the same power output of 200W RMS.

Unreal

I've never really been a fan of Logitech, but after reading the reviews online i decided to try them out. Best speakers I've ever use, no joke. Got them at a good price via black Friday, and they have very deep bass, convenient knobs, and good mids and highs. I did notice a slight whine when I first bought them, however it went away after a day, and I only heard the whine because I was looking for it. Well, listening for it. Not sure why, but yolo. Definitely worth it.

Love them! Just bought my second pair

I've owned a pair of these for about six years. Well they've had beyond what I'd expect speakers to last for usage. From lots of parties to lots of days cranked for hours on end. I can't say there's been many times it's been past 75% as it's way too loud. However they've stood the abuse and test of time. They are amazing for bass and sound. Hence why they died tonight and I went and bought another pair. For the people who talk about a high pitched whine, any speakers get those with interference from radio or wifi signal. Also if you have the cable in the back hooked up compared to the side of the speaker there's a proper way to do it. My only complaint is I'd like an hdmi hook up for gaming, but these are computer speakers and as great as they are it's not a surround sound unit. Overall I'd buy these again and did. Amazing especially for the price!!!

Wow wow wow!

This is a fantastic system! Have a Z2300 in the kitchen and wanted something comparable in the living room. The Z623 more than delivers. Great pounding bass (if you like it like that) and incredible all-around sound. Love it!!!

High Pitched Whine

High pitched whine comparable to dog whistle when speakers are turned on. Whine does not change in volume when you increase so you can listen to music nicely at a high volume, but very annoying at low volumes.

Almost perfect

The sound quality is phenomenal as is the volume that this system can generate, my only complaints are, the knobs are hard to read because the levels are black instead of white. Not a big deal though so I just painted them and the speakers don't come with regular speaker wire so if the amp goes the whole system is useless but other than these two minor quibbles, these speakers far exceeded my expectations.

Very good

I've had these for a little over a year and I use them frequently at very high volume. They perform VERY well for the price. I tend to blow speakers frequently but these ones just wont blow. The subwoofer cant handle certain songs above half bass volume, if you have the main sound turned up. You will hear it struggle sometimes... but seriously you dont need it on a very high volume, its plenty loud at half volume. It shakes the house at half volume. The ONLY thing that has gone wrong with these is the power button, sometimes if i hit it when reaching for the volume knob, the subwoofer cuts out. It;s not a big problem they still work great! GREAT for music movies and games! Dont think twice about these, they are AMAZING for under [Price]!!

Absolute value for money

Great for home, small-medium rooms, also can work in a large hallway but would prefer higher RMS speakers. Works best when paired with a THX sound card like Creative Sound Blaster. I also have an SP-2500 from Corsair, compared to that these are of great value for money. Sound is clear, rich, good bass and clear vocals. Don't think too much, go for it.

I love my speakers

I listened to a set of these in Future Shop 5 years ago and fell in love with them. A few months later they showed up in the Boxing Day flyer at a price I couldn't resist. They are the best computer speakers I've ever heard.

Best Boxing Day Product!

I bought these speakers online during BestBuys Boxing Week Sale. They were scheduled to arrive 10 days from purchase date but arrive in just 5 days! This gave me some more time to try them out before I went back to work. I was blown away by the clarity and power! I'll be watching the BestBuy ads if and when they go on sale again. I want another one for my computer downstairs.

Researched this item and reserved it for p/u at store. Amazing sound and everything!.. with Bass set at even it soun ds far better than any thing the competitor sells.

Awesome Speakers for the price

These speakers are freaking awesome. Thumping bass, awesome sound quality and great for music and games. The cable for the right satellite speaker is pretty short, but that doesn't matter much since they work well. Overall best purchase I have made aside from my pc. I would recommend these to anyone who loves clear sound and thumping bass.

Great sound

I wanted to buy a nice 2.1 speaker system and after much research I finally decided to buy the Z623. When I first powered them up my heart sang with joy after I heard the heart thumping bass and the crystal clear sound. After a couple of days I realized that the right speaker with the controls on it didn't work when the volume was turned low. Only the left speaker worked. After reading similar problems on various forums I learnt that it is a defect and is not a design issue that some users thought. I exchanged it for a new set and these work perfectly. Balanced output on both speakers at any volume. So go get these and have a blast... :)

Error in the design

I'm very disappointed with these speakers and I can only advice everyone to stay away from them. Basically as soon as you turn the volume down the right satellite actually becomes so quiet you cannot hear it anymore while the left speaker is still quite loud. Only when the volume is above a certain level both speaker will actually be at the same sound level. First I thought I got a defect product and I exchanged only to encounter the exact same issue on the new one and apparently the error lies in the actual design, because the left speaker is on a regular audio jack while the right one has a fancy plug to support the power, volume and bass adjustment. In short do yourself a favor and get a different set.

Excellent sounds, cables could be longer

I listen to EDM and wanted something that would work well for music at my computer desk. I'm happy with this speaker set, just wish that the cables were longer. The hole in my desk is not placed in the most optimum spot for shortest route, so I've had to put these speakers in less than optimal positions.

Beyond my expectations

After reading reviews from others, I decided to purchase this system. The sound is absolutely incredible considering the price and size of the system. After listening to them, I have to say that it's one of the best purchases I've made in a long time. If you are looking for a small system with BIG sound, then these speakers will not disappoint.

AMAZING

I bought these on sale for [price], the sound is amazing. It gives good dynamic range and fills a good sized room. The Overall sound quality and frequency separation is well balanced from the subwoofer lows to the mids and highs of the satellites. Can't beat the sound quality for the price of these speakers.

These speakers sound awesome for the price

I got these speakers on sale and they were only [price] more than the pair I returned to exchange for these ones. That was the best [price] I have spent in a long time! These speakers are LOUD and sound great. Lots of volume, tons of bass (you can adjust down if you want). I used the built in EQ on my soundcard to tweak them a bit. I have them hooked up to a PC that I am using for a home entertainment system along with my 50" TV. They fill my living room with sound at 1/2 volume without any hint of distortion. I use them for listening to music, watching movies, and gaming. The only downside is that they only have 3.5mm audio in or RCA connections, no optical in (I bought an optical audio to RCA converter to use these speakers with my TV). However, given the price this is not really a big deal. I would definitely recommend these to anyone looks for big sound from PC speakers that take up very little space.

Average Over Priced Speaker Set

Although decent speakers, they are over priced for the sound quality and volume. They sound plastic, and when pushed they distort. I find that 200 watts on these speakers is not at all like 200 watts in the old days. Their price range should be cut by at least 50% to even consider value. My 3 point rating is based on the price I paid.

Better than the predecessor

I am really impressed by these speakers. I initially bought them for my laptop, but these are too powerful for it. I am now using them for my 60" TV. and I am very happy with them. Impressed with the Bass and impressed with the overall sound, so these are good for entertaining and also for music. Very very happy with them !

Great speakers BUT..

So I read all the reviews for these and waited till they went on sale before i purchased them. My initial reaction when I opened the box was good, they look really nice, the sub is heavy and seems well made. Once i got them set up, (takes about 5 minutes very simple setup) I powered them on and there is a bit of static noise and a very noticeable continuos high pitched noise coming from both speakers. Even when the speakers are being used on low volume this sound can still be heard, it did go away fully for a couple minutes then returned and it is very irritating. I tried all the troubleshooting, I've tried moving them away from other devices, using them on a different device, plugging into a different outlet. Nothing seems to work. And to make it even more annoying when i plug headphones into the right speaker headphone jack the sound disappears and does not play through the headphones or the speakers. I am going to exchange them for another set and hopefully this doesn't happen again. These speakers are excellent other than my isolated issue, very powerful, huge bass, look sweet on the desk and easy to use and set up

Great Choice

I tested and watched reviews for 2.1 systems, i went with the Klipsch Pro Media 2.1's, they were poor. Listen to speakers with pillow over your head and that is what these were like. Bose Companion's needed to be in a small room to work, i do not know because my room is large. It failed, not enough power to fill a room. I replaced my Logitech Z2300's with Logitech Z623 200 w system. At half power this unit filled the room, bass is way over the top. I have a 14X37 foot room with vaulted ceilings , this i would recommend .For less than half the price of the Bose and 60 bucks less than the Pro Medias I love this unit a bargain , a great upgrade. No cons what so ever.
