Ratings & Reviews+

Logitech 2.1 Channel Computer Speaker System Z623 is rated 4.7 out of 5 by 63.
Rated 5 out of 5 by from No Better Speaker Value on the Planet This is the fourth set of speakers I bought for my small 32 inch home theater. The others cost $75 to $100, all sounded very good; the best were Genius SP-HF 1800As, an excellent choice for the money. Still, I wasn't satisfied and wanted more powerful speakers with more punch at the low end. I'm thrilled with the Z623s! The clarity, definition, and sound stage are remarkable. To my ears the quality of the audio equals that heard in a commercial movie theater. If you've planned to pay no more than $100 for speakers, I urge you to spend a modest $34 more and get these! It may be the smartest purchase you ever make.

Rated 5 out of 5 by from Definately worth it I own a Alienware Mx17r. Me and my girlfriend use it frequently to watch movies or play games/surf the net. These speakers have exceptional sound and quality .They are pretty killer when watching 3d movies you almost feel as if your right there in the action. Im an avid gamer playing games like COD 4 and Quake 4 the sound is almost scary. I gave it 5 stars all the way i believe there definately worth the price and exceeded the sound quality that I was expecting. Mad props to Logitech for building an exceptional speaker system for laptops/pc's. I highly reccomend these to fellow soldiers who love to game.

Rated 5 out of 5 by from Phenomenal! This system is incredible, and competes with systems costing far more! I ruled out the Logitech Z 506 because the clutter of six speakers in an already cluttered space made no sense. The Z 623 is the only system that's THX certified which is George Lucas' company certification, which means very high quality. With 200 Watts, I was concerned how well the system would play at very low volume late at night so I don't disturb my neighbors and was told that with THX cert. it will play great at any volume - it does! The THX is right on the speakers at the top in the photo. It's whisper quiet on low and turns up very gradually and sounds great all the way! It's got so much power, I haven't gone above half volume except to test it and usually am between 1/3 and 1/2. The huge sub woofer truly rumbles when it needs to with NO DISTORTION, and I usually have that at less than halfway also. Highs are crisp, and midtones are full. Tested it with Star Wars and it blew me away! There are inputs for headphones and other audio devices as well.

Rated 5 out of 5 by from Great speakers for the price Great speakers for our computer. Had bought a set that had 25watts of power but wasn't pleased with sound. These have 200watts of power and give great sound. Can here through out house without turning volume to max. Well worth the price.
