Summary: I previously owned the X623's predecessor, the Z-2300, but after a year those died and I got them replaced with these speakers with the warranty. But those too quit working on me after a little over a year, again I replaced them with the warranty and got a new set. Today, less than a year later my set of Z623s are displaying the same symptoms of my previous set and are cutting in and out.
Summary: Okay for outdoor party, I guess but inside it has little to no finesse. I'm not a sound snob, but come on. What a let down. I wonder if companies pay people to write good reviews or if people are really just that un-sensual.
Summary: SUBWOOFER COMPARISON Z-2300: The subwoofer is huge, in every sense of the word. The behemoth measures 11” (H) X 11” (W) X 15” (D), and its output could both rattle the paint off your walls & take the wind out of your lungs at the same time. The enclosure is very deep, which is great from an acoustical performance viewpoint. The subwoofer weighs 12 kilograms and is a back breaker for sure. Actually, this subwoofer was designed for Z-560 way back in the year 2000.
Not great for music - not well balanced, overpowering bass!
1 November 2012
Summary: I'd describe myself who someone who likes good music and good quality sound. On a scale of 0 being not caring about sound, 5 being 'normal', and 10 being crazy audiophile, I'm probably around a 7. If you are a 5 or below on the scale, these speakers may be OK for you, but if you are a 5 or higher, read on... Bottom line: These speakers are not well balanced.
Summary: Sitting here so disappointed after sending in a broken pair of z2300s and receiving these z623s....there is no comparison. definitely don't make them like they used to. hardly any bass compared to the old model. it's sad they couldn't maintain the quality of the old system. poor sounding speakers overall.
Summary: Reading the reviews convinced me to purchase Z623 but I can't believe how poor the performance is. I am investigating a suitable sound card that will improve the sound quality. Tinny sound compared to my 30 year old Altec Lansing ACS48 speakers. Not an audiophile but I know rich quality sound when I hear it and these speakers are little better than the $15 junk I bought for my laptop. Logitech is generally a great name but for now these speakers don't make the grade.
Summary: Amazing Speakers, or should I say speaker. First and second time the left speaker arrived dead. I checked everything and it makes a annoying sounds when I plug the jack in but it does not play. That is twice in a row. I read other reviews that said this but decided to take the risk. I am 0 for 2 and I had it with trying to order speakers. The annoying part is the one speaker and the base that do play, are freaking amazing.
Summary: Bought the set from Best Buy after many positive , glowing reviews here on Amazon . While the power rating may be there , and THX certification is claimed ( which I doubt highly ), these are weak sauce . Do not enter this sauce into the county fair ... becuse it will lose . The main speakers sound very tinny and and without the bass module , they would be as worthless as those un-powered speaker sets you used to have for your old discman .
Right Speaker with Sound Controls - Cable too shor
21 June 2012
Summary: Cable to connect the Right Speaker with the System Controls to the Subwoofer is extremely short and worst, I can't find an extension cord. May work for some people but not for those with limited space and/or flexibility, e.g. I had to install the subwoofer beside my Tower PC on the floor, I'm afraid the vibration will end up damaging my hard disc drives...
