Summary: These do not stack up what so ever to the previous z-2300 system in any way. The bass is weak compared to the older 8 inch sub and the speakers don't make you def like the old ones did. Not only that both of my subs now have a terrible rattle at low volume and I have only had them for two months and rarely mad them bump. I would suggest you look elsewhere for a good 2.1 or try to find the old z-2300 system they used to make.
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: 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.
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.
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...
Summary: The Logitech Z-2300 were a decent pair of speakers. A few friend had them and I was enthused when they played them. Also they were made at a time where it's said that fitting the most quality into this range of computer speakers was the goal of many manufacturers (*Klipsch ProMedia 2.0, from said time period, still selling*) Logitech has and ugly side we all know too well.
Pros: They play sound, and hook up through everyday common connectors!
Summary: I've had my 2200s for nearly 8 years & they will kick these 623s to the curb and back. I had a set of Klipsch ProMedia 2.1 & enjoyed them immensely...until the sub went out. I bought a set of these figuring to maintain the quality of sound I experienced with the Z2200s. I was wrong. My 2200s are attached to a 50" TV in the family room & impress everyone.
Excerpt: Sounded Great when I first hooked them up. My wife was listening to Pandora on about the third week after getting them and they suddenly stopped working and started making a clicking sound with the power going on and off. Of course I threw the box out so I could not send it back to B&H. I contacted Logitech and got customer service from India via the internet and after trying the stuff they said to do.
Summary: I tried these and was not impressed by them at all.. I exchanged them for the Klipsh ProMedia 2.1 Computer Speakers and the Klipsh blow these Logitech out of the water for sound, bass , crispness, and performance, I am so glad I made the change..
