My Logitech Z-2300s system had been working for 16 years before the satellite units started to crack.The sub still works perfectly and I did not want to part ways with the sub 120W of rattling power.I tried repairing the satellites, but that would not last.I measured their size and got the specs to get replacements that could work as closely as the original speakers.I selected the Visaton FRS7-8 2.5 8 Ohm Full-Range Speaker, since they closely matched the mounting holes and fit inside the satellite enclosure.The Visaton FRS7-8 2.5 8 Ohm Full-Range Speaker have very good audio quality, specially when compared to the outstanding quality of the units they were replacing.I got two units and they have the same level and tone in each range and they responded equally to the same frequencies.I ran some test from 20000Hz all the way down to 10Hz. I could clearly hear the frequency range of 17000Hz to 18Hz.There was some rattle and also humming when playing content with deep bass at high levels (above 70 volume). The humming was present even when no playing any audio or sound...it was a faint humming though.During a gaming session or voice I could not see the a difference between the Visaton FRS7-8 and the originals speakers. I could tell a difference when listening to music though.The Visaton FRS7-8 is a full range speaker with balanced frequency response and good highs. They are suitable as built-in speaker for a diy unit, monitoring speakers or a replacement for old not working units.

Using these as external speakers on a Christmas prop . The Christmas prop had a built in, tinny, 1 inch diamter speaker that did not have decent sound nor volume. Bought this and wired in in place of the original - now I have nice sound quality and great (louder) volume
