Used on major roads: excellent performance of 15 "
Frank and precise bass.

edit: I use it now on a 2-way (fc = 1600Hz) very well in the medium as well.
Truly a joy these amps!

Edit 07-07-2008: It is now spent on passive fullrange stereo filtered. The quality is impeccable. The speakers are low yield him no fear.
A serious and well run now, above is completely convincing as well.
Change? He must never be rinsed really make me look elsewhere.
