@soundrealaudioI i can explain my philosophy which i used before
with Bache Audio -002
You have 8 watt tube power. Ok , No more, you have to use this Revenue 8 to power midrange and tweeter. No more power to get
good sound , just 8 watts, From 700hz and up to 20000, you need
high sensitivity wideband driver and tweeter. External subwoofer
does not good in this situation . you need extra midwoofer 5-6" but you
cannot find midbass with sensitivity more 90db. So we used active buld
in small amps with crossover point 700hz. But dont worry , is not important , it will be driven just midbass, it not will be affected to tube sound
