RE: fool's bi-amp ?

Posted by b.l.zeebub on February 25, 2012 at 04:44:57:
It is foolish as long as you leave the passive xovers series inductor in the circuit as it makes a complete mockery of the bass amps DF (read: control) and passives still produce around 3dB or more of insertion loss.

There is nothing stopping you from using any type of amp fully active and since active xovers usually have gain control it is a lot easier to match amps. No L-pads needed anywhere.

Also a good active xover is a fair bit cheaper than a passive using boutique components.
In my case the saving was easily enough to pay for the extra amp(s).
