Go active, young man ... :-))

If it's significantly cheaper to get hold of a second Magnum M-120 (or even a second amp of any decent kind) than upgrade to an M-150, why don'tcha go active? :-))

When you say you'd like to listen "louder", IMO you are seeking one of two things ... or possibly both :-)) :
1. You want the dB level entering your ears to be higher, or
2. You want to experience a more "dynamic" (read "snappier") presentation.

Removing the passive crossover components and connecting amps directly to the drivers (with an active crossover before the amps) results in a more dynamic presentation because the coils and caps are no longer "in the way" and so the amps can exert a tighter control on the drivers.

Also, because each amp is only being used for part of the frequency spectrum, it can "give its all" to those frequencies ... thus you can turn up the volume because the amp has more headroom within its allocated frequency band, compared to one amp doing full-range duty.

The "rule of thumb" for actives is that 2 x 120wpc amps in a 2-way active setup is equivalent to a single 480wpc amp in a passive setup.

I think the crossover in the 1.6s happens at about 800Hz? In which case, the amp driving the quasi-ribbon would only need to be about 3/4 the power of the amp driving the bass panel (however, they both need to have the same gain, or a sound-level mismatch will occur between the two frequency bands).

Andy
