Why not horns?

Prez, so one watt to the basshorns produces 109dB at one meter?

Identical in every way expect the fact that the monobloc has paralleled outputs.

Identical except it has more power and a different output impedance and just about everyone who has tried it says running a stereo amp in mono changes it's sound even if they are played to the same level.

BTW, If you take a 75W amp and run it as a monoblock you get twice the voltage swing so 4 times the power, not twice. What amps were these?

Wes, that is what Dan told us, I was asking him to clarify if that was what he meant.

I believe the presenter in the Cathedral room (the designer of the speakers I believe) told me it was a vintage Fisher tube amp of some sort, but it was tucked away and I did not see it.

The source was digital, a Marantz player or something along those lines, but not certain.

I wish you could edit,

Prez, you said the outputs of the amp were parallel to double the power. It doesn't work that way. Please clarify.

Herman ,

That would be bridged for 4 times the power and not necessarily just because it is a monobloc.

What frequency are they rating the bass driver @ 1 K, 100 hz?

Wes, I know nothing about this bass driver. You need to ask Dan.

I understand what bridging an amp is. If you bridge a 75W amp you get 300 watts if the power supply can handle it, not the 150 stated by paralleling it, whatever that means. Perhaps I misunderstood what he meant, that's why I asked him to clarify.
