Default SDX10

How high can these be run as a midwoofer? With the low inductance, and low impedance I was thinking maybe you could actively run a pair of these up to around 300hz? Or even a single in a little 3-way monitor?

Got any response graphs? Is see a bit of an impedance glitch at 900hz and 1.4...surround resonance?

They should easily reach 300... Bob & i were speculating that maybe even 1k was doable. I do need to get my 4 into boxes.

Oh man, at 1K I bet you could probably cross them to the LD25X in a 120deg waveguide! 20hz - 20khz O_O

Sensitivity would be around 80.5db which is fine for a small-room monitor.

A mini A-7 or whatever. I could go there. I have amplifiers.

there is a not so nice peak in the FR around 1500Hz, so you'll probably want to stay away a bit further than 1kHz. can't tell how much this will sound through if filtered properly

here is a measurement of a SDX10 in a (rather small) box:
