I am trying to get more bottom-end chest thumping fun from my Yamaha
DTXtremeII electronic drums - what I have available to use at the mo is:

dB Technologies Opera 212 active cab
Ohm Technologies 18" 4R driver (700W)
Yamaha P2500S power amp (1300W to 4R bridged)

What I'm thinking of is:

1) Active crossover to split signal between Opera 212 (high) & Yamaha P2500S
(low)
2) build/buy 2nd hand cab to mount the driver to run off the P2500S

Will I need any circuitry to use the driver or will I be fine just to stick
a speakon in the wall of the cab?

Any other useful thoughts welcome.

Thanks
Eddie
