jafant...I'm very familiar with the Kappa 9 and the power that they require. That won't be a problem. I still have the Pass amps.
The whole reason for this approach is to get more bass in the room to emulate the Infinity IRS Beta speakers that I have. The Betas are excellent speakers....when they are good, but can be inconsistent in the bass area on some recordings and are showing their age (31 years). The Kappa 9 are extremely consistent on all recordings. But, the Kappas are no match for the Betas in total bass output and depth (16 hz). I've entertained adding a pair of subwoofers, but I cannot get a consensus on whether or not a subwoofer will seamlessly integrate. I do know that adding more of the identical woofers and amplifiers will give seamless integration. The max I'd like to spend on a pair of subwoofers is $4k period....but, anything but perfect integration is out of the question...I just won't live with that.
