that is getting a little carried away, but mr. hurd's suggestion would certainly be a good one. i'd go with a little more amp, something around 1000 watts per channel. the behringer inuke 3000 dsp amp might be something to consider if two thx ultra 2 clones are the choice.
I don't think so. It's been said by many that a single infinity 120.9w can best pb13 untra in the rights box. This was said by a very knowledgable member about jinjuku's build:
"The potential output of one of these is so great, that it would be very similar to a PB13 Ultra, except that the PB13 would not have as much output in the lowest range, because the port on Andrew's design offers less compression due to the large cross section area, and the PB13 would potentially offer greater output by some degree, in the higher octaves, because of it's larger cone surface radiation area. But to realize the output potential of the Kappa Perfect cabinet design above, you would need to use a bridged EP2500 to deliver sufficient peak power. However, one does not need this level of capability in actual use. It's overkill. However, stereo units are always going to provide better ability to integrate with the main speakers, even if you don't need the output ability that is possible."
The tc epic 12 has more capability than the infinity 120.9w (supposed replacement for the perfect series). This is the older SVS model though. Not the new one with 1000 watt dsp.
Granted this may not be done with a pair of 500 watt plate amps but of he goes with a pro amp it could.
