There is the new buttkicker II. It is smaller, more powerful, more efficient, and cheaper! This one will fit in a 2x6 while the other required a 2x8

Thanks Stacey. I'll have to give Marvin a call on Monday. This may be the time to purchase 4 new ones to replace the other 2 buttkickers. Headroom is nice to have on any device that pushes the extremes on occasion. I'll probably stack two on the left side of the plaform and two on the right (side by side) and in stereo. I wonder if they are shipping yet?

They are probably still 4 ohm loads, so it might be tough to get the bridged 2000 watt mono to drive a 2 ohm load properly. In general, I am anxious to discuss the physics with him. The Crown K2 amps are still the best way to go IMO, as they are fanless. I'll probably sell the Carvin's and grab a couple K2 amps. I need to look into the QSC Audio amps first to make a decision.

For those who don't know, Eminence Speaker Corp is the OEM for the Buttkicker.

Check out both the Crown K2 as well as this amp manufacturer for alternatives to the Carvin amps.

On a further note, I'm a little weary about the new one. I was just thinking about what you just said. Physics dictates that the decrease in size and increase in efficiency may indeed change the resonance frequency. You don't get something for nothing. Hoffman's Iron law for subwoofers applies to tactile transducers. Something tells me that since the efficiency is increased and they are smaller, they probably have a much higher resonance frequency. This means they might have traded off some deep bass extension capability. I am not going to be quick to jump just yet. The smaller size itself is inconsequential and not of benefit to me. I will probably make my next platform in the future closer to 12 inches high instead of the current 9.5 inches in height.

Sony should have not used half-rate DTS. glad they bumped DD up to 448kbps. They should have used full rate DTS with a DD 2.0 track or no DTS at all. That's my opinion of course. I don't believe that they would have had less video headroom using DTS at 1.4 mbps simply because All my sources said the original Fifth used 5 Mbps video at peak rate. Using full rate DTS should still allow them to increase the peak video bit rate to 8.0 Mbps. In any case, since they are not using full rate DTS, I would have preferred just a 448 DD track assuming they can get the mix flags correct. Warner can't seem to get a clue these days. It doesn't suprize me that Warner DVDs don't use the proper mix flags. In any case, Superbit DVDs are an improvement and hopefully we can see more such DVDs.

Wonder how the 800 will handle seamless layer change? Nothing a software update can't handle in the worst case scenerio.
