Oh I've been here the whole time. This time, trying to push some amps under load without the noise. Just another one of my craaaaaaazy ideas like the open chamber Frankenlab. BTW Art, at the '07 NYC shootout, if I did wire the drivers in parallel instead of series that would be +6db, wouldn't it?

Raj,
Space heaters don’t make much noise, make good amp test loads, and cost a lot less than speaker recones.
A cabinet wired in series (12 ohms nominal) rather than parallel (three ohms nominal) would receive 6 dB less power assuming the amp was putting out the same voltage into each load.
From what I hear, a standard Lab Sub is more in the 4 Ohm range, wired in series it would be 8 ohms.
I'd guess the Frankenlab would probably be closer to the nominal ratings, 3 or 12 ohm. 12 compared to 4 Ohm would be a bit less than a 6 dB difference.
At some frequencies...
