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...

Raj,

At some frequencies...
