How low could you expect 2 M-165X's to go in a 1-1.2 cubic ft sealed enclosure? They will be powered by a 100 watt (@8 ohms) plate amp, wired in series and only driven from 200 hz and down. How would they compare to a single M-165X in a 1.2 cubic ft ported enclosure powered by the same amp?
Thanks,
