Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

example

The Fostex FW305 is 1.4% efficient and 12" diameter, and could give 30Hz with a ported box, if you use an SET with a damping factor of 2-3.

To get 20% efficiency would need 14 of them. With close packing, you might make an array as small as 4 feet diameter, which is 1/4 wave at 70Hz - a reasonable maximum for the crossover. A hair more than an octave bandwidth. The box would be somewhere around 100-200 cubic feet.

A similar array of 6" 96dB drivers (there are some) could cover 70Hz to 160Hz.

I don't know any direct radiators with 96dB sensitivity and 3"diameter, so I think you would be in trouble without horns.
