I have a question. I've been looking at drivers, and something puzzles me. I look at this woofer: http://www.partsexpress.com/pe/showd...ID=16239&DID=7 and I look at the Tumult: http://www.adireaudio.com/diy_audio/...ire/tumult.htm The Peerless has about 3.5dB more efficiency at 1W than the Tumult and a lower resonance (and is smaller), while the Tumult has higher power and excursion. Shouldn't the Peerless reach lower frequencies than the Tumult? And wouldn't they play comparably loud at max power? Could someone explain to me the technical reasons why the Peerless has a higher efficiency with a lower resonance in a smaller woofer?
