Rodman99999, I'll take you up on your bet. My house up against your farm. Here goes:
The speakers used were 92 dB efficient two-ways.
The woofer in the RMAF '06 room had a moving mass of 79 grams; Fs = 40 Hz; Qes = .35; Qms = 11.69, and Vas = 77 liters.
The speaker in the RMAF '07 room had two woofers, each with a moving mass of 41 grams [combined moving mass of 82 grams]; Fs = 31 Hz; Qes = .32; Qms = 4.35; and Vas = 121 liters [combined Vas of 242 liters]. This speaker is a bipolar, so the efficiency is 3 dB lower than the combined T/S parameters would indicate.
I am the speaker designer (thanks for asking!). The amplifier was an Atma-Sphere S-30.
So tell me.... just where is my new farm located??
;o)
