Thank you for posting this very informative comparison. Just reinforces my take that looks do not equate to sound. The metalic cone of the F12 has never impressed me. Things like that are usually only gimmics to suck in the gullible. Same with the copper looking drivers of the BIC Acoustec line. Give me the DV series any day since they don't try to fool people with looks. They only give the best performance/cost ratio.BTW, in your opinion, which sub sounds better?
