In Reply to: Ideal Parameters for OB Woofer posted by Joseph Cohen on February 3, 2007 at 12:28:05:
Hi Folks,I've been following this thread with interest, for I'm pondering an OB setup myself.
I'm wondering about bass extension. Using Thorsten Loesch's Xlbaffle spreadsheet, and plugging in the Dayton 295-455 (15", Qts 0.65, Fs 20.8Hz) in a 40" baffle, I get +-1.5dB from 1000Hz to 30Hz, down 6dB at 20Hz, before equalization.
Comments? Is that believable? Am I overlooking something? That looks like fine bass response to me, but I've been wrong before.
As an aside, though "high efficiency open baffle bass" may be an oxmoron, it may still be a good match to a high efficiency OB mid-high setup. I'm pondering combining somthing like the Fostex FX120 open baffle with a 300B SET for say 200Hz up, and the Dayton open baffle with whatever sand boatanchor I can find for below 200Hz.
Thanks for any insights!
