Rerurn to Romy the Cat's Site

Being +/- resigned to using BR myself right now, I concur with the idea of "not using" the bin and/or port for significant gain, and especially not to push a driver down to Fs.

I don't know the driver being referred to here, but I would recommend taking another look at whether you want 650 Hz or, say, 40 Hz, because I seriously doubt you can get that sort of range with harmonic and/or dynamic continuity.  Basically, the bin/port will affect the character of the sound differently as frequency rises.

I chose to go low-ish and wound up using very thick plywood and I coated the inside of the bins with acrylic-modified stone veneer mortar as part of my efforts to get the box out of the sonic equation.  I tried using felt inside and wound up with alternate inside faces only felted.  The port came out very close to the computer simulations, but any variation is ultimately audible.


Best regards,
