Isobaric will increase moving mass and motor, but I'm not sure Beta 15's are the kind of speaker you'd want to run that way.

Should play fairly loud, but the box peaks nearly 5db at 62 hz.

I don't know what they cost, but I imagine you could get a single Kappa 15lf for the price of two of the betas. Run it five cubes (140 litres) tuned to 40 Hz with a pair of 4" ports. You'll get great output, and this thing goes damn *low* all things considering... To me it sounds flat to 30 Hz almost. It's one of the best low frequency drivers I have found from eminence that isn't too pricey and will run in a pretty small box.

You'll get more output than the betas (same sensitivity, but no power compression) with flat response, good sound and surprisingly deep bass.

Trouble is that I have a pair of bet 15's sitting on the shelf, just trying to figure how to use them best ! Thanks for the suggestion though :-))

Oh ok, I kinda figured that.

Things will be a bit better if you use a larger box... Like at least 5-6 cuft.
