SVT-sized 8x10" cab with Gamma 10's?

    I just got 8 Eminence Gamma 10"'s. I was wondering if any of the cabinet gurus out there knew if those would be appropriate for the original SVT-sized 810 cabinet design (sealed). I know that the Gamma's are 300w each, but the power will be matched.
  2. The Gamma 10 has an EBP of 117, and is best suited for vented boxes. Optimum sealed box drivers have an EBP around 50.

    That noted, the Gamma requires a sealed B2 (Qts=0.707) volume of 1.4 cubic feet each, or D2 (Qts=0.577) volume of 4.6 cubic feet each.

    Stuffing the Gamma into a smaller volume raises the Qts sharply. In a 1.0 cubic foot (net), the Qts is 0.773, Fb=95, F3=88 Hz. This will give a very strong mid-bass hump, which may or may not be desireable. Bass rolls off at 12dB per octave below 95 Hz.

    This driver has a very short Xmax, but a long Xmech. This means it will be easily driven into distortion, but will take a lot of excursion before damage. Again, this may or may not be what you want for tone.
