    I have a Peavey Max 700 and 410TVX, and I'm thinking about getting a Dr. Bass Rx212 and Rx210 to replace the 410. it's just too heavy. however, I don't plan to use the Max 700 forever, so I thought it would be wise to get the Dr. Bass cabs in 8 ohms, and for a while I'll only have the 212, so what I'm wondering is this:

    In theory, which of these would be louder? 475 watts through a 410 with 97 db sensitivity (4 ohm peavey cab), or 275 watts through a 212 with 103 db sensitivity (8 ohm dr. bass).

    I'm sure there's more to it than that, but I have no way of trying Dr. Bass so this estimate is the best i can do :)

    Well, if I'm doing the math correctly....

    Peavey 97 dB + 10 log (474) dB = 124 dB

    Dr. Bass 103 dB + 10 log (274) dB = 127 dB

    Keep in mind that sensitivities are usually measured at 1 KHz.

    Again, assuming that I did the math right, it really goes to show the loudness advantage of having an efficient cabinet.
