How big is your listening space bob? |
Around 7000 ft^3 now. It is a full basement room. I knew I needed something extreme to try to fill it with decent SPL. That is why I went with the 15" Tumult plus two 18" PRs. I drive it with a Mackie M1400 pro amp that gives 1400 watts bridged into 4 ohms. Got up to 110 dB SPL using a 30 Hz sine before the circuit feeding the Mackie popped.
The nice thing about the Tumult is its very low distortion of 2% @ 13Hz 102 dB SPL as measured with this:
Just a bit of a SWAG looking at the second and third harmonics and the table in the TrueRTA help file.
