No you read that correctly.
Ive had 3 of the XXX12D2's.
They flex a MASSIVE amount.
by the way o/p, XXX woofers are SQL not SPL
Ty sir, did not know that. I feel like the sub gets loud but only on certain songs. Coulda been the way I made the box too though
it does get very loud especially for an SQL speaker
From my experience with them, the 12's like ~4^3ft before displacement, and need at least a 4" wide port to breathe properly.
My box was tuned to 32.9hz, at loved frequencies in the range of 25-40hz, but would redoing to 70hz and less.
goodluck with yours
I blew my last XXX out this afternoon, and am now woofer-less :'(
Let me know if you need any more info on the XXX series
