no, by changing to sub tuned box, and sound deadening as well. I also changed the amp up a bit, and repositioned the box in a better spot.

What is sub tuned box? 18dBs, damn I wish.

Might need to post along with everything else if you're SPL is strictly SPL or daily driver.

For true SPL set ups, most everybody is tuned to low. IE in the 30's. For pure SPL you want to tune way higher, IE in the 60's.

Just a thought.
