Does sub cabinet weight affect low end response?

(1/1)

bvdd:
I build Thiele design 15" cabinets using 3/4 plywood for subs which work great for what I do.

I use the same model 8 ohm speakers and all dimensions both inside and out are identical.

On stage, I use two cabinets crossed over at 100hz, powered by a Crown XLS 1502 in bridge mode - 1500w @ 4 ohms.

I've noticed that some 3/4 plywood weighs noticeably more than others.

Would the lighter vs. heavier plywood weight difference affect the bass response and perceived volume of the cabinet?

If so, how much of a weight difference before I notice?

Thanks.
