You didnt mention what kind of floor your sub is on but in my room, on a suspended hardwood floor, I found that decoupling with Sorbothane half sphere footers was a huge improvement. Also adding weight on top of my Sub (REL T/7X) in terms of a 15lb slab of marble with thick felt between them seemed to help too. Faster, tighter, cleaner.
Subwoofer tweaks
Hi,
I have a Velodyne DD-10 and a friend recently let me borrow
a pair of brass spikes to try. I stuck them under the sub
and noticed an improvement. The sub sounded cleaner and
had better definition. I was wondering if anyone has
tried any other products (Aurios,cones, etc) that have made
an appreciable change (for the better I hope) on their sub.
Thanks
