Adding damping material in subs
« on: May 30, 2019, 11:36:37 am »

A friend has 4 VRX918SP subs that we use for smaller jobs. I've always liked the sound and output these little subs can achieve. But often seemed a little boomy. We opened one up and discovered just a small piece of damping material. So we decided to add some of our own and see what happens.

Made a trip to Lowes and picked up some rock wool batting. We cut it to fit and secured it all around the inside of the cabinet using a pneumatic stapler and some round cardboard backers. Making sure we didn't cover up any electronics or amps and their ability to dissipate heat. 

Wow, what a difference. Really tightened up the low end and made them much more solid. It really helped.

I mentioned what we did to another friend who has several SRX828 subs and we did the same thing. Big difference as well.

Worked well for us. Just thought I would pass along our experience.
