Any thoughts on what could reduce this without a huge cost? Blu-tack? Different securing to the wall? Styrofoam between the studs?

I live in a condo with neighbors downstairs. My EP500 made the walls and windows rattle and I wanted to tone it down a bit. So I ordered a GRAMMA pad from

I still get bass, but the rattling has stopped. It's not that expensive so you could give it a try (and quite frankly, you can probably go the DIY route).

When I was in high school, I made an isolator that worked very well for my turntable. I've wondered how well a larger version would work for a sub.

Basically, I made a nice-looking wooden "pan" (say, 16"W x 16"D x 2"H) and filled it with sand. I placed a "floating" panel on top of the sand (For the example above, it would be maybe 15.5" x 15.5") and sat my turntable on top of that.

So, the TT was very well isolated from rumble as it was essentially sitting on 2" of sand and not touching anything else.

It's certainly quicker and easier to order a GRAMMA pad, but I've always wondered if my little device idea would work for a sub. smile

Sorry your fledgling teenage company didn't pan out. I woulda bought a Johnson Isolator, had I been aware. Maybe it was the name?
Always call the place you live a house. When you're old, everyone else will call it a home.
