Floorstanders on wood floor, help

Here's the setup:
- suspended wood floor, joists accessible from below
- jute carpet pad, very dense
- carpet, very dense/tight pile
- B&W N803's

We want to eliminate bass bloom while preserving attacks and PRAT. Here's what we've tried so far...

Nothing, flat on the carpet...
soft attacks/PRAT plus lots of bass bloom; worst of both worlds

Speakers on sorbothane footers on wood boards...
eliminated bass bloom but killed attacks/PRAT; deadly dullness

Spikes long enough to pierce carpet/pad and reach the floor...
great attacks/PRAT but enormous bass bloom; coupling to a 13 x 17 x 8 bass drum is not the right idea!

Spikes just shorter than the carpet/pad thickness, so not quite touching the wood floor...
great attacks/PRAT but still annoying bass bloom on some recordings; best we've tried so far, but could be better

Any ideas to preserve attacks and PRAT while controlling bass bloom? TIA.

Jsawhitlock,

Unfortunately, there's little I can do about speaker placement. They're centered on the TV, about 10-12" farther into the room. Any position change causes audible differences in image or soundstage. We've put a lot of listening time into getting those right.

What would better spikes do? Wouldn't they just feed *more* energy into the bass drum/floor? (Admitting my ignorance.)

Bass traps. There's an idea nobody's mentioned yet! Any suggestions for good ones?

Thanks,
Doug

Dougdeacon, Some spikes will do a better job coupling the speaker to the floor as I find brass spikes work best for both audio componets and speakers. The tube traps or Echo Busters both work great. I use the Echo Busters and Bass Busters and improved my room. The tube traps also work good. Happy Tuning!

TWL said to use Sistrum platforms. I agree and I use Sistrum Platforms under all my audio devices. Robert will have a particular one to take care of your speaker needs. Tom

A bit of a late response but the Aurios/concrete slab system has worked great for me. I have pictures and a description of and easy way to put them togther in "my system"
