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.

Aurios under the speakers! I like to use a set of 4, not 3, under each for stability with speakers. You will need some type of boards (mdf), concrete, marble, or tile under the aurios, between them and the carpet, to maintain a hard and level surfaces. The aurios will tighten the bass bloom (or "boominess", as I prefer to call it) and will also improve staging, imaging, and PRAT!
