Room Acoustics

As one trying to manage my room acoustics, learning it is an art which is not always intuitive or consistent, I found this article interesting.

Tightened bass usually means that you are now hearing vibrational harmonics from cabinet/floor resonances which tend to add "edge" to the sound far above the bass. Also, bass travels faster through the floor than through the air so additional coupling of the speaker to the floor may also add a sense of physical punch as an initial bass transient. The stone plate atop the carpet may be acting in similar ways. I have long eschewed spiking speakers to the floor for these reasons, preferring soft mounts which "float" the speakers atop the carpet. The same goes for speaker/stand interfaces with stand-mounted speakers. Softer mounts sound better overall, to my ears.

Presumably you had used spikes that pierce the carpet before introducing the slab. What floor construction is the carpet laid on?

I think I'd consider this:

1. Fix spikes to the underside of the stone slab so it is well grounded onto the floor - particularly if timber on concrete or other solid base
2. Fit IsoAcoustic Gaia isolation feet to your speakers.

I found that Gaias onto my solid floor improved the bass considerably - it was more detailed and with greater clarity. Instruments could much more easily be identified. One could add Gaia Carpet Discs in place of the stone slab, though this would appear to rather defeat the object, so keeping the slab to provide a firm base makes sense.

Agree with above posters that Gaias, or, as in my case, Townshend Podiums, are ideal for decoupling speakers from the room and provide instant benefits.
