Noisey floors
I recently chucked a couple of big concrete slabs under my speakers.
I’d tried this in the past in homes in which my listening room’s floor was a suspended one, and noticed a difference. May even have done it here in the past, but for some reason, not in recent years with recent incarnations of the system.
I had to use pretty large slabs (600mm square) to accommodate the large speakers. Must weigh over 30 kilos each, so big buggers to haul about.
Made a significant difference to what the bass does to my ears and liver.
First of all there’s a bit less of it overall, but what there is of it is better. I assume this is due to the inert mass of the slabs hindering vibrations from the speaker from exciting the wooden suspended floorboards and air in the cavity under the wooden floor.
I’m guessing that the size of the slabs means that they are sitting over at least two floor joists. The speakers certainly feel pretty rigid.
Regarding how much overall bass energy is absent, I’ve trimmed back the squaker and tweeter by around 3dB to bring things back into balance. Things sound really good. As I say, the quality of the bass is significantly improved, as is the overall cleanliness of the system’s sound.
Really happy for a fiver per slab.
And, I managed to remember safe lifting and handling techniques. So for once my back isn’t in tatters.

I've wondered about doing that in my place as the floors are pretty bouncy.
So the spikes sat in the crosshairs of the screw quartet? (Maybe nails would’ve been more “Jesus”.)
I've just made the mistake of trying it out before properly practising...I Missed...
