I have carpet and underlay over a timber floor and for many years had my speakers on quite large spikes to cut through to the timber.
I though it sounded ok but when I bought new speakers last year the speaker manufacturer recommended I decouple the speakers from the floor by placing a slab of granite on top of the carpet and the speakers on the slabs. I had never realised how bad the bass had been or how much it had muddied the midrange.
It’s really easy to try. I initially just used a large clay paver from the garden and the improvement was instant. Granite does look better. Two of my audio buddies were equally impressed and have done the same with similar results.
