Terrible Booms

Hi everyone, I'm sad because I really tried everything (marble base, Gaia isoacoustic, anti-seismic bases, etc.)) but my speakers (ProAc D40R) in my environment (suspended parquet - with voids below) creates terrible booms . I managed to get a good compromise (tube traps and panels) but it's not as I would like. Maybe I should take small speakers, or in a closed box. The fact is that I like my speakers and I don't feel like changing them.
