The listening room in my new house is on the first floor and has a bouncy suspended floor. This means a lot of the bass energy is wasted driving the floor and it can also sound boomy. My present kit just doesn't work in the new room, so I have decided to splash out on a complete new system. I have had a number of demos and am always drawn to nice big speakers with powerful amps that give a sense of solidity and the feeling that the musicians are there in person. I like to be able to play the system loud when the mood takes. However, I am not sure how such a system would work in my room. I have considered a number of options: 1) using a de-coupling device under the speakers, but what would work best? 2) get some stand mounts and a sub which could be mounted off of the floor - but would it sound as good as big floormounts? 3) re-enforce the floor with some extra floor joists and fill the void with roof insulation - a tad drastic 4) move house again - even more drastic. I would be interested if any one else has had a similar problem and how they overcame it.
