If enough room, would experiment with pulling out from wall more. You can place a rubber Welcome floor mat to try under a speaker also to try out. 1 Quote Link to comment Share on other sites More sharing options...

billybob Posted January 5, 2021 Share Posted January 5, 2021 There is also material like rubber foam material to place on wall down by the port holes. Bass Traps used for reflection. Yes experiment and read up... Quote Link to comment Share on other sites More sharing options...
PICHON Posted January 12, 2021 Author Share Posted January 12, 2021 Hi! A review of my progress. So: 1/ transition to bi amplification... very noticeable change of the bass, much more pechu and more presence. 2/ decoupling of the speakers. I put a polystyrene slab and on top a concrete/slate slab about 30kg and the speakers on spikes placed on it. the again it is a flawless! Really cash of this musical progression! 1 Quote Link to comment Share on other sites More sharing options...

billybob Posted January 12, 2021 Share Posted January 12, 2021 Guess you have less vibration? Did your decoupling idea work? Quote Link to comment Share on other sites More sharing options...
PICHON Posted January 12, 2021 Author Share Posted January 12, 2021 Just now, billybob said: Vous avez moins de vibrations? Votre idée de découplage a-t-elle fonctionné? Yes, it brought down the vibrations on the ground, clearly. on the other hand no change in the level of the wall... the hanging pictures vibrate, even the projection canvas... 1 Quote Link to comment Share on other sites More sharing options...
PICHON Posted January 12, 2021 Author Share Posted January 12, 2021 I am thinking of putting armrests (absorbent) on the back of the enclosures Quote Link to comment Share on other sites More sharing options...

I see your rear of speaker ports are out a foot from the wall behind. Should be far enough for good bass. Let us know please.
