Keeping standmount speakers steady

[paulf-2007]

In my listening room in my barn I France, I shuttered a box under the suspended floor and filled with concrete. Speakers sit directly on the concrete covered with carpet tiles. Could be done under a wood floor

If you are putting stands directly in floor and floor is not overly wobbly, then one solution I have found is to replace the m6 or m8 spikes of the speaker stand with swivelling and tilt feet. Due to ball socket mount, they adapt to unevenness on floor. Then blu-tack speakers to stands.

To help damp a flexing floor, I have sometimes used granite slabs with discs of some manner (even coins) at each corner so that slab is free from floor. Then put speaker stands on slabs using thread on spikes or pucks to level. This will only work if floor boards or joists are not actually loose or broken.

If your wooden floor is suspended, and stands have threads - presumably M6 or M8 - replace spikes with threaded feet - I got mine from Malvern Audio on ebay - and then buy discs of Sorbothane ensuring you choose the requisite Duro and place under feet. Don't use Blutak between stand and speaker. You will be amazed at the improvements - bass will be articulate and midrange beautiful.

think they prefer 18" open type stands.. if stands are not sitting correctly on floor then maybe fit some granite or wood plinths for them(stands) to sit on

Yes heavy 3 inch thick granite or slate plinths, one piece best, larger than foot print of stand, with cones underneath resting into the tops of large cross head screws, screwed into the floor. I had a similar problem years ago and that cured it and sorted out the bass issues a crap floor can bring.

That is one way of solving the problem, if its a down stairs room.

If the floor is flexing so much that speaker stands are not stable even when waited down then you need a good carpenter to repair the floor.

It's so simple even a shit carpenter could fix it
