Best way to "foot" a subwoofer ??

Kgveteran;

Yep, (2) of the walls are concrete, regrettably, I located my listening room in my basment for maximum "isolation", (3 kids, one patience-running-thin wife)but as "Snickelfritz" --(thanks!) so accurately points out (and as I again, regrettably found out) a concrete floor just doesn't assist the bass in any way.

Boy do I miss my "old" set up (former dwelling) with a good old fashioned "floating floor".

It's this apparent lack of bass-impact that drove me to purchase a sub.in the first place.

Same speaker, new "concrete floor" room, and it's like someone cut the bass balls off my speakers!

Thanks guys for your input. I'll just have to keep experimenting.

Have you thought about a riser ? You could build one out of 2x4's and use OSB(oriented strand board) tongue and groove.Use a ton of liquid nail and screw the hell out of it with drywall screws.Wa-la,floating floor again.Thats how the big boys do it.Get some 2'x4'(4-5 inches thick should do)sheets of owens corning 703 board and cover it with some real porus fabric and kill those first reflections.Build a bunch of RPG skylines to diffuse the rest of the flat surface and you are on your way.Read,read,read.That room can work if you work on that room.

Kgveteran is essentially suggesting that you construct large bass traps over your concrete floor.
(a flexible, insulated wall or floor works much like a bass trap)
It's an excellent suggestion, if your room can accommodate it.

Here's a link to instructions and theory for building effective room-sized bass traps for very little cost.
