Subs in basement, concrete under carpet?? (1 Viewer)

[Kevin Beck]

I know I have seen some info on this, but have forgotten the rules. Room is in the basement,..carpet and pad over concrete. What have you all decided to be the best way to suport your subs? Spikes throught the carpet and pad, down to the concrete? Or,...set a slab of stone on top of the carpet, and then spikes on top of that?
What is the effects of setting the sub on the carpet, vs down to the concrete, or the slab of stone? I have really lost track of this.
Thanks,..>>>--->

hi, is your sub fowarding or downward firing ???????

Spiked to the concrete. Since it's a concrete floor, carpet and padding should be ~transparent to any frequencies < ~125Hz, so driver orientation isn't an issue for an 80Hz XO sub IMO.

Thanks in advance for any info,..But I have a dual Tempest Sono,...one driver on top, and one driver on the bottom. It really seems to be lacking in output,..I know something is up with the set up, just have to find it,....

What's the point of spiking?

 

[Pete Mazz]

If a dual Tempest lacks output, I'd say something is definitely wrong.

Give us the particulars. Size, wiring, alignment, tuning...

They're used to damp the sub by acting as a high impedance mismatch between it and the massive floor.
