Down-firing sub with concrete flooring?

[paulthecomputer]

I'm installing a home theater in our basement. The room is 20' x 13' with 8' ceilings. The flooring will be a floating, oak-veneer floor over concrete. The sub I am considering is the Polk DSW PRO 500. Does a down-firing sub work well on this type of flooring? Any recommendations would be appreciated.

Thanks,
Paul

I'd also like to know if I can get by in this type of room with a less expensive sub like the Infinity PS210?

If you're on a slab, get the biggest and baddest sub you can afford.

Hell, no. Your room dimensions are the exact same size as mine and I use a VMPS sub with a 15" driver and I'm about to add a couple more subs. My room is not on a slab, so you'll need even more sub than me if you truly want a great HT effect.

I can't speak to your specific speaker, but the manufacturer of my down-firing sub (HSU) reccomends putting the sub on carpeting/throw rug.

From my experiences they work great on concrete floors.

People have had good luck spiking subs also.
