Is having a front firing, bottom ported subwoofer (energy S10.3) directly on a laminate covered cement slab floor ok?

Displays are like 100% cotton t-shirts. Always buy a size larger than you think you'll need, as they tend to shrink over time.

It's fine, assuming it has rubber feet. But one of the advantages of down firing, be it a port or the driver, is the acoustic filtering of above bandwidth harmonics, which is greatly improved if there's carpet beneath the sub. For that matter carpet throughout the room will give a much better result than bare laminate.

It's a front firing sub, with downward facing ports. Sub has wooden feet, but I will add rubber isolation pads. Carpeting the room is not an option, but there is a large throw rug in the room, and I'll also add a small piece of rug (2x2) under the sub if that will be helpful.

And how right you are Bill. I bought an indoor/outdoor rubber backed Berber type mat, trimmed it to size, and what a difference it makes tightening up the bass. The rubber feet I ordered will arrive Monday, and I'll attach them to the wooden legs as well.

Thanks again for your assistance.
