Down Firing Car Sub Into Carpet

My family room is fairly small 15 x 12 and carpeted.

Down firing car sub into carpet.

I m really just looking for confirmation that my assumptions are correct. Somewhat like metanium above i have had very positive results using a woofer down firing in my car but that s because i have no trunk. Thanks for any help. My assumption is that in that case i should specifically avoid a down firing subwoofer because the floor would just absorb the sound.

How do you get perfect carpet seams when wrapping a subwoofer box with carpet. The domino effect starts because of the shaking of the subwoofer box. Since the floors connect to the walls they re also going to shake. You also have to leave 1 4 to 1 3 of the cones diameter for clearance other wise you will run into cancellation issues.

I have recently built a center console for a f 350 with 4 8 focal utopia be subs firing down with slot ports firing forward into the dash. This trick works not only for wrapping a sub enclosure. Of course every install is different but i would have to question the benefit of down firing when used in a car trunk setup. Scott wilkinson and chris boylan have an answer.

Today in the irc chatroom ericduckman wants to know if putting his down firing subwoofer on carpet is going impede the quality of sound. I just ordered a pswi 225 down firing wireless sub. And since the shaking directly affects the floor the floor starts shaking. Is it worth the time to cut out a small 13 x 13 piece of plywood to sit the subwoofer on to increase bass rather than just have it sitting directly on the carpet.

The advantages i saw to down firing was getting the woofer away from my ear the cone was about 15 away when it was direct firing. A down firing subwoofer box produces a domino effect if placed inside a room.
