Down Firing Car Sub Into Carpet

Scott wilkinson and chris boylan have an answer.

Down firing car sub into carpet.

I m really just looking for confirmation that my assumptions are correct. My family room is fairly small 15 x 12 and carpeted. Of course every install is different but i would have to question the benefit of down firing when used in a car trunk setup. 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. A down firing subwoofer box produces a domino effect if placed inside a room. 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. Find out in this video. 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. 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. The floor is carpet on carpet pad on cement foundation. And since the shaking directly affects the floor the floor starts shaking. After that the ceiling comes next.

Today in the irc chatroom ericduckman wants to know if putting his down firing subwoofer on carpet is going impede the quality of sound. 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.
