Down Firing Sub Carpet

And since the shaking directly affects the floor the floor starts shaking.

Down firing sub carpet.

Although carpet will absorb some of the sound it is better to place the down fire on carpet than it is on hard smooth surfaces as these will reflect sound directly and cause a boomy listening experience that can be fairly unpleasant. After that the ceiling comes next. 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. Since the floors connect to the walls they re also going to shake.

The domino effect starts because of the shaking of the subwoofer box. 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. A down firing subwoofer box produces a domino effect if placed inside a room. Since the subwoofer is there to push deeper sounds and longer wavelengths the sound waves it s producing simply won t be affected as much as shorter wavelength sounds like those produced at the rest of the speakers in.

My family room is fairly small 15 x 12 and carpeted. Keep doing that until you have 3 4 options so you can narrow down the big winner. Put a piece of tape down on the floor when you notice things are sounding good then move to another spot. And even for a down facing subwoofer the amount of sound being absorbed by the carpet is likely going to be negligible.

You also have to leave 1 4 to 1 3 of the cones diameter for clearance other wise you will run into cancellation issues.
