I absolutely agree! When the train goes off the tracks in that scene from Polar Express my entire living room shakes including the floor. Everyone watching loves that part! But the floor shakes...

I'd expect most rattles to be excited by sound waves in the air, though I suppose it can happen from structure vibration. So yeah, I agree with that, though rattles are a different issue than what I...

Openings are good, but I'll guess you don't have any bass traps? It's too bad all your corners are walled off at an angle because normal 90 degree corners are the best place for traps. That said, the...

Symmetry matters, but not so much at bass frequencies. So yeah, having three bass traps in the corners is vastly better than none. Also, rectangle rooms have 12 corners, not just four where walls...

You really need to hire an independent professional. If there's no absorption or diffusion at all, something will probably be needed. But dead zones are also caused by improper loudspeaker aiming,...

What matters most is getting the treatment in the right places. How you hang it is not usually important. I can't imagine the chains will be a problem.

No, sorry, you're still wrong. Tuned bass traps are basically an L/C filter so they have a single center frequency whether used indoors or outdoors. As for construction details, they're right here on...

Yes, this is exactly what you want, though you need more bass traps and other treatment in other parts of the room. Wood panel (diaphragm) bass traps are useful, but not in a room like yours....

Yes, in your receiver set the five speakers to small if you have a subwoofer. And 80 Hz is the standard crossover frequency.

LOL, then you'll have to look for another test that used separate tweeters to avoid IM Distortion. Or maybe as a "good doc" you can test this yourself?
