Researching... Heavy bass effects on rest of house?
 
Has anyone with a bass heavy setup noticed cracks/joint cracks in wall components joints like moldings, crown, and wainscoting outside of their theatre?

  • Our old house was a new built on shale, after year 7 we had to re-caulk most of our baseboards and crown.
  • Our new house is now 4 years old, built in clay, and has a humidifier for winter dryness. Has very little trim issues so far.
  • I want to start adding white multi layer crown, wainscoting, and possibly some built ins in the living room over the theatre.
  • I don't see myself pushing more than a 100-110db peak under 100HZ range.
Would my theatre usage cause issues with trim joints in the rest of the house? I really don't want to re-caulk 1/2 my house every few years, is it possible to alleviate potential issues in the planning phase?


Thanks,
Robb

Bad caulk and a bad caulking job coupled with expansion and contraction of all the other building materials can result in the need to re-caulk after a few years in a new house without a theater. Depending on your theater power it may contribute to the situation.

you would be wise to let the building materials for this job acclimate to the temperature and humidity of your house before cutting and assembling. Who knows where they were stored.

So should I go with a 40-50 year caulk like in the theatre itself for the trim?


Acclimation makes sense.


thank you!

You may not remember but many years ago there was a gentleman who was into building sub-woofers for the apparent sole purpose of making his house/car shake. He posted many videos of his results and was cheered on by this crowd who also offered caution. He actually put support columns in the middle of some of his rooms to deal with the ceiling movement. He cut holes in doors and used them as sub-woofer baffles. One day his ex-wife (living separately) came on to the forum and informed us that his battle with mental illness had resulted in him taking his own life. She thanked us for the comradery and friendship offered by the strangers on the forum as it made him happy. I don't think there was any caulk left in his house.

Caulk that remains permanently flexible is always a good idea.

Comradery is always good, awful to hear though. Who was it?


Our neighbor has a huge professional mower that shakes our light fixtures as he rips past our house from 25ft away. I will not be playing to that level, but do want enough subs to cover any listening position nulls within the room.


Prior to last weekend, I would have said we will not need >90db in the <100hz range, but I checked out my phone audio tool at frozen II last weekend and it measured peaks at 110db in the 60-100hz range. It was a bit too much for our liking for that type of movie, but I could see wanting that volume on an action flick. I just purchased the woofers for a BOSS platform, so hopefully that will be enough of an experience to keep the actual volume <90db in all frequencies within the theatre.


thanks again for all your help Big!
