bobc910 Posted September 10, 2016 Author Share Posted September 10, 2016 I am a big fan of more subwoofers. I want strong, not loud. Too many stuffs to buy so might not be able to start with more than 4. I am sure I can always add more down the road. We will be working on the interior design when we get a little closer to framing the house. Definitely no bare concrete floor and wall. It needs to look like a theater, not jail.

derrickdj1 Posted September 10, 2016 Share Posted September 10, 2016 Go DIY with the subs. More powerful and can be done for 1/3 or less the price of retail. Quote Link to comment Share on other sites More sharing options...

You loose 15-17 db. of spl sitting on carpet in a basement. You can shake a wood floor but, hard to shake all that cement. How do you come up with that number Derrick?

derrickdj1 Posted September 10, 2016 Share Posted September 10, 2016 The number is from my own expierence and from some of the work in the ULF thread on AVS. I didn't need bigger and more subs til I moved the HT from upstair to down in the basement. In the ULF thread various systems were tested on a suspended floor and also on concrete. It is much harder to get good tactile response sitting on concrete compared to a wood floor upstairs. Also, in a lot of basement, a drop ceiling is used which also acts as a bass trap. This is one of the reason for using risers for the seating in dedicated HT. Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted September 10, 2016 Share Posted September 10, 2016 Ah ok. Just was wondering if there was a math formula or something to calculate that. I know for sure about moving from wood to concrete. My ultras were the bees knees upstairs. Downstairs they were a joke. Lol. 1 Quote Link to comment Share on other sites More sharing options...
bobc910 Posted September 10, 2016 Author Share Posted September 10, 2016 More subs = wife will say I need to have my hearing check, father in law will bring his subs and add to whatever else that will go in, and won't go back home. I think the hole is getting deeper by the post...no turning back now. 1 Quote Link to comment Share on other sites More sharing options...
bobc910 Posted September 12, 2016 Author Share Posted September 12, 2016 I had a chance to listen to the KEF R700 this morning. I think my Frankenstein RF7 is superior in every way. 1 Quote Link to comment Share on other sites More sharing options...

I've read somewhere that supposedly the official explanation is that concrete doesn't actually kill the sound, but at the same time, it doesn't add to the bass. With wood and drywall, it flexes just enough to actually reinforce the sound. Concrete, you get nothing, but that doesn't mean it's soaking up bass like a sponge.

derrickdj1 Posted September 12, 2016 Share Posted September 12, 2016 For tactile response(TR) you need a surface that resonates. In our homes, concrete has the poorest resonance properties. It can help to contain the sound and also reinforce some bass in the room. Boundary gain is affected by wall, ceiling and floor construction. I will blow my system up before I piss off the neighbors.

bobc910 Posted September 13, 2016 Author Share Posted September 13, 2016 We are going with 2 rows of seats. Either row of 3 or row of 4 seats. Of course, we want to max out on the screen because L,R,C, and some subwoofers will be behind the screen. If I have room in the budget for more subwoofers, they will go on both side of the wall. Surrounds will be mounted on the wall and ceiling. Quote Link to comment Share on other sites More sharing options...
