I'm joining the multi-sub approach, my IB sub does a great job but I can't get decent seat-seat flat respone in 1st row, the 2nd row is pretty decent seat-seat..
[edit] adding some good multi-sub related threads in post#1
Option 1:
Build a "helper" sub using Dayton Audio TIT400C-4 15" Titanic Mk III Subwoofer in 3.5 cu ft sealed box
(this has tight fit into the corner due to my screen and LH Main location......)
[edit]
Option 1 has evolved into 2nd and 3rd sub approach, using an 18" driver for 2nd sub and 12" driver for 3rd sub
Here is graphic of that:
Option 2: (this thread discussion point)
Build a specific room designed Triangle sub w/ Dayton Audio RSS460HO-4 18" , amp, the sub triangle box will have 24" sides x 34" face x 32" tall; give or take 5.5 cu ft internal space after braces/etc.
Question:
If a triangle sub is possible and does not "break" the laws of boxed subs, then I'm doing option 2 and this thread can become a build thread, if not then I'll continue with option 1 and I'll get flat pack from Eric H (I posted in that thread a few days ago)
Basic triangle sub image is this:
Located just as shown here ................. This will give symmetric balance to the IB 4 x 15" line array on the RH side:
.
You can see my corner bass trap triangle support, this triangle corner sub would be located just under that.
My main goal is the first row has modal issues that can't be solved via all the corner bass traps I've installed, so I'd like to smooth them more by installing a just as (almost?) capable sub on the LH side as my IB sub on RH side.
(I can't do a stereo IB sub on LH side or I would have)
It will be sticking out into the room, while the IB baffle plate on the RH side is about 4" into the room, not purely symmetric.....
1st row seats 1-4, you can see/hear the seat-seat variations..............................2nd row seats 5-8, very consistent across the seats::
.
I'm looking forward to planning and "fixing" my 1st row seats modal issues.
