I'm about to build my baffle wall. And to be honest, I don't know the best position for these subs.
As you guys know more about subwoofers than I do. I thought I would ask for a "gut" feel on this, because i can't position, measure and then re-position as required.
They were purchase via this thread (500 w x 780 l x 170d sealed) :-
The spec for the speakers are :-
The LCR are JBL 3677's with L & R slightly toed inwards. The baffle wall will prob. be constructed :-
2:35 AT Screen 3.2m x 1.4m
Room 3.6m x 4.9m ( will be treated ).
Baffle Wall Construction :-
Ply ( 9mm min )
2.5mm Techsound
12.5mm Plasterboard ( Blue stuff )
20-30mm diffusion / absorption to resolve issues with sound bouncing back of AT screen.
So, my questions are (answer as few as you like):-
1. Position A or B or C.
2. At they are 1 Ohm speakers, run them all together ( so 4 Ohm ) or as two sets of 2 Ohm. ( A Trinnov 16 will be controlling them ).
3. How much power (amp) do I need ?
I do have some other subs ( to be placed at rear of the room ) that will go down to 22hz. I don't want any lower ( ATM ).
