I am building a new home that will have a dedicated Home Theatre room and I am now about to start working with suppliers to find a suitable wall/ceiling construction to minimise sound leakage to other rooms. I’d like to know the approximate SPL (dB) that my system could create in the room to get an idea of effectiveness of the walls (most quote a sound reduction in dB).
The room will be 6000 x 4500 x 2250mm (20 x 15 x 7ft) with the following gear:
MOSFET 180W per channel for JBL 4344 MF & HF (2122H, 2425J & 2405)
Crown K1 350W per channel for JBL 4344 LF (2235H)
Crown K2 800W per channel for pair of Sub1500
MOSFET 110W per channel for JBL Control 5 (Rears)
MOSFET 110W per channel for JBL Control 5 (Sides)
I know it is near on impossible to calculate but I was wondering if anyone could give a rough approximation from personal experience.
