I am in the middle of planning/constructing a Home Theater in my basement. I have studied multiple subwoofer designs including IB and LLT, but I feel that a sealed sub is best in my situation.
My room will be L14.5' W11.5' H7.5'. The room will be as isolated as possible from the rest of the house, that is why I can't do IB, I would have to isolate a secound room.
The enclosure needs to sit at the front/center of the room, under my projection screen, without sticking out to far. The Max height was 30" and depth was 16". Port diameters, length, and port noise all played into not being able to do a LLT.
I will be using a Crown Xti 1000 amp, but I am not sure which way would be better to wire up the subs. Each Channel at 4ohms 500 watts .5% THD or Bridge 2ohms 1400 watts 1% THD. I will be using the Dual 2 ohm voice coil RLP-18's.
I have modeled the Sub in Bassbox Pro, but I am really a newbie at this kind of stuff so it could be way off! Please have a look and let me know.
I have also factored in a room gain of 3 dB/octave rise @ 35Hz, and I am not sure if this is correct or not.
I can use the shelving filters and PQ in the crown if I have to, but I will also be getting a FBD, to tame all the peaks.
I have included some graphs as well as the original BassBox file, for anyone to play around with.
All your input would be great on this design.
Thanks
