Hi all,
Recently I moved my gear into what we used to use as the dining room.
The idea was to create a media/cinema room and it works really well with the exception of my bass problem.
The screen, front speakers (kef iQ5SE) and DIY Monolith sub are positioned in front of a bay window, the sub being directly behind the TV against to the low wall of the bay window itself and the Kef's either side of the tv.
I've gone for a 7.1 setup and wanted my seating position to be away from the rear wall so it's a decent distance from the rear back speakers and level with the rear L&R ones...
This is where the problem arises, if I move 2' closer to the screen the bass from the sub and fronts is full and quite loud, move back closer to the rear wall and it sounds good too - from my seating position it's almost non existant from the sub and/or fronts. It almost sounds out of phase and hollow (it's not out of phase and I have tried switching sub and fronts in all combinations)
I've read a little on the googleweb and understand that the centre of a smallish room is often the worst place to sit due to the wavelength of bass notes.
Would adding another identical sub in a different location (not that I have many options here) fix the problem or should I just start from scratch with positioning?
Diagram not to scale , the room is 14.5' from bay to back wall and 12' across.
Any advice would be great
