Hi all.
I am working on solutions to anemic bass in my home theater. . . Well, not entirely anemic. I think it's the "slam," room pressure aspect that is missing. The bass quality is actually great (music) and scenes such as the opening of Edge of Tomorrow are earth shattering. But, that's low extension.
Room:
This room is somewhat oddly shaped, kind of like a plus. 120X220 (inches) X8 (feet). The right wall length is 220. The left wall length is 236. The room is sloped. At its highest point it is 8 feet. That point spans about 5 feet across and then it slopes sharply to the wall. There is 106 inch screen in the front of the room. I have a 5.1 setup. Front left and right speakers are toed inward toward the listening position and fairly close to the side wall and a couple of feet in from of the front wall. There are two windows in the room, both covered by wooden blinds. One is sloped, almost like a skylight. The other is small. Both are within the plus portion of the room (two alcoves that are in the middle of the room to the left and right of the sitting area). The floors are wood. I have a 9X12 area rug in the room that is thick and on a furniture pad. The room initially was extremely reverby. I consulted with Gik and got a bunch of room treatments. This made a massive difference in sound quality in the room. Just massive.
Speakers:
B&W 603s3 fronts
600 series center
685 rears
Subwoofer: initially SVS 10 inch ported sub. now, PSA s3000i. Moved the SVS downstairs to an open and large living room (much bigger room). The SVS slams harder than the bass in my theater in some frequencies. This is obviously not the fault of the s3000i.
receiver - denon x4100 . . . calibrated with Audyssey x32
I really need to do some measurements, but I need a mic. I've done the subwoofer crawl. Seems the left front corner works best. Sub is placed in between the left and center front speakers. My questions:
- Does orientation of the subwoofer matter? Since I've had it (January or so), I had it oriented so the drivers pointed at the left and right speaker (perpendicular to listening position). This morning before heading to work, I turned it so that one driver is facing the listening position.
- Should I be concerned about interference with my left front speaker if it is too close? I moved the sub closer to the left speaker, about an inch away from it, slightly behind it. This gets the sub much closer to the corner.
My immediate impression was that these two changes improved bass output. But, I need to do more testing. I think I am probably fighting a bass null zone.
