I've been lurking here for quite a while and trying to find a good thread that pertains to my particular issue, but I have been unsuccessful. My question pertains to the sound quality and placement of subwoofers in my great room (which will be doubling as a movie room for the time being until I can finish one in my basement). This is a new construction home, so I do not have the ability yet to be able to test my configurations or see how much bass I get in the room. I'm concerned with how much bass I might potentially lose due to the open floor plan and no wall exsiting behind my main listening position and my couch.
The layout of my room is attached below:
You will see the approximate locations of my speakers relative to my fireplace, couch, and tv in the attached image. My setup currently consists of the following:
Denon 4520ci receiver
2x Polk RTiA7
1x Polk CSiA6
4x Polk 80F/x RT (ceiling speakers)
(subwoofer or subwoofers(2x) undetermined at this time)
My great room is 15x19(x9' ceilings) and the room opens up another 20-22 feet behind the main listening position (couch) into a breakfast area, kitchen, and sunroom. Will I lose all of my bass into those areas due to there being no planned wall behind the couch? Will I basically need 2 subwoofers to be able to get a decent enough bass response/sound in the main listening position? Is my proposed positioning of the subwoofers good? Will I lose the effect of the lower range of frequencies (80-200) from my RTI A7s?
I would likely be in a 1 subwoofer situation for a short time while I save for an additional sub. I'm also open for subwoofer recommendations. Fortunately since the 4520 has the SubEQ HT, it should make adding an additional sub (if necessary) a bit easier.
Any help in making me feel better about my open-concept new home would be greatly appreciated!!
