I am currently using Klipsch RW-12D subwoofer for both watching movie (75%) and listening to music (25%).
My current setup is:
Sony XBR-55HX929 TV
Oppo BDP-93 Blu-ray player
Denon AVR-3311CI AV receiver
Klipsch RF-52 II (front)
Klipsch RC-52 II (center)
Klipsch RB-51 II (surround)
Klipsch RW-12D subwoofer
My house has 2 stories. My living room on the first floor and is 16.5' (W) x 13.5' (L) x 9' (H), i.e. about 2000 cu-ft. It is carpeted with concrete foundation. The TV is on the 16.5' side. There are walls on 3 sides and the remaining side is an entry way that leads to the dining room, kitchen, and stairway to the second floor. I have attached some pictures of the current setup and floorplan.
The RW-12D used to be at the corner next to the front left speaker and it performed the same as the current location. Since it was blocking the closet door at the corner, I moved it to the current location.
Given this, do I need to count the space on the whole first floor? If so, there are close to 5000 cu-ft total for the first floor.
I'd like a subwoofer that has more bass extension that the RW-12D and is almost the same size as the RW-12D. Due to WAF and size limitation, I am looking for a single subwoofer solution and have ruled out the following: HSU VTF-3 MK4 and VTF-15H and any Outlaw and PSA subwoofers.
My short list includes the following subwoofers now:
SVS PB-1000 (not sure whether this is load enough for my space?)
Do I need to get a ported subwoofer for my space? Currently, I am leaning towards the HSU ULS-15 or Rythmik E15.
Please let me know your opinions. Thanks for your help.
Edited: Changed size to almost same as the RW-12D. Smaller size is not realistic.
