Help needed for second Subwoofer
I am working on my home theater and need help to find a second subwoofer (design and subwoofer).
Current Subwoofer and other info
- I have one mini-Marty with UM18 and iNuke 6000DSP.
- Due to previous home space constraints, the woofer is installed on length side (2x2 side). Sub was laying flat on floor facing to the front.
- Can I design the other sub standing upright now ? or have to follow same design ?
- Both subs would go behind the projector screen.
- Any other design subwoofer which is better and will complement what I already have ?
- space behind screen is 2.5' (Room Dimensions W10' X H8' X L21')
- Which subwoofer ? UM18 ? LaVoce SAN184.03? any other ?
- Budget is flexible but not as flexible as NSW6021-6
- Don't listen to reference levels
- Future HT speakers would be from DISG (Kef's as of now)
Any help would be appreciated. Thanks in advance.
