Hello everyone, long time reader and forgot all about having an actual login here to ask questions directly but I would appreciate any feedback. Here is my setup. Right now I have JBL Studio 235c Center, and JBL 230 (pair) for L,R. My left and right rears are wall mounted Monoprice speakers (unsure model) and are about 2' behind and to sides of main listening positions.My sub-woofer is a single Klipsch SW350. I just upgraded to a Denon X2500H receiver. I think you all can see my weak point. So now I am looking to burn some more money. My initial thoughts were Atmos ceiling speakers but I feel like a sub-woofer upgrade would be more beneficial in my living room. The room is app. 20' x 25' open floor plan type with 10' ceilings where living, kitchen and dining are all in one however listening positions are all located within about 12' of the corner the sub-woofer is located in. Whats your thoughts? My budget is around $500 possibly up to $600 if its a amazing deal or what not. I was considering the SVS PB-1000 or HSU VTF-1 MRK3. When I look at the overall dimensions of the SVS compared to my current its .... confusing? ... how the SVS sub which is only slightly larger then my current sub would be that much better. At the higher side of the range I was considering the HSU VTF-2 MRK 5. Please let me know if I am missing a brand / model or any other recommendations you might have for me regarding the system. My only issue with the VTF-2 MRK 5 may be the WAF and her shooting me when she gets home to see it.. Cheers!
