Speaker/sub upgrade options for 5k budget HT/gaming
First time poster, long time lurker.
I am looking to upgrade. Budget $5k. Can you recommend me speakers and sub?
Current setup is 4.1 with Denon x4500h, 4x Elac Debut 6.2 bookshelves, and 1x Hsu vtf 3 mk 5 hp subwoofer (behind the couch).
Looking for a 4.2 setup, TV stand won't fit a center. Maybe further upgrade to 7.2 in future. No acoustical treatment currently in room. Listen to about 45% HT, 45% gaming, 10% music. I listen at both low and high volumes depending on the time of day, so setup needs to sound good at all volumes. I also don't want to get separates in the future, prefer easier to power speakers that sound good with my Denon.
I have a HT/office room that is 12x15x8 ft. Listening space in room with TV and speakers is 10x12x8 ft (other part of room has an office desk) and MLP is 6.5 ft from front speakers and 3 ft from side speakers. I don't want speakers or subs to over power the room, and not much floor space, so 2 massive subs won't fit. Not sure if floorstanders are good options or stick to bookshelf.
Measuring things I can maybe fit 15x15 inch sub max behind each front speaker, but will be close to the walls. Also gives me more placement options for sub crawls around the room, such as beside the couch or but office desk, the Hsu only has really 1 place it can go. If subs sound good up front or elsewhere I could move couch back at most 6 inches, giving me 7 ft from front speakers, there is a closet behind the couch opposite of the Hsu. If large subs are necessary could experiment with putting front speakers on top of them. But really want to fit 2 good subs in room with placement options for even bass.
Speakers currently considering:
Klipsch rp8000f (FYI large footprint puts this close to walls)
Svs ultra bookshelves
Svs prime pinnacle
Ascend Sierra 1
Ascend Cmt 340 se
Subwoofers currently considering:
Thanks for your time and suggestions!
