Hello,
Can you provide the room dimension (LxWxH) as well as positioning details? I think that it's a very important information to provide a custom-advice for your room.
Concerning gear, my advice for the AV receiver is the same as @deep_333 but I would advice for different kind of speakers for this dual-purpose setup:
- Replace your AV with Marantz AV10 system (processor + amp) or Anthem AVM 90
- Replace your speakers with something that can handle music and can be driven with a good HT AVR, such as the Grandinote towers.
Those are 8ohm simple load, high efficiency and huge power handling...The line arrays (from 8XL to 36 😱) models are pretty room-independent so you can live with really minimal room treatment.
--Front/Center/Right: Mach 2s, 4s, 9s or 8XL floorstanders (depending on your budget)
-- Surround left/Surround Right: Mach 2R (bookshelf) or Mach 2 (towers)
Whit this hell of a setup, all the speakers will provide Serious Bass but any HT fan would use at least a couple of subs :)
For subs I can advice about 2 or 4 (better) SVS 2000/ 3000 to shake your chest, depending of your room size/ budget.
For music reproduction the Grandinotes are totally different beasts than the aforementioned ones...I strongly advice to find a dealer and listen by yourself...
There are several YouTube videos about Grandinote and, in one of them, the Mach 8XLs hit 116 dB of SPL in Axpona 2024 with no distorsion at all 🤣!
:)
Happy listening!
