Yeah, I'm currently running a 4.1.2 set-up, which I prefer over the 5.1.2 set-up, given how bad the center channel sounds to me. I meant I dove in quickly on the sound side of things after upgrading my TV, making some mistakes I won't make next time. Bought a receiver (Sony STR-DN1080) without looking too deeply into specs. Bought a 5 channel system because of the price (Jamo S 803 HCS), quickly added Atmos height modules (Jamo S 8 ATM). Next time, I'll probably start with the center channel, or L/R channels if I wind up being a phantom center person long-term, and then build out from there. Lessons learned. But the main takeaways - I'm very glad that I've ventured beyond relying on a TV's built-in speakers and I'm glad I didn't go with a sound bar, which, sound quality comparisons aside, couldn't possible be nearly as fun as this.
I just got a Monolith THX 10" subwoofer, after another subwoofer I bought died after a few days.
@shadyJ, you were right--the room definitely wants more subwoofer (whether or not my wife does is a different story). I will say--it's definitely way smoother/subtler than I would have guessed a few months ago, when I knew even less than I do now--I guess I'd never heard a subwoofer with proper/flat-ish frequency response before. Was a nice surprise. Also makes me think that down the line I'll be more likely to successfully sell a larger subwoofer to my wife if it's flat-response. (She doesn't like to be "startled," which I think can maybe happen more often with subwoofers with boosts in the mid-bass frequencies. While I've never heard one before, I think the Speedwoofer 10S would have been the worse choice in that department.) I've rambled enough. Thanks for the recommendations and advice,
@shadyJ .
