I have an old non-descript 12" subwoofer I have used in my system for a long time and I've realized, it really is not that great. Setting my price to $1,500 give or take, I'm wanting good quality so if there's a $750 sub that is good that is bested by a $1,600 one, I'll go for the $1,600 one. But not looking to pay a lot just for the sake of it. I take it this kind of ruled JL Audio out of the consideration, great looking subs but phew expensive...
It's a very small room, so I am as ever size constrained somewhat. It's a roughly 8' x 10' room. I have an old Denon AVR-4802 that works like a champ driving a pair of Infinity Crescendo CS-3008 speakers. About now I'm sure someone is going to tell me that's way more speaker than my little room needs, I don't disagree...however these speakers came to me for a very cheap price and they sound quite good so I haven't found a good reason to kick them out. I have some vintage amps I might end up swapping out the Denon for, but haven't been able to bring myself to do so in years so who knows I may never actually do it. It's a strictly 2.1 setup I use on this system.
More specifics listed below on current setup/goals:
Current subwoofer: Eosone RSP-912
Specs: 12", 120 watts RMS, bass reflex, front ported, 28-150 Hz (yep, no other specs, a sure sign of quality
Space restrictions: Yep, I have exactly one spot a sub can go. And only one sub. Sorry, there is no possible way to work 2 subs in a room this small (in case it gets recommended). Sub can't be bigger than 20" x 18" (L x W), height I can't see being an issue. This is very close to a corner FWIW.
Goal: Better SQ, lower bass response. I know I can get an even better cinematic experience than the fairly decent one I get as is, so I'd like to make the next step to achieve that.
Usage Breakdown: 60% gaming, 35% music, 5% movies (I guess movies vs. games matters in dynamic terms? I always thought they were about the same, but this is mostly gaming system that I do listen to music on time to time).
Brands I had heard were worth considering: HSU Research, Rythmik, PSA, and Seaton (Did I miss any of the direct market brands?
I think that covers it. Advise away please. Would prefer the ability to in home trial, not that I imagine any of these won't clean the floor with the poor old Eosone (Polk) sub I've been using. Funny enough I have a few old Sunfire subwoofers, a True Signature and an Architectural one. I thought of using one of those instead of the Eosone, but in some way I feel the Sunfires are a bit gimmicky much like a lot of Bob Carver products (no offense to fans of his stuff, as I like some of the old Carver amps).
Attached an old, fairly approximate diagram of my room set up. Except there is no where near that much room between the subwoofer and the speaker next to it. Maybe 1-2" max.
