I'm seeking opinions for a sub upgrade of my HT setup, for both models and implementations.
I currently have a 3.1 setup with Infinity Sterling SS2003 (non-ported 8" woofer, 1" tweeter) and Infinity Sterling Center and a single BU-1 Sub (8" down-firing, side port, 50W RMS, 45-150Hz) being run from a Denon AVR-S730H. My main reason for looking at an audio upgrade is that the sub doesn't reach very low. I can't really hear anything from the sub below roughly 35-40Hz, in line with the specs. It does fine above that. The system used almost exclusively for TV and movies. I'm mainly looking at front-firing, ported models, and I'm open to the idea of either single or dual subs, and possibly down-firing subs. I don't need to shake the house to rubble, but would like to play lower sounds. Size isn't really a limiting factor, but I'd prefer smaller to larger.
The room is a finished section of the basement. It's a rectangle in shape, roughly 32.5' wide, 12.5' across, and 7' high (~2850 ft^3). It's set up so that the viewing area takes up about 40% of one end, across the 12.5' side. To the viewer's right is a wall, and to the left the open space of the rest of the room. Seating is a sectional sofa in the corner where the right side and rear are directly against exterior walls, which prompted us to to drop from 5.1 to 3.1 years ago. Listeners are about 11'-12' from the screen/speakers. L/R speakers are about 14'-15' apart.
There's a door to an office, another to the unfinished side of the basement, and stairs, all at the farthest end of the room. Doors to the other rooms and at the top of the stairs are typically closed when watching, making the room pretty much a closed box. The room is carpeted, and has dropped ceiling tile. The near wall and rear are exterior walls. Behind the screen/speakers and the far wall are drywall.
I picked up a 2nd BU-1 because I thought I had a mid-range hole in the sound, and a bad transition from sub-to-speakers. I was prompted to check settings to make sure that I didn't set the AVR improperly and/or set a cutoff for the speakers, which seems likely. I'll check and make those corrections, and I plan to test setting each sub as L/R with their respective speaker and signal, tell the AVR that I have no sub, and send full-range to L/R fronts.
Is that a reasonable setup to have 2 "big" speakers, or should I set the sub(s) for LFE driven by the sub pre-outs? From what I've read, a 2nd sub could help fill in dead spots of the room, and separation of L/R signals could help avoid interference. Any thoughts on this appreciated.
I'm trying to spend as little as possible to get lower frequency response and non-boomy bass. Lower doesn't necessarily mean 10Hz. Remember, I'm coming from a single sub spec'ed at 45Hz and 50W RMS!
I've pretty much ruled out the "usual suspect" budget subs such as the Polk PSW-10/505, Monoprice 9723, Dayton SUB-1200/1500, BIC F12/PL-200II, etc because of lack of either power or clarity, from comments and reviews, or their price relative to candidates below.
Candidate subs include:
Some I can consider getting 2 of, probably one now, and potentially adding 1 later:
Infinity Primus PS410 (10", 300W/500W RMS/Peak, 27-150Hz, front firing, rear port) $130 refurb
Infinity Primus PS312 (12", 400W/700W RMS/Peak, 25-150Hz, front firing, rear port) $200 refurb
Premier Acoustic PA-150 (15", 250W/1000W RMS/Peak, 25-180Hz, front firing, rear port) $250 new
With the Infinity subs, I think I've found how to avoid the fried amps, so I'm asking for opinions of how they perform at their best. Considering the equipment I'm starting with, specs and prices of the subs listed here, I'm leaning heavily towards getting 1 or 2 PS410s, unless commentary on their sound quality is poor. In that case, I'd have to think hard about 1 or 2 big PA-150s, or stretching my budget.
If I stretch my spending amount, I could consider one of these if it was a notable improvement over two of the previous:
RSL Speedwoofer 10S (10", 350W/???W RMS/Peak, 24-200Hz, front firing, front port) $399 new/direct.
SVS PB-1000 (10", 300W/720W RMS/Peak, frq resp varies, but sub-20Hz, Front firing, front port) $500 new/direct, $440 new online.
Monoprice Monolith 10" Ported (10", 500W/???W RMS/Peak, frq resp varies, but sub-20Hz, Front firing, front port) $550 new/direct. Sales go lower.
From these, I'll wait to see what prices BF sales bring for the Monolith, PB-1000, and Speedwoofer 10s, which I like in that order on paper.
A Black Friday sale on a Monolith sounds great, and I'm sure 2 would be even more awesome, but considering the prices and quality of the other equipment, I wonder if they're over-the-top compared to 1 or 2 of the cheaper subs and the rest of the speakers.
