2 Subs For Music

Just wondering what everyone's opinion was on using 2 subs in a system designed mainly for music.

It's a GREAT idea. There are many aspects you will like with this.
I would personally recommend a direct servo sub for music and get ones that face forward and definitely ones that are sealed.

My preference is to have two sealed subs located close to the main speakers and has been for the last decade.

Atleast two

Agree with the majority, I have two sealed subs. Use them both for movies and 2ch. Dual opposed 15" drivers located on the wall behind the seats.

I don't think you're going to find anyone that says not to do stereo subs for music.

Yeah, that is true. There are "purists" who consider subs a sin.

I was a denier for a long time 20+ years ago because the prevailing recommendation was to get the largest single subwoofer possible and have it booming away in a corner because bass supposedly wasn't localizable and corner placement produced the strongest bass output in a room. That never worked well for me so I would listen to music without the subwoofer playing.
-
Subs are an abomination and you only need one when you do because all bass is omni directional!

I use two subs in both systems. SVS SB2000 pros in the main system, HSU stf 1’s in the downstairs system. The SVS are far superior,and far more current, but the HSU’s are adequate. (For now)See my profile for list of gear.
-
If it's big enough, one sub will do. Otherwise, two subs are a necessity.
-
Apparently I'm one of the few here that dual subs didn't work out for. I gave it my best shot but dual 18'' subs just did not work in my room. I eventually got tired of fiddling rather than listening so it's been one corner loaded sub set it and forget it ever since.

16x22 with the speakers on the short wall. There was a null about 4' from the back wall and I was hoping the 2nd sub would help with that issue. It did not even though I tried it in several different spots.
-
Did you only move that one sub? Or both?

I would say 4 is best, two up top, two down low, essentially the front four corners of the room- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Just one. I started with a single 18 that was getting the job done but when another one came up locally I decided to give dual 18's a shot. I tried the 2nd one in every possible spot in phase, 180 out etc. it just did not blend in so away it went.
Cool story about selling sub number 2 though. A young fellow with a really cute girlfriend came over to buy it. It was a really cold night in the winter and she had what appeared to be wet hair. Try as we might we could not fit the sub in the backseat. But it did fit in the front. He says to her that she's riding in the back on the way home which was the next state over. Didn't seem to bother her in the least and she hopped right in the back seat wet hair and all and away they went. That would not have worked for me in the same situation. The sub would've somehow been strapped to the roof or the trunk first. -
May be a dumb question, but when you run two subs, and you aren't using LFE, do you run one channel to each sub, or both channels to both subs?Sources: Technics SL1200MKII | SME3009 Tonearm | Monster Alpha 1 MC cartridge | Oppo UDP203 disk player | Nikko NT-790 analog tuner | Musical Fidelity Trivista 21 DAC | Preamp: Threshold SL-10 | Amplifier: Threshold Stasis 2 | Speakers: Snell Acoustics C/V | Kimber 12-TC bi wire speakers | Analysis plus Oval 1 preamp to amp | Wireworld Eclipse 7 DAC to Preamp | Wireworld eclipse digital IC Oppo to DAC | Audioquest Quartz tuner to preamp |

For true stereo, use the left preout for left and the right for right. Or if it has speaker wire inputs, you can just run from your left soeaker to left sub, right to right. If you are just trying to cover room nodes I suppose you could just daisy chain them.

In my case, I use the 2 RCA loop outputs on the amplifier, straight (L&R) to each respective sub. I have learned over the years that when you use 2 pre-outs on the same pre simultaneously? It degrades the signal, or shall I say, has the "potential" too, depending on the topology of the pre itself. Sometimes, the signal is severely degraded IME. The way I have it configured now, no degradation but not many amps have this option. FWIW.

Right now mine are run speaker wire out from the second set on my MF integrated. That’s another option…in general subs with speaker inputs are easier to integrate into a 2 channel system…Living Room 2.2: Usher BE-718 "tiny dancers"; Dual DIY Dayton audio RSS210HF-4 Subs with Dayton SPA-250 amps; Arcam SA30; Musical Fidelity A308; Sony UBP-x1000es

Well you found him. So I might just mis understand your "Stereo" Sub comment as there is no such thing in the way Bass works in your room.
If you mean 2 subs as your comment Stereo means than I agree but as actual stereo left and right , no that's not how bass works.
Using 2 subs in a room give you the ability to smooth out the bass response in your listening position, your seating , which also allows you to have some flexibility to where you decide to sit. You can move positions and get a more even natural response with 2 subs setup correctly , not the typical what I see left and right of your system. This is called Co Located which all that does is basically makes the bass louder coming from 2 front positions. What you want is to mirror your subs the best you can. This will give you the best chance at even flat response in your room at your seating positions.Dan
