2 vs 1

[KEW]

I keep on seeing threads and posts about dual subs being the way to go, but when people post that they are looking for a $800 sub, I don't see people recommending "buy 2ea Velodyne Impact 12 subwoofers at $365 each (just a random example of a ~$400 sub). Why not?
So while 2 is unquestionably an improvement over 1. For a given budget, is two better than one?
Maybe 2ea. $1000 subs would outperform 1 $2000 sub, but 2 $200 subs might not outperform one $400 sub?
Whaduhya think?

It really does depend on your situation. I use 2 but I have used up to 4 and if you have trouble getting a smooth response 2 can really help. But if you get a quality sub that is correct for your room size it should be fine. It certainly isn't something you should skimp on and if you can build your own then you can get even better performance for your money.

I'd have to say you are correct in your thinking. Two crappy subs together will just give you more output, but it won't sound better than those subs are capable of. A single sub that is capable of better sound quality, if that is what one is after, would be a better choice in my book.

I agree with what John said, more crappy output is still crappy output.

For me, it comes down to extension. Cheaper ehem, less expensive subs typically don't reach as deep. Adding another one will not help with this. For music, when extension isn't as important, stereo subs is fantastic.

If somebody had 400 bucks to spend on a sub, I would almost never recommend dual subs for HT purposes, but might consider it if it was to be used exclusively for music. If the budget is 4 grand however, I think you can get more bank for your buck utilizing multiple devices and probably achieve better overall response.

Lets be really really honest... Those looking at 400 dollar subs probably aren't in a situation where that's gonna be the weak link anyways and response is probably limited by another variable. No need to use TWO to try to correct.

The main issue with a single sub is localization, but with proper placement in most rooms this is a non-issue.

As other have stated Sound Quality is the first factor to consider. Get the better 1 sub over the 2 lesser ones.

I went back and forth on this issue when I was picking out a sub. I looked at alot of factors and finally settled on 1 sub. I could have gotten slightly more output with 2 lesser subs, but in the end what made me go for the Ultra was overall sound quality and extension. I think alot of people start with 1 sub and if they need more, to even out the response, than add another one later. I think it's best to start with one and experiment. It could save you a little money. The second one may not be necessary depending on your room conditions. Plus, it is nice to know you can always add another one later, if needed.

I have one, but if I had the choice, I really would have gotten two smaller subs.

I have a little trouble getting smooth resonse from my single sub - user error probably, or maybe just a really wierd room. And my wife limits where I can place the sub as well...

Also to be considered, some amps are coming out with Stereo ( right / left ) sub outs - so that effect, - athough probabaly minimal due to the nature of the low frequency - would be cool to try and take advantage of ...

I haven't seen any with "stereo" sub outs, rather they have two sub preamp outs but they are both the same mono signal same as using a splitter. If you want "stereo" out, you would use the main R&L preamp outs. Dual sub preamp outs have been around for a long time, they just don't come on all receivers.

I personally went through the same decision making process. I had a budget of about $700-800. I had decided I wanted to go with ED. I had the decision to go with dual A2-300's vs. single A5-350. I opted the dual approach and am thrilled with my purchase. These duals make create more bass than my room, wife and neighbors can handle and this is in an 8000 cubic foot room. I get a flat response down below 20 hz and the placement options that having 2 gives is in my case unparalleled. With duals you can pretty much pick your loaction for placement and get a very even response. Where as with a single I would have to be very specific in placement to be sure to get my best performance. Good Luck.
