What is the technical reason why 2 subs are better than one?

My brother has two 10" clarion carbon fibre subs in a 3 cube ported box powered by a pioneer 500watt digital amp and it goes deeeeep and loud and sounds great. Clarion suggested a 2 cube box, but the bigger box is the way to go-much deeper no boominess at all. Price was good for the build quality-aluminium basket, double stiched surround, vented pole piece, 70 oz magnet, 300 watt rms power handling- at 145.00 each. Pretty hard to find all those features for that price and sound very good. just my opinion.

ok newbe to this massage so here is my .02
go with two amps going to two subs will give you a better set-up than one amp to one sub .so if you can hell go with 15" with two 1200.1amps hay why not
go big or go home! hehe
on that note i can only get one sub in and i'm looking at places to hide the one amp
out of site no bing box that is hard part of what i'm trying to do
SO ONE IS BETTER THAN TWO

you can gain 3db by simply adding a second woofer, the same result as "doubling the power" or in effect,adding a second amp, so if you are trying to get louder on a budget,and your existing amp can handle the load ,go with two and both subs should last much longer than having just one.

Theoretically, if you double the cone area, you'll get 3Db. But if you halve the power, you lose 3Db (Same power divided to two subs).
If you double the power, and double the subs, you should get 6 Db, plus a few more from the "coupling effect". So spend twice as much and it should be twice as loud (10Db is twice the perceived volume).
With the same amp, the same space, and the same budget!, two might be louder, but one will have better SQ.(All else being equal)
Any system that's twice the price "should" be better. The question here is "are two subs better than one?"
Kinda like the ported vs sealed question. IMO sealed sounds way better, but costs a lot more. (doesn't do much good to have awesome SQ that doesn't go loud) so I usually do ported boxes.
I have a pair of Rogers LS3-5A's for my home system....beautiful little 25 watt speakers, if you listen to violin solos. Had to raise my kids before I could afford a decent sub and amp to get em to sound good with Zeppelin.

^^^^^Again the important words in there are "theoretically" and "should".
Like Defro stated, there are too many varibles to just say "This will happen....".

Well, it's easy to call BS I guess. Back it up with reason/experience/knowledge.
I used the theoretical term, cause there are a lot of variables, and the best laid plans don't always work out.
In my 25 years in the business, I have heard a lot of stuff that should work, that sounds like crap, and a lot of crap that sounds good, but they are the exception, not the rule.
Got some examples, or real world experience that you can use to refute?

You answered your own question. There are too many variables.
I'm getting the impression you feel that if something costs more then it is a better product and if that person who spent more didn't have a system that sounded better then they would be the "exception".
Need examples or real world experience on that? Just look at some great SQ cars to see that it doesn't take the best product to get the best sound.
