2 12" will not be louder than 1 12" off the same amp power. 550w rms on the 2 12" will yield 275w per sub and the full 550w on the 1 12". Double cone area will add 3db but also doubling power will also add 3db so in theory both set ups should be equal since the 1 12" is getting double the power in the sum of 550w rms. Excursion also will play a part in the amount of bass produced. More excursion should mean more air being pushed.
Manville Smith ( JL ) has had numerous discussions with users and he states the exact conclusion as I mentioned above.

Both are good quality woofers ...........head on down to your local shops and audition both and see what you like
then I would also ask myself what you have space for the single w6v2 should take up less space than 2 type R's
again it all comes down to what do YOU like, your the one that's got to listen to the things ............

As posted, 2 Rs should get louder... (for more reasons then just cone area)... to me that means they will 'play deeper'. As far SQ everything posted has been based on opinion.. I think for a better discussion we need to get past 'well, I heard this sub in such and such a setup' and look at something tangable...
Having good sound is largely based on install and application anyway... not just the product used....
Of course having large amounts of linear Xmax/flat BL and low inductance never hurts.. (why arn't we talking about that?)

However, it isn't really fair to compare drivers that are not in the same class. The Type R simply is not on the same level as the W6v2. As I said before, the Type Rs are more comparable to say a W3. Otherwise it's like comparing a Toyota to a Lexus.

I wouldn't be allowed in a lab without knowing the theory behind what I was doing... yet, just knowing the thoery is not good enough which is why I'd be in the lab in the 1st place...
Anyone with a good understanding of theory and practice, can apply the theory with their real world experience and predict a reasonable outcome...
Why don't you contact Dan from adire or the engineers at JL and tell them that having flat BL or large amounts of linear Xmax is of no consequence to a SQ subwoofer and see what they say... [img]graemlins/thumb.gif[/img]

you are mistaken my friend, there are many speakers with ideal parameters on paper that sound poorly, i didnt say that parameters are of no consequnce, of course they are, but you cant tell by numbers on paper if a speaker will sound good, if you believe that. you are a fool. in theory you can make a single speaker that is flat from 20 to 20 but it only exists on paper. you can thoerize all you want, if thoery were fact i guess companies wouldnt have to make prototypes for evaluation they could just go right to production because their leap analysis gave them good bl and x max parameter. in thoery i could own a mclaren, but only on paper its maybe possible, the reality is different
