Air Displacement for the 10w7 is 141.3cu. in.
Air Displacement for 2 12w6v2 is 293.8cu. in.

^^ that's at full XMAX....meaning if you used one 10w7 at full possible power, and 2 12w6v2's also at full possible power (in rational boxes), the 2 12's will move more air and thus increase the pressure(SPL as compared to the 10) of the air surrounding the sub(inside the car).....

 

i'd go with the 12w6v2

 

at 500 watts the w7 is louder like i said, not running two subs at max power, AT 500 Watts

 

one 10w7 will not move as much air as 2 12w6's.... if you run them both rationally(not meaning reasonably--meaning built to ratio of eachother), you're going to get more SPL from the 2 12's because they'll displace more air when moving...You're comparing apples to oranges unless the boxes/installation and power input is rational.....then you can start to compare....

if you take 2 12w6's in a small sealed box and a 10w7 in a wall tuned to 50-60Hz, you can expect the 10 to be louder.....

 

Had a 12w7, replaced it with 2-12w6 v2 , I can not be more satisfied. The sound from the W7 is vastly different than the W6's. Running 1000/ 1,500/5, 300/4. (dolby souround sound)

 

cant wait til after christmas...
by then (hopefully) i'll have a custom box built by then.
and i'll put the 12w6v2 in my g/f's 4runner

 

hey he didnt answer were to get the 10 s at i want .....??please

 

have any pictures?

who are you asking?

 

heres a mind bender... how to calculate a 10w7 to a 12w6v2 with this chart

3) How do they compare to the W3v2's and W6's in terms of output?
10W7 has 90% more displacement potential than a 10W3v2 (5.6 dB)
10W7 has 114% more displacement potential than a 10W6 (6.6 dB)
12W7 has 158% more displacement potential than a 12W3v2 (8.2 dB)
12W7 has 166% more displacement potential than a 12W6 (8.5 dB)
13W7 has 55% more displacement potential than a 15W3 (3.8 dB)
13W7 has 144% more displacement potential than a 15W6 (7.7 dB)

 

or you could checkout a Crossfire XT 212 .... yum

 

If those are your only two choices, go with the w6v2. I had a 10W7 for a while in both a ported and sealed box. I wasn't satisfied with either setup.

I sold it for an Adire Tempest which killed the 10W7 in SQ (in my opinion anyway). I don't think I'd ever buy a JL sub again, their amps however are a totally different story.
