hey

should i get the 10w7 or 12w6v2? i will b powering them with a JL 500.1. which will get me more SPL and SQ?

mike

 

12w6v2

 

My 10W7 sounds like 2 12"s!

 

10w7 all the way. Not only will it sound better and louder, it will require a smaller enclosure.

 

are u fuckin kidding me? 10w7 by FARRR

 

how so? linearly, the 10W7 and 12W6v2 will displace about the same amount of air. the difference is so small, its not worth comparing.

sound quality? there is no difference sonically between the two subwoofers. only difference between the w6v2 and W7 in general is output. the W7 has the ability to handle more power without going into power compression. with the JL 500/1 amp, its going to power the 12w6v2 to its full potential while the 10w7 might not be unless he builds a box big enough so that it'll reach full excursion. then again, the 12w6v2 is also cheaper and will do just as well as the 10w7 with the amount of power he has in terms of output and sound quality.

i still don't see how the 10w7 is better by FARRR

 

Where are you getting power compression specs? Don't pull that up unless you can back it up. Just the size/shape/etc of a speaker doesn't mean shit.

However, I agree with you. If you look at the specs, the 12W6V2 is slightly more efficent and has a greater cone area. Up to the mechanical limits of the 12X6V2, it would be 2-3 db louder per a given wattage. Is that audible? Not to a normal person.

 

never said size/shape/etc of a speaker meant anything. infact, the size of the driver doesn't even relate to power compression. more so its the voice coil and the cooling capabilites of the driver that results in power compression.

come to think of it, both subs uses 2.75" diameter coils and the 10w7 has a winding height of 2.3" long. not too sure about the 12w6v2 though, but my guess is that its not as long as the 10w7's coil. but the point is, with the 500/1, power compression isn't going to be much of a problem unless u start reaching the 1kw limits. not to mention the 10w7 has a higher thermal rating.

 

I was thinking the same thing...how could a great 12" get out played by the best 10"....To me the 10" was a tad louder.....and more accurate!

 

I think they use comparable cooling methods. I would guess that the 12W6 actually has less power compression than the 10W7. The 10W7 can potentinally make alot more heat, but it's greater mechanical stregth offsets that. In this kinda of situation tho, the power compression doesn't really mean much tho. Unless the speaker is a very shitty design, it should have NO more than 3-4db of difference. However, in a 20+ cone concert rig, that can make a hell of a difference.

In his situation, I would say the 12W6 is the better option b/c it's simply cheaper. He's not going to pound the W7 to it's limits with the 500/1.

 

exactly. thast why power compression isn't a problem which i recommend the 12w6v2 anyways. doesn't make much sense to buy a sub and now be able to use it to its potential right?

save a few 10's and get the 12w6v2. i'm sure either route u take, u won't be disappointed.

 

 

Oops, I made a boo-boo:

This "it should have more than 3-4db of difference" should read "it should have NO more than 3-4db of difference."

I edited the post, just wanted to point that out so noone got confused.

 

eh..just for reference, i emailed Jason Sayen:



Hello,

The 10W7 has a longer coil height winding and will definitely handle power compression better over the W6v2.


Thank you,

so i guess the 10w7 handles power compression better than the 12w6v2 anyways :P

 

That still doesn't mean shit. Up to the mechanical limits of the 12W6v2 it might have a better power compression curve. I want to see real charts and tests. The longer coil might actually hurt the performance of the W7 at lower power, as it's cooling relies on the movement of the cone.

If I can skip to drivers that I know - let me point out an example. A JBL 2206 driver will have a mere 2db power compression after 30 secs and one minute of playing 300 watts of pink noise. An Electrovoice EXV-155 will have only 1db of power compression at 30 secs, but increases to 3db at one minute. This can be viewed as the EV having less power compression at a lesser stress level (normal cruising power) than the JBL, but the JBL will have less at peak performance (pounding the shit out of it). I still think the 12W6 would react better at this power level. No doubt the W7 is a beefier driver and will out pound the W6 at a higher power.
