I was just reading back on some topics and i think that i dont need the Universal option if i get dual 2 coils is that true?

Will the dual 2 coils definitely give me a 1ohm load?

Daul 2ohm coils wired in parallel would equal 1ohm at the amp.

As for the universal option I think you might be right.

Universal determines the size of the gap with 1 ohm coils. The gap tolerance can be optimized with the 1 ohm coil, but then a 2 ohm coil will not work. Universal with 1 ohm coils will allow you to recone as a dual 2 ohm if you ever decide to.

If you want a final load of 1 ohm, you want dual 2 ohm. Wire them in parallel you get 1 ohm.

You can select the Universal option, it does not matter and will save you from trying to explain it to someone later if you decide to sell the sub.

does the universal option make the sub perform any better though?? or worse??

x2 on that. I was wondering the same thing. I am about to place my order.

I read back through some threads and was unable to find any information as to the subs performance with the universal option. Hopefully Nick or Scott can provide some feedback on this.

Universal: This option gives you the choice to later chance the impedence of your voice coils. You can change from dual 2

It doesn't effect the performance, just gives you more options later on down the road.

someone correct me if i am wrong. if you choose the universal option, it has an effect on motor strength?

My personal opinion is....... if you can't figure that a D2 ohm load will give you either a 4 ohm (series) or a 1 ohm (parallel) load, then you don't need to be spending a lot of money on woofers yet.

still hoping scott/nick can chime in on this. im interested to find out too...

This is how i look at it: D2 coils are "bigger" (wound) than D1 coils. the added machining to fit em takes away motor strength. couple that option (universal) w/ a D1 coils and have less motor, and more gap to lose electromagnetics = lower performance.

my theory is that the strength of subs would be as follows (from strongest to weakest):

gap optimized for D1 (not universal) w/ D1 coils = optimal gap clearances. more motor strength overall = strongest

gap optimized for D2 (same as universal) w/ D2 coils = optimal gap clearances. less motor strength overall = stronger

gap optimized for D2 (universal) but w/ D1 coils = not optimal gap clearance, less motor strength overall = strong

someone correct me if i'm pulling ideas out of my ass, or confirm if its correct.

You are never going to hear a difference.

Maybe..MAYBE a tenth on the meter. Audible? Nope.

i figured it wouldn't be a big diff, but just wanted to confirm my theory or have it shot outta the sky. thanks for the info nick!
