[QUOTE="cotjones, post: 2651054, member: 573988"] its the same setup its worded different the only difference is that in the other thread i had 4 10's i kept saying that i wanted to run the different size subs at different frequencies... no one wanted to hear that they are more interested in flameing then helping... but with jl amps i don't think i will have to worry about phase cancellation because of the ability to reverse polarity...(if i understand that concept correctly)... so the problem is that one of the chains will be over powering the other at specific frequencies? so i have another question... is that bad? they are in separate airspaces so it won't compromise the quality of either sub to play at a lesser volume... FOR EXAMPLE: (sealed box 2 subs same airspace, one stops playing, the other one doesn't and blows the cone out of the other one beause of the presure imbalance) the way i see it... if there is no phase cancellation, then i will simply hear the louder size sub at the given frequency more than the lesser, the benefit to this setup is doubling the optimal effective range of the bass, example: 10's play high frequencies better than low bass and 15's play low bass better than high bass... thats just common sense and physics [/QUOTE]
