Done right they are very impressive. [img]smile.gif[/img]
They are very hard to do right.. :(

My recommendation would be to pay an experienced person to build it or help you with it, or stick to a single reflex (4th order) bandpass.

who is an experienced person in bc ?
i need plans so i can make it

go see cartunes. they will help you out with that.

and thay said get the experienced person named PAT for what you are trying to do
so hi pat can you help ?

done properly the 6th order series tuned pandpass boxes are impressive. just look at the one jl has for there w7. but yes they are hard to design and build. if i were you i would stick with the abc it will perform similar to the 6th order box

what i would like to make an abc box but i need to port the A box into B box ,C box into B box and i need to port B box out to a horn .
where do i start ?
the subs are focal 27h

In my humble opinion, the first place you need to start is not with that woofer. That woofer belongs in a simple sealed or vented box and that is it.

i have 2 of that sub so why not

for soem reason i think that you are looking to compete in spl and have good sound? am i right? why not concentrate on one or both but do it by having 2 boxes. one for spl. which would be a ported enclosure. nothing fancy just ported. and one for sq, sealed.

please call me at home im home all day. we can meet today at a starbucks to go over it. but it is obvious that you went into the stores and asked about spl. that would be the only reason they sent you to me. and to reciprocate this, if you want a kickass sq box. go see hzemall, cartunes, georges or audiolines or anyone that will byuild you a great sounding box.

ill make that sun of a biatch loud. they'll make it sweet.

i am a tough man to get a hold of in the off season. i have a family and business that i take care of in the off season. so if i offer this window of opportunity...please call me
