need HELP with smallest cabs plans

i need help in designing cabs that are very small i am a hobbyist and do a couple small gigs 100-400 people,

my speakers are

professional.celestion.com/pro/p ... s.asp?ID=4 (15in)
professional.celestion.com/pro/p ... s.asp?ID=2 (18in)

i would like a 15 kick bin or mid bass design and a 18 inch low bass design
the boxes should be small as possible and lightweight since i dont use them to make money in a real way and also i store them in my house
so space is limited

IMHO you would have been better going with either 2 of the 15" a side or 2 of the 18" a side and not mixing them. Because of Group Delay it is not as easy to integrate 2 different reflex designs as people think.

I have a very simple 80L box design (45hz port freq,) for the 15" driver you mentioned but because of its low QTS* it does need a fair bit of bottom end EQ.

It should be fairly simple to design a cab for the 18" drivers.

* Not ideal for a reflex

my idea is to have 1 15" cab and one 18" cab per side so i end up with four boxes or six incuding the tops i already have the tops designed..
do you have any suggestions (plans) for the 18 low end bass and the 15 kick bass

Can you post the design for the 18 inch celestion?
