Craig LeermanI am putting together a dedicated system for second stages at festivals, main stages at small fairs, etc. Mostly outdoor shows with local acts, with the occasional regional or small national artist.
I have the highpacks already, and have been using some single 18" W bins with them for now. The highpacks are horn loaded Northwest Two cabinets, loaded with 2 JBL 2226 15" and a JBL 2445 2" horn.
It takes at least 2 of the 18" subs to keep up with the highpacks for most music, and more if I will be doing real bass heavy music.
Elliot ThompsonSo, other words, in order to get sizable amount of punch,
you need one top to two subs ratio.
Craig Leerman My main problem are:
* I don't want to take out tons of boxes, just 2 subs and 2 highpacks. (unless I need to cover a larger than normal area or bigger crowd that is)
* I don't like the look of odd sized boxes, I want the subs to be the same width (about 34" if I remember correctly) so the stack looks neat, and the subs don't end up being drink tables!
* I would like to use my existing inventory of 2226J drivers that were left over from an ill fated double 15 project.
Elliot ThompsonIs that 34" total width for both boxes standing side to side,
or laying down, stacking one W over another?
Craig LeermanI have been looking around for designs and ideas of what types of subs to build that would go good with the horn loaded highpacks.
I was thinking of simple quad 15" front loaded boxes similar to the Community quad 15" cabinets. I have heard the Community boxes at exactly the same type outdoor shows that I plan to use them in and they would work.
Elliot ThompsonThat would work, but, a Quad 15? Why not two Dual 15's
which would be easier to transport?
Craig LeermanBut, I was hoping that somebody would know of a 3 or 4 15" horn loaded sub design, or manifold type box design that I could look at while I am still in the planning stage. Something like EAWs SB1000 for 4 15" instead of 2 18" or a 4 X15" version of the SBX220 would probably be cool as well.
Elliot ThompsonA four 15" hornloaded sub, would be enormous!!! Taking
in consideration you need to have the right amount of
Horn Length (For The Frequency) and, Large Enough Mouth
(For the High SPL) you are looking at a box weighing
more than the EAW KF 940 (365 pounds -> Ouch!)
Craig LeermanSomething in the 35Hz to about 80Hz or higher range. It would be really nice to just have to buy some wood and a few steel grills instead of spending money on new drivers!
Elliot ThompsonIMHO I think 2 Dual Fifteens will be the wiser choice.
1. Two Dual Fifteens are easier to move, than one Quad 15.
2. You'll have better flexability, to achieve 35Hz using
two Dual Fifteens, than one 4 driver horn-loaded sub.
You'll need a 8 foot horn (Quarterwave) and, a 32 foot
mouth to achieve 35Hz.
The only obsticale you'll have are those Hornloaded Tops.
Two Dual Loaded Midrange Horns, are equivalent to 6 - 8
non horn loaded midrange cabinets. And, if they are loading
in the horn, make that more toward 8 non horn loaded midrange
cabinets.
Craig LeermanAny box designs or styles I should look into?
Elliot ThompsonUnder your requirements;

I see Two Dual Fifteens as the only alternative.
Just feed them alot of power, and, have those Dual Horn Loaded
15 cabinets supply more low mid - mid bass.
