My inspiration for my 25hz design BUT that JBL is a BEAST. If there isnt a design out there I am sure you could design one yourself.
Josh, this is more of what I am looking for but for the 2242:
Big badazz midbass monsters to go with big badazz bass cannons...hmmmmm sounds like what i'm talking abouthere is a very rough guesstimate of the jbl horn. I've been curious about it forever, so went ahead and gave it a shot.
max spl is pretty awesome. excursion minimum is in the 40's, so a high pass below that would be necessary. 9mm excursion get to 134db though and the jbl has more in the tank than that.
it is a big badazz midbass monster. two ported cabs get up around 131db tuned similarly, so the horn is equal to about 3 ported cabs plus or minus. this one is 24" internal wide, 25.5" total width. that is a little wider than the truck pack friendly width of the 6118 which is a little under 24" total width.
with under 80hz covered, some sealed cabs for the 2242's could be an easy start.
do you have dsp to control the crossover points on the 2242?
I think you are chasing the audio dragon. I've used a lot of JBL 2241/2 as midbasses, and once in a horn (2 in each - not my design so I can't post it) but ended up using a 2225 on a midbass horn with an 8' path length IIRC without digging up the old notebooks. I don't see any advantage to the horns over sealed unless you have very little power, especially over such a narrow BW. I'd do as LTD suggested.DSP is not an issue, but....I still do not think sealed cabs are going to make that "magic" mid that I'm looking for. I could be wrong but I'm wondering if some guys "ears" just like the sound that comes from a horn loaded type enclosure. I could also just be chasing something that is all in my mind.
