2226H jbl folded horn plans

Gud bass everyone!I have 4 2226H 15" here on my stock.Can someone share me a folded horn plans for these speakers?I will use them outdoors so a long throwing bass folded horn if possible.We use to do outdoor live band rig.Im using 4 w bins right now(Keele's bin) for our bass with 2240H drivers in them.We need more bass and kick.Thank u very much guys!

Hi!Thanks fellow pro audio lover.I like the design very much & i also know that it would sound very fat.My problem lies on the size of the box.Im planning to build the folded hoorn featured in the speakerplans link,something like the SL36 by Cerwin Vega but a smaller version...will it be possible guys?The small truck that were using won't be enough to take all our stuff.Is there any smaller one which this one will fit?...one driver per box if possible?Any idea?????anyone???Thank u!

the 215 horn bin i have just built is supposed to be for a pair of 2226s...





i made mine shorter, but kept the footprint and layout. the only exception to this was changing the nature of the access panel flange arrangements which as you can see from the picture above, eliminated any mitre cuts greater than 45 degrees. stand-alone performance of my modded cabinet has indeed made me wonder what a pair of the correctly proportioned bins loaded with the prescribed woofer might do...

alternatively, you might like to try the martin 215 mkIII which could also be loaded with 2226s if memory serves...



i've just checked in the manual actually and it doesn't mention them, but i'm sure it's been done. this would be a little punchier, but not quite as much extension as the other 215. of course, like most horns they really come into their own in stacks, so you'd probably find yourself wanting to build some more as two a side is where things start to get interesting. three's where the real fun starts.

i don't think splitting the box down the middle to make two will work properly... bifurcated horns is a topic i'm not really understanding at present, but as i follow the drivers "share" some of that final flare.

e140s... now that's a different story. what you really want to put them in is some of these...



...for the ultimate in tight, fast, punchy and musical kick bass. only downsides are that you need a subwoofer to complement them (see the giatt sub thread for my latest attempts to make something to fulfill that role for my 215mkIIs) and that they are large, heavy, and a bit of an odd shape. they are way cool though and allow you to cross quite cleanly to a medium format horn midrange, such as a 10" or 12" at as much as 250 Hz.

that 215 i've just built isn't very kicky, but that might also be the driver choice and box tampering. it's much more "subby" than a mkII bin, gets a bit honky at 160 Hz crossover or even a bit lower, but i also unplugged it for a while whilst doing some more evaluating and plugged in the giatt instead. all of a sudden the music took on a whole 'nother depth as notes that i hadn't really been noticing started shaking the room... so it's all relative.

i'm all for split bass, if you can handle the processing complexity (read cost) it's the way to a fuller sound. dedicated straight horn doing the kick and high bass, crossed to some esoteric subwoofer solution. i like things like the wicked one and giatt (and indeed the x1) because they offer stand alone sub bass performance to supplement a kick bin, without the need to resort to huge stacks of mega-unwieldy horns. the big boys have lab subs, but i couldn't live with them!

that's right ian, it's screen grabbed off the 215 datasheet. i think one of the reasons that nobody builds these is that there are no available plans to work from. i do keep intending to measuring up a pair next time i've got some in bits, it'll happen before too long i dare say... not so sure they're that easy a build though, especially that bit in the throat that (most of) your ass bins don't have.

regarding the 2 x 12"... yup. that's exactly what i had been thinking myself, only wasn't that a trap cab too? i got to be thinking about this immediately after having visited noise control audio and spoken to raey for the best part of a morning, hence posessing a bent to make a box with no parallel walls and a constant flare expansion. i ended up redesigning the 215 for 12s on scraps of paper until i had something that looked almost entirely like an ass mx1200, which i feel kind of validates the design process!

i tested a JBL2226H in a HD15 http://www.speakerplans.com/index.php?id=hd15horn i was very impresed, lots of kick and plenty of volume.
