Marvel Posted January 27, 2014 Share Posted January 27, 2014 I'm looking for a simple to build midbass horn cabinet to work with a 10" or 12" woofer. These would be placed on top of a pair of MWM bass cabs. Currently have a pair of JBL 2365A horns for the top end, and want to move the low end crossover a bit higher to help prevent overload in the throats of the JBLs.

Use EVM-12L, B&C 12PE32, or similar mass corner driver. Enough info to get it built (EV TL1225). May be crossed at 150hz. http://s56.photobucket.com/user/dkleitsch/media/212generalplan.jpg.html http://s56.photobucket.com/user/dkleitsch/media/212mantaraycutplan.jpg.html Cut it down to 19" high (internal) from the 38.75" as listed. One horn may be used from 250hz, a stacked pair from 150hz. B&C 12PE32 or similar mass corner. Four more part F required for four boxes. No brace 1x4x18 with 30° cuts needed now. I have used both 1/4" and 3/8" for the vertical expansion ramps (part G). A (poor) photo of the 212 MantRay in one piece, about 30Wx24Dx40H. http://s56.photobucket.com/user/dkleitsch/media/MilesAdamsBand3.jpg.html Randy built these two years ago. The motor board is spot faced 1/4" for driver clearance 11" OD, 9" ID. The original MantRay 212 circa 1981. They proved to be too large for most stages, hence the narrower 2012 version. These could be built as single height, about 17" or so, 48" wide. Edited January 28, 2014 by djk Quote Link to comment Share on other sites More sharing options...
Marvel Posted January 28, 2014 Author Share Posted January 28, 2014 Dennis, Thanks for the plans. I'll try to draw them up to make sure I understand... Makes me wish I hadn't sold the EVM12Ls that I had. Bruce Quote Link to comment Share on other sites More sharing options...
