ltsv38,

it is an interesting solution for lower midrange horn.  If I use something like this for Macondo ‘s fundamental channel (but of cause spherical) then I would flip the horn with driver up and run the neck longer to accommodate a slower, exponential-like profile. The objective would be to get the same 250 cycles but more by the horn EQ then the driver extrusion. I do not know the 2482 driver but all of the 2” exit drivers have in my estimation some unpleasant behavior as lover knee when you stress them to go very low. They might produce sound pressure at marked lower knee musically they do not do well dynamically when they stressed to go very low, they developed some mild, and some of them not mind, compression. I think the reasons is because the drivers are optimized to deal with 2K-5K and the spaces in the driver and within the phase plug are to too small for higher pressure of the longer waves. So, as the driver pumps more at lover knee the bouncing pressure from phase plug over damps the diaphragm. ltsv38, no one would tell you if you have this effect and you need to  see of your lover knee of your 2482 channel  (lower midrange) sounds as dynamic and your upper knee of your uppperbass channel.

Rgs,
