Alright boys, I am going to blaze a new path on the 4722. After going back and forth and reading over all the JBL tech docs, I am ordering the mid/high section off the 3730 which has a single 6.5" mid-freq driver (195h). It comes with all the brackets, the passive network, and the driver. The 3730 uses the same wave-guide as the 4722, but it has a different rear housing since the 3730 uses a screw in 1"CD. Otherwise, they are identical. I was going to piece it together, but not all the parts are sold separately and it actually comes out cheaper to buy the whole thing. I will ditch the 3730 wave-guide and put the 4722 in its place. All the mounting hardware should work perfectly.
The passive crossover is set at 450 Hz and 2 kHz. My goal is to run these passive, but I also bought
DSi amps in the event I need some PEQ or need to change parameters and go active. This will be a learning process and I hope I can rely on all my friends here for help if needed. I will try to run everything vertical as designed by JBL since I am at 15' from the screen but I can also lay the L/F section on it's side to gain back 4.5" if needed. The mid-horn adds 18" so if I lay the L/F section on its side that gets me to a 14" increase in height. I have read the 3732 images fine at 12-15 ft and it is 26.6" higher than the 4722. I hope to be fine at 15 feet with either 18" or 14" increase in height.
The mid/hi complete section is $515 shipped. Not that $500 is chump change but it was a whole lot cheaper than trying to piece it together which was impossible anyways since none of the brackets are sold seperately. The breakdown is as follows.
$1150 - 4722
$515 - 3730 mid/hi section
$275 - 2453H-SL
$1940 for kick butt passive 3-way (hopefully)
I am going to buy one to start with and see how it works out. If it's a fail, I have made more costly mistakes like throwing rods through the sides of cylinder blocks
