I'm designing a 4-way setup for a mobile DJ system. Using some parts leftovers from other projects.
Crown XTi 6002, Crown XTi 1002 per side - DSP dBx VENU360
Lows JBL 2268H 18" x 4
Low-Mids JBL 2206H 12" x 4
High Mids JBL 2380 Horn /JBL 2450 2" driver x 2
Highs JBL 2402 x 4
I also have a pair of McCauley 6338 12" drivers which would probably do a decent job in a horn loaded configuration. Or go to some newer neo drivers to further reduce the weight of the low mid section.
System is as pictured thus far, I started with dual 12" low mids per side and I have the drivers and that combination sounds great for a playback system. To keep weight down and facilitate easier handling the MF & HF sections are separate. Recently changed the top end from 4 x JBL 2404 bi-radials to the JBL 2402 bullets to tighten up the vertical pattern.
On the note of pattern control, I'm now thinking about tightening up the low midrange pattern control from the dual 12". The baffles will be canted or splayed out between the drivers to widen the horizontal pattern. Same for the mounting baffle on the 2402's, they will be splayed out 20 degrees per side for horizontal pattern.
Having used the old Don Keele single 12"/15" low mid horns in the past, got me to thinking about a change on the low-mids to a horn loaded configuration to tighten up the pattern. That could also result in a weight reduction, by running a single 12" low-mid driver per side.
Low-mids will be crossed over at 120hz & 1000-1200hz to the mid-horns. I'd like something as close to the mid horn, nominal 40/50 degrees vertical and 100 degrees horizontal in the range from 250-1200 hz as a starting point for discussion - if that's even attainable.
The front baffles are going to be slanted downwards ~15 degrees to keep sound down over the dance floor. Many halls today have sound level restrictions and some have managers running around with Radio Shack SPL meters during the shows. Additionally, it's just a better way to go to keep as much of the sound on the dance floor and out of the seating areas.
Appreciate any ideas.
