I'm thinking of making a pair of 3-way cabinets for mobile dj'ing.
The drivers I'm considering (on a budget) are as follows:
Eminence Sigma PRO-18A 18" Cast Frame Driver
http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=290-427&scqty=1
Eminence Beta-8A 8" Midrange Driver
http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=290-404&scqty=1
Eminence ASD1001S 1" Compression Driver
http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=290-525&scqty=1
They will be powered by a QSC 2450 Amp: 500w RMS x 2 into 8 ohms
In photoshop I overlayed the frequency response curves as you'll see in the posted image (sorry about the crappy resolution, best I could do grabbing graphs off the web).
I'm pretty sure these drivers should work well together, please let me know if you think otherwise. I'm sure I could do better with more expensive components, but I'm on a budget.
Do you guys see any problem with these components being used to gether?
Assuming the components work ok together, I really need help designing the crossover. I suppose I could use a premade one from parts express, but I'm worried that they won't level out the sensitivities well.
Would one (or more) of you be so kind as to recommend a design? Assume I know next to nothing about how to design a crossover...but I DO know how to read a basic schematic, and I'm pretty slick with a soldering iron.
Obviously I need the crossover design to not only attenuate at the correct frequencies, but also to level out the sensitivities (as you'll see from the graph the sensitivities of the drivers vary substantially).
It would be super extra nifty if you could also include the exact names of the components, and out of this world spectacular if you could also provide the Parts Express part numbers.
I realize this is no small task, and I would GREATLY appreciate the help. In return, if you need any graphics work done I'd be happy to help you out...I'm very good in photoshop.
