Yes I have...first off why 2-15's? The rig I built has 4-10's and 1-15. I also have another 15 cab just for good luck. That way you can have the best of both worlds, tons of punch and tons of bottom end. Rattle your pant legs!!!
Parts express carries drivers and also gives thiel/small(sp?) parameters which will help in your design and projected freq response.
You will need the parameters for loading at ishtek and also be able to transpose between
metric and standard inch sizing.
PS If you have the speakers and not the parameters try finding them on the web through the company
