Hey again guys. I have been thinking about building my own 610 now. I've learned a lot from my past two projects (412, 212), and I'm ready to do some work with 10s now. I was thinking of a few different ways to go about this whole thing. 1.) Use 6 Eminence bp102s in a sealed enclosure with a 6" or 8" mid driver for highs (even though I don't know anything about doing crossovers. HELP) Any suggestions in this department would be greatly appreciated. 2.) Using 4 Eminence bp102s and 2 b102 whizzer cones for high end so no crossover would be needed. However, I know I'd have to port the cab this way and the size would be significantly greater. 3.) Lastly would actually only be a 4x10. However, this cabinet would follow the physics of acoustics in that it would be a line array cabinet. I would have 4 bp102 drivers vertically in a line. Of all of these choices, which would you suggest? What 6"-8" driver would you suggest and at what frequency range would you cross over? Any suggestions would be considered. I'd prefer to work out as many kinks as possible BEFORE any purchases. thanks a lot! All criticisms welcome. And I already know someone is going to ask why I chose this particular driver. I like the low end it can give and the power it can handle. I figure it will give me a greater low range in a sealed cabinet even though the highs aren't that wonderful.
