In a bind

The manifold is done (well, except for the top plate, but that'll be glued on today). I've cut the 2x4 base which will mount to the existing rafters, but haven't attached it yet. I'm wondering if I should spread the load across more than two rafters? We're talking 80# of drivers plus 50# in the manifold itself... I think I'll just tie the rafters together with some 2x4 to help balance the load.


I've decided to do a reversed and standard speakermount to make the manifold more compact up in the attic space. What this means is that one of the speakers will have its (+) and (-) the opposite of the other, so that when one moves 'forward', the other moves 'back'. The net result is that both move 'in' to the center of the manifold.

Because of the large power needs for drivers this size, I'm really considering having a speakon connector bringing the power up to it. The EP2500 already has a speakon output which can send up both channels. I could install a speakon jack at the manifold and wire from there.
At the manifold, there's a second issue, which is that I need to get one pair of wires to the inside of the carefully-sealed box. I was thinking of using speaker binding posts, but they need to go through 1.5" of MDF, so I may just drill a tight hole and thread the wires through it.

I'll head to the speaker store today to see if they have the neutrik connectors.
