....make enough space for the woofer to be used ;-P
is 9mm enough clearance from woofer magnet to the horn baffle? hopefully in real life there will be that much,i think il route it otherwise. -or perhaps i should optimise it further to use up that last few mm :-)
i think il have to redo this one with 25mm MDF where possible
not long now left with CAD work for this 40hz beastie!!
I've seen stuff done before where there is little clearance between the magnet and the wall behind it.
If the driver does not have a vented magnet, then it could probably be used OK. But if it has got a vented magnet then I'd suggest keeping more room because that air really can come out pretty quick from that hole, and if its restricted then it could cause the motor to heat more quickly. Also the air can 'bounce' off the wall behind it and back through the air vent and cause interferance with its operation if the clearance is very little and if the driver is used at high diaphram travel. Try putting your hand over the vent on your 2226's magnet, then turn it up high and you will see what I mean, you'll hear it actually.

After you build these, you'll have more trouble than woofer clearance or magnet venting. You'll have trouble with the structural integrity of your home!!!
Seriously.
That's a cool design with a great response curve. I assume that you've entered π/2 (eighth space) in Hornresp, yes?
Adrian makes a great point, similar to the cooling vent comments from Adam last week. My gut feeling is that the distance combined with the deflection angle of the boundary will probably encourage venting. One thing is for sure - Your response curve looks great and I expect these to sound great too.
