MTH-30

STACKING QUESTIONS:
Ok all the smart guys out there. does it get better if the horns are coulped like the photo i have drawn (mspaint)?

or would they better benifit with the driver near the ground, or up. Height is not my concern, just wondering what is the best approach

afaik tapped horns do not couple like a front loaded horn. so there's nothing to be gained by stacking them a particular way

So should the mouth open near the floor, as to use the floor as a horn extension?

I would think that lining multiple cabinets up with the mouth close to the floor would give the best coupling taking full advantage of the 2PI space.

The PD 12sb30 has a good Xmax for a tapped horn (7mm) and according to hornresp will reach x-max at about 46Volts which is 265W at 8 ohms.
No one has mentioned that you will need a hi pass filter and it will probably be to be at least 40hz.

I use these drivers www.cheaplights.com/cart/page81.html (the first 12" on the page) they are Cheap, work great and are very similar to the Radian 2312s. I do not use a high pass. these cabs are rather great, allowing a hell of a sound that one man can set up. I Use two currently and may build two more, but my Servodrives want to get out and see action as well and i must divert the funds to repair a few of them.

would the eminence lab 12 work in this design?cheersryan
