Don't bother, the mass corner on that driver is only 300hz.

The horn in the JBL4560/Altec A7 only starts really working above about 200hz, and the best driver available is the JBL 2220 series, useable to 500hz in those designs.

The 4560/A7 boxes are not well suited to modern needs, they are too big for what they can do.

Best use of 4560/A7 type cabinets (EV TL5050's on the bottom).

Redesign for a 12 and take a chainsaw to the un-needed parts of the 4560/A7 and this is what it looks like (horn is the same size as the horn portion of the 4560/A7).

Redesign for a pair of 12's, better sounding but bigger (horn is same size as the horn portion of the JBL 4550/Altec A4)

The 4550/A4 was really too big (48"W x 34.5"H), so I redesigned it to work better.

Terrible photo of new dual 12 mid horn, 30"W x 40"H.

CoePA-2009.jpg

Old PA with stacked single 12 type 4560/A7 sized horns.

I have plans for the new dual 12 mid horn, a pretty easy build. They require either a JBL 2202, EV 12L, or B&C 12PE32 to work the best.

Looks great, but can't touch the newer designs.

A Quad V12 semi-horn mid cabinet, good to 800hz or so. A 15" version would also be possible, good to 600hz or so.

These can be in the range of 106dB~107dB/2.83V/1M down to 100hz to so.
