Just to have some food for tonight.

There are also designs on the 18sound and B&C web sites for double and single 18 enclosures.

How much are you thinking to spend on the boxes?

How much and what type of power are you driving those subs with Art?  And how big are the cabinets?
I might consider building one if it fits the bill.

Care to post a picture? I wouldn't minding one to try for drum fill also.

Here is a picture showing the subs, they are 26.5” wide, 22.5” depth and height.
Powered by two Crest CA9.
That was the first time I had put four in one cluster, I was expecting a ton of output Shocked .
As it turned out, the power was lame, at 50 feet I was getting less output than at 125 feet with good power,  subs on either side of stage  Mad .

Marjan,

Here is the tell all story about the top cabinets:

http://srforums.prosoundweb.com/index.php/m/389133/19717/?sr ch=Box#msg_389133

The lower top box has four 8” cones and no HF drivers, it gets the HF above heads and provides more low mid, the HF can outrun the mids without the extra box.

After using these cabinets for a few years, I have to say that the angling between cabinets and the whole stack  is absolutely critical for even HF coverage, a few degrees can make a huge difference.

The driver count: eight Lab 12, twenty eight Eminence Alpha 8, ten EV DH1Amt-16.

I’d like to carry twice as many subs, but can’t fit any more stuff in my 5x8 trailer with eight 2x8 monitors, a drum sub, amps, cords, stands, and FOH...

For a drum sub, the much higher sensitivity in the 50HZ up range of an Eminence 4015LF would be a better choice for most drummers.

One more question Art,
        Do you think the single 4015LF would have more output then the two lab subs in the ported box?

Yes and no, depends on frequency.
As I said, the 4015LF will do more in the range most drummers want.

The traces below are at the same drive level, comparing a  single 4015LF, Lab 2x12, and a single very small single Lab 12.
