You could clone it.
With DSP the XO is a piece of cake.

This is the Bullfrog "Active Kit" by the way.
The amp is modded (stripped), which is clearly visible and for the comp. driver a small German 2x10 Watt Class A amp is built into the case of the Monacor power amp. The Class A draws power from the same power supply.

In Europe the RCF CX15N351 sells for 40-50% of the price in the US.

Some Russians designed a stage-monitor using the B&C, both for passive and active use.

Another interesting coax from an Eastern European manufacturer.
In a stage monitor test, including monitors with the B&C and RCF drivers, this coax was praised for its hifi sound quality.

2.8" diaphragm in the comp. driver and the woofer facilitates fullrange applications in a big cab > last image shows the driver in 190L, Fb @ 28Hz.
Doesn't go very loud though.

Been playing with a B&C coax also....15CXN88..
Trying to add a bit of horn ala the SM-80, and port it for lower extension.

Factory directivity plot, and a pict of my effort..

Personally, I like d&b audiotechnik a lot, but it's not exactly cheap stuff.
Their M4 uses the B&C 15HCX76, albeit with d&b's own 70x50 horn.

Cool project Mark!
I bet that sub will shake the walls big time.

The directivity of the 15CXN88 isn't bad at all, given the lack of a horn.
