Anyone know anything about these

looking for driver specs, not sure what is in there.
Really interested in the mid part of this, was wondering if anyone had any experience with these[attachment=0:eqcpknhi]<!-- ia0 -->maybe.jpg<!-- ia0 -->[/attachment:eqcpknhi]

That looks similar to Steve_B's design. If you haven't seen it check out www.burton-manor.co.uk/Audio/HCLA.htm , and read the whole site while you are there.

Renkus-Heinz also used a similar co-entrant mid/hf design in one of their products, I can't remember which.

The mid drivers need to be suitable for a horn ie light cone, strong motor, high resonant frequency. Ciare 6.38mr3 or 18sound 6nd410 spring to mind here.

The first plan appears to use two (10 inch?) drivers in bandpass enclosures for the low frequency, whilst the second is a sealed box.

nice site, guy seems to be very intelligent.
I was hoping they were for 12" mids.
