As I posted on the review for the Snell THX system (which appears to use the same Sub 1800), I assume that the Sub's response of "17Hz–80Hz ±2dB" is due to an internal crossover within the Sub? The external crossover does not seem to cover the sub(s), and I double the 18" driver has nature HF fade that matches exactly with the rest of the system. Thanks.

The Snell Reference A5 speaker system comes with THREE crossovers - an electronic active one that splits frequencies between bass / mid+treble and sits between the pre and power amps, and an external passive one for each speaker that is, in itself, a damn heavy piece of kit.

As a note of cynical irony, I bought an unused pair of a5 towers, the bass x-over, the passive crossovers, then I got M.E. I now have a complete collection of audio equipment I can't lift :P

I didn't buy the subwoofers. I wish I had, but reality says that I really don't have an environment that will allow me to put a pair of subwoofers with 3' cabinets in it! Instead I've sourced some custom passive custom BK units, and I'm using a configurable active crossover with room correction to allow me to dial-in the setup.

If I am reading your comments correctly, the subwoofer by itself is just a driver-in-a-cabinet design, without any crossover. If that is so, do you by chance remember the specs of the subwoofer driver? In particular how high can it go? Asking because I am actually considering a compression driver + horn design for the upper frequencies, but it can only reach down to 400-500hz. I would like to avoid a midrange woofer to the extent possible.
