I've looked at this kit many times, it sells out regularly, it'll be back in stock in a few days. This kit is all Morel drivers. Driver cost alone is $700 to $800 range...
Jeff did not use any impedance compensation on this kit, that means that it will stray upwards in impedance at certain frequencies, but it won't stray lower. This is a protected Proprietary kit, they won't show schematics or curves without a purchase. I have used the parts included, they are all great sounding. I trust very few speaker designers, including some fairly well known manufactures. Jeff is a solid designer, these will sing.
