I built the ZRT's finishing them about a year ago. I bought the drivers and crossover from Madisound. For the cabinets, I bought the
Denovo Audio Knock-Down 1.16 cu. ft. tower cabinets from Parts Express because I don't have table saw. The Denovo cabinets are bit smaller than the Zaph spec, (1.33 cu.ft), so I adjusted the length of the vent using Bass Box Pro.
The result is great. I replace Magneplanar MG 1.6QR's with no regret. The ZRT as slightly more detailed with slightly better articulated bass, (IMO).
I can't say I agree with the negative comment about bass dynamics. I find these very good. I drive the speakers with a Pass Labs X150.5 and they sound terrific.
I doubt you could find better commercially made speakers for 2-3 time the cost of DIY.
