Can anyone make any recommendations on a DIY speaker project or kit that will make a good match for a Zen. My hopes were to find an existing design or a kit with the following characteristics: 2-way, MTM or TM, simple box construction (ie no TL design), >92 dB, 8 ohm nominal for around $500, but the beast doesn't seem to exist.
Thanks for any info.

None of these are run-of-the-mill suggestions:
What about the Adire Audio HE10.1? The T & the M are closer than usual, BR box, 95 dB efficient, quite a bit less than $500 ($300).
For nominal 8 ohms any MTM will require 2 4 ohm in series - hard to find -- or 2 16 ohm in parallel which may well be harder yet to find.
Another would be a Fostex FE168S + a T. You can put it in a BR and the tweeter really only needs be a superT (if you find you need one at all)
And what about taking a design for an MT, that has a T that is padded down at least 3 dB, then use 4 Ms (MTM+MM on the front) to get 6 dB more level and any further gain by not having to deal with bafflestep loss. You can do it bipolar or as a 2.5 way. The Adire Kit 81 is a possible example (i was at their website -- an easy one to grab). Plus Adire would probably be helpful with getting the XO mods right.

high efficiency
www.zalytron.com under "high efficiency" has some kits you might like. I don't know if any would fit you bill exactly or convince you to compromise one parameter a little.

diy speakers: horns, perhaps?
I have had excellent results with the diy horns on my web site:
high frequency horns
bass horn

The Zens work better with low impedance speaks - they deliver more (badly needed) power that way. 12ohm speakers are not the best match. The Parker Audio 95's are a 2 Ohm speaker designed specifically for the Zens and preliminary reports/opinions are very good. I believe the have a 30 day money back trial/guarantee.
Just a thought...
When looking for speakers for low power amps, as well as looking at the sensitivity, you also need to look at the load impedance graph. A speaker that looks relatively effecient on specs, can have an impedance response that swings all over the place, and this will challenge low powered amps.

As "pinkmouse" has stated a impedance plot of the speaker would be a very useful tool in speaker selection. In addition... a responce plot/graph would be very useful in accessing the speaker responce in terms of flatness. It is not uncommon to plot a speaker and find that it has hot spots at crossover or unusual peaks or valleys.
