DIY Speaker Kits, a good idea?

I have some homemade Magicos and melting that pile of aluminum was sort of intense but totally worth it.

I'm mid-design on a pair of 2 X 6.5" 2.5-way with a ribbon/AMT tweeter. I just got fascinated by the 2.5 way design, and the more I've dug into it, the more ingenious the 2.6 way design is. It's not a 20Hz 120dB bass monster, but rather a small to medium room design good to 40 Hz. It's been fun learning all the subtleties  of crossovers, step frequencies, and a bunch more. 

pindac,

Yes I believe Kaiser uses Pz for their bracing but not sure about baffles/side walls/top/bottom/back. Clicking the link you provided the image tells me no they do not. 

I have A/B/C tested MDF, Finnish birch, and Pz. In blind test you can distinguish a Pz cabinet over the others two quite easily. 

Without going into the many adjectives to describe Pz sonic merits the best way I can describe it is "It just sounds right". 

I have CNC machined many Pz cabinets, that the end user assembled, and despite the added cost not one has ever reached out stating they regretted using Pz. In fact the opposite is true. 

A DIYer reached out to me yesterday regarding a Linkwitz build in Pz.

From my experience having the mindset of no compromise with the objective of highest performance, you will save a lot of scratch upstream chasing cables, components, tweaks, etc...

Sure it can definitely be a good idea as well as a fun project.
