They look fantastic and great choice of drivers! Thanks it was a lot of work, it took me about 1.5 years to make and it is almost all made of birch plywood with American walnut veneer. As you can see it is a d’apolito configuration with 15cm paper cone mid/bass divers and a beryllium dome tweeter. I chose this configuration for its point source characteristics. The only thing you do not see very often is that I can time align it. So I can tilt the two mid cabinets closer or away from the tweeter cabinet. The bass is a closed cabinet with a 3,5 cm wall thickness and internal bracing. The driver is an 10” AudioTechnology flex unit optimized for a closed cabinet and a sandwich cone. All this is cost me about 5000 euro in parts and really a lot of man hours. https://www.scan-speak.dk/product-families/fam-illuminator/?single_prod_id=97 https://www.scan-speak.dk/product-families/fam-illuminator/?single_prod_id=195 http://www.audiotechnology.dk/iz.asp?id=4|a|933||| Confused and Middy 1 1 Meitner ma1 v2 dac, Sovereign preamp and power amp, DIY speakers, scan speak illuminator.

Mine also used to like to lie right next to my subs. Cats are bassheads, no doubt about it! It’s the best part. Mine do that too. 32 minutes ago, Mordikai said: Where are you crossing these over? Looks like it's all passive? Are you biamping? What is the f3 of the Audio Tech driver? Sorry for all the questions but diy speakers and class A amps are my thing. You made a lot of good choices, well done! Yes for now the crossover is all passive, crossing at 2.3 kHz and 300 Hz but I am thinking about making the woofers active with mono 500w ncore plateamps. Not sure what the -3db point of the woofer is. I measured and calibrated the speakers first in my living room checked everything in a good size anechoic chamber but those kind of frequencies are difficult to measure consistently so I am sure.
