lemonhaze,
I smiled when I read you comments about the importance of the crossover being so important and laughed when you recommended the Altec Model 19. So I accept your statement that great minds think alike!
The cabinet houses only the woofer and a slightly taller and smaller version of the ALtec 620 cabinet.
My crossover is the Zilch Z-19. As you know, he separated the woofer in the circuit since it didn’t need the L-pads. That crossover is mounted in the cabinet with proved cap and inductor. The HF portion is outside so I could try different capacitors. Started with affordable Solen PB-MKP’s to figure out a layout and in case I messed something up. Sounded impressive. Coincidentally, today I finished a new HF crossover build using Jantzen Superior Z-caps and Mill resistors and the improvement - to my ears and for what I was looking for - was very rewarding.
As you know, Zilch was the mastermind behind the Econowave. His posts were very helpful throughout my DIY project. What speakers are you running theses days?
chorus,
So if you go the DIY route, look up some of Zilch’s posts for general build insights, regardless of what speaker design you go with. And if you decide, now or later, to build a high sensitivity speaker with it life-like dynamics, (and ability to tame the highs with the right gear), you could build a set of Klipsch Chorus for your name’s sake.
Enjoy the music.
