Okay. Going modular. Thanks for reminding me about juxtapositioning the tweet and mid.One box for the 2226, another for the 2123 and tweeter.
It didn't occur to me until after I did the design and cut the plywood but the big box is proportioned very much like the 3677 box.
Gonna start with the Vifa 'cause it's on hand and then try the Morel MDT-37 horn-loaded as soon as I have the funds.
I ordered 6.2uF Obbligato oilers and 2.2uF Obbligato aluminum foil for the 3500Hz tweeter cross. 6mH Erse for the 2226. All the X-over components on the outside so I can play with'm.
Should I try a small value resistor across the tweeter terminals?
