jcn3 Posted January 23, 2023 Share Posted January 23, 2023 I was lucky enough to find a beautiful pair of '76 Cornwall 1s -- walnut finish with very few scratches/dings given the age. The insides are absolutely pristine -- look like they've never been opened before. Drives are alnico K-77 (round), K-55-V, and K33-E with a B crossover. Caps are the oil can type. In reading about the B vs B-2, it seems the reason for the change to the B-2 was associated with the change from the K-77 to the K-77-M tweeter. @Deang -- I've seen comments where you prefer the B-2 crossover and recommend going to that whenever possible. Is the B-2 appropriate with the alnico K-77 tweeter? 3 Quote Link to comment Share on other sites More sharing options...
Deang Posted January 23, 2023 Share Posted January 23, 2023 You can use the Type B2 if you want to. https://community.klipsch.com/index.php?/topic/214320-type-b2-network/ 1 Quote Link to comment Share on other sites More sharing options...
