I am interested in comments on the Hiraga crossovers as well. Especially with horns other than the 1505. I was considering building a pair for my 805 horns and 828 cabs. I have spoken to a few people who have used these with the 1505 horns who liked them. And was also warned about using the less efficient 805 horns.

I have been using these speakers active biamped with HF EQ, and am worried about being underwhelmed with the Hiraga like the OP.
