The better sounding multicells i've heard(and i've only heard a few) had been carefully hand sanded to a nearly knife edge at the throat junction such that there's no surface left to reflect energy back toward the driver.
Understood, very good point. I am not using tin though, doing them in wood, should not be a problem once the delicate fin is glued in though.
