Mixing 16 ohm tweet with 8ohm woof?

[bowtie427ss]

Horns want a second order crossover, no one cap will do.

It really depends on several variables. Sometimes, you want it considerably steeper.

First order can be absolutely wonderful in a horn system. But, that requires that the rest of the speaker system's components be exceptionally well acoustically matched.

The main thing to keep in mind is that with a first order filter even at what seems a high XO point like 8000hz is that 2 full octaves below, at 2000hz that filter is only attenuating the signal by 12db, 18db at 1000hz. That's a lot of LF information and excursion for anything called a tweeter in most cases

Hi Tom,

Interesting, I’ve never heard a 16 ohm T-35 sound wonderful. I’ve tried using a first order with them at 3k to 3.5 k and it’s spitty at best. I can get them passable on a vintage system with a second order. I wouldn’t spend the money on anything steeper.
