Ribbon Tweeter Crossover Question

[RedJacket]

Let's say I have a Ribbon Tweeter that has a recommended crossover of 4th order L-R at 2800 Hz. If the manufacturer of the Ribbon Tweeter is able to lower the crossover frequency to maybe 1000 Hz, how would that affect the choice of Crossover? Would it still be a 4th order L-R?

Trying to understand the relationship between Driver, crossover frequency, and crossover characteristic.

The first hypothetical of a 4th order at 2800 Hz sounds very much like the RAAL 10D. The RAAL OEM 20 has a recommended crossover exactly 1000 Hz lower, and it's a LR 4th order acoustic. Ribbons need to be crossed with a high order acoustic slope. Less steep slopes will introduce very high harmonic distortion at the low end.

Only the manufacturer of said tweeter can answer that question quite frankly. 4th order is very steep, so in essence the roll off will drop like a stone. Going from almost 3K to 1K is pretty significant for a tweeter though, so I don't know how realistic your scenario is. Are you asking something purely hypothetically?

Edit: never mind, Dennis responded already.
