Single small cap on waveguide type tweeter response?
I have heard of using a single small cap on a tweeter with a waveguide/horn boosted response to flatten the response and create a natural crossover point. I'm playing around with the idea with the $5 buyout tweeter. Wondering if there are caveots that I'm not thinking of? I'm thinking phase will be the elephant in the room.
I took the response and gave it a tilt. This would have a nice natural crossover point ~2.4khz. Though this is not realistic as it assumes a flat slope. Guessing I'd be looking at more around 2.8khz. Planning to try a small build so small/compact crossover would be nice. Just wondering if I'm chasing my tail before I commit to making any sawdust.
[EDIT] Id put a parallel resistor to knock down the db and resonance.

Looks interesting. As long as the tw can handle the 1st order HP lower-ranges.

Thanks. Based on the lack of other response I guess this was a dumb question.
I've got some .18cf flat packs that are perfect for 830855s that I have a pile of. I'm checking out the cheap tweeters I've got to do a fun quick build. Unfortunately the techtonic units I made little enclosures for are too large to fit both drivers on the baffle or I'd just do that. The small woofer should limit the total output capability anyway so I may be able to get away with less tweeter control. Guess I've just got to try and see
Not a dumb question at all.
Oah well. I decided to use some SB21RDCs I got a while ago on sale. I figure you guys would be more interested in that combo. Maybe use some fancy veneer and try my hand at a guitar grade french polish... I picked up some pummice powder to try the grain filling technique.
