I think I'd rather take some beaming than 20% distortion from the tweeter. Overall, I decided to go wit ha 1.9khz crossover to get the horn firmly out of it's high distortion zone. It's easy to run the scroll wheel on the mouse until you have $50+ caps lol.

I may play with it later and see if I can get the costs down. I think the crossover you posted would cost significantly more. I made sure to use poly caps, air cores with low resistance on the woofer, and mills resistors on the tweeter. I was able to get that with about $150 in parts for both speakers. I suspect the 350hz null is some standing wave, but the rock wool had little effect on it. I don't a miter / table saw and I've not been out to get any wood, so that's up next, eventually.

Why would tick 'minimum phase' when I was able to get correct agreement in software to measured results? Truth be told, I don't much understand that function in the software.įor sure. Those impedance wiggles at 160 and 400Hz indicate some resonances might be leftover. Side note, I would try adding some extra bracing inside the cabinet, and kilmat sound deadening to the basket of the woofer and passive radiator. Not that it makes a huge difference, just 1-2dB in the crossover region. I did select minimum phase for the measurements, which seems to have helped, now the phase data looks more like what I expect when measuring speakers with a fixed mic on a rotating platform. Impedance is also smoothed a bit, but in practice that doesn't really matter. The scaling isn't quite the same, but the primary difference is rolling off the woofer more aggressively, to manage the cone breakup, and therefore distortion. Learned it the hard way with my first build when I tried to be cheap and ended up costing myself $30 extra just fixing it. Good crossovers cost a decent amount, just an unfortunate reality.

If you get the alignment correct, it should look like this, which matches perfect with my measurements Woofer is 203mm below the horn (center to center) I need to determine the significance of it since 2khz is where the horn clears up in distortion, so it's a good crossing point. I have a design for a cross at 2khz that seems Okay, but I know that beaming starts at about 1800hz on a 10". I can't find my protractor, so I've not done off axis measurements yet. I'm probably looking at $50+ for each speaker for a new crossover, maybe more using reasonably priced parts. I'd like to keep the crossover values as low as I can to save money.
