Thanks Chris. Yes, I meant eq.

Chris, I am guessing this horn would not be a good candidate for a passive crossover and an Faital Pro HF146 (or similar). Would this horn need to have an active crossover?

I suspect the sound of the diaphragm will be more important in your application. Is there a way you could try both drivers and see what you think?

I am using the 10x18 zxpc. Not much power. At my chair, about 12ft from the speakers, I sometimes get to 105 db. I would think the horns are getting less than 5 watts peak.

Randy reminded me that I had left the for sale notice in this thread. I have corrected that. They sold a long time ago. I should not have sold them. I am starting another project they would be perfect for d’oh.

I would suggest that these work best from 1k up in a two way. This led me to use a different 15” (Faital) in my two-way with a flatter response above 1khz. That worked out pretty well. I believe Dave has more hours of experience with the N314x than I do. I hear the same issues he did when he was using them crossed as low as I am.

I like the experimentation. I always thought the mids and tweets were a bit hot in my ‘78 Heresys too. Mine are definitely not 10db too hot though. Sure that’s the stock woofer? There is a thread around here describing moving the squawker and tweet down a tap (-3db) along with the corresponding cap change that always sounded interesting. An l-pad might be easier for experimentation I guess. Keep up the good work.

Those are super cool. And as others have mentioned, if you had a 16ohm mid and went to an 8 ohm you’ll need a cap and coil change on your crossover and a different autoformer setting. Those speakers should be stellar.

Can you tell how much attenuation is on the B&C with your crossover? And what is the value of the cap on the mid circuit? I’m not familiar with that crossover.

The 18x10 and 11x17 are not CD

I’m using the 3015lf_4 crossed at 500, and the zxpc 18x10 horn with a Faital ProHF146 with -12db attenuation courtesy of a 3636 autoformer with 1.2uf In front of the AF and 3.0mh in parallel with the driver. I get all the in-your-face mid presentation of my CWIIs only much more refined. I believe the speaks that avatar was selling were 4 ohms, going from memory. I’ve not used that compression driver before but you could experiment with an lpad and see if it’s a level thing.

After experimenting with a pair of these new Eminence N314x compression drivers I bought another pair for additional projects. I don’t have time for more projects. These drivers are $700 a pair new. Selling these good as new, shipped to CONUS for $600.

Dave, hope you are doing ok. Have you had time for more experimentation with this driver? The derecho that hit Iowa took the doors off my shop and damaged the roof. My OCD will have to be happy with experiments on my living room speakers for the near future. I do think you are on to something with the higher crossover point. Even at 1kHz 2nd order I think it sounds really good. Your idea of using it for a tweeter is a good one I think.

Sold

I understand exactly what you mean here. What do you think the useable low end on the N314x is?
