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.

Guys, I bought 2 pairs of these awesome drivers and I am using one pair for my home stereo. I was going to use the second pair for another project I started but I have too much going on. I thought I would offer you guys first chance at a pair of lightly used N314X, delivered to the lower 48 for $600.

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

I have had plenty of OCD issues with this two way. I would need therapy if tried a three way again. 😳

What Edgar said 🤓. I talked to eminence about Re value at 1k mounted to a horn to get close.

Zobel: 6 ohm resistor and 36uf cap across (parallel) the inputs of the N314x. L Pad is https://www.parts-express.com/speaker-l-pad-attenuator-50w-mono-3-8-shaft-8-ohm--260-252

Yes!!!! Zobel is effective. I use it with an l pad too.

More experimentation; I think a zobel is worthwhile with this driver. I’m still experimenting but I can hear a difference and I think it’s good.

Wow. Good job on restoring those!
