That spike might also be due diffractions, which is normal for a coaxial. But the 12C362 does behave very well for a coax.
One thing it does really well is imaging. On this ECM recording of Colin Vallon it can spot the precise point of impact of drumstick on a ride cymbal, then draw the cymbal vibrating around the impact point in almost lifelike size. And the tone is very realistic also.

Problem is that I've built some little 2ways using a £20 5" mid-woofer and except for the bass response it is sadly beating my 12" Tannoys in every way.
Seems pointless having them especially since I don't feed them anything below 250Hz.
Conceivably I could shrink my speakers from a 45L and a 140L cab to a single 90L one with different bass loading.

Are you using a waveguide on the dome? The little lsr305 does everything right except dynamics...unless it's enough for the setting.
I love my coaxials, but I do wonder what the same compression driver would sound like on an optimized waveguide.
Nice read, clever project...
Well, at least I hope it'll be clever. We'll see.
I'm using 12" Tannoys over Volt 3143 in a t/l right now.
After using a Faital 5FE200 to build some cheap passive nearfields for my daughter I'm considering replacing the Tannoys with either BMS 5S117 and a wave-guided dome-type thing (likely to be either XT25BG60 or Scan D2608) or the BMS 5C150 co-axial and putting the Volt in a smaller BR cab.
As I said I'm a bit concerned about the 5dB spike at 18k they show on their site.
I'm analogue active so no DSP but ideally I would like to get rid of the parametric eq that is currently flattening the Tannoy tweeter. It's an old pepperpot one that needs a bit of massaging.
A co-axial would be nice because that way I can use the speakers in either portrait or landscape orientation without having to build a movable sub-baffle as I would with a wave-guided dome.
Haven't got enough spare cash at the moment to just suck it up, buy both options and see.
Budget always gets in the way. If you do a two-way the Seas dxt is a nice option as well. I heard it crossed at 1.6k. Sounded great. An all BMS build would be fun using that little waveguide they have.
In the spirit of the thread. Here's some new Martin developments to speculate over.

Probably cost prohibitive for overseas but diysoundgroup has some really nice coax kits. The alpha model is a custom unit that seems to perform very well.

low frequency music
Hi there AC: You are correct for pipe organ music (16 Hz), however, the lowest note on the piano is 27 Hz. Often you hear people say there is nothing in music below 40 HZ, so a lot of speaker enclosure designs are missing the low end of orchestral instruments (look this up via google). If you only listen to rock, where the most electric bass instruments have limited low frequency capability, then 40 Hz will do. ...regards, Michael

Definitely unique. I think I even see some foam in the throat on the larger models. Directivity is waveguide smooth if the charts are to be believed.
Martin has been coming up with some very Innovative products. Might have to give in and order one to try out.
This is true. And I do listen to a lot of piano music. The simulations suggest that output will be ~10-12dB down at the lowest piano note, so even given room boost they're going to end up being attenuated.
But this is sadly almost a given thing. Given that I'm after a simple 2-way coaxial solution, I'm going to have to accept compromise. I'm not after perfect here, good enough will suffice.
Haven't used proaudiowebshop but I have used Lean Business (Lean Business - Outstanding Audio, Guitar Speakers and PA Speakers specialist) who have been exemplary in all my dealings with them.
Can't see that particular driver on their site right now but it might be worthwhile to contact them.
As for 16Hz organs: They exist but are rare. Almost as rare as pieces of music which actually utilize these capabilities.

My 4552nd's have that as well. Diaphragm break-up? I notch it out but tbh I don't notice it.
I'm not sure whether it's breakup or what, but apparently from what I've heard it's intentional, done to help the response reach up to 20kHz.
With a crossover even the 12C362 does exhibit some of that behaviour, but not much. It's a subtle hump around 18kHz of something like 3 or 4dB. Quite inoffensive, only giving slight tizz on some rare recordings. At least it doesn't bother me, so I've decided not to try erasing it. And it doesn't show up on the off-axis response.
I've also tried a 4544 in an Eminence Beta10CX, and it didn't show this peaking behaviour.
