Also try Anne Bisson's "September in Montreal" for demo'ing speakers. Get the high rez download - it is really good, and perhaps one of the best examples of superb mastering at its best. It is wide dynamic range stuff with infrasonic content so not all speakers will do it well.

If you want to check to see how "transient perfect" a multi-way speaker is, try live recorded jazz like Chick Corea's Trio "The Song is You". Most single driver full range speakers will be close to transient perfect but don't have the bass authority to reproduce kick drums well. If speakers are transient perfect, the drums, bass, and piano sound like you are there in the club.

BTW. The Pidgeon "Spanish Harlem" is on the Chesky "The Ultimate Demonstration Disc". Well worth having. There is a lot of good stuff on that CD. It's also on "The Raven" if you really like Pidgeon. None of the other tracks are recorded with any where near the fake ambiance used on "Spanish Harlem"

Why use 'wonderfull' recordings.. that's just Self stroking.
Or more charitably proving how "good" your setup is on a known good recording. Not much accomplishment in that Me thinks.
Torture Test by trying one that's genuinely difficult to reproduce adequately 😉
IE: PJ Harvey recordings ... pick one.
On a less than capable Setup her voice sounds like a cat with a stepped on tail.. shrill harsh and congested, definitely an aquired taste / sound.
On a system capable of deciphering all the compression and recording oddities.. her voice is Surprisingly good, pleasant even.
Hear her well, then you definitely have done something right.

The plastic frames are definitly superior sonically to the stamped metal. They are not without their issues thou. The new "plastic" frames seem even better. Prototypes only seen, developed because of user feedback. Harder & more expensive to make, but that doesn't seem to deter Mark.

Very close to the footprint of a Fostex FE12x, so more like a 4.5" driver in termsof bezel size.

Well honestly, until we could conduct a double blind, placebo controlled ABX comparison between two versions with the exact same "drive train" and emitting surface -as Mark might describe them- it might only be conjecture as to which frame design is demonstrably superior. 😉
Bob - that's probably sarcasm - although I can't always tell with my own 😀
What I think would not be in contention is that most builders would likely welcome any version that doesn't require countersunk / rebated mounting hole for flush mounting - of course with the shallow cone profiles of most of Mark's designs, that generally means a chamfer / roundover required on the rear side of driver cut-out.

Then there's always the chance that the most accurate and resolving system and high definition recordings in the world couldn't get you over a dislike for a performer - first that comes to mind is most thrash metal I've heard, followed not far behind by the likes of Yanni and Blossom Dearie.

I bought the CHN70 knowing it is a low cost driver - of course it could be a diamond in the rough but I had no intention of it being a perfect speaker - the goal is to make it sound pleasing care heck whether it measures straight or not. I don't see any point in wondering about a plastic frame or other goodies - just go buy the A7 for that. Of course I'm doing all this backwards as I've spent years refining my ability to design and build a great sounding SS amp and I've built several speakers as well as owning some nice PMCs. Now I'm going back to play with the simple stuff 🙂
After not really being able to listen to the CHN70 in an open faced speaker - I am finding that it sounds quite nice sitting behind a Karlson aperture in the Karsonator. The balance is just about right and overall presentation is now a listenable, and even enjoyable. I think if you can get over the looks of the Karlsonator, or just cover it with grill cloth, it may just be the perfect enclosure for it. No where else will you find a passive ability to acoustically shape the 600Hz to 7kHz plateau out.
is there a substitute which will drop into the PA130 XKi? - my kutter just completed a pair - they get a clear coat next http://i.imgur.com/cV7Izex.jpg
he charges very little - ask him for a quote for whatever you'd like - btw - it takes not much more labor if any to assemble a large cabinet than a little so consider that factor

I'm very impressed indeed, I know nothing of this type of enclosure but it has proven itself in your hands.
Before I look at building a new enclosure I'm going to finish building-out my spud amp - it may offer the sound I want in the current enclosure on account that the amplifier has been designed with a frequency-dependent output impedance that sounds like it may match well with this type of driver.
Could I add a piece of wood with slot in it over the top of the existing Oaken enclosure and achieve the same ?
Possibly, but most likely that is too close to driver and you will get cancellations at HF's and mid range where shaping needs to occur passes through unscathed. Cut a piece of cardboard or foam core or thin ply with a K aperture and place in front of driver and have a listen. The Onken won't have the same big bass as the K'nator so will probably need a BSC.
besides a shallow K-cavity & aperture made of cardboard or foam, you might try JBL's version of the old dispersion lens trick - wonder how well if might work for a modern RJ speaker -? can elements of the Karlsonator be used in a RJ variant to gain a bit in the bass?
can the RJ scheme improve cone control vs a direct radiator?
slimline RJ-12 - the RJ speaker comes from ~1951 - same year as K15 was developed
