Planning ahead for next winter, if other problems would clear. - I've been looking for high efficiency speakers, probably some sort of horn combo, and came across the Bastanis horns. Down firing rear loaded bass horns, but no info ...
anybody know what they are ?? Some version of inverted BIBs or Voigts ???

This?
I'd guess that's a single-fold "back-loaded horn". The extra lower mids coming out of the bottom probably crudely balance the rising directly-radiated response of the unfiltered 15"...

That's the Matterhorn, - exactly the one I was looking at. Thanks for the response.
I see there are lots of other lookers, too, so maybe I should clarify a bit..... What I've been looking for is a high efficiency design with a fair bass extension and good dynamics. I've always wanted to build a horn speaker, but most are either way too large or have too high lower f's to my liking. I'd prefer not to use a sub. I know these are somewhat contradictory terms, but then there's always compromises...
That's why I've been looking for a decent HE bass/mid, to eventually be combined with a good tweeter or horn in the treble....

i dont know much of the science behind backloaded horns, but i think its fair to say there is very little "horn" in this speaker. bass will generely be omni directional, like any other box speaker.
i have listened to a couple of his "designs", dragonfly and little big fun and found them pretty bad actually.. promises of how they sounded didnt fit at all.
terrible off-axis, random on-axis frequency response with breakup distortion from the woofer.
frequencies stand out and imaging was pretty poor.
usually speakers are designed with common accepted knowledge and physics. these dont apply in my opinion with no crossover..
utilizing 10-15 inch woofer to 5-6khz doesnt make any sense imo.
he believes crossovers color the sound, when a huge contributor to that is poor dispersion, which he doesnt mention at all.
a cheaper kit with an actual horn and crossover:

I wasn't actually planning to copy the Matterhorn, rather to look into a possible design....
There are several designs out there which are HE, based on some usually pro 12-15'' which hands over to another horn around 500Hz or thereabouts..
I've actually looked at the Cornscala, but good looks is not exactly it's forte... 🙂

the Dragonfly IIRC was an 18" related to Eminence's Sigma with an APT50 nestled on the pole-piece. I think the boundary loaed BVR/MLTL Matterhorn size would be ok within the limitations of the small cabinet with the right drivers - you might use a coax, or woofer + waveguide - or just a flat baffle with a compression driver as long as the cd isn't strained,
dragonfly had a beta 8-cx coated with snakeoil.
bastanis internals look the same as a past german manufacturer, impulse h6?
A beautiful loudspeaker, this Bastanis Matterhorn. And best of all, it is also available for the DIY loudspeakerbuilder. - Audio-Creative

I have spent extensive time with Bastani's compression driver/horn combo. I am not favorably impressed. Many different amps, etc... YMMV.

OK -thanks,guys...... that sketch of the interior, - somewhat like what I imagined.....maybe I'll have to continue my search....
Some years ago, I was set to build something liek Bert Doppenbergs Reference / Oris combo, - but then I've always fancied a horn setup, and as this will likely be my last larger build....

Otoh, the measured response from his 12" driver was fairly amazingly fantastically flat when measured, out to 5kHz!
Whatever he did to what looks like a fairly ordinary paper driver, the treatment, actually works.

The construction can be defined most precisely as BVR (Big Vent Reflex).
Its behavior is closer to the bass-reflex rather than to a veritable back-loaded horn.
My experience with BVR shows, that precision of the contour is extremely critical for bass reproduction and it is not recommended to be divided to linear section like the discussed construction.
The mouth area is too large at a glance, but I cannot say more without the T/S parameters of the bass driver...
Heard them. Brilliant!
Not easy to create your own though. Did some extensive research on the drivers used, but cant seem to find which drivers these are...
