***Also, the frequency range that could most benefit from going cardioid is bass, and yet it's the bass woofers that seem to be lacking rear wave.
I gotta wonder what Axiom had in mind when they made this speaker. It's... odd.
Agreed on both counts.
But Canadians seem to like their bipoles, so...
In much more exciting news on the topic of cardioid, AJ in FLA's new speakers got rave reviews at Axpona last weekend!
I wish I had the weekend off, because I would've loved to pop down and hear AJ's speakers and the KEF Blades.
AJ's speakers are closed box up top, and cardoid (John K-style U-frame, not his earlier and super-cool dipole 18 and adjustable closed-box 12) in the bass where it helps most (as you wrote). That distinguishes it from Gradient's approach in the Revolution and subsequent speakers of putting the mid in a cardoid-ish box as well.
IMO he's a nice-looking stand with some sort of ball-joint adjustment from the most exciting expensive speaker around right now.
AJ said he got requests for distribution in Finland or something like that.
Just as the Canadians seem to love their bipoles, Finns love their cardoids...
lol.
Now if he used HIS choice of amps and cable, they would all be like
"MEH"
Sad but true.
I remember a DIY get-together in ATL a few years ago, maybe 2005. AJ came up from FL with his then-babies, which were a mostly-dipole (monopole tweeter) with a 12" BMS coax and a high-quality 18" woofer powered by an M&K plate amp (surplus from ApexJr, I assume) with sufficient boost to allow the low-FS woofer to actually play fairly low. (Very deep bass output was probably in line with a good closed-box 10).
On a flea-powered triode amp lovingly and expertly hand-crafted by one of the show attendees, it still sounded better than any of the any many 7" Dayton/Seas/ScanSpeak based 2-ways did, but it was hot hot hot up top because it was designed for use with a voltage-source amp.
(Note that I wrote expertly
crafted; the design he used was not very good, because it had like half a watt and a low-z output.)
On the lowly mass-market H/K AVR that AJ brought, they were to my ears best sound of the gathering by far to my ears. He knows what he's doing when it comes to crossover design.
