Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?

@asvjerry 

Sounds doable but Heil only go down to 800Hrz  the Apollo go down to 125Hrz to cover most of the vocal range.  They custom built them which why I suspect the price. 

As soon as my baffles get built (waiting on my cousin but the labor is cheap... beer mostly)  I'm planning a OB two way using the big Heil and a 15 inch woofer. 

I'd bet Apollo has an open house that you could listen too without the rent a blonde but then  again you don't get to rent a blonde.

Hey asvjerry, I applaud your enthusiasm for AMT drivers.

The Apollos are dipoles. The $30K includes two towers, two woofer modules, woofer amplification and a Trinnov ST2 processor. We build our own AMT drivers in house. We do need to make a few dollars to keep the lights on :-)

The Apollo all AMT towers are high passed at 120Hz and can be driven by 2 watt SET amps or any other amps to very high SPLs. Don't try that with a stack of ESS Heil divers, or any other AMT for that matter. They are very good drivers though.

Please stop by in your most comfortable form. No blond or fancy car required. We are proud of our accomplishments and like to share, whether you are a buyer or not.

You wouldn’t happen to have a pair in the Northwest would ya. I wouldn’t have to rent a blonde I married one.

@arion ...Hi Mike, and I'll happily take you up on your kind offer..  At the minimum, I'll give you the shot at addicting me, and making @danager insanely jealous.... ;) 

As said here in AVL, "....it's like getting 2 birds stoned at once!" 
...but I know nothing about that sort of thing....🙄

We've an upcoming project in the TriCity area 2nd quarter this year, so that would be the likely time to Not show up in or with any form of 'rented'  device or organism.

I'll be nice, so you ought not to have me see anything that would require a NTC agreement or the like. (I'd sign one if requested, however....know the routine...)

  And I fully appreciate 'keeping the lights on'; spouse and self have our own 'beast' to keep fed.  The results are in your area, PM for locations...and other perhaps interesting bits...

The Apollos' are impressive on the pages of your website, and I'm already concerned that they will live up to and beyond my wildest exhortations to my spouse....who would have me talking soprano for bringing them home.

"Are you Insane?!  ...oh, right...that already existed....*grumble*damn*

Thanks again, and back to...

@andy2 ,,,Heils' sound Horrible by themselves....a heavy lump of 'squeeky', it's true.  If you didn't know beforehand what they Can do, you wouldn't buy them either.  But that's the case of any tweeter singing solo.... ;)

@danager that is true, 800ish is a more comfy zone to start the cross.  You can push them near 500, but they're not happy about it....
I've a pair of Polk 6" with a passive that fills that gap 'twixt Heil and woofs...with a sub for 100 and below....

Would ultimately do the same for a Heil line source. which could make my 'fever dream' above more practical in reality...

...whatever That is...open to interpretation as usual, esp. in sounds audio. 

Hi there @arion 

A'gon can be unfriendly to manufacturers so I'm glad you are here and look forward to your insights.  Pretty remarkable work to get an AMT to function that far down in the range.  Outstanding!

Best,

Erik
