Any news on a Klipsch demo of the new subs at Axpona this coming weekend in Chicago?

The size, of the 4, should be selected by output and performance.  There is not a recommended La Scala match, but I'll pick Large.  You will not want or need additional subwoofers for any reason.  If I were you, I'd replace any direct radiator subwoofers you have with these.  They are easily special effects capable.  You will not regret it!  We were given impressive response curves and told a lot about the physics of the subs, that i won't discuss.  The Medium goes deep enough for any music, the Large should cover most LFE effects, if not all and the XL is likely brown note capable.  😆  Choose the additional subs for the max dB output you require.   They are powered, so you will not need an additional amp.  The amplifier power is surprisingly low and the embedded amp allows some control of distortion. 

 

We were not given a release date, but speculation was not before Spring/Summer '24.  You have plenty of time to try to time the Market. 

 

This is the Large.

 

What's with the Name Tag ya old Coot ??

Can't remember who You are ??  ,,,😀😀😀

That active LS system with new horns at Subfest will be launched this year and the last Pre-Production Beta has been offered to the Museum. The Museum is going to give them away as part of a Spring Klipsch Museum Visitor Campaign. Click link above for more information.

Four sizes, @billybob, as advertised. From what I understand you are correct. They don't even have names yet. I believe at the class they were referred to (smallest to largest) as 1, 2, 3 and 4. (I could have that backasswards). I have yet to hear someone call them "sm, med. lg, and xl" and I think that was intentional as none of them are "small"

 

They are horn-loaded so they can't be "small" 24 x 24 x24" for example because it defeats the purpose of horn-loaded bass, which is ultra-low (non-existent) FMD and IMD). PWK's life's work, and what earned him an AES Silver Medal wasn't just low "distortion" it was the study of IMD/FMD on the subjective evaluation and preference of loudspeakers. Beers identified it in the 40's, PWK, like all things he dove into, figured out a way to better measure it, isolate it, and minimize it. 

 

I believe it's a matter of physics, these guys can talk about it more, the way to smush it down to nothing, per PWK, is to keep that cone from flapping so much. 

 

They learned all of this is in the class and I'm sure that will be reporting on this further.

 

I'm hoping we can do a repeat, mini version of this class in March in conjunction with the PWK BDay Bash. 

Fairly certain billybob was referring to the relative size between the 4 to denote the small. Certain many still hoping to learn more, since an acquisition mentioned recently.

Thanks!
