Re: Cone cry from Weber speaker quote: "I have heard the term "cone cry" in reference to Celestion speakers, but I am not clear what sound that is you speak of. If you are refering to a slight crackle in the attack, then my Celestions and Oxfords both do that as they break up. If you are refering to a separate tone, a lower "difference tone " or sub harmonic note that is not the fundamental note, then my opinion is that it is almost always caused by the amp. "     Hey GouxMan, there are a couple of different things going on... What Celestion speakers are famous (infamous?) for is "edge yowl," a phenomenon which manifests itself with a (or a few) subharmonic note(s). It typically happens are considerable volume levels and when you're playing higher in the the register. I discovered this problem a long time ago, when I was playing a Boogie with a single Celestions speaker. I thought my power supply caps were probably going, but in the end... an EVM12L speaker fixed the problem. That is one of the reasons I started using EVs and never looked back.     Now, if you use Celestions in 2x12s, the effect is more subtle. If you use them in 4x12, it's barely audible. What cuases this? As I said,it takes a loud amp and the punchier and bassier the amp, the worse the problem gets. Ihave heard two theories: one is that the voice coil begins to crap out and so this funny notes appear, the other one is that it is a phasing characteristic of the Celestion speaker.     [GouxMan: for what it's worth, I didn't hear any edge yowl coming from your Celestion-loaded TH 2x12 cabinet, for example.]     However, there are other "lightweight speakers" (those being anything but EVs, JBLs or Altec-Lansing) that exhibit the same behavior, so I don't know what to thingk. For those interested, somewhere in one of the articles at the Mesa Boogie web site, they talk about "edge yowl" in Celestion speakers and mention that some people hate it, some people don't mind it at all.     For those of you fans of Robben Ford's, there is a great example of edge yowl in the "Jimmy Witherspoon Live at the Mint" CD, recorded with the RF band as backup of a few years ago. I was at the club during the show, and heard the thing in person. This is a shortly after Robben had switched from EVs to Celestions... In the first tune, especially, the guitar will sound like it's hoarse, almost like a poorly tuned radio station. That is the best example of edge yowl on record I have ever heard.     Cheers,     Gil
