Take xlim off the table. You don't want to fool with approaching it. Always limit to Pe or xmax, whichever is lower. With the 3015LF they're the same. Understood. Thank you. Grant, nicely put :cowboy: . The theory in the parts you copied from Wikipedia I already knew; I assumed they were quite comm...
You mean both average Pe and Xlim...are at the same voltage limit? They are. Most drivers have an Xlim voltage well below Pe, the 3015LF does not. Hold on, I think some terms are getting a little mixed up for me now :conf: . Before I loose track: With Xmax I meant maximum linear excursion; 9.6 mm f...
in theory would it be safe to conclude that if the average power isn't exceeding Pe AND peaks stay below the level where Xlim/Xmech would exceeded, the driver should survive? Yes, but that limit for the 3015LF is 60v. You mean both average Pe and Xlim/Xmech are at the same voltage limit? :noob: I'm...
what is the expected maximum voltage peak that will drive the cone to just below 17 mm. You don't want to know, because that would result in a dead driver from the coil bottoming out. Now I'm confused :noob: . Isn't 'bottoming out' the same as the coil hitting the backplate? Which is not going to h...
Xmax and Pe, as the displacement and thermal power limits for the 3015LF are the same. That's what I was looking for :hyper: . Thank you. A few volts more won't result in instant destruction, but there's little to be gained with more than 60v, and much to be lost, namely the driver. Agreed, there's...
I must say I like to discuss this kind of things on a forum like this, where contributions make sense and not just bash the OP or any other comments :clap: . You're ugly and your mother dresses you funny.... Sorry, you were just getting too comfortable..... :mrgreen: I guess I had that coming :owned:
I'm struggling now... I've tried to explain, as best I can. nick reckons I'm lecturing, so I'll just stay out of it. And I appreciate your efforts :!: I just had the idea I didn't get across what my questions were and what information I was after. That's why I kept on trying to explain. Not speakin...
Sure, but that's not at all the point of this. I know that's usually why someone will ask, but his amp isn't going to let that happen long-term even if he tried. The limiting circuitry built-in to his amp is not a brick wall, it's a bungee cord. He has the means to brick-wall limit, but is just ask...
From what I've seen here so far, the more common driver failure in Bills designs is tearing. That may suggest over excursion is the cause, as generally, voltage has been exceeded. I apologize for discussing this so extensive. I'm a nitpicker who's just trying to learn :P . If overexcursion is to bl...
It should really be pounding at 60V. It is! 8) If you are bothered by the limiter kicking in at that high of a voltage, then you probably need more cabs. One thing you don't want to do with pro cabs is exceed or come close to exceeding your maximum cab output. In pro sound, having some headroom is ...
It sounds like you're wanting someone to say you can exceed 60V. Its already been established, so why try and change it? From my understanding, the limit in these cabs is usually related to overexcursion and mechanical stress on the driver. Power compression will also probably set in severely above...
It's not safe to rely on the the amps limiter at all. My understanding is the limiter on your amp isn't a brick wall limiter as you may find in say the Crown xti series. It a protective mechanism for the amp, rather than the cabs attached to it. Agreed. It's more of a marketing term :wall: . If you...
