You'll be fine. I regularly overpower the piss out of mine. It's not a bad thing.
I'm definitely just chiming in for the sake of learning. I'm not the best at conveying the thoughts in my head so I'm really using words out of context in a big wayHow does a speaker, any speaker know the difference between a clean signal and a distorted one? If the speaker is still oscillating then it's shedding heat regardless of the signal it's getting.
I see what you're saying, but I think of distortion as just that. I don't lump clipping into that because one is signal and the other is power. Related but a distorted signal is not necessarily clipped. Agreed that clipping adds power.
Ahh, the good old days of DJing with the Peavy CS amplifiers that felt like they weighed 100 pounds each. I used to run them with the VU meters bouncing into the DDT light.I wish I had the money to overpower the piss out of everything....
If you ain't flickering the clip light, you are wasting money on too much power.
Exactly. It's ALL about power and not exceeding your drivers' limits.I'm definitely just chiming in for the sake of learning. I'm not the best at conveying the thoughts in my head so I'm really using words out of context in a big way
I had read another paper sometime back, don't recall where, that stated it's crucial to keep a clean signal going to the coil. So when I refer to distortion I was trying to imply a clipped signal.
So here's where I'm getting mixed up between the two sides...A clean signal can overwhelm a coil but so can a clipped signal....is all this coming down to the same thing as always; make sure you're only feeding the speaker what it can handle and use filters as needed? That's the art of this whole thing. Balancing install needs with what you have or will have vs. what you like. Holy crap...I get burned out reading this stuff sometimes.
So what everybody is getting into is whether it's the amp's fault or not? Hrmmm. Well this is probably where I just start watching again. I haven't burned one up yet. So I'm applying something right.
Gotta love Jack Sondermeyer and his bullet proof designs! I attended two of the Peavey Advanced Sound Reinforcement 5-day seminars in Meridian Mississippi back in the 90's - got to meet and learn from all kinds of awesome engineers @ Peavey. They really do get a bad wrap IMO (sometimes they might deserve it, but only from a "cheap is good / poor musician" angle). I still despise their lack of any sub-40Hz response in most of their subs :mean: When I asked one of their PA Speaker designers why they simply cut holes in a baffle and call it a "Port", he stated the 3/4" thickness of the baffle WAS the port length!!! This was for an SP2 "Main" speaker, but still - a 3/4" long port???!!!!??? I guess it works for their relatively high f3/fb response in exchange for extra efficiency...DDT is limiting, damn good limiting at that. Beats the fuck out of Crown's ODEP... that's horrible shit.
"Max" rings a bell - it was in the mid 90's. Our regional Peavey Rep came down there with me - can't remember his name ATM. I remember Marty McCann (spelling) giving most of the lectures. Spent a lot of time in the fish bowl and auditorium jamming, tooWhile you were in Meridian did you do any partying with Max? He's a good time. I spent a bunch of time down there too. Did a LOT of peavey service and was one of the few that did mass repairs on the DPC stuff. Can still repair those damn things in my sleep.
It was not uncommon to use a "hole" for the vent. Hell, I designed an enclosure recently that never transpired that had just the same thing. Looked damn good on paper too.
Not many pro subs go much below 40, the Q-Wave stuff does now.... Not much below. Hell, the SP series subs did not get much below 50!
I worked a bit in the field development of the BWX series. Broke 4 at a time without the coil looking anything but brand new. Then they got the suspension issues worked out
Odd - I'm not sure if I agree with all of R.C.'s findings with regard to clipping and how the energy is dispersed through the octaves. He appears to be talking about clipping a single low-frequency sinewave, and is not taking into account clipping complex full-range waveforms. He seems to suggest that clipping a full-range system WILL NOT blow tweets - but we know that is not the case.Just a closing article on the subject matter for those looking for more clarity. Where I first learned about it, as I am sure many others. Sourced from A2000 tech briefs:
IMO you are misinterpreting what RC is saying. He said it is seldom the case, implying infrequent occurrence, not omission of occurrence. Likely due to his implied assumption of proper application. Nevertheless, The Rane article and JBL articles agree with exactly as what Richard's data indicated...that excessive power from an x level of clipped signal, can damage tweeters. RC just seems to assume that the tweeter will be properly applied and set up in a system, so there is no reason to experience full amp saturation.Odd - I'm not sure if I agree with all of R.C.'s findings with regard to clipping and how the energy is dispersed through the octaves.

JBL certainly states otherwise:
I dig and respect R.C. and all, but I'll believe JBL/Harmon (and my own Live Sound experience) well before some car audio buff
And even though the clipped harmonics are distributed throughout the frequency range, when you clip a sub amp that's actively crossed, ALL of this energy still goes to the Woofer's coil (the woofer has no passive x-over to filter this energy out). Plus the much higher "duty-cycle" of the clipped waveform further increases RMS Power...
I don't see how that's possible if your tweeters have proper filters in place. Again, if you are fully saturating the channels that feed your tweeters, creating an excessive clipped state, then this only seems to point to inadequate application.That makes more sense IMO. So it's mainly that the full-range amp can keep increasing the HF content's power (since it is already relatively small compared to the bass) when the user is slamming the low-frequency spectrum into clipping. As long as the woofer can handle the total RMS heat of the clipped amp (generally a max of 2x clean rated RMS power), the woofer will keep on chugging just fine (but sound like ass). That combined with the small increase in harmonics due to clipping the woofer, and your tweets are toast just as JBL mentioned above...
