    *throws 2500w Orion amp in the garbage because he is wasting it on a SQ install. fml lulz

    Thanks, MOT. You're alright, I don't care what Spider Monkey says about you.

    Classified Rules

    My suggestion would be for you to contact admin since you're on the roster as an enforcer of policy and far more likely to get a response from those that own/run the place. Here's your chance to do something for the people, be a hero and improve this place. Seems like we have our priorities misplaced since we're more concerned with censoring naughty words like shit piss fuck and cunt.

    What happened to Car Audio Forum???

    These are not the Lees you are looking for. Fucking ouch, lol.

    I made a video for fun, demonstrating what I was describing earlier.

    Component Power Questions

    I was making distinctions for others that may be reading this thread, that you clearly did not pick up on. I'll make it simpler for you. Even with the proper crossover you can overdrive the tweeter and kill it. Keeping out low frequencies does not guarantee you will not blow your tweeter.

    I was also having problems with PM until I noticed every single message from a period of 9 years was in my inbox. I had to go in and empty everything. People may have to empty everything out before they can receive a new PM.

    Component Power Questions

    You can't bottom out a tweeter voice coil because of how thick the magnet is below the top plate. I put a picture below to help with this. Most tweeters have a voice coil that is the same height or slightly less than the height of the top plate. The top plate and the coil are not very tall, only a few millimeters. The voice coil former is usually much taller by comparison and on top of that is where the dome and surround junction occurs. The allowable stroke would be limited by the former height and surround width so if there's any amount of width, you can actually produce a pretty impressive physical stroke. The stroke is not always clean but if it is, you can choose between playing low frequencies (800Hz to 1500Hz) at low power levels, or playing normal frequencies (2kHz and above) with higher output and better dynamics. There are a few tweeters that can actually do both with very impressive freedom from thermal compression or IM distortion being generated from the dome moving back and forth. The ones pictured above and below are in that category. It's all in the motor and suspension, just like any other driver.

    This is false. Simply sending low frequency content to a tweeter will not cause it to die, even with a decent amount of power. I'm not saying it will sound good, the THD would be quite high if the driver is not designed for low frequency use. Yes, low frequency content can and will destroy a tweeter, especially if it's not built for it. But it's not the same thing as saying if you cross high enough you will not blow your tweeter, which is basically what you've indicated. I have video proof of a Vifa tweeter being subject to a true unfiltered 50Hz sine wave, stroking it for all it's worth. The driver suffered no damage and is still in use today. You can very easily destroy a tweeter that has been appropriately protected from low frequencies in a mechanical and thermal sense. Even if you've crossed at something as high as 5kHz at 24 dB, if you send enough content and power to the tweeter above 5k, it will still die from a thermal perspective. There's not escaping the driver's inherent ability to dissipate heat, doesn't matter how that heat is generated.

    The only direction one needs to look in to know why there could possibly be a reason for amps to sound different and have it be correlated with the science behind it, is to read up on impedance matching and current source versus voltage source. Followed by negative feedback loops, slew rate, and crossover distortion. This information, of course, should be considered with and weighed against the speakers those different amplifiers might be paired with, correctly or incorrectly. You can see where a few years of experience with widely varying equipment may be of some value for these comparisons.

    Assclowns. That's not like you at all, and please don't take any tone with this because I'm not intending any. But insulting a bunch of people you don't know and discounting their collective experiences all in one go, for the sake of conveniently propping up and perpetuating the notion that all amps do indeed sound the same? I mean, there are countless threads on this, not just one or two guys that say they can appreciate or perceive some type of difference in the presentation of amplifiers paired with speakers that haven't changed. In reading many of those threads over the years, that wasn't my takeaway at all but that's okay, you are entitled to your viewpoint the same as I am. All like-wattage amps do not perform and sound the same and it's an awfully short-sighted perspective to have in a world full of so many different designs. Even from a statistical standpoint, it just shouldn't be possible for that to be the case. RC simply "paints" competing amplifiers very close shades of white (if you will) that are so similar, telling the differences in shade would be all but impossible. Why not simply impose a single criteria to limit the power output of each like-wattage amplifier to a percentage well under clipping, and allow the amps to perform as they would otherwise? In a subjective fashion, since that's what is really being debated to begin with. Not the science of thd or other distortion measurements. Meaning, allow the character of the amp shine through. No, he white washes every and all amplifiers until they do sound essentially identical. Well, congrats on making two different amps sound the same as possible and ask people if they can tell the difference. No wonder people don't hear a difference. Any differences that would have been appreciated would have been subtle and difficult enough. And there was indeed a fellow who nailed all twelve. Because of that, RC had to go back and adjust levels to within 1/10 of a dB and run the gamut once more. Of course, the gentleman did not repeat his success and no monies were paid out. How convenient. I would imagine listening fatigue might have had a little to do with those results but I wasn't there so it's purely speculation. Like I said, I don't want to go back and forth with you on this because; 1) I respect you and allow for your viewpoint, and 2) it's a complete waste of our time because you will never convince me and thousands of others there are no differences to be heard in amplifiers. Likewise, I will never convince you that you need to spend two pennies more than is necessary to achieve a sound that is acceptable to the ears on your head. I would simply posit that our ears have different requirements. My question then, is, if all amps sound the same why don't you run the lowest grade garbage that offers the best reliability possible for the shortest money?

    I've heard differences in amps. I can even tell you why but it's irrelevant. I'm not going to get into it. There is enough content on the web for each us to simply grab copy/pasta rebuttal and we will be no better off, regardless of our respective viewpoint. I will simply state that his criteria is flawed and he will literally never need to worry about having to pay out the 10 grand. It will never happen. The fact that someone had previously nailed all twelve choices, and he went back to adjust things further until the person couldn't do it again, suggests the same. He has even changed the rules on the fly in some instances, lol. This thread contains some of the better rebuttal I've seen on the topic, FWIW, to anyone who isn't familiar. https://forum.audiogon.com/discussions/the-richard-clark-quot-all-amps-sounds-the-same-quot-test
  14. This is called cavitation. It is the result of too much power at frequencies above tuning, for the amount of airspace the driver is in. You will need to either scale back the power at those frequencies by adjusting down the low pass crossover point or by lowering the overall gain. Otherwise, you will need to shrink the volume of the enclosure to offer better damping (cone control) if you wish to continue with the current power levels. This will change tuning but you may not mind.
