Since most speakers can handle short peaks exceeding their nominal rating a more powerful amp is unlikely to do harm when driven at normal levels during normal use only a few Watt are needed. Beobloke Active Member. Reiner is quite right, however of course if an amplifier that is too powerful is turned up too high for too long, then burnt-out voice coils can result, along with torn surrounds and suspensions in really extreme cases.
Londondecca's case 1 Tweeters are most susceptible to this. Speakers are more delicate than you think. Try to be gentle with them if possible - don't be tempted to use them too loud. Lostinapc Guest.

The popping means your amp is feeding DC into the speakers, so yes clipping. It's more damaging to tweeters than mids though When you look at power handling of conventional cone speakers there are two factors to take into account: Thermal power hanlding and mechnical power handling.
Thermal power handling is realistically the dirvers long term power handling in RMS. Its better on speakers with larger voice coils as they can dissapate more heat than smaller voice coils. Then you've got to consider the voice coil wire and venting, round wire isn't great as air can heat up between the windings of the voice coil. This is why a lot of manufacturers use flat and hexagonal voice coil wires. Mechanical power handling is more to do with what the driver can take for short bursts, most decent speakers will take large amoutns of power for a fraction of a second, but keep the power high and the voice coils would soon melt.
Clipping and overdriving speakers by all accounts has similar effects, the cone is still moving so the voice coil is being vented and cooled, but as a clipped 50W amp can often produce as much as W clipped then a pure W would have a similar effect to the speaker.
Basically a speaker dying means you've driven them passed their mechanical or thermal limits, if thats with a clipped or unclipped signal is doesn't make a huge difference. The advantage with clipping is that the speaker will sound terrible and make nice popping noises, so it's easier to tell that you're running clipped. It's much harder to tell that a speaker is getting too much clean power, but most home amps aren't potent enough to overdrive speakers in that way anyway.

And in terms of "They are under warranty for 3 years" just does not hold out. Acoustic Energy check all drive units to see if its a genuine fault. If it is they replace free of charge. If its not and the drive unit has been burnt out due to you turning up the bass adding distortion much quicker at lower volumes and volume too high they will charge you for a new drive unit.
Lets be honest they aint going to pay for something you have done to the speaker yourself. And as Kazman said get a sub if you are wanting more bass. I have seen that happen many times before, different recievers will push speakers harder when the equalizer is turned up full compared to others. I have the EVO 3's myself and the main problem when you have the bass up too high is that the midrange drivers begin to strain easy as they are the smallest and output the most sound.
Its hard for me to run them in stereo though as the reciever will easily take advantage and power the drivers up too much. Oh and if you tried playing a battle scene from a DVD with the sound on stereo and the bass up high then good luck cause they tend to strain even easier when its a pure 5.

The problem with EQ's is if you boost a frequency by 3db you need double the amp power at the frequencies you're boosting So if you're running your amp at near full power, boosting means you're introducing distortion and clipping. You don't need larger drivers to run loud though, I'm testing some small pods at the moment which we've developed to sound fantastic with large amounts of power, and they are efficient too Then again they're going to cost a small fortune so in general I guess larger drivers are needed.
I don't want to give too much away as they're still in development, plus I don't want to turn this into an advert as I might get in trouble.. They're about db efficient and so far have taken 75WRMS per side, and as we ran out of power we drove the amp into clipping to see what happened, no problems as yet.. You don't need to highpass them at all.. In theory they should handle wrms, but I want to try that kind of level for a sustained period before saying they can actually do it.
They're likely to be used mainly as monitor speakers, but we're hoping people might use them for home cinema too.. The website is under construction, and as soon as it's ready I'll ask the mods about posting a link to it.. Loudspeakers with a lower impedance value offer less resistance to the current. This means that they pull more power from the amplifier. If the amount of electrical resistance imposed by each device is mismatched, two negative outcomes can result: Damage to your system and distortion in the form of clipping.
Clipping occurs when more power is required from an amplifier then it is able to deliver. Once the maximum amount of power supply voltage has been reached, it becomes impossible to amplify the incoming signal without compromising its form.
This means that the signal is amplified but in a very distorted form. In technical terms, the sine output signal loses its rounded peaks and troughs. This occurs when the highest and lowest points of the sound wave are cut — or clipped — off. When the audio signal becomes distorted in this manner, not only does the sound suffer, speaker systems can be damaged by clipping. For one, since clipping is a result of an overdriven amplifier, the electronics can become overheated.
But the loudspeakers themselves can also be harmed. In fact, clipping is actually more likely to damage your speakers than your electronics. A poorly aligned speaker system consisting of high-performance loudspeakers and a weak amplifier will be especially prone to clipping. This can cause the speakers to become damaged.
