Thread starter Relishh13 Start date Feb 17, Relishh13 Enthusiast. Hi, I didn't see anything like this posted but will ask. I am looking at a few specific models but don't want to end blowing the damn things if I get them.

Now if these were put with this amp wouldn't it blow the center and surrounds? Any pointers or links or anything is really appreciated. During normal listening, you are using maybe watts of that total; that power is needed to handle dynamic peaks when things get heavy, so power is a good thing to have in reserve.

If you want to get loud, then get them loud but make sure they are not distorting. Jul 9, 83 0 Mississauga Ontario. Nov 3, 0 New Jersey. Come on when you put the volume to 3 or 5 you are not giving them Watts what the hell. Only possible way is if u max out the gains And also when you set your gains according to 0 db signal lets say Nov 19, 4, 0 Mobile, Al.

Just use some common sense really. The real key is to listen out for distortion, and be gently with the amp gain. I would suggest you listen to a song that you know extremely well, down to the strike of each insturment, and listen for any unusual changes.

If it sounds bad, or funny, turn it down. Nov 29, 50 0 England. Also I ordered some focal CVX coaxials for the front. Now I thought I would buy some cheap shit 5x7 coaxials to fit in the rear of my car ford focus so I could turn the power IC in the headunit off and run all speakers off my 4 channel amp.

So do you think it would be ok to run them at 95W as long as I keep the gains down? May 19, 0 philly. In my opinion there's alot of misinformation out there about the importance of matching rms ratings geared towards newbies buying cheap chain store equipment with low limits who would otherwise end up playing with more power than they know how to safely deliver. The easiest thing for the store to tell them to make sure they don't keep returning blown speakers is to match rms ratings as closely as possible.

Power ratings are arrived at using conditions completely different from what happens when you play music. The RMS rating of a speaker and the rms rating of an amp mean almost nothing when making these decisions if you take into account the fact that you can control an amplifier's power delivery and that a speaker never sees, nor does an amp deliver, ANY amount of power for more than a second or two while playing a song.

No matter how much power you're running, at any given point a speaker may be seeing as few as watts, or maybe up to half your amp's max rating at higher volumes. If you crank it regularly you may see your amp's rated output for occasional bursts during your music. Or if you tune your gain text book style and never go to your max undistorted volume and keep it there you will probably NEVER see all of the power an amp is rated for.

As long as it's clean power overheated voicecoils are not a likely problem, overdriving the speaker will probably be the bigger issue. I'd set the gains textbook style then start listening with high volume and backing off accordingly. Somebody should be along shortly to explain the mathematics of it. Personally, I'd be more comfortable with too much power than not enough. BTW, welcome to AK! Wouldn't know without listening. No reason it shouldn't, though.

If, as you say, the power amp is a good deal and it's in good working order I'd consider going ahead and buying it. Then if for some reason it doesn't float your boat, you can sell it or maybe trade for something that better suits your needs.

Messages: 38, Location: Central Missouri. I agree with the above posts. Listen to your speakers, they will tell you when you've hit the limit by sounding distorted. With that kind of power you shouldn't have to use much on the volume control. Actually, you may have a situation where the amp is so powerful that your listening range is compressed into the bottom end and it's hard to play at low volumes.

OTOH, 4 ohm speakers can be power hungry and it doesn't hurt to have some to spare. Messages: 2, I think the OP has Paradigms To the OP But as noted by several posters, there is a simple way to avoid this problem The benefit of having "excess power" lies in the fact that music has transient peaks which are significantly higher louder than the "average" loudness of the signal.

These peaks give music much of its dynamics, but they require exponentially more power from one's amp than is needed to deliver the "average" loudness of a particular recording.

If there isn't enough power in the amp to deliver these peaks, they are "clipped" that is, their tops get cut off The crest factor - the difference between the average level of your music and the peaks within it - varies by recording and genre. Ideally, one should have enough power to accommodate peaks of dB. A speaker with 84 db sensitivity will play a volume of db on watts. Your speaker choice makes all the difference in the world on how much power is required to hit the volume levels that you seek.

Timlub, I'm pretty sure you will need over watts to drive an 84 db speaker to db. I appologize, I had just run the numbers off the top of my head, but the formula is fact, not opinion, so 84 1 watt 87 2 watts watts 84db sensitivity 90 4 64 watts 93db sensitivity 93 8 I missed one line in figuring. My numbers are correct with all things being equal. In any event-The question was about having an amp that exceeded specified wattage limits the speaker manufacturer stated.

And if exceeding that predefined wattage limit would then cause harm? The answer is yes, - an amplifier rated as having wattage exceeding your speaker's capacity at full output if played "continously" would damage your speakers. BUT amplifiers typically deliver much much less wattage than full output during normal sane playback. As was already said the real problem is the sudden demand on an amp that doesn't have the "head room" to deliver the required wattage "cleanly" during short peaks or bursts in the music.

If your amp is rated as a low output amp, it will be much more likely to deliver electricity DC to the speaker which is "clipping" as mentioned.

It is this phenomena that suppsed burns up your speaker. I have also heard the limtation in the wave forms where they get cut off and demonstrate non linear highly distorted forms can also to a number on your speakers. Given a choice, I will take the bigger amp any day. You run less risk of damaging the speaker! A smaller amp, if overdriven, is how most tweeters in the world get damaged. In fact, if the tweeter is damaged in a speaker, the repair technician should always tell the user that the amplifier is under-powered.

Although the conclusions and suggestions that have been expressed in this thread are generally correct, the explanations of why tweeters are commonly damaged by underpowered amps are not. Tweeters are not damaged by DC it would be blocked from reaching them by the crossover network, if it were somehow generated in the first place , and amplifiers that are called upon to supply more power than they are capable of supplying do not output "raw electricity. That will result in the output waveform abruptly transitioning from a gradually rising or falling sinusoidal waveshape to a flat level, until later in each cycle when the signal returns to an amplitude the amp can handle.

That abrupt transition contains high frequency spectral components frequency components which are not present in the original music waveform. Since they are at high frequencies, the crossover network in the speaker routes them to the tweeter, which is therefore called upon to handle a greater amount of high frequency energy than a normal music signal would require.

That is what does the damage. Best regards, -- Al. Thanks Al, I was trying to make very general terms understandable and as much as you are generally correct. Crossovers do see DC as High frequency and do route 1st to the tweeter. This DC is raw current.

Crossovers do not block DC. In fact, Through the years, I have used circuit breakers to protect against current and have even put small light bulbs on 6x9's in cars. The kids used to think it was very cool to see them flash with the music.
