"cracking" noise When watching Music DVD's whenever the bass drum hits a very low and loud note, I hear what sounds like a "cracking" loud sound from the subwooofer. If I turn the sound down it will go away, but then it's not not loud enough for me. At softer notes, no problem. What may be the problem here?

I had set up 490 Watts pioneer speakers for my car audio system. It was working very good but suddenly one day it started making a cracking noise when high bass is played. When i reduce the volume it works fine.

My doubt here is that when it used to work fine at volumes level of 30 of 34 a day back, now i get cracking noise even when i'm playing it at volum elevel of 20. When i tried testing it, i find that speaker works fine if i touch it gently.

Could you suggest a solution for this

The sound is probably being generated by the amp; which is being overdriven.

Placing the sub at the wall/floor junction will increase bass output by 6 db. if the sub is simply a sealed box, it can also flatten the response if the driver is pointed sideways.
If it's a band pass box (ported), this may not work as well.

Your subwoofer is not capable of playing as loud as you want it to. That sound is the woofer reaching its limit. If you have any bass tone setting on your receiver set them to flat. If there are any other bass settings i.e contour, loudness boost etc turn them off. You can also try putting the woofer into a corner. This will increase the output. Closer to you would also be louder. Otherwise you need a sub with more output. Don't let the power rating fool you when you get a new one.

Im a candidate sound engineer, im strugling to set the bass drum from the mixer. how do i set it?

Bass drum by convention is ch1 on the board.
You need a good drum and a good mic

First set eq flat and pfl ch1, set gain control so drum just hits peak/or red when hit hard.

Send ch to drum group (1+2) on board, or route to master (L+R), depending on type board. Then listen to drum ONLY through the system, and adjust eq so it sounds good at low level then turn it up and keep it sounding good.
If it keeps peaking the ch then turn down gain.

There are toys (inserts) you can use noise gates and compressors if available,

Sound is objective and can not be learnt without doing it , good luck. remember good low level sound will always be better than really bad lound sound, start low make it good then make it loud.

Good drums do not need much eq. Get the drum right first.

Hope this helps

Drum not turning-very loud sound coming frm dryer when turned on

There could be multiple problems with you whirlpool dyer depending on the type of noise you are hearing. If the noise is a low grumble or loud buzzing sound this could indicate a bad motor. Which could explain you not hearing the drum turning. If however you hear a grating or grinding type noise but the drum is turning, this could indicate that something is rubbing or has become jammed inside the blower fan that circulates the air. if this is the case it too may have to be replaced. Also the drum can sometime come off the drum support rollers at the back of the dryer, but this is very uncommon, and only happens if they are very worn or broken. This can easily be diagnosed by a technician and if the motor is fine, will cost little to repair.Hope this helps.

Thanks

I want to know what an User EQ is?

Most Audio devices will allow you to adjust how the music is played. an EQ is just something that can increase or decrease audio Frequencies. there are usually preset EQ levels that will make Jazz, Classical, Pop music sound better. this is done by increasing the High notes or increasing the low notes to give you more of a bass sound. User EQ settings allow you to manage the frequencies more to your liking. If you want to here the high notes better or adjust the middle to hear the vocals better then you can increase those levels. Or if you love your bass sounds then you would increase the lower frequencies to give your music more boom.

Stereo Sound

You could start by adjusting the Treble and Bass. The treble is what makes the high notes more nodicable, so if you turn the Treble up you should be able to hear more vocals. The Bass is what makes the low notes more nodicable, so if you turn the bass down you should be able to stop the shaking which I'm guessing is the low notes. On the other hand if you have an aftermarket radio then there might be a Mute or ATT button. Theses are for instant quiet, just repress the Mute or ATT button and it should be fine. I hope I could help.

K750i low volume in the playback ,please give me a solution

Well... The speaker is ok and if you're using the headset it should be loud enough for you. If you want it to be louder just use earphones/headphones that are sound isolating to block out ambiant noise. The hpm-70 can kinda do that because they go in in your as opposed to sitting on the outside of your ear. The earpiece volume is really loud. I found it hard to hear to people in some places.

Good Luck
