Sub-bass rattling in right-ear

There's a terrible rattling in the right-ear of these headphones whenever a bass tone between 40-80 Hz is played. This doesn't occur in the left ear. Anything that can be suggested to fix this would be welcome!

My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?


If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

Reduce the amount of boost or, better yet, turn off the bass boost. With your installation, overemphasis on the bass is causing the rattles and distortion

Hello there! I have an 8-10 yr old Bose Accoustimass 10 speaker system connected to an Onkyo TX-DS595 receiver. After moving and setting up my system the Bass Module has almost no base coming out although...


What is your crossover setting set at?
If it is set at 40 HZ, this would explain weak bass; as that Bose system sends ~120HZ down to the sub.

I reccomend checking the crossover setting to 120 or 100; with all speakers to small.

You may need to increase the db setting on your sub as well......

Good Luck.

I have bought a pair of Shure SE210 headphones for my iphone but the sound is lacking all the low frequencies for most of the music or videos i try to play. The headphones work perfectly on any other...


No, there are no known issues. Typically a lack of bass response is due to a poor seal with the ear canal. The headphones use sealed ear canal is a resonant bass chamber. Thus, if there is not a good seal, the bass will be significantly lower.

One of my technics' 1200 turntable's tone gets too high


You can try adjusting the pitch's gain, which is located on the pitch control circuit board. Only problem is that you'll have to take apart your turntable in order to get to that section (its on the bottom).

If that does not work, your pitch might be bad, or one of the main circuit drive IC's might be bad.

Hope this helps some.

There is no "perfect" setting that can be placed in a manual. It's all done by ear. Your settings will vary depending on the vehicle you are in, the type of enclosure you have, the type of music you listen too, how much voltage your deck put's out. There are many variables, but I can try to give you a basic guide.

First of all you need to know your enclosure. If you have a ported enclosure tuned in the mid to low 30's you may want to set the low pass to around 70-80 hz with your sub sonic set at 30 hz. this will give you the higher bass frequency you need for the loud bass you want, and protect the sub from going too far below the tuned frequency of the enclosure, and losing it's composure.

As far as the gain, and bass boost are concerned, you just have to adjust them by ear. First adjust the radio volume to normal listening levels, by that I mean as loud as it can go without the speakers in the car sounding like ****. Now you adjust the gain first. slow turn the gain control, carefuly watching and listening to the sub.. Adjust the gain to the point of the woofer getting a lil sloppy then back it down a bit until the sound is clean again. Now do the same with the bass boost. if there is a bass boost frequency adjustment, set that as close to the tuned frequency of the box as you can.

If you are in a sealed box the adjustments are a bit easier, and are all about taste. Adjust the radio as described before, and put on your favorite song. Next start udjust thing lowpass frequency to taste, not too high tho, try not us higher than 100 hz in your sub's for better sound. Sub sonic is not quite as important in a sealed box, as there is much less danger of the sub losing control.

Well good luck, and hope this helps!

I have a problem with earbuds or headphones, when I plug the earbuds in it only plays on my right side of earbuds.


Hey...that's the exaxt same thing that happened to me. On the same side too.

If you've had it for awhile the only thing I can suggest is replace it.

"cracking" noise


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.

How should I wire up this amp and sub


The amp's not actually a very good match for the sub, since the sub can be wired for 2 ohms or 8 ohms, and the amplifier is most efficient at 4 ohms in bridged mode. My advice would be to wire the amp in bridged mode, and wire the sub for an 8 ohm load. To do this, the amp's (+) wire should go to the (+) terminal on one of the sub's voice coils. Then run a wire from the (-) terminal on the OTHER voice coil to the (-) terminal on the amp. The remaining (+) and (-) terminals (on opposite voice coils) should be connected to each other with a wire. Your original wiring setup had the amplifier connected to only one voice coil, while the other voice coil was shorted.
