It's either a bad speaker or could be the mini plug. Maybe time for new speakers.

Why are my headphones making a vibrating sound on the left side, when there is a lot of bass.


Each speaker works independently from each other. One speaker may use more low frequency tones than the other one.. Low frequency tones create a lot more noticeable vibration than higher frequency tones. You can reduce it by turning the volume down a little on the left speaker. It is possible that nuts came loose on the speaker.

Noise Control and Being a Good Neighbour


Whether you live in a private dwelling, or in a multiple home dwelling, such as a condo or apartment building, one should pay attention to controlling the sound from home theatre and stereo systems. In this case, we are generally talking about managing the bass frequencies of the sound system. High frequencies tend to be absorbed by common building materials. The physical/mechanical aspects of sound transmission are complex, but the average person can apply some simple and inexpensive methods to minimize the unwanted transmission of bass frequencies beyond the listening space. <br /> Transmission of bass frequencies can often be controlled by placing bass-producing speakers on pieces of rubber material. These can be as simple as scrap pieces of rubber mat, salvaged rubber feet from other equipment, etc. The physical placement of speakers can determine the amount of bass frequencies that the sound system produces in the listening space. Generally, more bass is generated by placing speakers in corners, and along the shortest wall of a room. <br /> Of course, adjusting the bass and volume controls is a method that can be used to satisfy personal tastes or to control the sound in any situation. Many home sound systems now employ a subwoofer to provide enhanced bass response. This can add lifelike sound quality to the home listening experience, but it is probably the source of most noise complaints. The subwoofer channel of most video program sound tracks has more bass intensity than one generally finds in television, radio or music sound sources. To prevent disturbing the neighbours, one should employ all of the methods detailed above, to reach a happy medium of being able to enjoy full spectrum audio within reason. Personally, I ask my neighbours listen in their homes, while I adjust my maximum sound system volume to a level that they would not complain about. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />

I put a sub in my 2002 Altima but when I turn it up the bass cracks on the door speakers??? What do I do to get all the bass on the sub


Hi Ethan,

What you're looking for is called a "crossover". A crossover is an electronic filter for an audio or speaker circuit. In an audio circuit, a crossover is used to prevent or pass certain frequencies or a range of frequencies from passing through it. Since your sub will reproduce the bass or low frequencies, you don't want other speakers to reproduce them. A band pass filter on your door speakers will do this for you. A band pass filter passes only a range or "band" of frequencies and blocks those that are above and below the range or band of frequencies selected. Installing a band pass filter will prevent the very high & very low frequencies from getting to the door /dash speakers. Likewise, you should consider connecting a low pass filter to your subs, too. The low pass filters work a little differently from of the way band pass filters work - they only allow low frequencies to get to the sub - blocking all the other higher frequencies (your other speakers are better suited to reproduce those). Lastly, you would install a high pass filters on tweeters. Tweeters are designed to reproduce only the high frequencies - sending mid and low frequencies to them is wasting power and can cause damage to them.

You purchase the filters for specific crossover points (the block / unblocked point) as determined by the individual speakers. If a sub has a frequency response of 20Hz - 100Hz, a low pass filter of 100Hz would be ideal. Remaining filters would need to begin at 100Hz - assuming the mid-range speakers have a frequency response beginning at 100Hz. A band pass filter of 100Hz - 3KHz would fit the bill nicely if the mid-range speakers go up to 3Khz Match the high end of the band pass to the high end of the frequency response of the mid-range speakers. Next, a high pass filter at 3KHz would allow only the high frequencies to your tweeters. Basically, you want to have the entire audible range 20Hz - 20KHz covered by the speakers and have the crossover points that match the frequency response ranges of the speakers.

I hope this helps & good luck!

Is the bass boost the gain or frequency knob?


Bass boost simply adds DB or gain to the bass signal. Some like it, some dont.
The frequency knob is the Low Pass Filter (LPF) that cuts off the amp output above
the set frequency. A bass system usually cuts off below 400 HZ and more often 200HZ.
A good, rattle your car bass note is in the 25-80HZ range or lower but most amps and audio
input devices cant attain a good low note with clarity.
"Low-pass filter allows only frequencies below the crossover point to be amplified. A high-pass filter allows only frequencies above the crossover point to be amplified - useful for keeping low bass away from small speakers, so they can play more efficiently."

Do i have to remove the pin between the two speaker treminals on my old mission 780 speakers before i bi wire them


Yes, the two sets of terminals are for the tweeter and bass driver.

When you bi-wire you want the low frequencies to go only to the bass driver and the high frequencies to go to the tweeter..

Please see this link for more information:

What do the phase and cut off controls do,manual does not explain much.


Phase reverses the polarity of the driver so it can be matched to the other speakers and bass-reinforcement characteristics of its position in the room. You don't want the sub 'sucking in' while other speakers are 'pushing out' or a bass cancellation will occur.

Set it, listen to bass from your normal seating position, reverse it and observe if the bass gets subjectively better. Leave it in the 'better' position.

Cutoff is a variable for the highest frequency where the speaker 'cuts off'. You can experiment with adjusting it for what sounds to you like the smoothest transition betwen the sub and the othere speakers. You don't want a lot of audible overlap where the sub and other speakers are acting on the same frequencies. It may sound to bassy in that area.

Whats the difference between a speaker and a subwoofer


a sbwoofer is ment for producing bass by playing low frequency notes at an amplified power. subs move air vibrating off of your trunk and creating bass. a speakeris ment to produse high and midbass frequencies. thus having a tewwter and a small woffer cone. trying to get bss out of a door speaker usually results in very bad distortion which will actually blow a speaker very easy

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.


I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
The High-Pass control
determines the frequency at
which the main speakers
will start reproducing
sounds. If your main speakers
can comfortably reproduce
some low-frequency
sounds, also set this control
to a lower frequency
setting, between 50Hz –
100Hz. This will concentrate
the subwoofer’s
efforts to the ultradeep
bass sounds, while your
main speakers continue to
reproduce the mid-bass
information. If you are
using smaller bookshelf
speakers that do not extend
to the lower bass frequencies,
set the high-pass crossover
control to a higher setting,
between 125Hz – 180Hz.
With this setting, your main
speakers will not have the
burden of reproducing any
low-frequency sounds.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
Final adjustment and blending
of the low-pass and high-pass
controls may evolve over several
listening sessions. A good
starting point would be to set
both the low- and high-pass
controls to the same frequency
and adjust from that point.

My 6x9s have stopped producing bass together


There is a short in your wiring somewhere, unfortunately, it would be impossible for me to tell you where it's at. The best advice I could give you is to start at the speakers and work your way back. Hope this helps and good luck!

Noise/No Bass in Delco Systems stereo


You have a possible fault in your wiring of the speakers, the Phases of the speakers are crossed over resulting in cancelling of the low frequency- bass frequency. Hence please reconnect the speakers front and rear with the positive/ negative to the corresponding positive and negative of the speakers.If you are unable to fix the marking of the polarity use 1.5 Volt cell to connect to the speakers , if the speaker moves up the terminal on the positve of battery is positive. reconnect and test with a good bass song for result. Helpful. Good day
