You just may not be used to the full sound this unit creates. Most amplifiers/speakers cannot replicate the frequencies this unit provides. Simply stated, you just may not be used to hearing lower frequencies. However, here are a couple of things that you can try.... 1. Check you music source. If using an MP3 or a music program, make sure that your equilizer settings are flat (or on another setting with less bass.) 2. Subwoofer placement is critical. You may have this unit placed in the corner of a room or under a desk. These placements can actually increase a subwoofer's response and make the sound more "boomy." You may want to try moving the sub to a different location (ie: to the middle of the wall and away from furniture.) This may help reduce the overpowering bass you claim to experience. 3. This subwoofer has a ported speaker - meaning that there is a large whole on the left side of the subwoofer cabinet. This allows the bass created by the woofer to exit the casing easily to create a more bassy sound. The drawback to this design is you lose a bit of the solid "thump" you would get from a non-ported design. Try sticking something into this hole (towel, nerf football, etc) to block the sound coming out of the port. Just make sure whatever you use does not fall into the subwoofer! I hope one (or a combination) of these help. I personally have these speakers... for what you pay, you get pretty good quality/sound.

Need wiring diagram for bass w x 10


You have not mentioned what equipment you would like to connect to this active subwoofer.
Assuming you have an AV Receiver, you will require a single long RCA to RCA subwoofer cable. Connect the left input (white socket ) of the subwoofer to the AV Receiver subwoofer pre output.
Leave the front crossover knob at 100Hz , Phase at 0. While playing an audio track slowly increase the subwoofer front volume to suit your taste. If you are using big floor standing speakers along with the subwoofer reduce the crossover frequency to 70Hz. Phase should be adjusted to blend the front speakers with the sub.bobhifi_6.jpg

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've connected a powered sub (bazooka BTA10250D) to my factory system (09 altima coupe 2.5s). I want to be able to control bass on the component speakers and the subwoofer separately. There is no sub out...


We used to use what we call bass blocker capacitors on the component speakers to block the bass coming from the head unit and to allow the bass to only come from the subs...there is several values of these capacitors that you can use(different values correlate to different frequencies). These type of capacitors are available at Radio Shack. You will need to request a NON-POLARIZED Electrolytic capacitor at a voltage rating of not less than 25 Volts...As for the value of the microfarad rating..you may need to experiment with different microfarad values to get the sound you desire...standard microfarad values are 1uF, 2.2uF, 3.3uF, 4.7uF, 10uF, 22 uF, 33uF, 47uF.
You probably won't need to go any higher on the value than those listed....in my experience, I have found the 4.7uF and 10uF to be good for most speakers...to install these...you need to put one inline with the positive lead to each component speaker.

I have a KLH ASW10-125C Subwoofer and a Harman Kardon AVR 3600 receiver. What should the setting be for volume, phase and crossover frequency?


Home Theater

volume - personal taste - usually just high enough that you notice the bass - try turning down until you don't notice it then turn up one notch in the switch

phase - depends on distance from other speakers - try initially setting to 0 degrees

cross-over frequency - depends on your other speakers - try setting at 60-100Hz

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.

Logitech Z-2300 subwoofer/Bass volume cannot completely shutoff


Make sure the wired remote is connected completely and if that doesn't work try putting a pillow or a pile of blankets to cover both the subwoofer driver and the air port on it and that should reduce the sound coming from it. Also if it is in a corner or on a solid floor like wood or tile i would move it to a less enclosed space with carpet or a rug. Thats all I got I hope that helps.

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!

Subwoofer moving wrong way possibly causing damage!


Hey i'm no expert either but maybe just maybe your amp has a subsonic filter on it which cuts out the lowlow bass maybe check that and either disengage it or turn it all the way down if it even has one thats all i can think of unless you have a ported box and going below the boxes tuning frequency other than that im as stumped as you are-good luck with it

Very quiet subwoofer


I had the same problem until I decided to plug the speaker system into my desktop instead of my laptop. Now, all is well and I had to turn the bass control almost all the way down... I was shaking the house! Must be something to do with the quality of the laptop output.
