Subwoofer volume and sound

My subwoofer isn't producing much sound even after turning up the volume on the back and through the receiver. It doesn't have very much bass to it either.

I had the same problem when i tried to adjust speaker output levels, distance and equalizer manually without using audessy setup..so i reset everything to factory setting (0s)..and then ran 
audessy setup..reduce volume on your subwoofer to slightly above minimum(behind the subwoofer) before running the setup..once audessy setup is completed successfully..i started changing setup
manually..changed speaker config for front speaker to small (it is set as large by audessy setup), this should automatically adjust center and other speaker configuration (if not make sure to set them to small as well), then set the cross over frequency to 120..increase the volume on your subwoofer and now you should hear it fire..if this does not help..try playing some rock music with all channel streo mode..if your subwoofer does not fire even for this..then take the system back for exchange..

This solution works. When I first hooked up my speakers and ran the audessy setup, the sub was turned all the way up in the back. I then had hardly any bass. I then turned down the sub on the back and ran the audessy speaker setup again and then turned up the sub in the back. now it works great. thanks.

I have the following setup: AV Receiver: Pioneer


Very common problem with today's receivers. Receivers made today don't have a true preamp section in the amplifier and do not amplify the sound to the extent of an older receiver. I have large 15" front speakers on my system, and have stuck with my 15 year old receiver just because I know that a new receiver will not have the power to drive them well. Many of the newer receivers need to be turned up to 50-60% before you can even hear anything from the speakers.

The symptom sounds like an open signal shield somewhere and the cable is acting like an antenna for airborne electrical noise.

Disconnect the RCA cable at the sub. Is it still humming? NO? Problem is external to it. YES? Internal. Broken ground somewhere.

Recheck all connections making sure to twist the RCA head as you install it so oxides will be worn off.

Consider what may have changed in the environment regarding electrical devices, motors, magnetic sources. Ensure signal and speaker wires as ar not running are as non-parallel to any power cords as practicable.

Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

You can prove the sub pre-output works by running an RCA cable from it to the input of a tape deck, TV or any other device that accepts Line In and will either display it or play it. Test it on VERY LOW volume at the receiving device.

There is no sound coming out of the subwoofer


I assume it's an active subwoofer, since it hums. Did you activate sub in the receiver menu? Did you turn up the volume on the sub?

Pioneer VSX-815-K receiver with sub in standby


Have you looked in the manual?

No sound from subwoofer. • Make sure the subwoofer is switched on.
• If the subwoofer has a volume knob, make sure it’s turned up.
• The Dolby Digital or DTS source you are listening to may not have an LFE channel.
• Switch the subwoofer setting in Speaker Setting on page 40 to YES or PLUS.
• Switch the LFE Attenuator Setup on page 61 to LFEATT 0 or LFEATT 10.

My home theater speakers make a constant hum whenever my receiver is on. The loudness of the hum changes with the volume control, and goes away entirely when the system is muted. All components are plugged...


jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.
