It should be OK BUT if the JBL and the Logitech are plugged into different mains outlets you could get a hum from one or both sets of speakers. This hum is caused by an earth loop when the speakers are connect to different mains outlets.
The fix.
Connect a power board to a mains outlet and then plug the mains connections from both set of speakers and computer to this power board.

SOURCE: JBL Media 100 Speaker power?

Buy a power adapter from radio shack or similar place. You need a 1000mA 12 volt dapter. Just make sure it is rated @ or above 1000mA to avoid the adapter heating up and possibly burning. The whole setup is rated @ 850mA wich 1A(1000mA) should handle with enough head room. But it might run you about $15-20. I would just buy a cheap radio with rca inputs/aux input and use that. I got one from Walmart for around $40 and it plays CD's & AM/FM.

SOURCE: What is the dc input for JBL Media 100

They run @ 12 volts 850mA. So an adapter with center pin positive at around 1A(1000mA) would give it enough "headroom". This means it would run cooler and last you longer. Amperage consumption is determined by the power it is producing, how loud you are playing the setup.

SOURCE: Just wondering what the power supply output JBL Media 3 Speakers

I have JBL Media 3 Speakers running on the factory supplied power supply and the label states: JBL POWER SUPPLY, Model No. DV-9319B, Input: 120VAC 60Hz 35W, Output: 13.8VDC 1.7A, UL Listed3T58, E148325, CSA LR99152, Power Connection Diagram shows, Ring: Negative, Tip: Positive, CAUTION: INDOOR USE ONLY
PERSONAL NOTE: The power supply DOES NOT have the AC plug on the back. It is big hefty black block with an attached AC cord on one side and an attached DC cord on the other. My speakers are mounted high on the wall and run at approx.90% of full volume with Bass & Treble set flat. Actual volume and EQ settings are controlled via the sound card software based "Mixer Panel".

Just touch your fingertip to the input connector on the sub -- similar noise? That would be its amp picking up the hum of the room through your antenna-like body. IF that is the same noise, you need to make sure your input cable is shielded and connected at both ends BEFORE applying power to the electronics at either end.

Be mindful of electronic noise sources such as track lighting, UV lights, motors, TV's, etc, and route the signal and power cables well away from them.

Try reversing the orientation of the AC plug at the sub and see if that helps out.

The power button on your speakers is broken- possibly from friction due to heavy usage. Unfortunately, there is no way to really fix this that is worth your time- if you still have it under warranty, take it to where you bought it, or give Logitech a call to get them replaced. If you don't, it may be time to search for a new set. While it's more expensive, I would recommend the Logitech Z-313 or Z323 if you want a decent replacement. They will sound better than the R20s, too.

I get a loud intermitant buzz from one of my JBL eon 15-G2 speaker, no music signal just buzz. What is the problem do you think...? EQ circuit problem, speaker cones seem to be intact.


If you turn the unit on with no input and get a loud buzz, and when you put signal to it and you cannot hear the music but the buzz (Probably more like a hum). Then most likely the amp is blown.

How do you attatch the speaker unit to computer


The speakers hook up in the earphone jack, it often is a green plug. Get speakers with a subwoofer and you get really great, full sound. A subswoofer does not mean LOUD, but rather full, unless you are a teenager.

JBL Creature Speakers have very low volume


I had the same problem. Then I read about the volume controls on the right speaker. They are silver buttons for me on the front bottom left and right of the speaker. Now they play really loud!

Trying to hook up jbl sr4732 speakers the highs are to loud compaird to the bass or lows. im only using a onkio with a 100 watt per speaker.


These JBL speakers are not made for a home stereo reciever. It could be part of the problem.

I do know that they have a high frequency input and a full range input on each speaker.

I am going to guess that maybe you have them connected to the high frequency input.

Are you using 1/4 inch jacks connecting to the input of the speakers?

I don't remember these speakers having a input for wires.

You may have another issue using these speakers with that reciever.

The JBL speakers are 4 ohms each, it is very likely that the onkyo requires 8 ohm speakers.

Look on the back of the Onkyo where the speaker jacks are at and see if it says anything about the minimum impeadance.

The impeadance is the ohms. Most home recievers are not designed for anything less than 8 ohms. Some are, but most are not.

Using 4 ohm speakers on a system that requires 8 ohm speakers can cause damage to the reciever. Mostly at higher volume levels, it will cause the reciever to overheat and shut off, maybe short out a channel. It pulls 2 times the amount of current thru the output transistors as 8 ohm speakers.

Let me know if this helps you or if you need more help.

Give them a try. hope this helps:)
