Question about Philips MMS171 Computer Speakers

1 Answer

Sub issues I was playing my music off my cpu at a regular volume on these speakers that I've had since christmas and have had no problems up to this point. I had my music going and then all of the sudden the music stopped and all you can hear is a deep humming bass. The volume control does nothing, all the cables are in the right place so im not really sure why its making the noise.

Re: Sub issues

Would suggest that the power amp in side the speakers havs failed. Try to plug the speakers into a ipod then you can prove if tis the speakers or the Pc.

Over time the TV volume and the SurroundBar volume get out of sync and we keep having to manually adjust the SurroundBar volume to match them up. We are currently using the DirectTV remote to control

Unfortunately, the system does not work well around other wireless devices. When watching Blu-rays and listening to music, the system works fine, but when I play my Wii or Xbox 360 the subwoofer loses its connection to the bar and stops working. Sometimes I can play for up to an hour without the sub going out of sync, but it always ends up happening. Many times and several times in a row it would immediately go after sync right after I fixed the problem. Polk lists the wireless sub as a feature but it's actually the worst part of the package for anyone with other wireless devices in the same room.

Check the online link to the PDF for more information about sync instructions.

Hey I've had my Logitech z506 speakers for a few

I don't know for certain but, this is usually a sign of the overload circuit in operation. Speakers are not designed to be used on full volume constantly. Next time this happens try and turn them off for a couple of minutes, when you turn them on again try with the volume lower than when you turned them off. If you are regularly using them at full volume, then maybe it is time to invest in a more powerful set. Buy them by their RMS power output, NOT by their PMPO (peak mean power output) this is already an inflated figure and is usually about 4 times the real power output. I hope this helps.

Logitech Z-5300 subwoofer from computer to i-pod problem...

The best thing to do is to contact the manufacturers. From this i understood that your speaker system is new. You surely have the manufacturer's guarantee. So its better to contact them than to get it repaired or replaced for free. Sir please do not try to open the sub as it will void the guarantee policy.

Hope your subs come into play as soon as possible.......
All the best...

My speakers simply will not turn on any more. i was playing music on them and then all of the sudden the power just will not turn on in the sub. Does this mean i blew them out? I didn't really have the...

Maybe. There should be a fuse. It will prolly look like a black knob on the back of the sub. Unscrew it and check the fuse. Replace it with a good fuse.
If it keeps blowing the fuse, the problem is likely in the speaker. If the problem is inside the sub, you may need to repair/ replace the circuit board inside the unit. If you can't get one you will have to replace the speaker as it will keep blowing fuses.

Hello Ronaldlora
Happy Holidays

Hi, this is a particular problem for this speakers, and subwofer, it is a resistor inside the sub, you have to fix it in a repair shop, or ...sadly, change for another model of Creative Speakers, for example one good one is the 7800 Spk. good ones.
but like I say is a problem that creative labs is aware too.
