| 437401 | 2006-03-11 07:27:00 | Well, another problem with my Philips MMS460 5.1 Speakers again. There are frequent "crackles" which you can hear from the subwoofer. I've got this set of speakers from Hong Kong, and I'm currently living in Canada. I already bought power converter, but will it be the power that's affecting it? Could someone please tell me the solution if you have one? Thanks in Advance.:cool: |

| 437403 | 2006-03-11 16:27:00 | Sounds to me like a cracked diaphragm or cone...did it ever get overdriven? (turned "WAY UP?) If it's a cone/type speaker, it might be the voice coil being driven too hard and hitting the back of the magnet or the inner frame......if it's a flat resonator type, then it's time for a new one. |

What's a flat Resonator? and I've never turned it all the way up. |

| 437405 | 2006-03-11 17:54:00 | The style of flat resonator-types are usually in high $$ units . . . they were made originally by Barkus-Berry and they were just sound wave movers with a lot of power . . . the flat panel took place of a cone and whizzer to propel the sound waves into large arenas and theaters etc . I have a set of them from a torn-down theater that probably cost the theater over $20,000 . 00US when new . So far I have not found an amplifier powerful enough to drive them well . There are newer and smaller versions of them that are used in quality sound systems yet, as the patent expired on the device years ago . . and it is now an open for use technology that a lot of companies use now . The panels are usually not visable . . but they are, for simple terms, just the floating panel that drives the low freqs to you . However, I digressed . . . I still think there is either an over-drive condition going on here, or the remotest possibility that some foreign object has found it's way into the audioplenum . . . did you say you just moved to Canada? . . . . . . . . . might shake the woofer and listen for something "loose" there that doesn't belong . |

If they are random crackles not related to any particular music level, then they are most likely due to a poor connection (wriggle and thump test) or power line noise impulses . If the latter, the only way to test is to install a power line filter (not just a "spike suppressor" but a proper mains filtering unit) or borrow a UPS and run them off that for a while with the UPS power plug pulled so that it operates on battery . You should get up to an hour or more out of the UPS on that light load . That will eliminate the speakers if they are independently powered units with inbuilt amps, but it won't eliminate power noise entering through your sound card . The latter would be relatively rare though, because the PSU in your computer will do a fairly good job of filtering the input volts . Cheers Billy 8-{) |

| 437409 | 2006-03-12 00:42:00 | Update: My subwoofer now even has a "thump" sound. it goes, "thump!" now, does it have to do with sound drivers or sound cards? Do I need a new sound card? Because i'm using a on-board sound right now. Any ideas? | hpratvfrk (9558) | ||
| 437410 | 2006-03-12 01:32:00 | I thought that was what sub-woofers did. Most owners complain when they (the speakers) don't go THUMP :thumbs: | Graham L (2) | ||
