Thinking out loud.. what would happen if something like hard dust particles came inside the vent and in between the coil and magnet? 🤔

Update, i removed the woofer and gave it a thorough check again. Everything seems solid and well glued together, i also connected the woofer outside the cabinet and played a test tone through it, at least i now know for sure that its the driver itself making noise. I also took a few pictures

Yes i will remove the woofer and give it a thorough inspection one more time, this time i will also try to play some test tones on it while its out of the cabinet. Thanks for the support and suggestions, i really hope i have overlooked something.

Thanks for the advice. Yes these speakers are rare and hard to come by, i also think they never got the recognition they deserved, i think part of it is because of the history of the AR brand, every time the brand name was sold they seemed to lose some of its reputation. But for this Hi Res series as well as the HO series while they were owned by Recoton were of good quality, a peek into their web site these days just make me wanna cry!

Thanks, yes i just checked again, nothing suspicious to see, i might have to remove the woofer to really be able to move the surround foam, but so far it seems tight glued to the cone and no cracks. Would it also be possible that the magnet can get out of alignment?

Sometimes i notice a ''thump crackling'' sound from one of the woofers of my powered tower speakers, there is no scratch sound from the woofer if i push it in or out by hand, the ''thump crackling'' sound seems to come at a spesific frequency. Strangely enough, the woofer measures ok. 4 Ohm, but i guess there still can be something wrong with it? I have been looking around the internet for spare parts, but no luck so far. These speakers have a built in 500W Sunfire plate amp to drive the 15'' woofer. Already spent a couple of $1000 for repairs on 3 of these plate amps, so i dont want to give up on these speakers, i also think i will have to spend a lot to get something else performing as good as these. Overall specs of the speaker: Frequency response: 18-23000 Hz +- 2 db The crossover frequency for the woofer is at 120Hz The internal volume of the speaker is about 92 liter or 3,25 cubic feet, the cabinet is sealed. I dont know the sensitivity of the woofer itself, but overall its 95db 2,83V 1/m I've looked at the parts express site, there i found this Dayton woofer RSS390HF-4 15" Reference HF Subwoofer 4 Ohm Here is the pdf with full specs of the Dayton woofer Can this woofer be used to replace the original woofers, or maybe someone have other suggestions? ~~Leif

That was great BluesMan57! Reminds me of early Magnum. I say early because the song and the album below here was recorded in 1980 but released1982. The album Chase the dragon is the 3rd studio album of Magnum

I've heard about some people use ultrasonic washers to clean their vinyl records.

The first album i bought was Judas Priest - Stained Class. I was between 6 and 7 years old, tormented my parents with this album for years, had to get up early every morning to play it in the living room before school.. At least they never had any trouble getting me out of bed in the morning..

Sounds like this one will be just as good as the last one

I suggest you try either ''dBpoweramp'' or ''Exact Audio Copy'' for ripping CD's to flac, also a copy of ''Mp3tag'' can come in handy to get the correct tag info on some ''problem cd's''
