DMC Time Windows 3 Intermittent Crackling
These are now getting very old, and the bass drivers are at the top. Because of their age now the bass cone suspension could very well be starting to sag and cause the voice coil scratch in the gap (it’s called polling). They have 4 screws undo them and turn each bass driver 180 degrees and remount them, hopefully this will cure your problem. http://img.photobucket.com/albums/v223/mhardy6647/timewindow.jpg Cheers George |
Can’t remember back that far, but yes there was a trick to it, vaguley remember as a youngster, with your palm under the top cover and whacking it off, but don’t hold me to that. Maybe someone else here is old enough to remember. But the sagging of bass drivers is common with old drivers, Kef B139, B1814, B300 etc etc. Cheers George |
Well, that was quite the adventure. Accidentally broke a wire loose from the circuit board taking them apart (putting them back together really) and just had my first ever session of circuit board soldering. A success, fortunately. Now another question for anyone who might know: without the sock on, the speaker actually looks quite different from the one posted above and from all images I can find online. Please forgive my utter lack of appropriate terminology but mine don't have the same tweeter speakers (I assume that's what I see in the photos) right below the main drivers. Also, mine have 2 airholes (no idea what they're called) on the same side about a 1/3 of the way up as opposed to their being on both sides and lower down in the ones pictured online. Here's a picture of mine: http://s18.postimg.org/m3kh3wfo9/DMC_Time_Windows_3.jpg I don't have any specific question. Just a little perplexed. Anyone have any thoughts? |
Never mind. I found my answer here: http://www.avsforum.com/forum/89-speakers/652191-whatever-happened-dcm-s-steve-eberbach-3.html Great thread for all Time Windows questions if anyone stumbles across this in the future! |
