I've just joined up and have a few questions about my newly acquired TimeWindow 3's. I've owned a set of second series Time Window 1's with the round DCM woofers (not 1a's) for several years, and love them, so I jumped on the TimeWindow 3's that appeared on my local CL. Unfortunately, the deal wasn't quite as good as I thought. I paid $225, knowing one looked nearly perfect and the other had some definite cloth wear like a cat went to town on it, and the knob was off one of the trim pots in the back, but the seller had the knob.
But things got worse after getting them home I discovered two tweeters were dead, one in each speaker that I've verified as open with a multimeter, and that the pot with the missing knob, was actually broken. You can pull the shaft out completely from the pot. Luckily, I sourced two replacement Vifa D19TD-07 tweeters today from a fellow AudioKarma member, I'll just need to cut the mounting flanges to the TW3 shape. The pot, now is a concern. I took some close ups of the shaft and it doesn't seem to have snapped off, maybe I can reinstall it after I get the rest of the pot out, and taken apart, but if not, do I have any options for replacement? The original seems to have written on the back Obata Electric Co and says 50 ohm, and also Ph-301. It's the third one down for the tweeter level.
I also have a question on grill cloth. I'm going to just do both speakers even though one looks fine, so that they'll match. I think I saw a post here earlier recommending the standard cloth from PE, but I also notice they sell Mellotone Premium, that is supposed to be a really dark black, instead of dark grayish black like many others. It costs quite a bit more, I think $19.90 a yard, and it looks like I'd need three yards to cover these. Does this seem better than the standard cloth and a better match for the deep black the speakers are now? Also, does anyone have any good instructions on just exactly how to make the new cloth covers? I realize you just need to sew one stitch in the back, but any pointers and tips would be appreciated. I have access to a sewing maching and someone that knows how to sew well enough.
I believe too I read that underneath the cloth is basically headliner material, I'll go back and try to find that unless someone has the info handy. I admit, I almost considered parting these out after finding out the problems, but I'm sure I'll find it all worth while after I finally get them fixed. At least I hope so. If they are even slightly better than my TimeWindows, they'll be worth it.
