Ironsave Posted July 28, 2011 Author Share Posted July 28, 2011 Well Cliff; I just hooked them up in the living room. Could not wait...... Th HK430 is awesome. I can't go past 35% without it getting too loud for the neighbors. (They are home). The speakers sound excellent. If anything; the highs are not as defined as the Heresy Is; but the thumping compensates. These will do VERY nicely in the bedroom (eventually in a 2 channel room). And no sub needed....... It is great to hear the fruits of my labor........ Thanks to all for your help! [] Quote Link to comment Share on other sites More sharing options...
bwilbur Posted August 1, 2011 Share Posted August 1, 2011 I did a set of KG 5.2 12" woofers before. They were polypropelyne, not paper; so that is my biggest concern, is cutting/ tearing the paper while removing the center cap. Ironsave, I am curious about your refoam with the polypro. Did you use foam or butyl surrounds for those? Also, did you use a polypro dust cap? I'd be interested in any details or pics.

Ironsave Posted August 2, 2011 Author Share Posted August 2, 2011 Brian, I used butyl surrounds. I did not use a dustcap; as the voice coil gap was larger. (I got it right/ no rubbing; without shimming). If you decide to replace the dust cap and shim properly; I suggest being careful with an exacto knife and you should be able to get it off ok..... It was more of a pain as the glue took longer to set and the rubber did not seem to want to adhere as readily as the foam and paper. Sorry; no pics available on those.......

bwilbur Posted August 2, 2011 Share Posted August 2, 2011 Thanks, that is good info and encouraging. I might have to put new surrounds on a KLF-C7. Where did you purchase the butyl surrounds? Did you notice any changes in tone after replacement? Quote Link to comment Share on other sites More sharing options...
Ironsave Posted August 2, 2011 Author Share Posted August 2, 2011 I got my surrounds from Parts Express. (I did a bunch of measuring and rechecking to make sure that it would fit). Depending on what exact size you need; I would look there and also Simply Speakers and perhaps Ebay. (Ebay is where I got the L 36 woofer surrounds). I noticed no tonal difference. The buyer was pleased; and said he would not have known if I did not tell him... Quote Link to comment Share on other sites More sharing options...
Rivernuggets Posted August 4, 2011 Share Posted August 4, 2011 Nice work Matt. A little DIY increases sound quality. [] I've used a AA battery to center the voice coil. Hook it up to the woofer in reverse polarity. The woofer will suck in and stay, with the voice coil suspended, not touching anything. A good method for keeping the original dust caps intact. This means it's a two step gluing process. First glue the surround to the woofer cone, let dry/cure. Then do the battery trick and glue surround to the basket. The shims are more of a guarantee in centering. The battery comes in when replacement dust caps can't be found, or aren't desired. Quote Link to comment Share on other sites More sharing options...

That is a great procedure to do "next time"....... (I was really worried about the L 125A woofers ripping when I removed the dust caps).... This will be useful in the future; I am sure.....
