Sean, nice damping mod. I have used "Dyanmat" in the past (mostly automotive applications). I don't know why it never occured to me trying the stuff on mids / woofer baskets. Years ago I experimented with Altec Voice of the Theater speakers and remember adding foam insulation on the back of the horns to reduce ringing...and it helped. I think I'll try it.
"Parts upgrade" on crossovers -Any experiences?
I remeber upgrading the crossovers of a pair of B&W DM12's with esoteric resistors, caps and wiring (about 10 years ago). In the end I got a different speaker. The bottom end seemed improved and the highs were more delicate and smoother, but the midrange had lost some of the magic. I could not deal with the decreased midrange quality so I re-soldered most of the parts back to the crossovers but left the upgraded wire (the wire in there looked like tined copper and was tied with a Molex connector to the board!). I changed the parts since I felt that early 80's speakers could only benefit from higher quality parts and was worried that the cap values might be out of spec. I am currently using a pair of KEF 101 and I've been thinking about upgrading crossovers with Solen Caps, maybe some Caddok Resistors and Cardas or Kimber wire. The KEFs sound great but if I can get more out of them, I might give it a try. Anyone do similar upgrades with an increase in ALL aspects of your speakers performance...or have BAD results...or find the end result a mixed bag of better here, but worse there (like me)? Also, any input on what parts / brands to use and which not to use? Are Solen caps good choices (or are there others that work much better for this application)? Resisters Brands?
I am purposely leavig out the issue of active crossovers (don't want to find 4 identical monoblocks to run my speakers).
