Phil,
I did use the grill and gasket update and the gasket gave me adequate space from the replacement speaker front to the case to allow distortion free output. I had original applied small stick on feet near each corner which I think works quite well. I really think the maximum speaker output for such a little one occurs around 30+ volume setting with a strong S reading. That is too loud for my pleasure. I have added the Bose portable rechargeable stereo speaker to give higher output level. Personally, I think this speaker audio output is well designed, it is just an issue with some of the speakers not being symmetrical in the cone installation. Elecraft is excellent in the replacement process. I was able to slip the new speaker with grill and gasket into position without removing anything and found the existing screws worked better than the replacement bolts. YMMV. 73, Bill K9YEQ From: [email protected] [mailto:[email protected]] On Behalf Of phil_ad5x Sent: Wednesday, September 19, 2012 8:25 AM To: [email protected] Subject: [KX3] Speaker Buzz - (Probably) my last update As some know, I had a speaker buzz in the 400-800Hz range at low to moderate volume levels (15-20) that was so bad that it made using the internal speaker completely unusable for CW. The biggest improvement occured when Elecraft sent me a new speaker as the original speaker cone was offset and would touch the grill. However, I could still get the buzz at higher volume levels(>25). I significantly improved this by putting layers of black electrical tape between the bottom of the speaker bracket and the bottom case - i.e. I blocked the gap with layers of tape. But I've never been happy with the tape. My latest "fix": I took a 0.375"ID 0.625"OD rubber gromett (Mouser part number 534-745), snipped it, unfolded it, and installed it between the speaker bracket and bottom cover. This has comletely eliminated the buzz, except at maximum audio level (where the buzz is only just apparent). I've uploaded a couple of photos in the AD5X photo album that illustrates this better than words. Works great, and I'm a happy camper now! The only issue would be the hassle of keeping track of the snipped gromett if I were replacing internal batteries frequently, but I use external power. Incidentally, for serious operating I do use headphones. But I use the internal speaker for casual operating and general listening while working on projects in the shack.
