Inserting a razor blade and working it around the edge worked very well at cutting through the remaining glue. I could hear a click where the plastic was de-bonded. Around the inner circumference of the pole piece using a incredibly tenacious shellac that looks suspiciously like Indian Head™Ī light tapping with a finger around the outer lip revealed my air chamber glue had finally let go in a few places. Around the outter lip using a hard glue that's brittle (even on my 1990 speakers) and subsequently leaks The air chamber is glued in two areas using two different adhesives.

However, it is not necessary to take apart the entire compression driver to repair a leaky air chamber. I took one driver completely apart to show how the K55-M is assembled. Here's some pics and notes for anyone else that would like to attempt the repair.

Since then, for about the last 4 weeks, my midrange performance has been noticeably harsh.Ī call to Bob for driver / horn gaskets and time to pull the drivers from the La Scala. A touch of the hand to the black cap piece, and the buzzing would change pitch or stop all together. When I got up closer to the speakers, I could hear a buzzing sound coming from the rear of the squawkers. I was playing some synth music on my system that was distilled from pink noise. My questions are this, do you think it is the squaker, or the AL-3 network that is to blame? Also, is there a test I can perform to check? When I first set this system up, the AL-3 speakers sounded a good bit cleared than the other 4 with the AA's with the fresh sonicaps.

I next put on a Beatles LP, and went around in all channel stereo, and found the mid-high tones are much better on the other 4 LaScalas which have newly re-capped AA networks, two of them with new tweets as well.

That actually made me realize the matching AL-3 LaScala was also making the distorted noise, just to a lesser degree. I used some black silicone gasket maker around the fringe of that squaker cap, and it helped. That resonance was causing the cap on the back of the squaker to vibrate and make a hell of a noise. I was running the Spears & Munsil HD Benchmark on my Oppo BDP-93m and there is a scene in TrueHD that has a note piano note that reoccurs often, and that note was causing a great deal of noise manifested as resonance. I have recently discovered a problem with one of the LaScalas in my 6.2 setup.
