Ron, I too am hard of hearing and have tried many speakers, the best being Sounds Sweet. All of those required 3/4 to full AF. My K2 is on the second shelf and I never use the internal speaker from any radio. Tom Hammond, N0SS, built for me the project speaker mounted in the Elecraft cabinet. He added an amplifier. It WORKS wonderful. 1/4 turn of the AF and it's perfect. I couldn't be happier.

This was a problem on a number of units. Reply: ---------------- BENT SPEAKER Some speakers arrived at the builder bent so the voice coil rubbed, but that was pretty obvious and not just a low-volume issue. Even CW tones were obviously distorted. Mine was one of those, and I found it was very easy to bend the frame. Indeed I fixed it that way with a large screwdriver to gain leverage between the edge of the magnet and the frame! Apparently during travel somewhere between China, where it was made, and Oregon via Aptos and other places unknown, the speaker was subjected to enough shock to bend the frame. After messing with it I have no doubt that would be easy to bend the frame by dropping the speaker, in its padded box, from a perfectly typical height encountered in shipping that would produce no other indication that the box or the speaker had been abused. It takes very little force at all. The weight of the heavy magnet suddenly "stopping" does the bending. Like the problem with over-tightening the bolts, it's all a matter of a very light-weight and bendable metal frame on the speaker. MORE VOLUME If there's nothing on top of the K2, one can make a significant increase in the volume for a listener in front of the radio by simply providing a reflector. A stiff piece of paper shaped in a curve and angled over the speaker opening so the sound bounces off and forward will make a big difference. My impression of the post that started this thread was that the operator needed more than a doubling or tripling of the audio level though. I'm inclined to agree with those who suggested that there is something wrong in the audio channel of his K2.
