As an audio professional and long time ham, I would do three things. 1) Look carefully through the audio chain and the AGC to make sure there isn't some problem that is causing low audio gain. My two K2's have plenty of gain, but the one that I bought six months ago came with a couple of solder bridges that screwed up the audio. One problem was on the control board, the other on the DSP board. 2) The setup menu for the KDSP2 includes settings for audio gain with and without the DSP engaged. I generally set both for a few dB of gain. 3) The K2 loudspeaker is a pretty efficient one, and I doubt that you will easily find one that is more efficient. I've picked up some little "cube" loudspeakers at hamfests that improve other radios, but it does not improve the K2. In general, small loudspeakers have poor efficiency. If you want more level, look for a much larger loudspeaker, and try to choose a 4 ohm loudspeaker designed for sound reinforcement use. Hi-fi loudspeakers are generally poor choices -- they compromise efficiency for sound quality. FWIW, I generally prefer to do my serious operating with headphones, and every set of cans I've ever tried give me plenty of level with the K2.
