Several months ago, I bought a small extension loudspeaker at a hamfest to use with my radios. I liked it so much that I bought a half dozen more. It's a little black rectangular box 3"W x 2 1/2" H x 2 1/8" D, and has a nice mounting bracket. It weighs about 8.5 oz.
The DC resistance of the voice coil is about 4.5 ohms, so it is probably an 8 ohm loudspeaker. When I plug it into the Ext Speaker jack of my K2, the resulting sound level is about the same as with the built-in speaker, and the sound quality is OK. The box comes apart neatly with four screws, and it's a nice looking little 2" diameter cone with a dome tweeter. The loudspeaker has a permanently attached 10 ft cable that terminates in an 1/8" plug. The loudspeaker has a part number SH2P4 printed on it in large letters. I paid $5 at two different hamfests, and nearly twice that for those I found online. This makes a nice, low profile, extension loudspeaker for any ham rig, and it's plenty good enough for use with a K2 if the background noise level is not extraordinarily high. It would make a nice extension speaker to sit on the dash of a car, for example, where the K2 was at a greater distance.
