I am using the speakers from West Mountain Radio mentioned several times in this thread and others regarding speakers. I find they have a nice cut for ham radio, at least for my ears and setup. Reducing highs are cut nicely and they have a good response for even dx if I pick up the volume on weak signals. But like you Jim, if I'm prepared for weak and crowded conditions, my headphones are on.
Then only issue I have with the West Mountain speakers is that the volume is unbalanced a bit. The primary speaker (the one with the power and controls) is louder - noticeably. This isn't an issue for simplex QSOs but has me adjusting the volume/balance for split operations and diversity. These speakers have no balance control. Not sure if this is my pair or a characteristic of this design.

As an audio pro, I have a few observations. The speaker amp in the K3 is a fairly small one, so outboard speakers should be either fairly efficient or should be amplified. Most home stereo speakers have fairly LOW efficiency, but most speakers for use in public address systems, and most speakers designed for communications use have fairly HIGH efficiency. For most serious operation I use headphones, but for casual operation I use outboard speakers. On the radio I use the most, they are a pair of very efficient, very good pro speakers that have long been discontinued. On the other radio I have a couple of miniature cube speakers designed for communications use. They all work fine. Voltage sensitivity is expressed as dBSPL for one watt at one meter, or for 2.828 volts. The most efficient small speakers you're likely to find will have this spec in the high 80s. SPL is Sound Pressure Level with respect a standard acoustic reference level. In the near field, sound decays at 6dB per doubling of distance, so at 1/4 meter, it will be 12dB louder than that number with a one watt sine wave, about 10 dB less with speech. 73, Jim Brown K9YC. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
