Stereo Speaker for K3

Am I missing something? Why would one want to use an amplified speaker on a
K3 since the radio already has an amplifier? Doing so would seem to invite
distortion and RF pickup. The K3's audio output is supposed to have a 4 ohm
load and computer speakers are probably closer to 1000 ohms. It's almost
like having no load at all. I don't think that's good for the K3's output
chip.

I have the West Mtn. speakers here and they sound rather poor compared to
almost any comparable computer speaker.

Steve -

I also am using West Mountain speakers, and am quite happy with them. Mine
are amplified. Are yours NOT?

I have WMR amplified speakers, and I get really bad sound if the volume is up too far.

That is probably the case here as well... but I guess I just don't run the
volume up very far.

Hi Steve,

I have used a pair of Motorola HSN4018C mobile radio speakers with my K3 for years, as well as now with my new K3S. They are tailored for communications-grade voice frequency response. They are black and look great next to the rig. They are not inexpensive if you order them new, but your local two-way radio shop will likely have these or something similar in the HSN series that were recovered during commercial mobile radio removals. You can often get a decent price on a pair.

73-

Terry, W0FM

However, make sure that they match in volume too. I've had two
identical speakers with one of them several db lower in volume
(fortunately I had more, so I used another). Both appeared to be in
near new condition. Once matched, outstanding. I've used them for many
years in mobile environs too, zero issues.
