A different problem a different solution...
This discussion has involved a single rig (K3) and it's speakers. My
situation is different, but I suspect likely relevant to many.
When I ordered my K3 and settled in for the early order wait I spent a bit
of time (months) contemplating how to fit

Hello,
Well after 18 months the buzzing of the K3 internal speaker has
reached annoying proportions.
For a while it faded after switching on for 10 mins but now its a
constant resonance at 580 Hz. Great for CW! (not)
Because of the above I am sure its because the coil has shifted in the

Well I've always found that the K3 internal speaker is pretty lousy on
CW, OK with SSB. Not a big problem 'cos I always use phones for CW. I

the rear of the speaker to improve the sound. I've done all the factory

Hi Iain,
Glad someone else can spell the name properly ;)
The topic of external speakers has been beaten to death many times

May I suggest that you find a pair of efficient speakers rather than
just one. Even if you do not have the subRX, you can enjoy the
enhancement offered by the AFX effects.
I am not going to mention any specifics because I just don't know. If
you want shortwave listening in addition to

well enough for me for CW and SWL. They peak around 600-700 Hz. I
would prefer a little lower, 400-500 Hz, but they work ok in that
range. And no buzzing anywhere that

That may be true in terms of power gain, but there may be some value in
having the speakers front-firing instead of top-firing like the K3's
built-in speaker.
Another cheap/easy solution might be a PVC pipe 90-degree elbow sitting on
top of the rig to redirect the sound (mono only).

Andrew,
A right angle elbow might be one solution, but the K3 does have stereo
capability. Connect stereo speakers to the rear panel speaker jack and

I wasn't all that impressed with how the AFX sounded on headphones, so
I was surprised how much better it was on speakers, even the small
ones I have sitting on top of the rig with that minimal amount of
separation. Anyone who is considering getting an external speaker
should definitely get a pair
