[Elecraft] Looking for KX3 external speaker suggestions

[Gary]

Hi Wayne,
A while back I found a used Roland Mobile Cube stereo amplified portable
speaker set at the TRW swap meet ($5) and to my surprise it works pretty
well as a laptop amp, portable PA (mic needed), or as a mono or stereo amp
for just about any mic or line level driver (including radios like the K3).
Take a look at;

They're often available new and used on Ebay. The 1/8" stereo phone plug
input (AUX input) has no level control so the volume must be controlled by
the source. Another solution is to use an adapter cable and feed the main
mono or stereo inputs (Amazon, CMP153, $5). This port not only offers level
control but also has some special effects available. The Mobile Cube runs on
either 6 AA batteries or an external 9Vdc source.

Hi all,
Those of you who have seen the KX3 in person may have noticed that we  
use it with two external powered speakers, plugged into the headphone  
jack. We do this to emphasize how good the KX3's stereo audio effects  
are. (And of course it's so noisy at most hamfests that the small [but  
hi-fi] internal speaker can't be easily heard; it's intended for a use  
in a quiet shack.) Audio effects include simulated stereo, left-right  
pitch mapping, and dual-watch. These can only be heard with two  
speakers or when using stereo headphones/earbuds. Trust me, you'll  
never go back to mono :)
We've tried a couple of different Sony powered mini-speakers from Best  
Buy. Both had batteries but could also run on external power either  
from a PC USB port or from a small power adapter.
If you have some favorite small speakers you've used with a laptop or  
other radios, please send me the manufacturer and model numbers. Small  
is OK as long as the sound quality is good. Also, they shouldn't cause  
RFI.
For mobile--another very high-noise situation--you'll have three  
alternatives for getting car-filling audio: 12-V powered speakers, a  
modulator to rebroadcast the KX3's audio on an FM radio, or (my  
favorite) a stereo aux input to the vehicle's audio system. The latter  
is very common on newer models. If you know of some decent 12-V  
powered speakers, please let me know.
