Presently, it uses the same feet as the KX3 and PX3, and the same style rear leg as the KX2. It is the same height and depth as the KX3 and PX3. There is one power port for charging the internal lithium battery, and input and output stereo jacks. The speaker is mono. The output jack redirects the right channel from the stereo input for a second speaker, just like with the Elecraft SP3 and other similar external speakers. The speaker is amplified.

> The SPX3 amplifier puts out a maximum of 5W into a 10W speaker driver, and is about as loud as any external radio speaker gets. Volume is adjusted by the KX3 and by the volume knob on the SPX3. The volume knob also turns it on and off. It plugs into the KX2/KX3 PHONES jack. There is a built-in band pass filter to reduce noise and improve the listening experience.
