Introduction

The SP3 is a high-quality, front-facing speaker that complements Elecraft's K-Line both aesthetically and
functionally. It can be used with any receiver capable of driving a 4-ohm load. The speaker is passive (non-
amplified), ensuring no susceptibility to RFI in the present of a transmitted signal. The SP3's custom-built,
wide-range driver has excellent sensitivity and deep bass response.
The A/B switch on the front panel of the SP3 can be used to select one of two mono sources. Further, when used
in conjunction with a second SP3 this switch can be used to select one of two stereo sources. The Elecraft K3
and K3
transceivers take full advantage of this feature, since both provide rich binaural audio effects (AFX), as
S
well as user-adjustable left/right balance between main and sub receiver audio.
Rear-panel input jacks accept either mono or stereo cables, simplifying station wiring. An output jack is
provided for connection to a second SP3. When two SP3s are used, the A/B switch on the first unit controls
source selection for both.
