Wonderful problem.
Logitech design X-540.
5 speakers surround audio plus subwoofer. Has a convenient switch station with volume knob, bass knob, headset jack, and also power and matrix mode buttons.
Calls for 3 3.5 mm jacks (front, back, as well as sub/center). More than likely to be colored green, black, and orange/pink on your device. If you don't have any of those cables I could market you 3 for $10 or $5 each.
Can fall off between Wilson Creek as well as West Sechelt.
