Casiotone AS1000. Amplified speaker.
This is a simple, easy to understand, useful amp. You can hook up microphones, keyboards, mixers, mono signals. It has line out, and headphones jacks. I am not sure of its output power, Maybe 50 watt, maybe 100 watt. It has a tweeter, and a 10 or 12 inch woofer.
It is kinda rare, and collectable, not a lot were built. $300.00
Sears speakers. A pair of big ones with 15 inch woofers. These were probably some of sears best speakers ever. They are each 8 ohm. They can handle 100 watts each. $150.00 pair.
Kustom DWN-PS10 stereo subwoofer, with cover. This has a dual voice coil, 10 inch woofer. It works with an amp, it is not self powered. It handles 100 watt left and right, or 200 watt mono. $150.00
