Kustom KPM10 powered monitors.
I have two of these for sale. Mint condition and hardly used. Can be used as monitors, or as an amp for guitar, bass, keyboards, or electronic drums. The specs are - 50-watt RMS, 2-way powered wedge stage monitor featuring a 10-inch woofer and a piezo high-frequency driver. It is designed for live performance, offering a, XLR/1/4-inch combo input, a dedicated volume control, and a "thru" jack for daisy-chaining multiple units. $70 each or $125 for the pair. Possibly open to trades. I've got other amps and music gear for sale as well.
