set of two professional subwoofers
CORE Series 10218SA – Active 18″ Flyable High Power Subwoofer with DSP (Compatible with CORE102)
CORE Series 10218SP – Passive 18″ Flyable High Powered Subwoofer (Compatible with CORE102)
used but in good condition, however, i do not have interface capabilities (ie, RS485 or RJ45 ETHERNET and computer with software) to properly demonstrate.
if you have, including software on your computer to test, then great as i'd rather not sell unless i can demonstrate functionality in person. (price is for both).
