Frequently Asked Questions
Active subs often offer more features and potentially higher power, but the JRX 218S provides a reliable, cost-effective passive solution needing an external amplifier.
Absolutely; birch plywood provides a stiffer and more resonant enclosure than cheaper MDF, contributing to a cleaner and more defined bass response.
Given the 4-ohm impedance and 350W rating, a quality amplifier delivering around 400-600 watts RMS would really let this sub shine.
