Beefed up low-end from this 2-way box!
This amazing dual 15″ 2-way speaker functions as a quasi 3-way: the upper woofers cover lows and mids, and the lower woofers are crossed so they only cover lows-acting as built-in subwoofers. Progressive Transition WaveGuide horn design for enhanced high-end performance and SonicGuard circuitry to protect driver voice coils from feedback and clipping damage. Built with American-made JBL drivers, beefy JBL crossovers, roadworthy MDF cabinets, heavy-duty recessed handles, curved steel grilles, and rugged carpet covering. The JRX100 speakers are built to withstand the rigors of constant touring while delivering renowned JBL sound night after night.

SonicGuard circuitry to protect driver voice coils from feedback and clipping damage is not what it’s cracked up to be. Just set the gain right, match the RMS power to the amp and go.
The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp.
Here is a guide that will help you set the gain correctly
You’ll need a multi-meter (AC voltmeter), Microsoft Excel and a way to burn an audio CD from an MP3.
