4. Torolàlana fananganana

4.1 Fametrahana

For optimal bass response, place the JRX218S subwoofer on a stable, flat surface. Corner placement can often enhance bass output, but experiment with different positions to find the best sound for your environment. Ensure adequate space around the unit for proper ventilation.

4.2 Fifandraisana

The JRX218S is a passive subwoofer and requires an external amplifier. Connect your amplifier's output to one of the SpeakON inputs on the rear panel of the subwoofer. The two SpeakON inputs are wired in parallel, allowing for easy daisy-chaining to another passive speaker or subwoofer. Ensure your amplifier can safely drive a 4-ohm load.

4.3 Fametrahana tsato-kazo

The subwoofer features a top-mounted, cast aluminum 35 mm pole mount receptacle. This allows you to mount a mid/high speaker cabinet directly above the subwoofer using an optional SS3BK pole (sold separately), creating a compact and integrated full-range sound system. Ensure the pole and mounted speaker are stable and secure.

5.1 Fitantanana hery

The JRX218S has a continuous power handling capacity of 350 Watts and a peak power handling of 1400 Watts. It is crucial to match your amplifier's output to these specifications to prevent damage to the subwoofer. Overpowering or underpowering can lead to poor performance or component failure.

5.2 Impedance and Frequency Response

The subwoofer operates at an impedance of 4 ohms. Its frequency range is 34Hz-250Hz (-10dB), with a frequency response of 53Hz-250Hz (±3dB). This range is optimized for deep bass reproduction.

5.3 Fampidirana ny rafitra

When integrating the JRX218S into a larger PA system, use an external crossover to send only low-frequency signals to the subwoofer. This ensures efficient operation and prevents the subwoofer from attempting to reproduce frequencies outside its optimal range, which can lead to distortion and reduced performance.

The rugged enclosure is constructed from 19 mm (.75 in) Medium Density Fiberboard (MDF) and covered in black carpet. The 18-gauge perforated steel grille protects the speaker components. Inspect these periodically for any signs of damage. Minor scuffs on the carpet can often be brushed out. Do not attempt to remove the grille unless you are qualified service personnel.
