JBL STAGE 220P Aktīvais Sabvūferis (cena par gab.)

The JBL Stage 220P subwoofer features a 250W RMS amplifier and a larger 12-inch woofer than the Stage 200P, delivering deeper bass down to 26Hz. The polycellulose ribbed high excursion driver enhances cohesion whilst in play and reduces distortion for clearer sound. This allows for deeper, clearer bass response by enabling greater movement of air. You can customise your listening experience with adjustable crossover frequencies and controls for auto power, volume level, and phase.

Large 10” driver

The large 12” driver, in the JBL Stage 220P subwoofer, can move plenty of air for thunderous bass with movies and music. The cone is made of Ribbed Polycellulose. Normally speaker cones are made of paper pulp or cellulose. However, more modern materials such as polypropylene are also used.

Polycellulose combines the properties of both. As a result, there is less distortion and the cone is less susceptible to moisture. Lastly, the ribbing provides rigidity and a high excursion capability.

A quality resonance-free cabinet

Subwoofers produce a lot of power at low frequencies. As a result, the cabinet needs to be heavy enough to suppress vibration. It also needs to be well-braced and rigid to avoid resonances. As a result, the cabinet of the JBL Stage 220P subwoofer is made of audio-grade MDF and has extensive internal bracing. Next, there are two rear-firing bass ports. These extend the low frequencies down to 28 Hz.

Setting up a subwoofer

There are various setup procedures to follow with the JBL Stage 220P subwoofer. Firstly it is designed to go with AV receivers that have a line-level output. However, JBL also produces subwoofers that can take a speaker-level input. Firstly, the phase needs to be checked. There is a switch that can be used to change this. Set it so that the bass is enhanced.

If the phase is reversed the subwoofer will cancel out the bass from the main speakers. Next, set the level so that the subwoofer does not overpower the main speakers. Lastly, the crossover frequency can be set by ear. For example, Bookshelf speakers will have a higher cut-off frequency than large floor standers.
