JBL STAGE A120P

Active subwoofer with 12" woofer and 250 W amplifier power

The physiology of the human ear's perception of sound implies that for proper presentation, theof low frequencies requires much higher power than for mid and high frequencies. The ability to transmit the lowest frequencies is thus always proportional to the size of the loudspeaker diaphragm and the internal volume of the cabinet. It is therefore virtually impossible for speakers of smaller dimensions to carry the lowest bass frequencies. The solution is to add an active subwoofer (a special speaker for reproducing only the lowest bass frequencies) to the audio system. Here again, acoustics and the physiology of sound perception by the human ear, which very precisely locates the direction from which the higher frequency sounds come. The high frequencies propagate as a narrow beam, for the middle frequencies the narrow beam becomes a cone and the low bass frequencies propagate spherically. This means in practice that for low frequencies up to about 100 Hz we cannot tell where they are coming from. Therefore, it is possible to place a subwoofer almost anywhere in the room.

With the new JBL STAGE range of loudspeakers, you have a reserved seat in the front row.

JBL Stage is a sophisticated line of loudspeakers designed and engineered at the world-renowned acousticEngineering Center in Northridge, California (USA) and optimized for home stereo/home theater. JBL products can be found in many cinemas, studios and music halls around the world.JBL is a pioneer in the field of professional audio and thus certainly has the best facilities, development and technology to address the lowest frequencies.

The use of an active subwoofer from the JBL STAGE series will be beneficial both in a conventional stereo audio system and when integrated into a home theatre system. Each time it takes bass to a whole new level and adds another dimension to the experience of listening to music or watching action movie scenes. All right in your living room.

A120P - Active Subwoofer - ideal for use in medium and larger rooms.

An active subwoofer has an indispensable function in any system, but sometimes it can be difficult to find a suitable place for it.The JBL Stage A120P measures just 37cm wide, so you can place it where space is limited.Although its small size can make the A120P very inconspicuous in a room, this is certainly not true of its performance.A 12" (305 mm) woofer with a solid polycellulose diaphragm drives a 250 W RMS amplifier (up to 500 W at peak), and that's thehand that you'll actually hear the bass as the sound engineer mixed it in the studio - with authentic power you'd usually only feel in a cinema or live concert. The bass will always be well-controlled, tight and distortion-free.

The heavy-duty cabinet is built to withstand internal resonances, and there are two bass-reflex outputs on the back in addition to the amplifier controls. The speaker is front-facing, and a grille made from a well-sounding fabric is included. The finish is a textured matte black vinyl.Also included are 4 screw-in feet (spikes) and a power cord.
