BEC Akustik IC-120 Slim Line-Array Speaker

BEC Akustik IC-120 Slim Line-Array Speaker (Single)

The BEC Akustik IC-120 is the tallest model in the German brand’s IC Series, a family of passive line-array loudspeakers designed for rooms where a conventional box speaker would look out of place. The aluminium cabinet is only 37.5mm wide and 23mm deep, yet it stands 1206mm tall and carries four broadband drivers stacked in a vertical line. This listing is for a single speaker, so it can serve as one channel of a stereo pair, a centre or surround channel in a discreet home cinema, or a single coverage column in a speech and background music installation.

Arranging the drivers in a vertical line changes how the sound spreads. BEC Akustik rates horizontal dispersion at 160 degrees and vertical dispersion at 40 degrees, so output is fanned widely across the seating area while the vertical pattern stays controlled, sending less energy into the floor and ceiling. That pattern suits presentation rooms, houses of worship, retail and hospitality spaces, and living rooms where listeners sit along a row rather than at stacked heights, and it helps speech stay clear in rooms with hard, reflective surfaces.

Key features

• Four 20 x 120mm broadband drivers in a vertical line array
• Rated power handling of 40W, with a maximum rating of 80W
• Exceptionally slim aluminium cabinet, 37.5mm wide and 23mm deep
• Wide 160-degree horizontal dispersion, controlled 40-degree vertical spread
• Sensitivity of 88dB and a maximum rated SPL of 106dB
• Metal angle bracket mounting included

Drivers and operating range

The four broadband units together cover a rated frequency range of 120Hz to 20kHz at the minus 6dB points. BEC specifies two crossover approaches: the brand’s own passive crossover, or active operation with a Bessel 6dB crossover at 180Hz. Either way, the system design is the same. Cross the IC-120 over to a subwoofer above its low-frequency limit and let the array handle speech, vocals and musical detail, which is where this slim format performs best. With sensitivity of 88dB at 1W at 1m and a maximum rated SPL of 106dB, modest amplifier power produces useful levels in typical rooms.

Amplifier matching and cabinet

Impedance is rated at 4 ohms, so confirm your amplifier is comfortable driving that load before pairing them. Connection is via a Phoenix 2-pole input connector. The aluminium enclosure keeps the complete speaker down to 1.2kg despite its height, and across the IC range BEC produces black, white, silver and gold finishes, with in-wall mounting, a magnetic on-wall bracket, a stacking adapter and ceiling mounting available as options beyond the included metal angle bracket.

As a single unit, the IC-120 is a flexible building block: one column for a small presentation space, two for stereo, or several distributed around a larger room, each run from its own amplifier channel and supported by shared bass from a subwoofer. It is an installed speaker for people who want the sound present and the hardware nearly invisible.
