The Genelec 7370 APM is a subwoofer designed to deliver powerful, transparent bass in the control room. The rear panel features a wide range of analogue and digital connections, along with various adjustment options for seamless integration into virtually any setup. In addition to XLR inputs and outputs and an AES/EBU connection, the subwoofer also features a network port, allowing comprehensive configuration for stereo and multichannel systems via the Genelec Loudspeaker Manager (GLM) software. Sonically, the Genelec 7370 APM delivers clean bass reproduction down to 19Hz with very low distortion. These features combine to make the subwoofer a professional solution for modern studios, particularly in multichannel audio production.
The built-in subwoofer measures 305mm/12" in diameter and is housed in a specially developed Laminar Spiral Enclosure (LSE) bass-reflex cabinet. It reproduces frequencies from 19 up to 100 or 150Hz in the LFE channel, and is powered by a Class D amplifier delivering 400W. An electronic system protects the driver against overload and short circuits, and the amplifier against thermal overload. A maximum sound pressure level of 113dB SPL can be achieved. Six analogue XLR inputs and outputs located at the rear of the device allow the connection of up to seven speakers for a multichannel setup. Settings such as crossover slope, phase, and signal gain can be carried out directly using the DIP switches.
The Genelec 7370 APM is aimed at professional studio operators seeking an effective subwoofer for their audio productions. Thanks to its SAM (Smart Active Monitor) DSP system, the subwoofer can automatically calibrate itself to the room's acoustic conditions, intelligently adjusting frequency response, level, and phase alignment for perfectly optimised sound in the control room. An optional measurement system is required for calibration, which can be carried out using either the Genelec GLM Kit or the Genelec 9320 Reference Monitor Controller. The software also allows Intelligent Signal Sensing to be enabled, reducing power consumption to just 0.5W in standby mode. Despite its weight of 48kg, transport is made easier by the elegant cabinet design, which features two integrated support bars.
Genelec was founded in 1976 by Ilpo Martikainen. It grew from a family business into one of the world's leading manufacturers of professional studio and broadcasting loudspeakers. To this day, Genelec's loudspeakers are manufactured exclusively in Finland. Genelec offers performance-oriented, neutral-sounding loudspeakers and subwoofer systems for audio professionals and sound enthusiasts, and a combination of innovative technology and design ensure that the range of products is continuously improving. The company is committed to sustainable development and environmental awareness. In 2018, Genelec was awarded the Pro Sound "Company of the Year" award. Genelec speakers are favourites of such recording industry veterans as Obie O'Brien, Michael Carnes, and David Reitzas, as well as of producers like Hardwell, Keith Ross, and Vini Vici.
Since low-frequency vibrations significantly affect room acoustics, careful placement of the subwoofer in the control room is essential, especially for models capable of reproducing frequencies as low as 19Hz. For optimum performance, the distance between the Genelec 7370 APM driver and the front wall should be less than 0.6 metres, as this can increase both the subwoofer's acoustic output and its maximum sound pressure level. Placing a carpet underneath the subwoofer helps absorb room vibrations. Using the manufacturer's GLM software, the frequency response should be adjusted to be as linear as possible. If further improvements in the frequency response's linearity are required, it may help to shift the subwoofer slightly to the left or right. Accurate placement can be achieved using the 85Hz test tone.
