Genelec 7370A PM Subwoofer

Genelec 7370A SAM Subwoofer (P)

The Genelec 7370A SAM subwoofer is a powerful 400-watt subwoofer with a 12" driver and software management control, built to complement Genelec 8000-series and 1032C SAM active monitors in multichannel and stereo applications - Producer Grey finish.

The Genelec 7370A is a highly intelligent 12" subwoofer built to complement the Genelec 8000 series smart monitors. The next step up in size from the compact 7360A, its built-in Smart technology allows its more powerful 400W optimized amplifier to fill a mid-size room with bass, while effectively negating the highly kinetic reflections smaller spaces are prone to. The 7370A features Genelec's Laminar Spiral Enclosure (LSE), which combines form and function to provide a noise-free reflex port that's integrated into the enclosure, resulting in deep bass extension and clean, articulated low-frequency reproduction. It's also equipped with Genelec's proprietary bass management system and support for 7.1 multi-channel set-ups over analog XLR I/O, plus stereo AES/EBU XLR I/O - no need for external A/D converters. To save power, Intelligent Signal Sensing (ISS) puts the 7370A to sleep when no signal is present after a period of time. Additionally, Genelec Loudspeaker Manager (GLM) software allows for the fine adjustment of up to 30 individual Smart monitors and Smart subwoofers, while AutoCal compensates for room modes to perfectly calibrate your set-up to your listening environment.

Genelec 7370A - Behind the Grille

The compact Genelec 7370A smart active subwoofer extends the bass reproduction of Genelec 8000-series and 1032C smart monitors in stereo or multichannel applications. It can be used a general purpose Smart subwoofer solution with any analog or digital audio monitor. The 7370A contains one 12" low-frequency driver housed in a Genelec's proprietary Laminar Spiral Enclosure (LSE) bass reflex cabinet and a Class-D power amplifier that outputs 400 watts with very low THD (Total Harmonic Distortion) and IM (Intermodulation) distortion. The amplifier features driver overload, amplifier thermal overload, and driver short-circuit protection.

Networked Smart Active Monitor (SAM) Systems

Genelec's advanced SAM Systems can automatically adapt to acoustic environments and correct for levels, delays and room anomalies. SAM Systems can be controlled via Genelec proprietary Loudspeaker Manager (GLM) network and software, enabling you to build a highly flexible and reliable monitoring system. If the monitors have to move between rooms, you can rely on SAM technology to give you absolute consistency, a neutral soundstage, and low distortion. All electronics, drivers, and enclosures are designed, assembled, tested, and calibrated in Genelec's factory in Finland. Genelec quality and reliability ensure a secure long-term investment, with environmentally conscious, low energy consumption and outstanding audio quality.

AutoCal room calibration

Genelec AutoCal is a system integrator's dream and gets you out of stasis and into production faster. It facilitates setup by measuring acoustic response in the listening area and applying the appropriate compensation in the low and low-mid frequencies to minimize the muddying effect of room modes and other unwanted room resonances, while simultaneously accounting for the differences between various listening positions.

Laminar Spiral Enclosure (LSE)

An essential property of a subwoofer operating at high sound pressure levels is its capacity to move high volumes of air without distortion, which is a function of air turbulence inside the bass reflex port. This effect presents challenges to woofer and reflex port designs. Genelec's patented Laminar Spiral Enclosure (LSE) provided the solution.

By way of a little background, large air currents, such as those found in bass reflex ports, have a great deal of kinetic energy, which causes the flow to be irregular and turbulent as cross-streams perpendicular to the direction of air flow is formed. A laminar air flow is a streamline flow in which air travels smoothly in parallel layers or paths, with no interference or disruption across layers.  

The Laminar Spiral Enclosure (LSE) bass reflex cabinet provides excellent laminar flow characteristics with minimal turbulence noise and enables an optimal packing of a very long reflex tube into a small space.

The 7370A's enclosure is made from a spiral-shaped strip of steel. Its purpose is to provide mechanical stability for a large amount of pressure generated inside the subwoofer. The spiral also forms the bass reflex port, enabling linear airflow even at the highest SPL output. The fact that one is part of the other means that air flow in and out of the enclosure's interior through the port is totally unrestricted. This flow-optimized construction provides extended low-frequency capacity and low distortion resulting in precise bass articulation, with measured second and third harmonic distortion levels typically better than 30dB below the fundamental. This results in an extraordinarily accurate and responsive low-frequency system.

Bass management system

Bass management, from a corporate perspective, is the man's way of keeping the low frequencies down. Seriously, it's quite simply a means of directing the bass content of main and low-frequency effect (LFE) channels to the speakers that are best capable of handling them. A Bass Management system uses either analog electronic circuitry or software-based filtering to take low-frequency information from the main channels and route it to a subwoofer feed. Bass management's basic and main goal is to ensure that the entire audio bandwidth of all channels can be accurately monitored.

The bass management unit in the 7370A subwoofer splits the input into low- and high-frequency components at 85Hz. Frequencies below 85Hz are reproduced by the subwoofer. Frequencies above 85Hz are directed via the subwoofer's output connectors to the main monitors.

Bass management benefits are:

  • The subwoofer extends the system frequency response down the lower limit of the audible range
  • Monitor can produce a higher maximum sound level when not reproducing low frequencies
  • Optimized low-frequency reproduction by selecting adequate subwoofer location; monitors can also be placed more freely
  • Subwoofer's output are aligned in level and phase with monitors allowing flat and accurate reproduction down to 19 Hz and across the crossover point
  • LFE channel output level (0 or +10 dB re. main channels) can be selected for accurate reproduction depending on the source type
  • The ability to bypass the subwoofer allows you to evaluate the audible impact of the subwoofer

Optimized amplifier

A custom, Genelec-designed and manufactured Class D power amplifier connected directly to the driver produces 400W output power with very low total harmonic distortion (THD) and intermodulation distortion (IM). Driver-overload, thermal overload, and short-circuit protections are built into the amplifier circuitry. The power supply accepts mains voltages from 100 to 240 VAC.

The active design principle offers multiple benefits:

  • The power amplifiers are directly connected to the speaker drivers, maximizing the control exerted by the power amplifier's damping on the driver's voice coil, reducing the consequences of dynamic changes in the driver electrical characteristics. This may improve the transient response of the system
  • There is a reduction in the power amplifier output requirement. With no energy lost in the passive crossover filter components, the amplifier power output requirements are reduced considerably (by up to 1/2 in some cases) without any reduction in the acoustic power output of the loudspeaker system. This can reduce costs and increase audio quality and system reliability
  • No loss between amplifier and driver units results in maximum acoustic efficiency
  • Active technology can achieve superior sound output vs. size vs. low-frequency cut-off performance
  • All loudspeakers are delivered as a factory aligned system (amplifiers, crossover electronics, and enclosure-driver systems)

Intelligent Signal Sensing function

Genelec's Intelligent Signal Sensing (ISS) is a power-saving feature that prolongs the service life of the monitor. ISS reduces power consumption to less than 0.5 watts by automatically switching the active monitor to standby when no audio signal has been detected for some time. When playback begins, the mode indicator light on the loudspeaker lights up and the playback resumes after a slight delay (<2 seconds).

Protection circuitry

In the studio, downtime is not an option, particularly when equipment fails and must be shipped out for repairs. Whether you're working in a professional production environment or even as a hobbyist, it's essential that monitoring systems remain reliable and functional at all times. Genelec's reputation for bullet-proof reliability is a product of the internal protection circuitry found in all Genelec monitors.

The protection circuitry prevents driver failure by detecting signal levels and responding accordingly. In the case of sudden peaks or levels that are too high for long periods, the protection circuitry reduces signal level automatically. This feature does not affect the sound quality in any way when working within the specifications of the loudspeaker, but only prevents inappropriate input signals from breaking the loudspeaker.

Protection circuitry benefits:

  • Reduces the output level when required (e.g. when driver voice coil temperature reaches the safe limit), which highly improves system reliability
  • Appropriate protection circuitry design for each loudspeaker and subwoofer maximizes system output level
