Genelec 7050A Active Subwoofer

General description

Genelec 7050A active subwoofer is a very compact low frequency loudspeaker, designed to extend the bass reproduction of Genelec 1029A, 2029A or 2029B active monitors in stereo applications. Adding the 7050A to a 1029/2029 system creates a com- pact nearfield monitoring system capable of a flat frequency response from 38 Hz to 20 kHz (± 3 dB).

Driver

The 7050A contains a single 200 mm (8”) magnetically shielded low frequency driver, housed in Genelec Laminar Spiral Enclosure TM (LSETM).

Crossover

The active crossover contained within the amplifier unit filters the input signals. This accurately rejects the higher frequencies that the monitors reproduce, and allows the lower frequencies to pass. The sensitivity can be attenuated from 0 dB to -18 dB for easy level matching with the main loudspeakers. Due to the input sensitivity of the 7050A subwoofer it can only be used with Genelec 1029A, 2029A and 2029B active monitors.

Amplifier

The amplifier produces 70 W of output power, with very low THD and IM distortion. Driver

overload protection and power-on signal muting is included in the amplifier circuitry. The amplifier also incorporates thermal over- load and short circuit protection.

Installation

The subwoofer is supplied with a mains cable, signal cables to go between the main monitors and the subwoofer and this operating manual. Once unpacked inspect the subwoofer to ensure that it has not been damaged in transport. Check that the mains voltage selector switch is set to your local mains voltage (Subwoofers sold in Europe have a fixed 230 V setting). Ensure that both the subwoofer and the main monitors are switched off before making any connections.

Audio connections to the subwoofer are made with balanced 1/4" Jack / XLR cables supplied with the subwoofer. Signals from the source are fed to the XLR input connectors of the 1029A/2029A/2029B monitors. The 7050A gets its input signal from the 1/4" Jack "SUB OUT" output connectors of the the 1029A/2029A/2029B monitors (see Figure 1). When used in conjunction with the 7050A the "BASS ROLL-OFF" dip switch (switch 2) on the 1029A/2029A/2029B should be switched to position "ON". Once all connections have been made, the subwoofer and main monitors are ready to be powered up.

Positioning in the room

The placement of the subwoofer in the room affects the overall frequency response and sound level of the system dramatically, as at low frequencies the effects of the room are strong. Even a slight change in the subwoof- er's location can make a marked difference in the frequency balance and often a patient and methodical experimentation and testing is needed to find the optimum placement. The placement will affect the phase difference between the main monitors and the subwoofer and the bass roll-off rate.

First place the subwoofer slightly offset from the center of the front wall. The recommended distance to the wall is less than 90 cm / 36" measured from the subwoofer's driver. This position gives increased acoustic loading (and SPL) due to the proximity of the front wall and floor. Cancellations from the front wall and floor are also avoided. Front wall cancellation for the 85 Hz high pass filtered main speakers can be eliminated by placing them at least 110 cm / 43" away from the front wall (see Figure 2).

If the frequency balance does not seem right, try moving the subwoofer slightly to the left or right so that different room modes are excited at different levels. Positioning the subwoofer close to a corner will boost

7050A specifications

The Genelec 7050A is a compact subwoofer that has become a staple in both professional audio studios and home listening environments. Renowned for its exceptional performance and reliability, the 7050A provides deep, accurate bass reproduction that enhances any audio production setup. This subwoofer is designed to seamlessly integrate with Genelec's range of studio monitors, making it an ideal choice for those seeking to achieve a complete and balanced sound field.

At the core of the 7050A's performance is its advanced technology, which includes a 10-inch woofer powered by a highly efficient Class D amplifier. The combination of a robust amplifier and high-quality driver ensures controlled bass response with minimal distortion, even at high volume levels. This feature is particularly beneficial for mixing and mastering applications, where clarity and precision in the low frequencies are crucial.

One of the standout characteristics of the Genelec 7050A is its ability to adapt to different acoustic environments. The subwoofer is equipped with Genelec’s proprietary Intelligent Signal Sensing (ISS) technology, which allows it to automatically enter a low-power standby mode when not in use, conserving energy without compromising performance. This innovation is especially useful for long mixing sessions or when the studio is not in active use.

Furthermore, the 7050A features innovative room correction capabilities through its advanced acoustic design. The subwoofer is equipped with a built-in microphone that can measure the acoustics of the environment, allowing for optimal adjustments to ensure a balanced bass response regardless of location. This technology helps prevent common issues such as phase cancellation and frequency anomalies, resulting in a more accurate sound reproduction.

Connectivity is another highlight of the Genelec 7050A. It provides multiple input options, including balanced XLR connectors, which enable easy integration with various audio sources and mixing consoles. Additionally, the subwoofer allows users to customize the crossover frequency to suit their specific monitoring needs, ensuring compatibility with different monitor systems.

Overall, the Genelec 7050A subwoofer encapsulates an exceptional blend of advanced technology, innovative design, and practical features that cater to audio professionals and enthusiasts alike. Whether used in a studio or a home environment, it offers a powerful and dynamic bass response that enhances the overall listening experience.
