The Genelec 7050B subwoofer is designed for stereo or 5.1 multi-channel systems, featuring a patented Laminar Spiral Enclosure, 70-watt Class D amplifier, room compensation controls, and bass extension down to 25Hz at up to 100dB SPL

The 7050B subwoofer is built for compact or home surround systems of any kind, as well as being the perfect complement to Genelec 8020A or 8030A monitors. It features an 8” driver, 70W amplifier, 5.1 XLR I/O, including five main input channels and an LFE channel with selectable 85/236Hz reproduction. The 7050B features patented Genelec technologies for enhanced low-frequency performance, including the Laminar Spiral Enclosure (LSE), a spherical design that allows for a longer bass reflex tube and turbulence-free port, which enable the 7050B to produce enhanced, precision bass extension down to 25Hz. With a built-in, highly efficient, 70W Class D amplifier, the 7050B can crank out a powerful 100dB SPL in contrast to its compact dimensions. Not just for 5.1 multichannel formats, the Genelec 7050B is also quite adept at handling low-frequency chores for stereo 2.1 systems, while providing the opportunity to move up to 5.1 without re-investing in quality subs.

INSIDE THE BOX—Genelec 7050B LSE Subwoofer

Laminar Spiral Enclosure bass reflex cabinet

 To meet the challenges of modern bass-heavy production requirements, Genelec took point to lead the industry in new technologies for superior bass reproduction. Enter the LSE series subwoofers, which feature the patented Laminar Spiral Enclosure (LSE) bass reflex cabinet. The LSE is a spiral-shaped design that yields an extremely rigid enclosure exterior, simultaneously forming the subwoofer’s integral port, which allows unrestricted air flow through the port.

The design of the cabinet enables it to house a very long reflex tube in a small space with minimal turbulence. It provides excellent laminar flow characteristics, which is a flow of air columns at the same speed with minimal, or no crossover of air streams, as opposed to a turbulent flow that can create noise and disturbance in the low-frequency range. The results are an extraordinarily accurate and responsive low-frequency system with second- and third-order harmonic distortion measured lower than 30dB below the fundamental.

When combined with Genelec stereo and multichannel bass management active electronics, the LSE Series subwoofers provide a dramatic low-frequency listening experience.

Bass management system

The principle of bass management is to limit the low-frequency range to loudspeakers able to handle it, whether its integral in the system or external.

A Bass Management system uses either analog circuitry or software-based filtering to separate low-frequency signals from the main channels and route it to one or more subwoofer feeds. The dedicated Low-Frequency Effects (LFE) channel heard via subwoofer is also be added to the low frequencies of the other main channels. As such, the Bass Management System’s goal is to ensure that the entire audio bandwidth of all channels can be accurately monitored.

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 to evaluate the audible impact of the subwoofer

Room-response compensation controls

All Genelec monitors feature analog room-response adjustments to compensate for acoustic room characteristics to achieve a flat frequency response at the listening position. Room response controls include (depending on model), bass roll-off and tilt, treble roll-off and tilt, bass level, midrange level, treble level, and desktop control.

Optimized Class D amplifiers

Active monitors, as opposed to powered monitors, use active crossovers, which electronically splits the audio into separate frequency bands. These bands in turn can routed to individual, highly efficient Class D power amplifiers, which drive transducers optimized for each frequency band. The active design offers several benefits. By connecting power amps directly to the drivers, damping control on the driver’s voice coil is maximized, reducing unwanted changes in the driver’s electrical characteristics, which can improve transient response. Active technology can produce superior sound output vs. size vs. low-frequency cut-off performance. All monitors comprise a factory-aligned system (amplifiers, crossover electronics, and enclosure-driver systems).

Active crossovers

Active crossovers come in both digital and analog varieties. Genelec digital active crossovers include additional signal processing, such as driver protection, delay, and equalization. The flat frequency response of a high-quality active loudspeaker is a result of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.

Using the active approach enables frequency response adjustments and optimization of the full loudspeaker system, placed in various room environments, without expensive external equalizers. The end result is a simpler, more reliable, efficient, consistent and precise active loudspeaker system.

Protection circuitry

Maintaining reliable performance in the studio is essential, which is why Genelec builds protection circuitry into the 7050B. With signal level detection, it prevents driver failure by reducing signal level automatically in case of sudden peaks or constant high levels.

Protection circuitry features and benefits:

  • Reduces the output level when required, (e.g. when driver voice coil temperature reaches the safe limit) which significantly improves system reliability
  • Protection circuitry specifically optimized to each loudspeaker and subwoofer enables maximum system output levels

OUTSIDE THE BOX—Genelec 7050B

The cabinet of the 7050B embodies sustainability and green values in its efficient use of materials, low-energy consumption, and extremely long life time. The rear panel has 6 balanced right XLR inputs (1x LFE, 5x main) and five XLR outputs, universal IEC mains connector for global use, and phase-matching and bass roll-off control for calibration to all acoustic spaces.

The Genelec 7050B subwoofer is designed to complement Genelec 8020/8030 monitors for small but serious stereo or 5.1 surround studios. For more information, call or chat online with your Westlake Pro Sales Consultant today.
