Genelec Speaker System w/ 1038b Pair and 7071a Sub (Used)

Genelec's 7071A dual Active Subwoofer is powerful and precise bass monitoring tool for modern 6.1 or 5.1 channel Surround Sound or traditional stereo systems. With its 19 Hz lower cut-off frequency, high sound pressure output capability and versatile bass management systems, it can be adapted to all low frequency monitoring situations.

The amplifier unit integrated into the cabinet contains active crossover filters, driver overload protection circuits and power amplifiers. The in-built bass management unit has six signal input and output channels, summed signal output connectors and LFE input equipped with a selectable 85/120 Hz lowpass filter and a 0 / +10dB LFE sensitivity switch.

The Genelec Laminar Spiral Enclosure (LSE) bass reflex cabinet is made of a sheet metal rolled into a spiral shape and clamped between thick MDF side panels. This new construction technique 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 Genelec 1038B is a three-way active monitoring system including loudspeaker drivers, speaker enclosure, multiple power amplifiers and active, low signal level crossovers. Designed for medium sized control rooms this system is ideal for project studios, film and video post-production and broadcast monitoring. CD mastering is also tailored for, where broad bandwidth, high SPL's and extended low frequency response are essential. The 1038B is designed to perform well both as a free-standing monitor and flush mounted into the control room wall.

The unique Directivity Control Waveguide (DCW) Technology used provides excellent stereo imaging and frequency balance even in difficult acoustic environments. The fast, low distortion amplifiers are capable of driving the stereo system to peak output levels in excess of 124 dB SPL at 2 m with program signals. Versatile crossover controls allow for precise matching of the speaker system to different acoustic conditions. The system can be used both in vertical and horizontal orientation by simply rotating the DCW unit

INTEGRATED CONSTRUCTION

The system is very easy to use as only mains power and input signal are needed. Uniform performance is obtained through the integration of the loudspeakers and amplifiers as a complete matched and calibrated package. The rugged amplifier is mounted into the enclosure with vibration isolators which also act as quick release hinges making maintenance operations easy and straightforward. The speaker cabinet is constructed of veneered MDF, which is heavily braced to eliminate structural resonances.

AMPLIFIERS

The bass, midrange and treble amplifiers each produce 400W, 120W and 120W, respectively of short term power with very low THD and IM distortion. Special attention has been paid to electronic design to ensure the highest subjective sound quality currently possible. The system incorporates special circuitry for drivers overload protection. Thermal protection is also included for the amplifiers.

CROSSOVER FILTERS

The crossover frequencies of the active crossover network are 410 Hz and 3.0 kHz. In order to obtain uniform frequency balance under different acoustic conditions, special calibrated controls are included in the crossover. The Bass, Midrange and Treble level controls operate in 1 dB steps. Furthermore, the low frequency Tilt and Roll-off controls both have four 2 dB steps to allow refined LF response tailoring. A high-pass filter is included in the LF channel to protect the woofer from subsonic signals. The crossover network is driven by an active balanced input stage, fed by a 3 pin XLR. Variable input sensitivity allows for accurate level matching to the mixing console.

DRIVERS

The bass frequencies are reproduced by a 385 mm (15") bass driver loaded with a 110 liters vented box. The -3dB point is 33 Hz and the low frequency response extends down to 29 Hz (-6 dB). The midrange frequencies are reproduced by a proprietary 130 mm (5") direct radiating cone driver loaded with a DCW. The high frequency driver is a 25mm (1") metal dome also loaded by a DCW. A factory-installed magnetic shielding option is available for applications where magnetic stray field must be minimized.

DCW TECHNOLOGY

The revolutionary Directivity Control Waveguide Technology is a means of vastly improving the performance of a direct radiating multiway loudspeaker in normal listening conditions. The basic idea is to match the different drive units precisely, both in terms of frequency response and directivity. This will result in a smoother and a virtually uncoloured off-axis response of the system. Also due to improved directivity control especially in the midrange frequencies, more direct sound and less early boundary reflections are received at the listening position. This gives more accurate stereo imaging and makes the system less sensitive to differing control room acoustics than any conventional direct radiator design. The DCW Technology improves drive unit sensitivity from +2 to +6 dB thus increasing the system maximum sound pressure level. The tweeter and the sealed midrange driver are mounted on a DCW to match their dispersion characteristics. The DCW can be rotated for horizontal mounting.
