INTRODUCTION
1 Introduction
Dear customer,
Thank you for the trust you have put in us by buying these speakers. You decided upon a quality
product that in regard to tonal and technical characteristics complies to the utmost expectations.
The usual burn-in period is not required, because the speakers are articially aged in-house.
Please read the technical description and manual to take advantage of the capabilities
of these speakers and ensure safe operation.

SYSTEM DESCRIPTION
3 System description
The RL 944K is a specialist for small rooms and short listening distances. So it is designed for both
the professional user in the outside broadcasting van, small audio, video and lm studios and for the
discerning music enthusiast, who is not willing to make a compromise in a small living room.
By the cardioid radiation characteristics within the frequency range from 35 Hz through 250 Hz
the reections on the back walls behind the speaker can be minimized. In addition the transfer
characteristic can be matched to the acoustical conditions of the reproduction room as well as to the
set-up situation by an integrated room matching lter.
The total directivity index of the monitor was optimized for listening distances between one and
2.6 metres (3′3″ and 8′6″). As the bass system a very linear 200 mm (8″) long-throw driver in a
cardioid cabinet is employed, delivering excellent impulse delity. Due to the special construction a
low frequency reproduction is possible that is not expected from such a small cabinet. Therefore the
3
RL 944K is a real full-range speaker and in an outside broadcasting van an additional subwoofer can
be spared. The 100 mm (4″) cone is mounted together with the 19 mm (3/4″) dome tweeter coaxially
in front of the bass system allowing a precise steering of the focal perspective. As a result a realistic
and steady spatial performance of the sound pattern around the listening position is achieved, with
high homogeneity and smallest possible coloration. By the great consequent optimization for short
listening distances the RL 944K allows realistic depth perception even in outside broadcasting vans
and facilitates correct miking. Therefore the RL 944K is a precision studio tool allowing fatigue free
working for hours.
The three-channel MOSFET power amplier with electronic crossover is integrated into the back
of the cabinet and is hinged for service purposes. An intermittent LED lighting signals when the
overload limit is reached. After crossing of the maximum level the output level will be reduced by
20 dB to avoid any overloading of the components.
The RL 944K1 is a more compact cabinet variant of the RL 944K, that is employed when not enough
room is available. Be it a video wall or an outside broadcasting van. As an alternative to the standardly
provided MOSFET amplier in an upright standing enclosure the 19-inch compatible Class-D amplier
RL-Amplier is also available.
A variety of special stands and racks is available as accessories. According xing elements have been
integrated into the loudspeaker cabinet.
