• RBN401 pro-ribbon HF driver with exceptional intelligibility and throw
  • All Neodymium drivers for excellent performance-to-weight ratio
  • SIS pre-wired for very high damping and further reduced distortion (with ALC)
  • Maximum attainable gain-before-feedback
  • Durotect™ scratch-resistant coating
  • Extended headroom/SPL and protection in combination with SDP circuit (in ALC)
  • Passive filtering for easy operation and economical powering


LR7 The LR7 is a passive 2-way line-source loudspeaker system. It is a true line-array system, to be used as vertical array, either in stacked or flown configuration, for both portable and permanent installations. Loaded with the RBN401 pro-ribbon driver on a “Morpher” lens (up to 94% frontal radiation!), the system features 120° dispersion with seamless coverage, due to the ribbon’s all-natural cylindrical (Isophasic) wavefront. Its transient response and unusual high peak power handling (800W/200mS) caters for an amazing intelligibility and throw, while offering maximum “gain-before-feedback” up to directly under the array. 

The micro-sized design, combined with the weightsaving all Neodymium drivers, makes the system very easy to handle.

The “Morpher” is mounted in the “ALrad™” waveguide, which utilizes the stiffness and heat transfer capabilities of aluminium. Mounted on the RBN, the ALrad™ extends the cooling surface for even further reducing powercompression for increased SPL over time.

The SignalIntegritySensing™ pre-wiring ensures complete cable/connector compensation between the LR7 and ALC. Typical (short to medium throw) applications for the LR7 include as compact main system for theatre, A/V or corporate events where minimal sightline obstruction is required, with exceptional sound reproduction. It is available in 90° and 120° configuration.

In applications where extended bass response is required, the LR7 can be combined with a pressurebass or deep-sub system.

For full system performance, we recommend using the LR7 in combination with an ALC amplifier/controller. Driven by the ALC, the LR7 delivers maximum sound quality with inaudible (power and excursion) protection (SDP circuit). All LR7 system presets are included in the library of the Digital Drive Processor™; with which also array-length and positioning (stacked/flown) can be adjusted.
