LRC 1100
LRC Series
LRC-1100
One-meter passive column with switchable 20°/40° vertical coverage and integrated 70/100 V power — as installed in Shakespeare's church.
The LRC Series — Line Radiator Column — is built for installations where audio quality and clean architecture carry equal weight. Purpose-built 2.5-inch drivers sit behind proprietary PaSS phase plugs that control vertical dispersion, so energy lands on listeners instead of exciting reflective floors, ceilings, and walls. The paintable enclosure comes in RAL 9004 signal black or RAL 9003 signal white and mounts close to the wall on the SwifTilt bracket, which conceals cables and hardware.
The LRC-1100 doubles the driver count: twelve 2.5-inch drivers plus passive radiators in a 950 mm column reaching 65 Hz. Vertical coverage switches between 20° and 40°, with a 5° acoustic down-tilt built into the pattern, and the integrated 70/100 V transformer (taps to 120 W) carries patented Automatic Saturation Compensation. At Holy Trinity Church — Shakespeare's church — LRC-1100 columns keep energy off centuries-old stone in the chancel and choir stalls.
What the LRC-1100 brings
PaSS dispersion control
Twelve 2.5-inch drivers and passive radiators reach 65 Hz while holding a controlled vertical pattern.
Switchable coverage
20° or 40° vertical patterns with a 5° acoustic down-tilt aim the sound without visibly tilting the column.
SwifTilt mounting
Flush, pan, and tilt from one compact bracket: ±80° pan at every down-tilt angle, tilt to 25°, inverted mounting, concealed cables.
All-weather, certified
IP56c weatherized for full outdoor exposure, EN54 certified, paintable RAL black or white.
70/100 V + ASC
Integrated transformer with taps from 120 W down to 8 W; patented ASC guards electronics while keeping low-frequency response.
System-matched DSP
Dedicated presets for Dynacord DSP matrix processors and amplifiers, with EASE, PREVIEW, and SONICUE software support.
Case study
Heard in Shakespeare's church
Holy Trinity Church in Stratford-upon-Avon — where Shakespeare is buried — replaced an end-of-life 100 V system with an Electro-Voice and Dynacord solution. LRC-1100 columns in the chancel and choir stalls control vertical dispersion naturally, keeping energy off centuries-old stone while speech lands clearly in every pew.
