CoLine Loudspeaker System
[Co(Coaxial, Coincident, Coherent)Line™] Loudspeaker
The CoLine™ Loudspeaker is a Coaxial/Coincident 2-way full-range Line Loudspeaker System that solves coverage and reverberation problems in many applications. The selection of drivers, physical arrangement, and most importantly crossover configuration combine to make a multi-way loudspeaker system that behaves as a single driver. There are no detectable notches in the system response anywhere within the 160 degree horizontal coverage. The low and high frequency section phase and time domain behavior results in the low and high frequency driver outputs exactly overlaid for perfect impulse response. As a result speech is easier to understand and percussive musical sounds are reproduced with the same transient signature as they are produced. Musical texture is much closer to an un-amplified experience. All of the compromises that work to reduce the ideal performance of a loudspeaker system have been addressed in this loudspeaker system. The Line Array arrangement allows this loudspeaker system to provide high quality audio in acoustically hostile environments such as large churches, convention centers, large theaters and concert halls. In many cases delay zone loudspeakers far from the stage are not required. Use of this loudspeaker system can eliminate the need for acoustical treatment to reduce reverberation. This is a feature that is usually desirable in churches and concert halls.
Even though this loudspeaker system is compact it can generate 105db at 100 feet from the stage. And the horizontal coverage is more than twice as wide as a popular ribbon driver at frequencies above 2.5Khz. This means that more of the audience hears extended range audio.
Features, Benefits and Uses
Even front to back coverage of room. Listeners close to the CoLine™ Loudspeaker are not blasted while listeners far away hear at the same level that conventional loudspeakers produce less than halfway back in the room or better.
Dramatically reduced susceptibility to feedback because of Line Array arrangement. Use of the CoLine™ Loudspeaker allows much greater sensitivity and output with lavalier microphones compared to conventional loudspeakers. This feature is very desirable for theatrical performances.
Small footprint takes up very little space.
Tilt-back wheels allow for easy movement and placement.
Package includes amplifier(s), preset digital signal processor with proprietary crossover configuration and filters set to flat power response. Simply Plug & Play.
Coherent, Phase Aligned Crossover with coaxial driver arrangement provides very high reproduction quality and detail.
Touring Theater: Excellent choice for touring theater. Takes up very little downstage floor space and can be setup and aimed in almost no time. No custom steel cages to aim multiple speakers. No intelligibility reducing interference between multiple speakers because only one is typically required on each side of the stage.
Cinema: No matter what loudspeaker
system that you use the reproduced by the loudspeaker system is compromised
because of the crossover. Above and below the vertical centerline of the
speaker system there is a notch in the frequency response of the loudspeaker.
For a typical 500Hz crossed-over system, this notch creates a hollow sound in
speech range. This is due to the to crossover used and arrival time
differences between the Low and Mid/High drivers. Three-way systems don't
solve this problem. In fact they create two places in the audio
spectrum where this notching of response occurs. Just because the manufacturer
doesn't show this in their data sheet doesn't mean that the problem doesn't
The shallow depth allows for compact placement behind the screen.
Scalability; as the floor height front to back increases beyond the 76" height of the Coline model CL2-32 plus 5 degrees above and below the front of the CoLine Loudspeaker, additional modules are added to assure that all listeners ears fall between the bottom and the top of the CoLine Loudspeaker.
Local and Regional Sound Companies are often called on to supply a support package for High School and College Musical Theater. The Coline™ Loudspeaker is an excellent choice because it is easy to deploy as down-stage speakers, provides excellent sound even to the rear of a deep auditorium, and has less feedback potential than conventional loudspeakers.
