Wide Contemporary

Wide Rectangular Space

This large multi-function space serves worship, conferences, and other musical events.

This larger space requires a larger array to focus sound over a longer distance. Equally important, the higher directivity minimizes amplified sound striking surfaces other than the audience to preserve music and speech clarity. The Side and Top views above show a main line array of (7) IV6-1122's that provide much of the coverage to the entire space. Two smaller curved arrays of (3) IV6-1122/15's cover the forward left and right audience spaces. Subwoofers are shown flown vertically stacked behind the main array to deliver coherent bass summation and extension. The elevated position consumes less floor space and bass covers more evenly. They can also be distributed evenly along the perimeter of the platform.
Six (6) IV6-1122/05 and one (1) IV6-1122/15 (Main array)
The main array covers the center. rear and part of the side seating. 
Three (3) IV6-1122/15 (x Two)
(Symmetrical right and left forward audience coverage)
One tightly curved array on either side focused on the outside 
forward congregational areas. 
Four (4) IV6-118S (Deep bass
Vertically flown behind the main array.


For maximum system performance and longevity, the loudspeakers must be properly powered to achieve the needed sound pressure level (SPL) in the listening area.  Refer to the product spec sheets for appropriate amplifier ratings.


To properly process, equalize and protect the loudspeaker systems, it is recommended to use the Community dSPEC226 digital signal processor.

Some amplifiers have built-in processing which may be adequate when properly programmed. Community's suggested DSP settings can be found HERE.

All of the loudspeakers require an electronic high pass filter for protection against over-excursion from bass-heavy program material.

Loudspeaker protection on the dSPEC226:
Protection is handled by three stages of protective limiters: these include a short-term peak limiter to prevent over-excursion of drivers and to control amplifier clipping; a mid-term RMS limiter that prevents system overdrive; and a unique long-term power monitor that works to protect your loudspeakers from long-term thermal damage.  All three limiters operate interactively, providing unique driver protection, while allowing each loudspeaker’s full dynamic range to be utilized without compromise.



When considering the distance between the amplifier and the loudspeaker(s), the following minimum cable gauges are suggested.

Less than 50 feet: 14 AWG
50 to 100 feet: 12 AWG
100 to 250 feet: 10 AWG

It is strongly recommended that all loudspeaker level wire be stranded, twisted and never shielded. Loudspeaker wires should not be connected to earth ground or supporting structures.
