Traditional Cruciform

Long Nave with Side and Balcony Seating

Large traditional church with a long nave and auxiliary seating in the transept and balcony areas.  The system should not detract from the architectural details, but needs to provide intelligible speech and clear music.  

To ensure clear speech delivery, ENTASYS ENT-FR line array column loudspeakers strategically surround the altar area to direct sound to the intended listeners. These highly directional loudspeakers minimize reverberation and microphone interference.
As a modular system, the ENT-FR modules can be stacked vertically to offer greater directivity over longer distances. Single ENT-FR modules, or the two-way point source ENT212, can extend coverage to the transept seating from two directions to ensure all areas are covered.
Use of advanced acoustics software (i.e. EASE® Focus), and careful positioning and aiming will allow the congregation to hear amazingly natural sounding speech content. Music amplified over this system will not only project more clearly, but can be played at higher tempo because it is less subject to the long decay times.

The balcony seating falls out of the nave system coverage and requires flanking ENT212 units with applied signal delay.  IC600 compact point source models mounted overhead are another option.

Transept seating is addressed by a pair of ENT-FR (or ENT212) units with applied signal delay.  Smaller transept areas can be serviced by smaller ENT200 models. 


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.
