A complete L-Acoustics installation system built around A15i constant curvature line sources, with KS21i subwoofers and an X8i centre fill. A15i is the step up from A10i: a 15 inch box with more headroom and deeper low end, so full band worship and live music sound big and natural without pushing the system. Choose the array size and sub count that suits your room. Designed, supplied and installed by Forefront Productions.
Who it's for
Larger churches, worship auditoriums and performing arts centres from around 400 to 3000 seats. A15i Focus is a medium throw line source that projects up to 45 m, so it reaches the back of deep rooms, and wide rooms can take extra arrays. Seat count is a guide, and the shape of the room matters more.
Configurations
- 3x A15i per side, 2x KS21i: big, full range sound for services with a band, all running from one amp
- 3x A15i per side, 4x KS21i: more low end for contemporary worship, with a cardioid sub option
- 4x A15i per side, 2x KS21i: longer throw for deeper rooms
- 4x A15i per side, 4x KS21i: deeper rooms and a full band, with a cardioid sub option
- 5x A15i per side, 4x KS21i: our largest A15i system, for big, deep rooms, with a cardioid sub option and spare amp channels for front fills
Cardioid subs
With 4 KS21i grouped together, one sub can be turned to face backwards and run on its own amp channel. That cancels low end behind the subs, so the stage stays clean for the band and the worship leader while the congregation still gets the full weight. Every 4 sub configuration gives each KS21i its own amp channel to do it.
Amplification
Each configuration uses the most cost effective mix of L-Acoustics amplified controllers that still runs every speaker at full output, checked against L-Acoustics' published load limits. High power amps drive the arrays, and on the 4 sub configurations the subs get a dedicated 4 channel amp so cardioid is always possible.
What's included in every configuration
- A15i Focus line sources with an A15i Wide at the bottom of each array
- KS21i 21 inch subwoofers
- 1 x X8i coaxial centre fill for the front rows
- L-Acoustics amplified controllers sized to the configuration
- All rigging plates, plus an A15i Bump flying frame per side
- VBAR and TILT for ceiling mounting the centre fill
- Speaker cable with Neutrik speakON and XLR connectors
Forefront Tip
We model every room in Soundvision before we lock in a configuration, so you get the box count that actually covers your seats, not a guess. If your room is under about 1500 seats and the program is mostly spoken word, ask us about our A10i systems as well. Every venue is different, so contact us for a quote and a system design to suit your room.
