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.
Shipping: Shipping for this large item will be quoted and is not included in the price.
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.
System design for your venue
Every L-Acoustics system we supply starts with a system design. Before anything is ordered, we confirm the package you have selected is the right fit for your auditorium or venue. If a different array size, sub count or fill will serve your room better, we will tell you and show you why.
- Brief: we work through your room, seating layout, program and goals, plus any limits on rigging points, sightlines and budget
- Soundvision modelling: we build a 3D model of your venue in L-Acoustics Soundvision and predict coverage, level and tonal balance across every seat
- Configuration and rigging: array size, splay angles, trim height, sub placement and fills are all set from the model, not guessed
- System design report: you receive the recommended system, its predicted performance and the mechanical details we install to
The package you select is our starting point. We confirm the final configuration and your quote with you once the design is complete.
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
If your room is under about 1500 seats and the program is mostly spoken word, ask us about our A10i systems as well. Send a floor plan, the room dimensions and a few photos with your enquiry. It speeds up the system design and gets you an accurate quote sooner.
