Top 3 Fixed‑Installation Products from L‑Acoustics for Cultural Venues

A15i Focus

Application & Use Case: Medium‑throw deployments in theaters and auditoriums. Ideal where stage visuals and aesthetics matter, and where the venue wants both high acoustic output and reasonable size/weight.

Technical Highlights:

• Max SPL up to 144 dB (peak, in free field)
• Bandwidth: ~41 Hz–20 kHz (-10 dB)
• Directivity options via Panflex and L‑Vents technology: horizontal directivity selectable (70° / 90° / 110°), vertical ~10°
• Rigging / Installation features: Flush‑fitting two‑point rigging, handles and corner stops; weight ~35 kg; robust plywood cabinet; optionally IP55 finish

K3i

Application & Use Case: Long‑throw fixed installations — large halls or proscenium stages, venues needing strong projection, high SPL and ability to cover wide audience distances.

Technical Highlights:

• Active two‑way line‑source enclosure (installation version) with WST waveguide and Panflex control
• Maximum SPL ~143 dB peak.
• Bandwidth: ~42 Hz–20 kHz (‑10 dB)
• Very versatile directivity: horizontal directivities including symmetric and asymmetric patterns (70° / 110° etc.), vertical curvature adjusted via array geometry
• Installation features: external rigging kits; inter‑enclosure angles selectable (0.25° to 10°); rugged plywood enclosures, steel grills; finish options etc

KS21i

Application & Use Case: Low‑frequency reinforcement in fixed installations — subwoofers for halls, theaters, auditoriums. To provide impactful bass, required for orchestral, cinematic, or musical performance with punch and body.

Technical Highlights:

• 21‑inch driver, omni / cardioid subwoofer design.
• High power‑to‑size ratio: delivers substantial LF output while maintaining manageable footprint.
• Integration with L‑Acoustics electronics / controllers for alignment, delay, time‑coherent performance. Usable in flown or ground stacks

Why These Matter

These three models together cover a wide range of needs: from mid/long‑throw clarity (A15i Focus, K3i) to powerful, clean low‑end (KS21i).
All are part of the fixed‑install portfolio: designed with features like rigging, enclosures, weather / finish options, consistent dispersion control.
They integrate with L‑Acoustics tools — Soundvision for design/simulation, electronic controllers for delays and networked performance — allowing venues and integrators to model performance beforehand and tune precisely.

If you are specifying a sound system for a cultural venue, these loudspeakers are excellent starting points. Contact us for system design help, measurements, and recommendations that match your venue’s size, usage, and acoustic profile.
