Overview

The ARC series brings the essence of Luno engineering to architecture itself — discreet, durable, and effortlessly clear.
Behind its clean form lies a precision two-way system tuned for warmth and detail, capable of filling spaces evenly without overpowering them.
Designed for homes, hotels, and commercial installations where design and sound must coexist.

Highlights

  • Balanced clarity from a 4″ / 5″ / 6.5″ woofer paired with a 1″ tweeter
  • Versatile connectivity — 8 Ω or 70 V / 100 V constant-voltage options
  • Consistent performance at 20 W – 40 W rated power, 40 W – 80 W max
  • Wide dispersion (89–90 dB sensitivity) for even coverage across rooms
  • Weather-resistant design (IP55) suitable for indoor and covered outdoor use
  • Sleek ABS enclosure available in matte black or white
“True sound doesn’t need to stand out to be heard.”

Design & Engineering

Every detail of ARC serves one purpose — effortless integration.
A lightweight ABS cabinet minimizes resonance, while the precision crossover ensures seamless transition between low and high frequencies.
Its compact dimensions (from 152 × 119 × 217 mm to 198 × 152 × 285 mm) make installation simple in any environment — from gallery walls to villa terraces.

Key design details:

  • Acoustic-neutral ABS housing with magnetic grille
  • Rotatable mounting bracket for flexible placement
  • Moisture-resistant components for long-term reliability
  • High-efficiency driver design to deliver clear output with minimal distortion

Performance You Can Feel

ARC delivers a natural sound signature with defined mids and extended highs (70 – 20 kHz frequency response).
Voices remain crisp, bass stays tight, and music feels full even at lower listening levels — ideal for background music, voice reinforcement, and ambient installations.
