Unique appearance blends well with modern architecture
for background/ foreground music and paging systems.
Two-way, sealed enclosure with high-quality components:
2.5 cm dome tweeter and dual 10 cm woofers both
equipped with neodymium magnets.
Wide Variety of Applications including hotels, houses of
worship, museums, offices, residential spaces, restaurants,
and retail stores.
Built-in 70/100 V matching transformer (30 W max.) for
distributed speaker systems.
Wide coverage area: 140° horizontal x 70° vertical
dispersion.
Protection circuit prevents loudspeaker damage from
excessive input.
Weather-resistant version available, model H-3WP, for
outdoor applications such as gardens, patios and swimming
pools.
Built-in crossover with optimized filter slopes.
UL-listed fire-resistant material.
Minimum reflection design reduces sound wave reflections
typical of conventional bracket-mounted "box" type
speakers.
High power handling: 150 W (Continuous Program)
Removable terminal block with loop-through terminations
for distributed speaker systems to custom-match to the
environment.
Paintable grille to custom-match to the environment.
THE H-3 TWO-WAY WALL-MOUNT SPEAKER featuring
wide horizontal dispersion. The H-3's unique appearance and
superb sound quality provide a welcome alternative to
conventional wall-mount speakers for spaces where
appearance is a prime consideration.
Applications include speaker systems for hotels, houses of
worship, offices, museums, residential spaces, restaurants,
retail stores, and many others. A weather-resistant version,
model H-3WP, is also available for outdoor applications such
as gardens, patios and swimming pools.
The H-3's wide 140 degree horizontal coverage pattern
provides a solution for eliminating deadspots inherent
between wall-mounted speakers. Also, the Minimum
Reflection design significantly reduces sound wave reflections
and the resulting sound coloration that occurs with
conventional bracket-mounted "box" type speakers.
The H-3 is a two-way, sealed enclosure with high quality
components including a 2.5 cm dome tweeter, dual 10 cm
woofers, matching transformer, and removable terminal block.
The grille is paintable for custom-matching to the room decor.
