H-1 and H-2 Speakers
with 900MK2 EQ Modules
he H Series Interior Design
Speakers are the latest example
of TOA’s modern, innovative
approach to commercial speaker
design.The unique, stylish appearance and
superb sound quality of the three new
models, the H-1, H-2 and H-2WP, provide a
welcome alternative to conventional wall-
and ceiling-mount speakers.
Applications include speaker systems
for houses of worship, hotels, offices,
museums, restaurants, retail stores,
residential spaces and many others.The
H-2WP is a weather-proof version of the
H-2 for outdoor wall-mount applications
such as terraces, gardens, patios and
swimming pools.
The H Series Minimum Reflection
design significantly reduces sound wave
reflections and the resulting sound col-
oration that occurs with conventional
bracket-mounted "box" type speakers.
Wall- or ceiling-mount installation is fast
and easy using standard electrical gang-
boxes, and you can rotate and aim the
loudspeaker components without altering
the enclosure’s external appearance.
Each H Series speaker has a paintable
grille and features a high quality Ferrofluid-
cooled dome tweeter,Neodymium woofer,
70.7/100 V matching transformer and
removable terminal block.
900MK2 Processor Modules are also
available for convenient system equalization
using the industry-standard TOA 900MK2
Series Mixer/Amplifiers.

FEATURES
Sleek, Stylish Appearance blends well
with modern architecture for background/
foreground music and paging systems.
Wide Variety of Applications including
wall- or ceiling-mount speaker systems for
houses of worship, hotels, museums,
offices, restaurants, retail stores and resi-
dential spaces.
Weather-Proof Version Available, Model
H-2WP, for outdoor applications such as
terraces, gardens, patios and swimming
pools.
Minimum Reflection Design reduces
sound wave reflections typical of conven-
tional bracket-mounted “box” type
speakers.
Loudspeaker Components Rotate to
allow flexible aiming without altering the
enclosure's external appearance
(H-1: ±45o, H-2: 360o, H-2WP: ±45o).
Two-Way, Sealed Enclosure with High-
Quality Components:
•1" balanced-dome tweeter, Ferrofluid-
cooled
•3" x 2" cone woofer (H-1) or 4" cone
woofer (H-2/H-2WP) with Neodymium
magnets for improved low frequency
response.
Built-In 70.7/100 V Matching
Transformer (12 W max.) for distributed
speaker systems.
Protection Circuit to prevent loudspeaker
damage from excessive input.
Built-In Passive Crossover with opti-
mized filter slopes.
High Power Handling: 90 W for the H-1
and 120 W for the H-2/H-2WP
(Continuous Program).
Fast and Easy Installation:
•Using supplied brackets.
•H-1 Also Mounts Directly to Drywall
with supplied bracket (also available
separately, model HY-H1).
Push-On Grilles with Paintable Finish
allow custom-matching to any environ-
ment.

AWG #14 wire with loop-through termina-
tions for distributed speaker systems.
Convenient System Equalization with
900MK2 Series Modules, E-04R (H-1)
and E-05R (H-2/H-2WP). Equalization
parameters for DACsys II or similar digital
signal processors also available.

The H Series "Minimum Reflection" Advantage
H-1
The measured data below graphically illustrates the significant frequency response degradation
in the lower mid-range when mounting a speaker 5-20 cm (2-8 ") from a surface (typical with
bracket-mounted speakers). Surface reflections combine out-of-phase with the direct sound
H-2/H-2WP
and cause cancellations.The H Series semi-flush mounting (0 cm diagrams) minimizes the out-
of-phase reflections by eliminating the distance between the enclosure and the mounting sur-
face. See Frequency Response plots for H Series direct,reflected and summed response.
