Description

The SM890i is a premium high-SPL,
high-efficiency surface-mount loud­speaker for distributed or 8 ohm systems.
The SM890i incorporates a dedicated
8-inch treated fiber woofer and a high­power compression horn transducer with
a BroadBeamHP® waveguide to deliver a
consistent dispersion pattern and superb
intelligibility for the foreground music,
sound reinforcement and PA markets.

The SM890i uses a 150-watt low-inser­tion loss transformer and a six-position tap
switch with a transformer bypass position.
Mounting hardware includes SoundTube’s
proprietary tool-free, low profile Stealth™

High-Powered Surface-Mount Speaker

Preliminary Technical Information for System Engineers

bracket with an integrated internal
wedge cam, which allows for stable and
precise aiming from 0 to 90 degrees.

Corrosion-resistant materials, includ­ing powder-coated steel grille plus all­aluminum mounting hardware, make
the SM890i ideal for indoor/outdoor use.

Applications

Engineered for applications requiring
high SPL and maximum intelligibility,
the SM890i delivers a smooth and even
coverage pattern ideal for casinos, con­vention centers, gyms, nightclubs, aero­bic rooms, airports, super stores, arenas,
theme parks, transportation hubs, ship­ping centers and stadiums. For addi­tional low-frequency response down to
41 Hz (-10 dB) the powered SM1001-P
may be incorporated.

BroadBeamHP® Wide Disper­sion Technology

BroadBeamHP® technology delivers
a consistent dispersion pattern across
the upper registers of the frequency
spectrum and delivers maximum edge­to-edge coverage and intelligibility. For
the SM890i, SoundTube’s proprietary
BroadBeamHP® technology incorpo­rates a high-frequency compression
driver with a 1-inch exit and an 8-inch
treated fiber woofer. For installer conve­nience, the SM890i 110° x 85° compres­sion horn can be rotated 90 degrees to

tailor the speaker coverage to the venue.

Independent Data Acquisition and
Verification

All data for SoundTube speakers are
independently collected and verified
by NWAA Labs (www.nwaalabs.com)
using their proprietary MACH test­ing system. All data are collected and
analyzed according to ASTM, ISO and
AES standards using EASERA, TEF and
MLSSA. Full balloon data including
both phase and magnitude are compiled
into a variety of formats including EASE

4.x, GLL and CLF.

Architectural Specifications

The loudspeaker shall consist of one
203 mm (8.0 in.) low-frequency transducer
and one 36.0 mm (1.42 in.) compression
driver. The system shall include a crossover
network and a 150-watt low-insertion loss
transformer installed in the enclosure. The
low frequency voice coil diameter shall be
34 mm (1.34 in.).

Performance specifications for a typical
production unit shall be as follows: Useable
frequency response shall extend from 63
Hz – 22 kHz (-10 dB). Measured sensitivity
(2.83 volt, 1 meter) shall be at least 93 dB. The
speaker shall have a nominal impedance
of 8 ohms. The speaker shall be available
for 25-, 70.7- and 100-volt modes and shall
include a six-position tap switch with a
transformer bypass position. The frequency­dividing network shall have a crossover
frequency of 2.5 kHz with slopes of 12 dB
per octave (2nd order) for both low- and
high-pass filters. Rated power capacity shall
be at least 150 watts continuous (RMS) and
conform to EIA-426B testing. Maximum

continuous output at 1 meter shall be 115 dB.

The low-frequency transducer shall
have a treated fiber cone with treated cloth
surround. The high-frequency transducer
shall be an offset compression driver with
a proprietary 110° x 80° BroadBeamHP®
waveguide. The high-frequency transducer
shall be bayonet-mounted to allow the horn
to be rotated 90 degrees to tailor the cover­age pattern to the venue.

Installation for the speaker shall be by a
tool-free, low profile bracket with an inte­grated internal wedge cam for stable and
precise aiming from 0 to 90 degrees. Mount­ing hardware shall be constructed of die­cast aluminum.

The enclosure shall be constructed of
injection-molded ABS with glass fiber rein­forcement. The grille shall be powder-coated
steel with a tool-free locking system. Overall
dimensions including the mounting plate
and bracket for the SM890i are 477.0 mm
(18.78 in.) tall by 295.9 mm (11.65 in.) wide by

350.1 mm (13.78 in.) deep.

The system shall be the SM890i for both
low- and high-impedance applications.
