Versatile configuration possibilities
Flexible speaker configurations can be combined to achieve
a precision sound array with optimal response for both
sound coverage and dispersion over the targeted listening
area, near and distant. The result is minimal sound level
differences whether the listener is close or distant from
speakers.
Suits difficult environments
Type S Series speaker enclosures are designed to minimize
floor- and ceiling reflections to maximize sound clarity in
problematic environments that are reverberant.
High resistance to feedback
Because output levels do not become excessively high right
close to the speakers, they are able to resist feedback to a
high degree. Gain levels for a system are therefore easier to
set.
Single or biamp operation
Type S Series speakers can be driven with a single amplifer
or biamped as required (simple internal wiring change). For
improved performance an external DSP can be used to set
crossover frequencies and slopes.
Multiple speaker connectivity
Using optional TOA MT-SO601 matching transformers
allows use in high impedance applications.
Heavy-duty use
Type S Series speakers are designed to satisfy the rigorous
demands of permanent installations that are used
extensively.
TOA Type S Series Line Array Speakers provide optimal
coverage and dispersion characteristics. Available in slim,
tower-configured enclosures, these speakers also feature a
wide range of mounting accessories to enable permanent
installation in various venues.
The SR-S4L and SR-S4S speakers are 2-way line array
speakers that are vertically configured. Each configuration
contains 32 speaker elements composed of eight 10cm
woofers and 24 high frequency drivers which are positioned
close together to create a continuous linear sound source. The
speaker output therefore maintains a uniform sound pressure
level that resists attenuation with distance. The SR-S4L
speaker features a linear design tailored for distance sound
transmission applications and the SR-S4S features a gently
curved line designed for a 10°vertical coverage area which
offers ideal sound coverage over a shorter distance.

Note:
1. Install the speaker with its air hole down, as
indicated by the Up mark on the speaker.
2. It features the water protection construction
(IPX4), however it is recommended that it be
installed under roofs, eaves, or other locations
not directly exposed to rain or snow.
3. For outdoor permanent installation, the
installation angle of the SR-S4LWP must be
between 0˚ horizontal and 45˚
(SR-S4SWP: 30°)
downward as shown at the above.
Do not install the speaker horizontally.
4. When permanently installing the speaker
outdoors, inspect it periodically.
