User Manual

Technical
Specifications
The loudspeaker shall be NEAR Model S5 or S5T with
a power handling capacity of 150 watts @ 8 ohms, or
32W @ 70V input (S5T), or approved equivalent. The
loudspeaker shall consist of one 5-1/4 inch metal-alloy
low-frequency diaphragm transducer and one horn-
loaded 1-inch titanium high-frequency diaphragm
transducer. A crossover network provides dividing and
smoothing of frequencies between the transducers.
A mathematically-aligned and vented molded enclosure
shall house all components. High-density ABS cabinet
material and powder-coated aluminum grille material will
assure long-term cosmetic stability.
The high-frequency driver shall utilize a rigid titanium
diaphragm and integral compounded rubber surround
for proper damping and long-term reliability.
The low-frequency driver shall utilize a metal-alloy
diaphragm with deep-anodized surface treatment for
rigidity and corrosion resistance. The cone shall provide
a heat transfer thermal path for the voice coil under
high-power inputs. Compounded rubber cone surrounds
shall be formulated to provide a high degree of damping
and long-term performance without decay.
The voice coil will be centered via a high gauss, low
viscosity magnetic fluid (Ferrofluid), which increases
the heat transfer efficiency from the voice coil to the
speakerʼs mechanical structure under long-term high-
power use. The magnetic fluid shall provide corrosion
resistance in the magnet gap.
The mounting bracket provided with the speaker shall
be designed to provide angular movement horizontally
and vertically to facilitate proper directional coverage. It
shall allow both vertical and horizontal orientation of the
loudspeaker. The bracket shall be formed from cast
metal-alloys with a scratch-resistant, powder-coated
finish. The input connectors for 8-ohm and 70V systems
shall be via a positive pressure-clamping device to facil-
itate connection of the speaker input wires.
Dimensions of the speaker shall not exceed 6-7/8” W x
9-3/4” H x 6-1/8” D without the bracket attached;
or, 6-7/8” W x 9-3/4” H x 8-1/8” D with the bracket
attached. Weight shall not exceed 8 lbs. for the S5,
or 9 lbs. for the S5T.
