Bogen S4 S4W 사용자 설명서

•  High sensitivity and exceptional power handling

•  Two models: S4 for 8 ohms; S4T for 70V & 8 ohms

•  75W at 8 ohms (S4 & S4T)

•  70V Power settings: 16, 8, 4, 2, 1 watts (S4T Only)

•  Hemispherical mounting system makes it simple to

mount, aim, and lock-in position of loudspeaker

•  4-1/2” metal-alloy MDT

TM

mid/bass speaker cone is

extremely stable in all environments

• Patented 

MLS

TM

Ferrofluid voice coil centering replaces

distortion-causing mechanical spider and seals
magnet gap

•  1” titanium high frequency driver delivers clear, articulate

response and consistent long-term performance

•  Wide, even coverage over listening area

•  High-density, injection-molded cabinet provides an

exceptional cosmetic finish

•  Low-resonance cabinet structure

•  Precisely designed low-frequency tuning for proper

balance

•  Advanced polymer compound cone surrounds resist

UV rays, chemicals, and salt spray

•  Aluminum-alloy & Titanium cones, UV-protected ABS

cabinets, and powder-coated aluminum grilles and
mounting brackets assure long-term cosmetic
and sonic durability

•  Pressure clamping input terminals for quick installation

The S4 & S4T compact, versatile speakers feature NEARʼs unique
driver technologies to produce the highest sound quality in the most
durable and reliable loudspeakers available. Precise sound repro-
duction is achieved with mid/bass drivers employing NEARʼs MDT

TM

and patented MLS

TM

technologies for superior sound and long-term

durability. The high-frequency driver is a 1” titanium diaphragm
which perfectly complements the metal-alloy LF driver. A built-in
16W transformer (S4T) makes it compatible with 70V sound
systems. The S4T speaker can switch between 70V or low-imped-
ance systems by using a power tap selection switch. NEARʼs
patented spiderless technology (MLS

TM

) and advanced materials

deliver out-of-the-box performance year after year. 

• High rigidity and low mass of metal versus traditional papers

and plastics (extremely stable cone structure over long
periods of time)

• Fast transmission of sound through the diaphragm means

low energy storage

• Special anodizing process creates a ceramic coating for

increased stiffness

• Efficient heat-sinking of voice coils under long-term,

high-power situations

•

Speaker diaphragms are manufactured with materials that
will not be altered by constant exposure to UV rays or water,
cold or heat, or extremely high or low humidity

•   Voice coil is constantly centered for lower distortion

•   Voice coil is more efficiently heat-sinked by fluid instead of air

•   Greater linearity is accomplished because the mechanical

spider is eliminated

•   Constant lubrication of the gap prevents oxidation from

humid environments
