ELECTRICAL SPECIFICATIONS
Power rating: 100W RMS (RS426B test procedure)
Frequency response: 97Hz-20kHz + 6dB
Sensitivity: Log average 87.8dB
Woofer: 6.5" mica coated with rubber surround
Impedance: 8 ohms
Speaker Mounting:
The OS100TW (white) and OS100TB (black) speakers may be mounted
indoors or outdoors (when protected from direct moisture). The included
aluminum U-bracket has mounting slots that line up with a properly secured
metal single gang outlet box, whether mounted vertically as shown in Figure 1,
or horizontally as shown in Figure 2. If more flexible aiming is required,
OS100T speakers may also be mounted using the optional Lowell OS-BRKT
brackets (See Figure 6) or Omnimount 20.5 Series brackets (See Figure 7).
(Purchase directly from Omnimount). Three (3) 1/4-20 threaded insert points
are provided on the rear of the OS100T speakers for these brackets (See
Figure 3). A speaker transformer select switch is provided on the rear of the
OS100T speakers (See Figure 3). With this switch in the 8 ohm position, the
transformer is disconnected internally and the speaker power rating is 100W.
With this switch in the A-D positions, the speaker power is determined by the
driving voltage as shown on the table on the rear of the OS100T speakers and
as shown on the table below. Incoming wiring should enter through the
weather-resistant terminal cover (See Figure 8). The rubber grommet may be
removed to accommodate larger wiring. Be sure to push the terminal cover on
until it snaps to assure a tight seal. Wiring is to be connected to the 4-
conductor removable phoenix type connector (See Figure 4 and Figure 5).
Parallel dual "+" and "-" terminals are provided in order to terminate incoming
and outgoing wiring. Lowell Manufacturing Company recommends that a
safety cable always be used when speakers are installed over-head. It is the
responsibility of the installer to consult a Licensed Structural Engineer to verify
the structural integrity and safety of any mounting method before installation.
