The OS-150TW (white and OS-150TB (black speakers may be mounted indoors ) )

or protected (covered outdoors The models are identical except for color In this ) . .

installation sheet the speaker will be referred to simply as the OS-150T The front , .

of the speaker (See Figure 1 is protected with an aluminum fine mesh grille with a )

weather resistant scrim material behind the grille. The speaker and grille may be

wiped down for cleaning but the use of a power washer or other high pressure ,

cleaning equipment will void the speaker’s warranty. The rear of the speaker (See

Figure 2 includes a U-bracket and an input selector switch. )

The OS-150T includes a heavy steel plated and powder coat painted

U-bracket that allows the OS-150T to be mounted vertically (See Figure 3 or )

horizontally (See Figure 4). Only install the OS150T in a protected (covered)

outdoor location and tilt the speaker slightly downward to prevent moisture

from collecting in the drivers. The U-bracket includes a 5/8 diameter center "

hole that may be used to route the speaker cable into the wall. The bracket

also includes vertical and horizontal mounting slots that make it possible to

secure the mounting bolts to the wall and then slide the bracket over those

bolts to hang the speaker (See Figure 5). Be sure to securely tighten the bolts

after the speaker is in place. Some installers prefer to remove the bracket and

mount it to the wall first. That makes it easy to lift the speaker and attach it to

the bracket by replacing the bracket knobs.

The two angle adjustment knobs may be removed and then refastened

through the optional mounting holes in the U-bracket to allow horizontal shelf

mounting with the maximum downward tilt angle of 40 degrees down from

horizontal (See Figure 6).

Speaker Mounting:

SAFETY NOTICE: Speaker installation should only be performed by experienced

qualified professionals with knowledge of the proper load-rated hardware and

safe mounting and rigging techniques. The speaker system must be mounted in

accordance with all local, state and federal codes and regulations and the ,

installation must conform to industry standard practices. It is the responsibility

of the installer to consult a licensed mechanical or structural engineer to

evaluate and certify the structural integrity and safety of any mounting method

before installation. Lowell Manufacturing is not responsible for the use misuse, ,

or misapplication of this loudspeaker product.

The optional U-bracket mounting holes can also be used to mount the speaker

in the vertical orientation (so the speaker can be adjusted horizontally to the

right or left but by attaching the top knob to the furthest hole from the rear of )

the bracket and by attaching the bottom knob to the closest hole in the bracket

(See Figure 7) an automatic degree downward tip of the speaker will result. , 4

A 4 degree upward tilt can also be achieved by attaching the top knob to the

closest hole from the rear of the bracket and by attaching the bottom knob to

the furthest hole in the bracket See Figure 8).

Lowell Manufacturing recommends that a safety cable be used when

speakers are installed over-head The OS-150T has four (4 -20 tapped . ) ¼”

insert points on the rear of the speaker. When mounting the speaker using

the U-bracket that is included, one or more of those ¼”-20 tapped insert

points can be used to attach a safety cable .

Due to its 70o square linear dispersion pattern (same vertical dispersion as the

horizontal dispersion) the OS-150T is ideal for use in open architecture ,

ceilings firing straight down in a distributed speaker system (See Figure ). 11

The maximum recommended center-to-center spacing is given in the table

below for edge- -edge spacing at a 4 average listening level. Note that to '

center-to-center spacing that is closer than the maximum given in the table,

will result in desirable overlapping coverage. Spacing that is farther apart than

the maximum given in the table will result in undesirable dead spots between ,

the speakers where the coverage is not optimized for listening. The paper at

the link below explains the “linear dispersion” concept for distributed systems.

A sound system should be able to achieve a minimum sound pressure level at

every listeners position of at least dB above the loudest expected ambient 10

noise level. To assist the designer with those calculations the on-axis ,

maximum sound pressure level for the OS-150T is given in the table below for

the selector switch in the 8-ohm position (150 watt input and for each of the )

possible transformer tap input selector switch positions.

Note Safety cable is not shown.:

For some OS-150T installations the installer may choose to use an omni-style ,

bracket (by others to mount the OS-150T instead of using the U-bracket that )

is included. When an omni-style bracket is used remove the two bracket ,

knobs discard the U-bracket and then replace the bracket knobs in the , ,

tapped holes. The OS-150T has four (4 -20 tapped insert points on the ) ¼”

rear of the speaker that are spaced to accept an Omnimount 25.0W bracket

(see Figure 9 or Adaptive Technologies Group MM-016-BT bracket (see )

figure ). 10 When another manufacturer’s omni-style bracket is used to mount

the OS-150T overhead one of the U-bracket knob 5/ "-18 insert points , 16

should be used to attach a safety cable.
