The Clair Brothers 1.5AM is a high output 15”
coaxial stage monitor with incredible low frequency
output. This portable, low profile, high output
stage monitoring speaker delivers incredible SPL,
exceptional vocal reproduction, and unprecedented
low frequency reproduction from a small enclosure.
Designed for bi-amplification and custom processing
(utilizing Clair Brothers amplification and processing),
the 1.5AM is in a class by itself. No other product
can duplicate its combination of performance, size
and packaging.
The component at the heart of the 1.5AM is a
custom coaxial assembly with the most powerful
combination of woofer and compression driver on
the market in this size class. The high frequency
compression driver features a 2” throat diameter
(4” voice coil diameter), a pure titanium 4”
diaphragm with a titanium nitride coating and a
neodymium magnet assembly. The driver is joined
to a 40° horizontal by 60° vertical rotatable horn.
A 15” carbon fiber reinforced cone transducer
provides mid-bass and low frequency reproduction.
The combination of our professional high-output
components delivers exceptional performance.

Dual rear mounted EP-4 connectors (male and female) allow the use of multiple cabinets from
a single amplifier. Low profile styling and flush
mounted side handles provides great aesthetic
appeal and portability. The speaker grille is
constructed of aerospace grade 1/8” gauge
perforated aluminum and is specially treated to
create a durable exterior finish.
Clair Brothers combines amplification, and
proprietary DSP processing in portable racks for all
monitor systems. Custom cabling for systems is
available and can be pre-wired, labeled and delivered
in road cases.
As with all Clair Brothers products, the cabinet is
constructed of the finest Baltic birch and finished
with a rugged polyurea paint to withstand the most
demanding conditions.
