1.5AM

The Clair Brothers 1.5AM is a high output 15”coaxial stage monitor with incredible low frequencyoutput. This portable, low profile, high outputstage monitoring speaker delivers incredible SPL,exceptional vocal reproduction, and unprecedentedlow 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 productcan duplicate its combinationof performance, sizeand packaging.

The component at the heart of the 1.5AM is acustom coaxial assembly with the most powerfulcombination of woofer and compression driver onthe market in this size class. The high frequencycompression driver features a 2” throat diameter(4” voice coil diameter), a pure titanium 4”diaphragm with a titanium nitride coating and aneodymium magnet assembly. The driver is joinedto a 40° horizontal by 60° vertical rotatable horn.A 15” carbon fiber reinforced cone transducerprovides mid-bass and low frequency reproduction.The combination of our professional high-outputcomponents delivers exceptional performance.

Dual rear mounted EP-4 connectors (male andfemale) allow the use of multiple cabinets froma single amplifier. Low profile styling and flushmounted side handles provides great aestheticappeal and portability. The speaker grille isconstructed of aerospace grade 1/8” gaugeperforated aluminum and is specially treated tocreate a durable exterior finish.
Clair Brothers combines amplification, andproprietaryDSP processing in portable racks for allmonitor systems.Custom cabling for systems isavailable and can be pre-wired, labeled and deliveredin road cases.
As with all Clair Brothers products, the cabinet isconstructed of the finest Baltic birch and finishedwith a rugged polyurea paint to withstand the mostdemanding conditions.
