FR253HR Technical Specifications
APPLICATIONS
The FR253HR combines massive output
capabilities with the high fidelity accuracy
that only true three way loudspeaker
design can provide. Optimized for
portability and excellent coverage with
high output and extended bass response
in short to medium-throw applications,
the FR253HR would be at home in any of
the following venues and applications:
• Performing Arts Facilities • Theaters
• Corporate A/V
• Churches
• Touring Sound
• Clubs
• Professional Musicians
• Lecture Halls
• Portable Dance Systems
• Sidefill or Drum Monitor

ARCHITECTURAL SPECIFICATIONS
The loudspeaker system shall be a three-way design, incorporating two
15-inch low frequency cone-type transducer in a vented enclosure, two
170 mm (nominal 7-inch) poly-laminated cone mid frequency trans-
ducers, and a compression driver mounted on a constant horizontal
coverage high frequency horn. The mid frequency drivers shall be re-
cessed into the baffle for phase optimization and be mounted into sealed
sub-chambers within the enclosure.
The system shall meet the following performance criteria: Frequency
Response: 45 Hz to 17 kHz
±
3 dB. Axial Sensitivity: 102 dB SPL 1W@1m
over the 100 to 10 kHz band. Power Handling: 500 Watts full range
AES Standard. Vertical Coverage Angle: 50 degrees between -6 dB points.
Horizontal Coverage Angle: 100 degrees between -6 dB points.
The system shall include an internal passive crossover network, provid-
ing for both bi-amplified (with passive MF/HF crossover) or full range
passive operation via rear panel switching. The network shall be of a
third order asymmetrical design with compensation for maximally flat
response throughout the crossover region. Input connectors shall in-
clude dual 1/4” phone jacks, banana test points and Neutrik NL4
Speakon connectors located on the rear of the cabinet.
The cabinet shall be constructed of 18mm thick, void-free birch ply-
wood with a minimum of 18 plys to the inch and coated with a cata-
lyzed black polyurethane finish. The system shall be provided with re-
cessed handles on each side and two castors mounted on a cut-away
section of the bottom rear of the enclosure. All drivers and horns shall
be protected by a vinyl coated perforated steel grill.
The loudspeaker system shall be the EAW FR253HR.
