EAW FR102 User manual

Ultra Compact Size Occupying less than one cubic foot of volume, the FRI02 is the ideal problem
solver for tight fitting applications such as under balcony fill, foreground
music, satellite W/HF and highly portable AV presentations.
Exceptionally Wide The FRI02 maintains a horizontal coverage of 110 degrees above 16,000 Hz
Horizontal Coverage so even the highest musical overtones can be heard by every listener. This
wide open sound contributes to the FRI02's natural "hi-fi" sound character.
High Output Capabilities The combination of the FRI02's 98 dB SPL sensitivity and 250 watts of AES
standard power handling results in 121 dB SPL maximum output at one meter.
This enables the FRI 02 to offer the equivalent output of 4 to 8 typical hi-fi or
compact studio monitor loudspeaker systems.
Ultra Durability The FR102, despite its size, is built to the same standards of contruction as
EAW's concert sound reproducers and, as such, provides a level of durability
and reliability virtually unmatched in the pro sound industry. All exterior
surfaces are constructed of imported multi-ply cross-grain-laminated birch
hardwood. Standard features include perforated steel grills, recessed hand
holds and catalyzed polyurethane coating finish.

Wide Coverage
Compact Full
Range System
Design Leadership The FR122 is the direct descendant of EAW's FRIOO, the industry's original
compact system with a dome driver. While the rest of the industry has been
busy playing catch-up, EAW again leads the way with our third generation
design. The FRI 22 incorporates the latest design developments, including time
compensation, magnetic damping fluid and bi-frequency vent design. These
advanced features enable the FRI 22 to offer performance simply unequaled by
any other system near its size. Listening to the FR122, you will be aware that
each and every aspect of the FR122 reflects EAW's advanced engineering
capabilities and dedication to accuracy. This master craftmanship is inherent in
EAW's philosophy and is what makes our products unique in comparison to
the mass produced products offered as competition.
Coherent Time Design The FRI 22 utilizes a -time offset baffle designed to ensure proper driver time
alignment at crossover for maximal smooth crossover response.
Compact Durable The FR I22's small (1.6 cubic foot) size enables two units to fit in the back seat
Package of most commuter cars. The small size also makes installation quick and easy.
Unique RCF Hard Dome RCF's TW 116 hard dome high frequency driver is the key to the FRI 22's
High Frequency Driver exceptionally natural sound character. This 52 mm (2 in) dome design is
similar to the drivers found in the finest hi-fi systems, but its massive magnetic
structure produces output levels required for professional use. The result is 6
to 10 dB higher efficiency and 3 to 6 dB more power handling than home hi-fi
systems, but the TWI 16 retains the smooth response, low distortion and wide
coverage of the dome design. No other pro system with a horn tweeter can
match the FRI 22's natural open sound and excellent imaging.
Space Age Magnetic To further enhance the performance of the TW 116, the FRI 22 makes use of
Damping Fluid "space age" magnetic damping fluid in the voice coil gap. Conventional drivers
have air in the voice coil gap which acts to thermally insulate the voice coil from
the magnetic assembly. By filling the gap with magnetic fluid, heat build up in
the voice coil is drawn into the magnet assembly, where it can be easily
dissipated over the large surface area of the entire driver. The result is a 3 to 6
dB, increase in long term power handling, virtually eliminating thermal failures.

Low Frequency Section
The 300 mm (12 in ) high pressure die cast bass driver is
loaded into a 45 liter vented box incorporating EAW's
exclusive bi-frequency tuning system. This technique makes
use of two vents tuned to different frequencies, lowering the
low frequency limit of the system. This is accomplished
without response ripples normally associated with super low
tunings. The result is strong response down to 50 Hz,
without external equalization. The bi-frequency tuning
system also reduces driver excursion at low frequencies and
distortion, resulting in greater bass definition and more
realism in the sound.
Crossover Design & Construction
The crossover network is the heart of any system and the
FR122's crossover is the most sophisticated available in any
compact pro system. Crossover development at EAW is a
long and painstaking process. Parameters are mathematically
calculated and continuously adjusted during extensive
listening and precision acoustic measurement evaluations.
The final design is then built into a run of systems, each one
tested for variations. The design is then modified to
compensate for these variations. At each step in this process,
the filters are optimized to provide maximal electrical
damping and minimum phase response while providing a
smooth transition between drivers. The resulting crossover is
a third order design with nonsymmetrical slopes for
crossover equalization.
To guarantee that production crossovers achieve their design
specifications, we individually test each crossover
component and the final product to be within 3% of the
original design values. This intensive effort results in the
elimination of crossover induced distortion, typically the
highest source of distortion in compact systems.

Wide Bandwidth
Nearfield Full
Range System
Exceptionally Wide The FR153's usable frequency range of 30 Hz to 22,000 Hz enables it to
Bandwidth accurately reproduce the full musical spectrum from deep fundamentals to the
most delicate overtones. This enables your audio presentation to take full
advantage of modem electronically synthesized music with hi-fi realism.
Unmatched Wide Horizontal coverage of the FR 153 is greater than 130 degrees up to 10,000 Hz
Horizontal Coverage and 100 degrees coverage is maintained above 16,000 Hz. No other high
output system can match this ability to provide excellent sound over as broad a
listening area. The natural wide open sound is the result of RCF's unique
TW1 16 hard dome high frequency driver.
State Of The Art Drivers Using the latest developments in driver design permits the FRI 53 to reach new levels o
f
sonic definition for a high output system. The RCF TW 116 hard
dome driver is a truly unique device incorporating advanced magnetic circuit
,design and space age magnetic fluid for voice coil cooling and damping. EAW's
advanced
MF170A 7-inch mid range driver utilizes a poly-laminated cone to reduce
distortion, while its small piston size has been optimized for flat power response. The
RCF PRO L 15/542 bass driver was computer optimized for ideal vented box
performance, enabling lower distortion over its pass band.
Advanced Crossover Kenton Forsythe's advanced crossover is the key to the FR153's seamless
Network frequency response. The complex third order network utilizes asymmetrical
electrical slopes to provide equalization at the crossover points resulting in
maximal flat acoustic performance with effective 24 dB per octave acoustic
slopes. The crossover also features electronic damping for the system, high
frequency level control and driver protection fuses. Crossover construction sets
the standards for quality in the audio industry: all components and assemblies
are 100% tested. The crossover itself will handle 400 watts thermally for 24
hours and pass 1500 watts for 10 minutes without distortion.
