Atlantic Technology IWCB-727 THX Operating manual

Like a world-class athlete.
Everyone is impressed with our In-Wall Closed Box series.
These unique models have defined a new level of in-wall
speaker performance with their solid, sealed MDF enclosures,
their easy installability, and their incredible placement
flexibility.
Now, we’ve taken the IWCB’s to a new level, with the
IWCB-727. The 727 is like a world-class athlete with all the
right moves: fast, powerful, and adaptable to virtually any
situation.
In fact, the 727’s performance is so good, it’s the very first
speaker of any kind to earn THX’s new stringent Select2
certification.
The 727 retains all the great features and technology of the
IWCB-52, -525, and -626:
•SealedMDFenclosureoptimizesperformance,removes
acoustic variability of wall cavity
•Atlantic-exclusiveLowResonanceTweeter(LRT™)handles
greater portion of sonic spectrum for wider dispersion
throughout listening area
•Atlantic-exclusiveDirectionalVectorControl(DVC™)
electronically directs sound up or down without the
mechanical or acoustic compromises of a “pivoting”
tweeter assembly

•SoundoptimizationcontrolsforHFlevel,boundary

But the IWCB-727’s performance goes beyond that of the
others in our Closed-Box line. It uses two sophisticated 6 ½”
carbon-fiber woofers in a 2 ½-way configuration, for maximum
output, sensitivity, power-handling, and optimum midrange
dispersion characteristics, as well as a brand-new
versionofourfamous1”LRT,forevenbetter
top-octave extension and greater HF
power radiation.

The systems are uniquely easy to mount, since their GFR grille/frame assemblies are sold separately. This means the
installer can run the wire to the speaker locations, then mount and paint the grille/frames to match the room. The
speaker assemblies can be installed at a later time if desired, optimizing the timing of the project.
For ease of installation
and total flexibility/
convenience, the
IWCB-727 uses the
same grill/frame
assembly and New
Construction Bracket
as the IWCB-626 (the
GFR-626 and
IN-NC-626).
