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

•Atlantic-exclusiveLowResonanceTweeter(LRT™)handles

•Atlantic-exclusiveDirectionalVectorControl(DVC™)

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

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).
