Snell IW-J7 User manual

IN-WALL VERSION OF OUR J7, PERFECT FOR MUSIC AND HOME THEATER
The IW-J7 is Snell’s J7 monitor, re-engineered for flush-mount use. As you
would expect, many of the features developed by Snell over the past 30 years,
are in full use. To achieve the performance capabilities of a freestanding
monitor, this new design overcomes the three factors limiting all in-wall
speakers. First, to insure predictable response, regardless of placement or
wall type, the IW-J7 has been designed with an integrated and sealed,
aluminum enclosure, which, like all conventional loudspeakers, determines
the speaker’s bass response. Second, superior materials are used in the
IW-J7 to control resonance. Where other in-walls are open-backed and made
of plastic, we mount our J7 drivers to a specially damped MDF baffle,
constructed in three layers to enhance bass/midrange clarity and deaden wall
resonance. The baffle secures to a well-damped, heavy gauge aluminum
enclosure. Third, most flush mount speakers cannot reproduce a
proper soundstage. To assure the spatial realism found only in
high-performance monitors, the IW-J7’s low-resonance, silk dome tweeter
has incredible dispersion, well into the voice range. For enhanced
performance a new crossover was designed to “tune” the IW-J7 to its in-wall
boundary, and uniquely extend bass in a small volume cabinet.
The precision crossover is hand tuned to guarantee performance to within a
remarkable 0.5dB of the Reference Master.
