introduction

Congratulations, and thank you for purchasing an a/d/s/ Home Theatre in-wall speaker system. The HT­series offer the perfect combination of style and performance to meet the most exacting audio and
interior design standards. The proprietary driver design and computer-optimized crossover networks result
in a smooth, flat frequency response, which in turn yields exceptional imaging and superb transient
impact. The bass response and acoustic output capabilities of your HT series speakers are remarkable for
units of such compact dimension. a/d/s/ Home Theatre speakers are the ultimate match for your
discerning taste and lifestyle.

Be sure to save your sales receipt. It is your best record of the date of purchase, which is required for
warranty service.

Read and follow all cautions, warnings and notes.

cautions

To reduce the risk of electric shock, do not remove any parts of the speaker. There are no user serviceable
parts inside. If service is required have it performed by a qualified service professional.

WARNING

To prevent fire or shock hazard, do not expose the speakers to rain or submerge in water. The speakers
should be situated away from heat sources such as radiators, heat registers, stoves or other heat sources.

Be sure all the components in the system are turned off while making audio and power connections.

features

tweeter

The HT series incorporates the use of a 1” copolymer dome tweeter with a Ferrofluid™ damped voice coil.

tweeter protection

A solid state device reduces power to the tweeter when the loudspeaker is operated at unsafe power
levels. It resets automatically when power is reduced to a safe level. Note: the tweeter protector provides
a significant level of protection. However it does not guarantee that the tweeter cannot be damaged.
Always be careful when operating the speakers at a high volume level.

high frequency contour switch

A 3-position switch located on the tweeter plate serves as a high frequency contour control. The upper
position offers a “normal” response suitable for most applications. The bottom position provides the
most output and is recommended for off-axis listening or if the speakers are mounted very high. The
center position provides the least and is recommended for reflective “bright” rooms. The upper position
is the best starting point. Due to room acoustics and/or personal preference, you may prefer either of the
other positions. Be sure to try all of these positions and decide on your preference before installing the
grills. If you find it necessary to re-adjust the tweeter levels after the grills have been installed, please
follow the removing the grille section on page 6.

woofer

The HT series incorporates the use of a 5 1/4” woofer with a proprietary diaphragm made from a spherical
inverted dome sandwiches to a copolymer cone, and utilizing a strontium ferrite magnet structure for
well-damped, extended bass.

advanced industrial design

In the world of in-wall speakers, most competing products can be categorized by their incredible degree
of similarity. Regardless of the manufacturer, product offerings are limited to the same style of molded
plastic chassis, the same types of mounting systems, similar drivers and the same limited performance
capability. The HT series is a striking exception to this trend. Using the most advanced injection-molded
driver technology available, it outperforms all others in its category. Attractively styled in a neutral off­white finish, it can be painted to perfectly match any wall.

aluminum extrusion mounting side-rails

The advantage to this design is an incredibly rigid, durable mounting system that runs the entire length of the
speaker from top to bottom. The mounting brackets do the same. As a result, the speaker is tightened to the
wall over the full length of both of its sides.

quick & easy post-construction installation

Thanks to the aluminum extrusion mounting side-rails, installation couldn’t be easier. Cut out the hole, insert the
speaker, and tighten the screws. That’s all there is to it.

engineered for critical music listening

While it is believed by many that in-walls do not do the best job of reproducing audio, a/d/s/ pushed the envelope
in engineering this line of in-walls. From beginning to end, the HT series was engineered to deliver the best
possible sonic reproduction.

d’Appolito array (HT400iw & HT800iw only)

The d’Appolito array offers symmetrical and uniform dispersion making it possible for horizontal or vertical
installation adding appeal for the home-theatre enthusiast.

“2 1/2-way” crossover (HT800iw only)

The crossover was designed using all high quality components to create smooth acoustic slopes, while the “2
1/2-way tuning” helps to add crisp, clean bass. The two center woofers and tweeter perform exactly as the
HT400iw creating a complete 2-way system. The two outside drivers are responsible only for the reproduction
of low frequencies helping to augment the bass output.
