IMPORTANT NOTICE

All new speakers require a minimum of 60 hours break-in-time before
they sound the way they are supposed to. A speaker's performance improves significantly
once broken in. It is critical that you have at least 60 hours on your speakers before you
evaluate them. Don't worry if your speakers do not sound perfect the first time you play
them. This is normal until they are broken in. If you are having difficulty getting enough
hours on your speakers and your 30 day return privilege is getting near, call us. We will
work with you. Please give us the courtesy of breaking the speakers in before you
determine they don't sound right.

Many of our customers break their speakers in by:
A) Leaving them on at moderate listening levels when they are not home.

B) Leaving them on at moderate listening levels while they sleep.
C) Running pink noise through them.

These methods are not convenient for everyone and we understand this. But please
know that you are not giving yourself, your speakers or us a fair chance if you do not break
them in before critical evaluation.

THANK YOU!

The XLC

Thank you for your order and congratulations on becoming the owner of an Audio Concepts, Inc. (ACI)
speaker system. The XLC is an audiophile quality system that will provide you with many years of listening
pleasure. Be sure and take a moment to register your warranty either by mail or on-line at www.audioc.com.

Derived from our acclaimed Essence and Sapphire XL, the XLC has all the qualities you expect from
an ACI center:

• Precise tonal matching with other ACI models

• Dynamic capabilities that will handle the most intense soundtracks with ease

• Dialog reproduction second to none

• ACI build quality and beauty

Only a center with a vertical mid-tweeter alignment with flanking woofers can provide this kind of
performance. Only a center with drivers this good need apply for the job. Only a center with ACI designed
precision crossovers will fit this bill. And, only a center built by ACI will look and sound this good!

As in all ACI products, the finest drivers are used with extensively engineered and tested precision
crossover networks. The cabinets are built to be extremely inert with extensive internal bracing. The midrange
chamber is specially shaped and damped. All design and quality aspects combine to yield absolute state-of­the-art sound. The use of the finest lacquers and select hardwood veneers results in a cabinet of exceptional
beauty and durability.

Design philosophy for the XLC

Modern speaker design is a combination of science, art and sweat. A successful design such as the
XLC requires thousands of hours utilizing computer modeling, several generations of prototypes, precision
testing, critical listening and many "fine tunings".

The XLC was designed as the perfect center for matching to the acclaimed Sapphire XL. The XLC
also had to be the ultimate performer not only for the center channel, but for all channels in a multi-channel
