IMPORTANT NOTICE

All new speakers require a minimum of 60 hours break-in-time before they begin to
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:

3

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!

READ FIRST! QUICK SETUP

p

The flexibility of the Titan II LE allows it to be easily and quickly installed in virtually any
audio system. By reading the following steps and referring to the diagrams in the owner’s
manual, you’ll have your Titan II LE(s) up and running in no time.

1) Determine if you will need to use the Speaker Level Converters (two supplied). If your receiver,

pre-amp or processor (source) has RCA subwoofer output(s) or pre-out, main-in, you will NOT
use the Speaker Level Converters.

2) If you will be using the Speaker Level Converters, you will use both converters, connect as

shown in the Titan II LE hookup section diagrams for using a receiver. Connect the Speaker
Level Converters to the Titan II LE Inputs. Hook up your speaker cable from the same output
terminals you are using for your main speakers. Connect the speaker cable and the Speaker
Level Converters. Connect the same polarity as your main speakers, red to red, black to black.
Skip the following step and continue to Turn-On.

3) If you are using direct RCA connections, you may have several hook-up options. Try the simplest

first. If your source has subwoofer outputs try that first. Use a shielded RCA cable of sufficient
length to connect the subwoofer output of your receiver/processor directly to the Theater input on
the Titan II LE. Turn both crossover controls to 250Hz.
If you don’t have sub outputs you will use the pre-outs as shown in the Titan II LE hookup
section page 13 or 14. If you only have one set of pre-outs you will need to use a Y Adapter and
RCA interconnect or jumper to connect to the main amp inputs.
If you are using the optional Passive High-Pass Filters they insert into the main amp inputs (see
below).

Turn-On

4

-Turn volume control (Input Level) on the Titan II LE(s) all the way down set both crossover
controls (Lowpass Filters A & B) to about 100Hz, (250Hz if using Theater input).

-Turn volume control on source all the way down.

-Plug in and switch on the Titan II LE(s). There will be a slight thump, this is normal.

-Play some music with a consistent, clear bass line at a moderate level.

-Turn the Titan II LE volume level up slowly until it just fills in the bottom range.

-NOW, sit back and relax with some good music while reading the manual which will help you
fine-tune the Titan II LE using level, crossover frequency, placement and phasing.

The Titan II LE Powered Subwoofer

Thank you for your order and congratulations on becoming the owner of an ACI speaker
system. The Titan II LE powered subwoofer(s) will provide you with many years of listening
pleasure!

The Titan II LE was designed to please music lovers who don’t want to fashion their habitats
around large, obtrusive boxes. Attractive and reasonably sized, the Titan II LE takes up little space
and there are many options for room placement including “hidden” placements. The attractive
cabinets are excellent as a small end table or plant stand. Hookup to any music system is easy!
The Titan II LE is a fantastic addition to your video system as well. The Titan II LE will allow you to
“feel” the impact and power of The Matrix, Blade, Hunt for Red October, Last Action Hero, The
Fugitive, etc, etc. We know you will enjoy many years of satisfaction with your Titan II LE(s)!

The Titan II LE has plenty of power to move a lot of air. The downfiring driver reproduces all
low organ pedals, symphonic bass drums, tympani, video special effects and synthesizers with
stunning realism. Equally important, the Titan II LE does a fine job with the subtle but musically
critical qualities of difficult instruments such as piano and string bass.

The enclosure is constructed of ¾” non-resonant high-density fiberboard with extensive
internal bracing. Solid hardwood panels coated with multiple layers of clear or black lacquer grace
the exterior. The specially developed ACI 12” driver has extremely long excursion and a balanced
cone-motor system supported by a heavy cast-frame that operates with very low distortion. A
specially developed rubber surround precisely terminates the stiffened fiber cone.

Performance

The electronics of the Titan II LE performs the following functions:

• Gain is controlled at the INPUT LEVEL with a precision Alps pot. This also acts as the volume

control for the Titan II LE. Once the volume is set, your volume is controlled by your main
system.

• Two additional LOWPASS FILTERS A&B, precision Alps pots, allows the user to select any

crossover frequency from 35 to 250Hz. These two separate 12db/oct filters provide exceptional
control for interfacing the Titan II LE in a music system.
