This product is certified to meet the requirements of the European Union (EU) Electromagnetic
Compatibility (EMC) Directive (89/336/EEC). Because the permanent magnets attached to the
loudspeaker drivers produce magnetic fields, it is recommended that the product not be positioned in
very close proximity to computer monitors or television sets.

1. Introduction
Your new Avalon Acoustics Ascendant loudspeakers represent a true breakthrough
in the development of moving-coil loudspeakers intended for accurate music
reproduction. Upon initial listening, the immediacy and presence of a live
performance becomes instantly apparent. The intent is to closely reproduce the
original musical event, as opposed to creating a "spectacular" sonic character which
can impress upon first listening, but fail to satisfy over a long period of time.
The Ascendant accomplishes this goal by providing the transparency and clarity
which is lacking in many dynamic designs. Overall smoothness is achieved without
depressing the high-frequency response, a technique used in some products. Low
frequencies are rendered realistically and controlled, as opposed to a "larger than
life" perspective, which can impress, but compromises definition and harmonic
integrity.
This high level of performance is retained in virtually any listening situation. The
Ascendant has been specifically designed to elicit the finest possible performance
from any amplifier, tube or solid-state, due to its easy-to-drive nature. Similarly,
interaction with the room has been minimized, allowing ease of placement in a wide
variety of listening environments.
Your Ascendant loudspeaker was designed and built to the highest standards of
workmanship and performance. These standards are preserved through the test of
time by careful attention to component quality and meticulous testing of each unit
before leaving the factory. As a new owner of this Avalon Acoustics product, you
can be assured that you possess one of the few great loudspeakers the audio industry
has to offer.

2. Unpacking Instructions
Introduction
Your Avalon Acoustics loudspeakers were shipped in a heavy-duty crate to ensure their safe arrival. It is
recommended to save this crate for possible future use. Due to the weight of the speakers, it will require
two persons to un-crate them and position them for listening. Please arrange for your dealer or other
friend to assist in this project.
Contents
The shipping crate contains the following items:
Two loudspeaker cabinets
Two grille assemblies
The owner's manual
One set of six ApexCouplers
An accessory bag
The grille assemblies and owner's manual are contained in an outer compartment on the top of the
shipping crate. The ApexCouplers and accessory bag are packed together on the bottom of one of the
loudspeaker cabinets.
The accessory bag for Hardwood finished loudspeakers contains replacement grille pins, a small bottle
of furniture polish, and two lint-free polishing cloths.
IMPORTANT: It is imperative that the Apex- Couplers are utilized, in order to insure that the
bottoms of the loudspeakers are not blocked. This is especially important on thick carpeting.

2.1 Opening the Crate
The crate features a one-piece top assembly, which is fastened to the crate bottom with screws around the
lower perimeter. To unpack, remove the screws and lift the upper portion of the crate straight up (this will
require two people).
Next, slide each speaker part way off of the crate base so that the plastic bag can be unfastened from the
enclosure bottom.
Stand the speaker up and the bag can be slid off the top. Please refer to Figure 2.
Figure 2.1 - To unpack the loudspeakers

2.2 Installing the Grilles
The grille assemblies are behind a panel on the outside of the speaker crate. Remove the screws securing the
panel, and then carefully pull the grilles straight out. The grilles are installed with friction fasteners and press
into place on the speaker cabinets. Please see Figure 2.2.
Orientation of the Felt Anti-Diffraction Mask
The grille assembly includes a felt anti-diffraction mask. Should the felt mask be removed, be sure to note
the correct inside-outside orientation when re-installing it. The tweeter opening is beveled on the side that
faces the listener (away from the speaker).
Fig 2.2 - To install the grille assemblies.

2.3 Replacing Grille Pins
The grille pins installed on the grille assemblies are fragile and can be easily
damaged. Should any of the pins break, you may replace them using the following
procedure.
I . Place the grille assembly face-down on a padded surface (a towel
or carpeting).
2. Remove the damaged grille pin by pulling it straight out with a
small pliers or similar tool. Please refer to figure 2.4. Make sure
that the complete pin is removed and that there are no pin
fragments left in the mounting hole.
Figure 2.4 - Remove grille pin. Check for pin fragments in the mounting hole.
3. Insert the new grille pin in the grille pin installation tool (see figure
2.5).
Figure 2.5 - Insertion of new grille pin into installation tool.
4. Carefully pull the grille cloth away from the frame mounting hole. The
mounting hole must be clear of all obstacles during pin
installation.
10
5. Place the exposed end of the grille pin in the open mounting hole. Check to
insure that the grille cloth is not trapped between the pin and frame. Use a small
hammer and gently tap the new grille pin in place. Then, pull the insertion tool off
the new pin and verify that the pin flange is flush with the surface of the grille.
Please refer to Figure 2.6.
WARNING: Grille pin breakage may result if the grille cloth becomes
trapped between the pin and frame during installation.
Figure 2.6 - Installing grille pin into Ascendant grille frame. Note that after
installation, the grille pin flange is flush with the surface of the grille.
6. Reposition the grille cloth that was pulled away from the frame mounting hole
in step 4. The cloth should lay flat and wrinkle-free.
