1 Introduction is the most technologically advanced high-energy transducer ever created. Our focused research over a period of four years has produced a range of advancements in each aspect of loudspeaker performance. Proprietary conductors and magnetic technologies, as well as new techniques in cabinet construction, have been combined with the first implementation of full range neodymium driver motors, for the expressed purpose of empirical improvements in all aspects of energy

2 Unpacking Instructions Introduction Your AVALON ACOUSTICS loudspeakers were shipped in a two heavy-duty crates to ensure their safe arrival. It is recommended to save these crates 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 another able bodied person to assist in this project. Contents The two shipping crate contains the following items: two loudspeaker

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. Please note that the binding post is on the back of the speaker. Be sure to slide speaker to end and not

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

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. 1. 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 fragment

4. Carefully pull the grille cloth away from the frame mounting hole. The mounting hole must be clear of all obstacles during pin installation. 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 ref

3 Wiring Instructions Introduction The crossover is encapsulated in a sealed, non-accessible chamber in the bottom of the speaker cabinet, to minimize the effect of vibration on the components. The ISIS is equipped with high-quality binding posts for connecting the speaker cables. Spade lugs are recommended for cable terminations. Connecting the Speaker to the Amplifier 1. Place the speaker in its approximate location, then lay the speaker on its side, using a soft surface to avoid sc

4 Break-in Period Your new AVALON ACOUSTICS loudspeakers have an initial break-in period. They will not perform to their full sonic potential when first installed in your system. This is partially due to a residual polarization of the dielectric materials used in 1 the crossover capacitors and internal wiring. As music is played through the loudspeakers, the electrical signal will gradually anneal these materials. Similarly, the suspensions of the drivers will reach their optimal

5 Maximizing Performance These details are imperative to obtaining optimum results from your AVALON ACOUSTICS loudspeakers. Break-in The break-in period is critical to maximizing sonic performance and should take place before other adjustments (see the discussion on page 11). The break-in should begin with three to six hours of quiet music, followed by 200 to 300 hours of loud and dynamic source material. Grille Assemblies The grille assemblies, with their felt anti-diffraction masks

Toe-In Adjusting the toe-in angle of the speakers is useful in tailoring the sound to best match the characteristics of your system and listening room. When the speakers are facing straight forward, they tend to create a large, expansive sound-stage, painted with broad brush strokes. As they are rotated toward the listening position, the image becomes more compact, with increased focus, creating a greater sense of intimacy. Pointing the speakers inward is also helpful in situations whe

First Reflection Points Since the ear/brain system tends to integrate the sounds arriving within a 10 millisecond time window, it is important to control the early reflections arriving from the sidewalls to the listening position. A hard-surfaced wall can produce a strong frequency-dependent reflection that can interfere with the reproduced sound-stage, as well as change the perceived tonal balance of the system. Therefore, damping these first reflection points is strongly recommended.

6 Care of Your Loudspeakers Cabinet (Hardwood Finish) AVALON ACOUSTICS’ hardwood finished loudspeakers are supplied with a special polish and two lint-free polishing cloths, in order to properly care for the high quality furniture lacquer. The following polishing instructions should be observed: IMPORTANT: Use the supplied furniture polish ONLY. Do NOT use cleaners that contain ammonia, strong solvents, or abrasive materials. Use of these materials can degrade, scratch, or even DESTR

8 Room Acoustics and Speaker Position Introduction The listening room forms the final link of the playback system, as important as any other component in the chain. Just as an otherwise superb system is handicapped by an inferior pre-amplifier (for example), so can a well-matched system be hindered by poor room acoustics. It is not necessary to listen to your system in a specially-designed sound chamber in order to enjoy it. In fact, a dedicated listening room usually requires additional

An Optical Analogy Let us use a visual analogy to aid our understanding of acoustics. Imagine that you are in a room that is lit only by a candle in its center. There is (approximately) a uniform amount of light cast in all directions. If a large mirror is held closely to candle, one half of the room becomes darkened, while the other half receives twice as much light. This is because there are effectively two candles now illuminating that half of the room, the real candle, and the virtual
