ASSOCIATED EQUIPMENT

The SCS3 is a very high quality sound reproducer and will

benefit from use with the best associated equipment. Since it is

extremely accurate, it will reveal sources of distortion generated

elsewhere in the system. For example, distortion resulting from

poor recordings or inferior electronics will be reproduced

accurately. Also, the quality of the interconnect cables and

speaker cables will significantly effect the performance of the

system.

POWER REQUIREMENTS

It is important to have enough power to play at the level you

desire without distortion. If high sound levels are desired, the

SCS3’s are designed to be used with amplifiers rated up to 300

watts per channel into 8 ohms. If you play the speakers more

loudly than the volume the amplifier can cleanly produce, the

amplifier will produce overload (clipping) distortion. The sound

will become compressed, strained, and in extreme cases,

obviously distorted. This distortion is actually non-musical

additional energy and since it is concentrated in the high

frequency region where the speaker is least able to handle it,

tweeters can be damaged in extreme cases.

Since the SCS3 provides a 4 ohm load to the amplifier, it is

important that the amplifier be rated to deliver at least 50 percent

more power into a 4 ohm load than it does into an 8 ohm load.

   Keep in mind that sound quality is usually much more

important than sound quantity. There can be large differences in

the sonic performance of two amplifiers of equal power, and this is more important than large differences in power. Most

everyone will be happier with a 100 watt amplifier of high sonic quality than a 200 watt amplifier of mediocre sonic quality.

For this reason, we feel there is no substitute for listening in making your amplifier decision.

   The question “how much power do I need?” does not have the simple answer most people expect because it is not

determined only by the loudspeaker’s efficiency, but also by the volume desired and the size of the room. If all three factors

are average, about 100 watts per channel is required. Each factor can raise or lower this amount by about three times.

  1) Usually, people who “don’t like music loud” can decrease their power to about one-half. Also, people who like music

loud should increase their power by 2 times or more. Most people fall within a normal range.

   2) A speaker with a low efficiency of 84dB/W-m will require twice the power of an average 87dB/W-m speaker and one

with a high rating of 90dB/W-m will require only half the power of an average speaker. The SCS3 is of  average efficiency

(87dB) and therefore can achieve average output levels with an average amount of power.

   3) A small room will need less power for a given loudness level than a large room. A very small room of 1000 cu ft (11' x

11' with an 8' ceiling) will require about half the power of an average size room. A large room of 6000 cu ft (20' x 30' with a

10' ceiling) will require twice the average power. If the listening room is connected to another room by a large open area, the

required power will increase, but not by the amount of the combined room volume. If the room has a “dropped” ceiling with

light panels, the ceiling will be almost transparent acoustically and the space above the ceiling should be added. If the panels

are heavy they will act as a more normal ceiling.

   With all this in mind, a person who doesn’t like to play music very loudly and has a small room can get quality sound with

as little as 50 watts whereas a person who sometimes likes to play loudly and has a large room may need 300 watts or more.
