CONNECTING THE SPEAKERS
Speaker wire can be routed through a drilled opening in the mounting surface for a hidden connection. The PowerPoint 1.2 uses
It is essential for proper performance that both speakers in a stereo system be wired in the same polarity. The speaker’s input terminals are color coded to facilitate this. The wire connected to the red ringed input terminal of each speaker should connect to the respective positive (+) output terminals of the amplifier; the wire connected to the black ringed input terminals should be connected to the respective negative
ASSOCIATED EQUIPMENT
The PowerPoint 1.2 is a very high quality sound reproducer and will benefit from use with high quality 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.
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 PowerPoint 1.2’s are designed to be used with amplifiers rated up to 200 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
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
2)A speaker with a low efficiency of 84
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 the PowerPoint 1.2 with as little as 30 watts whereas a person who sometimes likes to play loudly and has a large room may need 200 watts or more.
