In each article in this series, we will be looking at a differ ent aspect of the hi-fi signal chain – from sour ce to speaker . In view of its importance in the overall r eproduction of the sound, w.
If you examine the vast majority of cur- r ent – and past – hi-fi amplifiers and speakers, you will find the same story: a single channel of amplifi- cation handles the full audible frequency range of the system.
However , such an approach – “bi-amp- ing” or “tri-amping” the system – is far too complex and prone to err or to be a very practical approach in the consumer field. The Active Loudspeaker Back in the mid-1970s, multi-amping was almost unknown.
range of loads, and so on. The common method of dealing with these possibili- ties is to give a power amplifier four times the current delivery capacity it needs; and give it and its power supply the ability to handle the strange loads likely to be encountered in use and abuse.
To give an example from Meridian’ s product line, the DSP6000 includes four channels of 70W amplification.This is equiva- lent to about 1kW driving a conventional passive system. It is evident from these comparisons that an active system can produce sur- prisingly high levels from a significantly smaller amplification system.

Being able to deliver bass from an enclosure an eighth of the size is a use- ful ability , because it enables us to make loudspeakers that are physically the right size: on a human scale (see later). That means that they will fit into a room more easily , and take up less space.
Because you are near er to the left speaker , the sound takes less time to travel from the speaker to your ears – and you are further fr om the right speaker , so the sound takes longer to arrive.
If you remove, or disconnect, the “head”, you can hear very little definition. Psychoacoustically we are at our best listening in small spaces, to loudspeakers that have similar physical characteristics to a speaking human being.
