Function

The ELAC 4 PI PLUS.2 is an add-on tweeter that is based on the technology of the omni directional ribbon tweeter.
This patented tweeter received its name from the physical definition for the maximum solid angle (= 4 Pi).
The ELAC 4 PI PLUS.2 can be connected to main speakers. The 4 PI PLUS.2 offers sound that comes off easily.
This add-on tweeter provides spacious sound for a broad listening area and can be used for stereo applications and
for home cinema. Even at a value of more than 50 kHz, there will be no resonances.
The ELAC 4 PI PLUS.2 consists of an internal network (it is called crossover network) with filters and protections. This
add-on tweeter can be easily connected to main speakers.
The crossover frequency and levels can be adjusted by means of a switch. Therefore, it can be adjusted to meet your
individual demands.

Installation

In most cases, the ELAC 4 PI PLUS.2 is positioned on the top of floor-standing loudspeakers. In some cases, interest-
ing results can be achieved, if the 4 PI PLUS.2 is placed behind or next to a main speaker. To ensure perfect omni
directional radiation, the distance between the add-on tweeter and reflecting walls should be 50 cm (minimum).

Impedance

The load of the amplifier is increased when two loudspeakers (ELAC 4 PI PLUS.2 and main speakers) are in operation.
However, in practice, the results of this are not worth mentioning because it only affects the trebles. It is just important
to ensure, that the amplifier is suitable for 4 ohms, regardless whether the main speakers are for 8 or 6 ohms.
