ALTI4 - 2-way 4" pendant speaker

"Pure sound, hanging around."

The ALTI4 is a 2-way pendant loudspeaker featuring a 4” driver combination with a coaxially mounted 1” soft dome tweeter and is fitted with a phase plug for excellent off-axis performance.

The 2-way combination with a high-quality polypropylene enclosure and acoustic engineering craftsmanship guarantees premium performance for demanding applications. A continuous power handling of 30 Watt (RMS) and maximum power handling of 60 Watt is achieved. Connections are made through a terminal block connector behind the rear cover, accompanied with a power tap selector switch for the tapping of a 70V/100V line transformer with tappings for 24W, 12W, 6W and a 16 Ohm bypass connection.

Mounting the speaker is done through a connection cable with two integrated steel cores for suspending with an additional drop safety. Fixation is made through two snap-hooks on one end and a dual Gripple™ fixation on the other end. The included cable length of 3.5 meters offers possibilities for a wide variety of ceiling heights. An innovatively designed rear cover of the speaker can be placed after installation and hides the connection and suspension on the speaker end. The ceiling end connections are covered through a cable cover.
