"Don't feel like hanging around?"

2-way 4" design wall sound projector

The ALTI4M is a variant of the ALTI pendant speakers, featuring a die-cast mounting bracket for wall & ceiling mount purposes. This allows the same audio system design and identity throughout the entire installation in case some areas are not allowing pendant solutions to be used due to the ceiling heights or structures. Acoustics and construction are identically crafted, while connections are made through AWX-5 connectors.

The ALTI4M features a 2-way 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.

The wide opening angle of the speaker guarantees an exceptional dispersion in all different kinds of applications and locations with high ceilings and large open spaces. The carefully matched components and construction guarantee optimal coverage over the entire frequency range.


A die-cast mounting bracket makes wall & ceiling mounting possible at any desired angle. This swiveling bracket allows the same audio system design and identity throughout the entire installation. Some areas do not allow pendant solutions to be used due to the ceiling heights or other structures.


Thanks to a special coating applied to the drivers, the ALTI series are also suitable for use in applications with high levels of humidity such as outdoor terraces, bathrooms, or many more!

Weatherproof connectivity and adjustments in one connection

The AWX5™ connector is a specially designed connector that prevents the use of extra equipment and adjusting to a speaker system for setting the desired power tapping and maintaining an IP55 waterproof connection. The power setting can be made by simply rotating the connector. On the cable part of the connector is a white dot displayed. Depending on the position of the white dot, the desired power can be selected. When inserted a screwable outer ring with an inner rubber seal guarantees a superior connection in any type of weather condition. The power tapping can be set in 3 adjustable steps for 100V and one step for 8 Ohm standard low impedance applications.
