i4 and i4T

The i4 and i4T are the smallest, most discrete models in the i-series.  With 4.0" drivers, these two-way high performance loudspeakers are specifically designed for distributed music, paging and speech applications. 

 
The i4, and transformer equipped i4T models feature quality 4.0” low frequency transducers and 1" dome tweeters both housed inside a durable, IP54 certified ABS enclosure - available in Black or White  - with a fully protective front grille.
 
i4 is a low-impedance 8Ω model while the i4T features an internal transformer for use with 70v / 100v installations. 
 
For easy and secure installation, all i-series models are supplied with adjustable wall mount brackets.

Wharfedale Pro drivers Custom Wharfedale Pro drivers deliver a pure, unflattered and smooth sound. The 4.0" LF driver is smooth and accurate, giving a warmth and depth that is unusual in a plastic installation speaker. Meanwhile the 1.0" soft dome tweeter gives clear, but not agressive, high end. The silk diaphragm material is ideal for speech and paging purposes.
IP54 Certified
With IP54 certification, all i series installation loudspeakers are protected from limited dust ingress and are protected from water spray from any direction.

Full peace of mind - protection against extreme conditions.
Around the back
Connections are discretely placed around the back. Both the i4 and i4T use screw terminals for bare wire connections.
