Overview
The iw25 fully-enclosed in-wall loudspeaker is the remarkable sb25 model, with a mechanical enclosure to adapt it to in-wall mounting. All of the sb25’s performance attributes remain: robust, wide-bandwidth and dynamic sound with uncanny accuracy and naturalness. The ability of the iw25 to fill large spaces with full-bodied, thrilling sound is shocking. Finally big sound in background and foreground applications does not have ugly, or even visible!
The iw25 in-wall loudspeaker can be operated at low-Z (4-ohms impedance) or by employing its included internal power transformer at hi-Z (70V/100V) at 60W, 30W, 15W and 7.5W.
Like its sister product, the sb25, the iw25 discreet in-wall loudspeaker will have you rethinking how you deploy audio in your premium system designs.
