iw25 High-Output In-Wall Loudspeaker System
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.

IS THAT REAL? YES, IT’S REAL.
The iw25 on-axis Frequency Response is remarkably flat and extended, ensuring the highest accuracy and highest-resolution available.
(SOUND)POWERFULLY GOOD.
The iw25 CEA2034 measurements confirm smooth, extended Sound Power – the iw25 will fill a room with neutral, wide-bandwidth sound everywhere.


ACCURATE ALL THE WAY TO NINETY.
The iw25’s horizontal SPL response is smooth and controlled all the way to 90 degrees off-axis.
EVEN THE REFLECTIONS SOUND GOOD.
The iw25’s horizontal reflections are accurate and extended, so the reverberant field stays coherent with the direct sound.


OVERLAPPING CIRCLES.
The horizontal polar plot (normalized) shows the iw25’s dispersion pattern remains consistent across the audio band.
GAIN CONTROL.
The horizontal contour plot confirms the iw25 delivers controlled, consistent coverage across frequency.


“SEE” THE SOUND.
The horizontal polar contour plot makes it easy to see how evenly the iw25 disperses sound across its coverage area.
AS TALL AS IT IS WIDE.
The vertical polar plot (normalized) shows the iw25 maintains consistent dispersion vertically as well as horizontally.
