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.

iw25 MEASUREMENTS
(All measurements made with Klippel Near Field Scanner in free space)
IS THAT REAL? YES, IT’S REAL.
The iw25 Listening-Axis Frequency Response is astonishingly flat and extended insuring the highest accuracy and highest-resolution available. This is the most accurate in-wall loudspeaker available.
(SOUND)POWERFULLY GOOD.
The CEA2034 or “Spinorama” data encapsulates the performance of a loudspeaker in a typical room. The iw25 “Listening Window” and Sound Power responses are ruler-flat, exactly the response that delivers accurate timbre, unmatched detail and coherence to the listener’s ears.
ACCURATE ALL THE WAY TO NINETY.
The iw25 horizontal off-axis response is predictable and smooth all the way to 90 degrees.
EVEN THE REFLECTIONS SOUND GOOD.
Horizontal reflections are the room reflections you hear the “most”. Ceiling and floor reflections typically factor into perceived sound quality to a much lesser degree. You can see the Total Horizontal Reflections (green) is extended and smooth indicating that the reflected sound from an iw25 loudspeaker is neutral in timbre and wide in bandwidth.
OVERLAPPING CIRCLES.
The iw25 offers wide dispersion all the way to the very top audio octave. Everyone hears wide-band, detailed sound.
GAIN CONTROL.
The “Directivity Contour Plot” shows the speaker’s dispersion characteristics using color to represent output magnitude. A quick inspection of the iw25’s contour plot reveals its very wide, but very uniform dispersion.
“SEE” THE SOUND.
Here is the data shown in the Directivity Contour Plot shown again on a polar map, making it easier to “see” how the sound is dispersed from the loudspeaker itself. The 0° axis represents the axis perpendicular to the speaker baffle.. The iw25 coverage is very wide and uniform, all the way to the top audio octave: >120° at -6dB even at 12kHz! Everyone in a broad area receives full-range sound with delicate, extended treble response. Only -90 to +90 is shown because the iw25 is an in-wall loudspeaker.
AS TALL AS IT IS WIDE.
The iw25’s vertical directivity is wide and predictable - especially for a two-way speaker with multiple LF drive units - making it easy to get uniform, broad-band coverage in every listening location.
