UK distributor Karma-AV has added Ascendo’s new planar subwoofer to its home cinema design portfolio.
At 30cm deep, the 28 Sub Pro Squared is a slender 28” passive sealed subwoofer delivering high output while occupying minimal space in the home.
German immersive audio scompany Ascendo developed the composite sandwich flat panel cone built from layers of rohacell, with the cone area equivalent to a 32” round subwoofer, following discussions with Arnaud Laborie, CEO of room correction specialist Trinnov.
The company has ensured the driver’s motor structure accelerates the cone, motor mass and coupled air mass. The design provides quality planar wave front with efficiency, high power handling and a low system Q. Combined with ultra-dynamic response, the shallow roll-off delivers sound with native speed and impact.
The 28 Sub Pro Squared is intended for baffle wall or free-standing applications as well as behind fabric or screen, ensuring woofers can be spaced closely together for coupling of bass array systems. The sub can reproduce single-digit infrasonic frequencies and also exceed the LFE cut-off frequency of 120Hz.
