Product Description

Designed primarily for soffit-installed mains applications, the Arcturus leverages the same coaxial and axisymmetric technology from our well-regarded Quasar model. What sets the Arcturus apart is its unique integration of twin ring radial neodymium SEAS subwoofers – a design that delivers some of the lowest distortion and most linear output ever measured in our products.

These ultra-low distortion, exceptionally linear subwoofers feature a unique split-gap twin ring radial neodymium motor. The result? Exceptional symmetry and motor strength, even at extreme excursions. Put simply, these are the best 26cm subwoofers we've ever engineered or measured.

The Arcturus also integrates the same electronics as our Quasar model with an added 2RU remote AMP/DSP pack which will require top and bottom venting. The sealed Valchromat cabinets are stiff, dense, and well-damped, with none of the chuffing or group delay of ported designs. The ultra-rigid 38mm laminated front baffle handles the impressive output of the twin 26cm subwoofers, while the radiused insets for the subwoofers eliminate potential lip shadow from the tall boy surrounds.
