It looks identical to its 8200 family siblings, 8240A, 8250A, but the new 8260A is the largest yet.
On top of being larger, it is also a three-way model. How does Genelec get a three-way configuration out of what looks to be a two-way speaker? The mid/high driver is a coaxial midrange (5-inch) and high (0.75-inch).
As a three-way speaker it also has three amplifiers: 150 W driving the 10-inch woofer and twin 120 W amps driving inputs to the midrange and high-frequency drivers.
The coaxial driver uses Genelec's Minimum Diffraction Coaxial technology along with its Directivity Control Waveguide technology. The enclosure is die-cast aluminum, with Genelec's Minimum Diffraction Enclosure design.
The 8260A uses Genelec Loudspeaker Manager (GLM) software to control crossovers, driver EQ, alignment, delay, response, surround configuration and speaker calibration. An AutoCal calibration system ships with the 8260A.
