The OPTICON 2 MK2 is a mid-sized stand mount speaker with 6-1/2" woofer and a 29 mm soft dome tweeter. It's a natural for high performance audio in compact to medium size listening spaces where it has room to breathe and deliver its dynamic and explicitly defined performance. The SMC used in OPTICON MK2's magnet motor system has very high magnetic permeability and very low electrical conductivity. It works primarily by minimizing eddy currents in the magnet system pole piece. This improves flux linearity, reducing the magnetic hysteresis. Resulting in a significant reduction of electro-acoustic distortion. The newly introduced OPTICON MK2 Dual Flare technique brings port design into the realm of aerodynamics - with exit and entry flares carefully designed to minimize turbulence. Dual Flare enables OPTICON MK2 reflex ports to remain laminar and work effectively to reinforce low frequency performance to a significantly higher volume level than would otherwise be possible. Dali's manufacturing process is designed to ensure that stereo pairs of speakers are built and tested sequentially by a single manufacturing technician, using components taken in the same order from the same batch. It's a process that helps ensure ultimate visual and acoustic pair matching.
