Digital Phase is definitely an obscure company making EXCELLENT speakers. They have been making speakers with their proprietary 'acousta-reed' technology for over 20 years in Chattanooga, TN. Their response curve on all their speakers are ruler flat from 35hz-20khz (+ or - 1.5 db) and they sound incredible, easily on par with my Dunlavy SC-IVs. Although their website needs a lot of work, it does have some useful info here:
