The d&b audiotechnik E-Series is a range of small to medium sized point source loudspeakers of a multifaceted moulded construction to achieve the maximum deployment versatility. They utilize direct radiating low frequency elements with coaxially mounted high frequency sections. The cardioid B4-SUB compliments the E-Series loudspeakers. The compact and unobtrusive design makes these loudspeakers visually discreet, yet a combination of accurate directivity control, extended bass response and appropriate sound pressure levels, make them audibly impressive for such small loudspeakers. The design incorporates all the necessary fittings into small, lightweight enclosures, making the loudspeakers quick and easy to handle.
