The lower, ported, section of the EKSTRA houses not one, but two of the 134mm bass drive units. One unit is located on the bottom panel, facing the floor, whilst the second is located internally, directly above the first, in a sealed iso-baric arrangement, handling only low frequencies and acting as an integral subwoofer system. The low-Q port is specially tuned to enable close to wall placement of the speaker in most rooms.
Iso-baric loading allows deep, well controlled LF performance from a compact enclosure. This system takes great skill to execute correctly, and the very successful implementation in several of our other models means that we can approach this new design with confidence.
