The Jamos are dipole speakers in the bass and midrange. Physically, they consist of two 15″ woofers mounted one above the other on a 48″ high by 19″ wide, slightly curved, rigid baffle, with the midrange driver and tweeter mounted on the same baffle above. Rather than being in an enclosure of any kind, the two woofers and the midrange are open in the back. The baffle is supported behind by a central metal brace, and the whole back is covered with a grille cloth so one does not see the working back ends of the drivers. The speaker is unusual but elegant looking. The review sample had a spectacular yellow baffle, with black grille cloth behind and removable black front grilles. The tweeter, while baffle-mounted as noted, has by its nature a closed back. But up into the treble, the whole speaker really operates as a dipole, so there is the usual dipole acoustic null to the side. This absence of sideways radiation opens up the possibility of greatly minimizing sidewall reflections.
