User manual B&W CWMDS8 DATASHEET

[. . . ] CWM DS8 See nothing, hear everything Room acoustics, programme material and personal preference all influence the choice between dipole and conventional surround speakers so the decision is sometimes a compromise. [. . . ] In dipole mode the system is configured in dual 3-way format with two separate 80mm Kevlar® midrange and 25mm NautilusTM tube loaded aluminium dome tweeter arrays sharing the same bass driver.
