From Bowers & Wilkins:
"The 686 is the baby of the 600 Series bunch, but doesn't lack for the technologies and features to deliver outrageously good sound in smaller room settings. Mount a pair on a wall or stand, or simply sit them on a shelf or table for a compact stereo system or as surround speakers in a home theater set-up.The 130mm diameter Kevlar cone bass/midrange is based on a tried-and-trusted B&W design, but its new fixed center bullet helps to smooth the response in upper frequencies. Also, by setting the bass/midrange closer to the tweeter than in equivalent earlier speakers, we have improved the integration and vertical dispersion of sound from the two units. The Nautilus tube-loaded, aluminum dome tweeter, featuring a new surround material to improve spaciousness and imaging, adds needle-sharp top end all the way to 50kHz and beyond."
