All main technologies, which glorified the Bowers & Wilkins’ products, incarnated in these speaker systems. In addition to the traditional tweeter, which is loaded on a tapered tube, perfectly absorbing the rear radiation of the membrane, there are a midrange speaker with a Kevlar diffuser on hard suspension (Fixed Suspension Transducer), two woofers with composite diffusers, and the profiled bass-reflex port, the entire surface of which is covered with small dimples (they are used for reducing noises, being created by the stream of passing through the pipe air). The bodies of B&W 703 also deserve a special mention.
They do not have any right angles and the front and upper panels are a single unit – they are formed from a single strip of MDF, bent and fixed in such position. The rigidity of construction cardinally increases due to such solution, and the placement of the tweeter on a slanting upper wall improves the dispersion on high frequencies.
There are two pairs of terminals for the connection of speaker cables on the back panel of the body. Each speaker system is mounted on 4 rubber legs or 4 spikes, intended for its mechanical isolation from floor. High qualitative wood veneer finish leaves no reasons for criticism.
