The new series includes five models with surround- and center-channel designs as well as two new active subwoofers, all of which incorporate technology developments.
The new B&W lineup ranges from the floor standing 703 and 704 and stand-mount 705 pairs, through the HTM7 center-channel model and the adaptable DS7 dipole/monopole surround speakers. The resultis a variety of loudspeaker models that can be combined in numerous ways to satisfy a wide range of system needs (and budgets), while retaining reproduction quality.
Each of the 700 Series’ fresh designs spring from a handful of key B&W technology refinements, largely derived from the firm’s Nautilus loudspeakers. The new range features B&W’s unique,shaped cabinets with a one-piece multi-ply, sloping top and baffleâ€”a technique taken directly from the Nautilus seriesâ€”that contributes to freedom from both vibration and internal acousticreflections. The 700s’ tapered sides smooth any remaining internal resonances according to B&W.
The five new models retain the B&W FlowPortâ„¢ dimpled, computer-shaped enclosure vent, which helps eliminate turbulence for cleaner, â€œfasterâ€ bass.
The 700 Series drivers incorporate advances to meet B&W’s Balanced Drive concept, derived from the latest findings of advanced, laser-enabled distortion analysis at B&W’s Steyning ResearchCenter. Balanced Drive mandates the most linear possible transducer movement both electro-magentically and physically, over the widest possible dynamic range, reducing several seldom-recognizeddynamic distortions for audible gains in â€œdetail retrievalâ€ and dynamic integrity.
An all-new 6.5-inch bass-midrange unit is employed with variations across the new series. B&W uses a woven-Kevlarâ„¢ diaphragm material for its resistance to higher-amplitude breakup distortions,and benefits as well from important Balanced Drive refinements. A copper sheath and aluminum â€œcapâ€ at the magnet pole-piece together yield uncommon linearity of inductance over the full (and veryextended) range of the transducer’s excursion. Along with a revised bullet dust-cap arrangement, this reduces both linear and non-linear distortions for significant audible gains in detail,quickness, dynamic linearity, and high-output integrity.
The 703/704’s 6.5-inch Kevlar bass unit also employs the Balanced Drive motor concept, and adds B&W’s â€œmushroomâ€ construction with ring-girder design to enhance the stiffness for even greaterbass slam and dynamic accuracy. The family’s sole three-way design (the 703) gets an improved version of B&W’s fixed-suspension FST midrange, a candidly low-distortion, transient-capabletransducer with detail and texture, using a redesigned surround and fixed center â€œbullet.â€
In the new lineup this transducer features a flexible tapered-tube loading â€œenclosureâ€ that absorbs rearward energy for Nautilus-like clarity and definition even at very high outputs, in a versionthat permits mounting in the 700s’ more compact designs. And throughout the front-stage models, this tweeter is mounted in a separate â€œpodâ€ housing whose smaller baffle area and time-alignmentspromotes â€œairyâ€ and â€œ boxlessâ€ sound.
The 700 tweeter also incorporates its own Balanced Drive pole-piece copper sheath arrangement, yielding dramatically more linear inductance, and a redesigned coil-to-dome union for reduced mass withgreater strength; together these extend accurate, linear response to 50 kHz.
The 700 Series alsoemploys custom, air-core inductors throughout for minimized distortion, and careful circuit topology and physical layout to optimize signal transfer between amplifier anddrivers.
The B&W 700 Series begins with the model 705, a 6.5-inch two-way optimized for stand-mount placement. The HTM7 is essentially the same speaker with the same performance, re-engineered forcenter-channel use with a low-profile cabinet and spatial response optimized for center-channel use.
The floor-standing model 704 adds a second 6.5-inch driver, a bass unit covering only lower frequencies in a â€œtwo-and-a-half-wayâ€ configuration. The model 703 adds an additional, dedicated 6-inchFSTâ„¢ â€œsurroundlessâ€ midrange evolved from the Nautilus 800 Series, and employs dual-6.5-inch bass units together to produce more extended bass with greater ultimate output potential.
The remaining 700 Series member is the DS7, a unique, dedicated surround-channel speaker, a configurable design optimized for on-wall or shelf/bracket placement. The DS7’s shallow design (just 8inches in depth) is intended to encourage correct home-theater layout, as are its supplied on-wall mounting plates. Here, the 700 Series 6.5-inch bass/midrange and 1-inch tweeter are joined by dual,4-inch mid/high-frequency drivers on opposing surfaces: a user-accessible switch permits selection of dipole or monopole (in-phase) operation, as taste, room acoustics, or program type suggest. Asecond switch permits selection of the â€œin-phaseâ€ mid/high unit in dipole mode, while a third tailors the tweeter level to the acoustic needs of the system or environment. Further, the DS7 provides a12-volt â€œtriggerâ€ which allows the programming of dipole/monopole options depending on source selection with certain processors, i.e.: Dolby Digital, DTS, SACD, etc.
Four of the five new 700 Series models are offered in a choice of five elegant, hand-rubbed real wood veneers: Black Ash, Cherry, Roseunt, Walnut, and Maple. The DS7 surround speakers are availablein matte black or white. The 700s are available immediately, at manufacturer’s suggested pricing as follows:
