Wharfedale Diamond 9 SW250 Active Powered Subwoofer with 12" Woofer (EACH)

What makes a good hi-fi loudspeaker?

Well although opinions vary, Peter Walker - the founder of our sister company Quad, summed it up very nicely when he said you should get out exactly what you put in. This formed Quad's philosophy which is '...the closest approach to the original sound'.

The perfect loudspeaker should be like being in the studio, or at the concert where the music was recorded. It needs detail, subtlety, accuracy, a good and wide frequency response - above everything, it needs to be realistic. The speakers in this section are all class leaders and give an incredibly realistic soundstage. What might surprise you though is their affordability!

Choosing Wharfedale speakers means you get the finest sound quality available at the price with the reassurance of a company that has been at the forefront of audio engineering for nearly 70 years.

Wharfedale Powered Sub Woofers

The addition of a sub-woofer will add weight and authority to any stereo system, extending the frequency response much further than conventional bass drivers. With the Wharfedale subwoofers, the built-in amplifiers are engineered to provide a powerful response at these frequencies, while a continuously variable crossover provides seamless integration with the other speakers in the system. All models offer a phase adjustment for the additional matching of the sound.

In a multi-channel system, a sub is recommended to handle the ?LFE? or Low Frequency Effects channel of Dolby Digital or DTS sound. The PowerCube provides the impact and dynamics to really bring the soundtrack to life without ever sounding boomy or woolly.

Wharfedale SW Subwoofers
The SW-150, SW-250, SW-300 and SW-380 represent the state-of-the-art in home cinema subwoofers. With large format drivers and very powerful amplifiers, they are able to reproduce the true dynamics and scale of the original recording without compromise.
A unique curved cabinet (on the larger models) not only improves aesthetics, also significantly increases the overall rigidity of the cabinet, reducing resonance and overhang to almost negligible levels.
An advanced microprocessor controlled filter section preserves optimum signal purity, whilst offering the consumer the best possible user interface. Fully remote controlled (not SW-150) with four programmable memory settings, allow customization of crossover, phase and volume, all form the users listening position.
Advanced cone diaphram
The new KEVLAR cones introduced on all the SW-models are marvels of materials technology and application. Although huge, they remain completely controlled at all times.
Sealed enclosure (not SW-150)
A sealed enclosure offers improved control. It significantly reduces the ?group delay? effect ? essentially interference patterns between the moving air from the port and that coming from the driver, but also provides better driver damping- tightening bass and further reduces overhang.
Damping and extended voice-coil
Completely controlled even under extreme dynamics, the advanced voice coils allow the cone to travel to the full 24 mm maximum excursion with a truly linear pistonic motion.
High power amplifiers
A band new Class AB amplifier has been specifically designed for the models. Very low distortion, exceptional headroom, and a high internal electrical damping factor provide accurate control of the speaker, for performance well above the specification.
Advanced subwoofer processing / filter system
All subs use an advanced microprocessor controlled analogue low-pass filter section for sonic performance with a low noise floor. It is possible to switch all filters off if used in a high quality AV system.
Memory function with four settings (not SW-150)
Four memory settings are provided to store all of the calibration information for a range of uses, and be recalled at the press of a button.
Full remote control (not SW-150)
Users can set up the full system from the actual listening position and change easily without having to move furniture or otherwise access the rear panel.

Wharfedale has been leading innovation in loudspeaker design since 1932. Through the award-winning early drive units and loudspeaker its, to famous marques such as the ‘Airedale’, Wharfedale has brought n ow one of the fastest growing audio brands in the world, we currently have manufacturing base of over 1.2 million square feet, encompassing everything from capacitor manufacture to full production of over 600 different drive units, we offer outstanding value through complete vertical integration of every process and sub-assembly - even to the extent that we manufacture our own tools.

Wharfedale’s UK team of engineers design every detail of every product meticulously with complete freedom to explore new technologies and materials. The results are clear to see with significant technological and performance advantages over our competitor’s products. Cast alloy DPC* chassis; high resolution tweeters; Super Audio Capacitors; high-grade internal wiring; Bi-directional KEVLAR“ woven cones; high-temperature double and quadruple wound voice-coils and rare-earth neodymium magnet assemblies are just some of the cutting-edge features we have included in our current ranges.
