Wharfedale Diamond 155 speaker



 Wharfedale  Floor Standing Speaker

 Diamond 155

Naturally cabinet design was not forgotten in amongst all the other technology. Rectilinear cabinet shapes were chosen to maximize the internal volume and provide the deepest, most extended bass response. Again the research from the highend Jade series was incorporated to elicit the latest advance in loudspeaker reflex loading – the Slot-Loaded Distributed Port.

Exiting at the base of the speaker cabinet, the refl ex port is loaded by a slot created by the plinth. This equalises the air pressure to mimic that inside the cabinet allowing smooth transition between the pressure variation in the cabinet and the low frequency sound developed in the room.

Cabinet walls and internal bracing were also incorporated in the ‘Virtual Speaker’ model, with the help of Delayed Cumulative Spectral Analysis that ruthlessly reveals panel coloration in all its forms. Using this technique Wharfedale engineers formulated a cabinet panel construction of multigrain faceted boards bonded together to damp annoying High-Q resonances and block internal sound leakage. The effect is that the ‘noise’ from cabinet walls is buried more than 35dB below the driver output. In Diamond 100 all you hear is crystal clear music from the drive units without any attendant coloration from the cabinet. Again computer analysis helped refine this novel technique, but the result is an audibly superior bass performance of great articulation and clarity.

The Real Test
That doesn’t mean that Diamond 100 is purely a computer design, clever though that might be. This ‘Virtual Speaker’ is simply a tool that allows the Wharfedale engineers to explore all facets of the loudspeaker ’s performance before starting listening tests. In the final evaluation weeks are spent fine tuning the acoustic performance using a wide variety of music in Wharfedale’s five listening rooms, each of which mimics the kind of domestic environments the Diamond Series are likely to be used in. Only when the acoustic tests are deemed truly satisfying are the loudspeaker designs signed-off for production, ensuring that each speaker model fulfils its eventual owner’s dreams of musically enjoyable reproduction from Britain’s Most Famous Loudspeakers.

Optoma HD25LV

Full HD 1080p

Full HD(1920×1080) has twice the resolution of standard HD. HD25LV is compatible with HDTV broadcasts and high–definition media to project impressive full 1080p images and video in their original digital brilliance.


HD25LV testing

3D Technology
HD25LV supports HDMI 1.4a 3D playback, including 3D 1080P Blu-ray, 3D gaming consoles like PS3, XBOX360 native 3D games, and 3D broadcasting signal, just connect Full HD 3D player directly to HD25LV via HDMI, you can instantly become part of a fantastically immersive experience at home. The 3D effect is generated by splitting this signal into two standard video streams, one for each eye. Using DLP® Link™ technology, the 3D glasses synchronise with the image on screen to filter each stream to the correct eye. Your brain then combines the two streams to make them jump into life.
