Up for sale are my pair of B&W 800 Diamond in Gloss Piano Black in immaculate condition for reluctant sale with about 50 hours of music through them.,
Read the links attached for reviews by What Hi Fi and a few other authorities claiming the B&W 800 Diamond to be the best speaker out there period.
Worlds best recording studios use nothing else... Period.
These are expensive speakers, you have to be prepared to add some serious power, because you won’t know how good they are if you don’t. You also need to try a variety of cables with the 800D’s because they respond very audibly to changes in components.
You must spend time with positioning them to get the optimal placement, and that isn’t easy with 275 pounds of speaker, the good news is that they are on castors. If you aren’t prepared to do this you may never know what they can do. However, if you do they will reward you with absolutely terrific music, with detail, smooth treble extension, soundstaging, depth, PRAT, slam, muscular bass and a sense of intimacy that belies their size.
The 800D consists of two 10” sandwiched cone woofers, one 6” Kevlar® midrange driver and one 1” diamond dome treble driver. It’s big – each one weighs 275 pounds, stands 47 inches tall, is 25.5 inches deep, and just shy of 18 inches wide. B&W lists a frequency response of 32Hz-28kHz, plus or minus 3dB and a frequency range of -6dB at 25Hz and 33kHz.
Description: Three-way, vented-box, floorstanding loudspeaker. Drive-units: 1" (25mm) diamond-dome tweeter, 6" (160mm) woven-Kevlar FST-cone midrange unit, two 10" (250mm) Rohacell-cone woofers. Crossover frequencies: 350Hz, 4kHz. Manufacturer's specifications: Frequency range: –6dB at 25Hz and 33kHz. Frequency response: 32Hz–28kHz, ±3dB on reference axis. Dispersion: within 2dB of on-axis response over 60° (horizontal) and 10° (vertical) arcs. Sensitivity: 90dB SPL (2.83V/m). Harmonic distortion (second and third harmonics, 90dB, 1m): <1.0%, 45Hz–100kHz; <0.5%, 80Hz–100kHz. Impedance: 8 ohms nominal, 3.1 ohms minimum. Recommended amplification: 50–1000W into 8 ohms with unclipped program. Maximum recommended cable impedance: 0.1 ohm.
Dimensions: 46.5" (1180mm) H by 17.7" (450mm) W by 25.4" (645mm) D. Weight: 225 lbs (102kg) Each.
The 800 Diamond utilizes all new crossovers, which Bowers & Wilkins state, "are the simplest and best crossovers we've ever produced." The new crossovers use Silver/gold/oil Mundorf capacitors which result in a cleaner signal path than with previous 800 Series designs. Even the speaker terminals have been improved, designed in-house and made from oxygen free copper; the terminals are more conductive then the previous 800D's all brass terminals.
For those who, on a very high level, are interested in overall design concepts, B&W’s 800 Series speakers employ what is generally known as transmission line loading. Transmission line loading guides the rear energy away from the driver to reduce the smearing of leading edge transients caused when internal reflections return to alter the cone movement of subsequent excursions. This technique is what was used in the B&W reference “Nautilus” speaker, whose drivers taper into long tubes at the back of the three treble and midrange units and curve like a snail shell in the bass driver.
Though it has a surprisingly high sensitivity of 90dB, the 800D, absolutely loves power. More specifically, it loves current. The more current it gets, the better it sounds.
A piano can go as low as 28Hz and as high as 4.1kHz. I’ve never heard a single piece of music that covers this entire spectrum, but there are plenty of recordings that cover the top and bottom halves. When I play such piano recordings through superior speakers there is no change in the fundamental tonality of the piano, and you can sweep the frequencies from low to high in a smooth fashion. The 800D passes this test with flying colours.
The 800D can reproduce large-scale music loudly while still feeling intimate. If the music is a 110-piece symphony you will clearly hear detailed recreation of the orchestra in a large setting. However, it does make you feel like you’re at a private performance of the Chicago Symphony in Orchestra Hall and got to pick a seat that is close, but not too close, conveying the impression that the symphony is playing for you. How can this be? After thinking about it, it’s not the scale of the presentation, or even the sense of being in row 8 versus row 18. I believe that it is the 800D’s combined ability to accurately sound delicate and thunderous, combined with the slightly forward but very deep soundstage and surprisingly for such large, elegant-looking speakers, they seem to disappear from your awareness to leave the listener alone with just the music.
