Powerful & Well-Built Quality Speakers Fragile items are double-boxed and bubble-wrapped for protection Tannoy, high-quality audio performance delivered by two elegant speakers. Condition Report: Pre-owned. Good Clean Presentation. Overall: Light surface marks. In very good and fully working conditions. Description: Model: 633 Colour: Black Brand: Tannoy Enclosure Type:3 way closed box Recommended Amplifier: 10 - 100 Watts Frequency Response: 48Hz - 30kHz Sensitivity: 89dB Nominal Impedance: 8 Ohms Dimensions: 237 x 717 x 219mm (Width x Height x Depth) Speaker weight: 11.5kg / 25.9lbs Year:1994 - 1998 The 633 Tannoy floor standing models employs a near-symmetrical drive unit configuration, with a central 25mm (1) dome tweeter flanked by two 165mm (6.5) cone drive units. The lower one reproduces bass and mid-frequencies only. The upper one is a dedicated low frequency unit, reinforcing the bass output. The 633 enclosure is designed for low resonance behaviour and reduced diffraction, providing benefits in colouration levels, stereo imagery and distortion. Product highlights: 3-drive unit system uses two 165mm units to improve bass reproduction, depth and power. Variable thickness, injection moulded cones ensure accurate bass and midrange reproduction. Gold anodised aluminium dome tweeter for clear treble. Low diffraction rounded baffle for purer treble and imaging. Sealed (1B) enclosure gives smoothly extended bass. New, gold-plated, sliding link Bi-Wire terminal panel with improved cable access. Optional Upgrade: Spikes and Floor-Couplers to improve stability and bass. Tannoy, quality in sound Built on work that was pioneered with the extremely successful Sixes, Tannoy have produced a range which offers elegant, powerful, excellent sounding solutions which will appeal to those who want great performance at sensible prices. These loudspeakers are the result of the efforts of one of the most talented in-house design teams in the Hi-Fi industry, where all aspects of the Profile series were the responsibility of dedicated professionals. The Profile series loudspeakers are ideal for Home Cinema use as well as normal stereo applications. Their discreet design allows them to blend in with traditional and modem decors. The Profile range has benefited from Tannoy’s long experience in producing loudspeakers for recording studios world-wide and unlike most other loudspeaker manufacturers, Tannoy manufacture all the drive units used in the Profile series in-house, giving the engineers complete control of their design and build. Tannoy has long understood a simple fact: technology cannot answer all the challenges of high quality music reproduction unless it is combined with the insights provided by informed listening. It is this combination of technology, listening and years of experience that makes the Profile series of loudspeakers special. Loudspeaker Enclosures. Most loudspeakers are built into rectangular enclosures, not as you might suppose because rectangular boxes and high quality music reproduction have any special connection, but for a much more simple reason: theyre easier and cheaper to build. In fact, there is almost no worse shape acoustically than a sharp-edged rectangular box. The parallel sides help promote internal ‘standing wave’ resonances, which inevitably colour and muddle the sound output through the bass and midrange. In addition, the sharp external edges encourage diffraction: output from the tweeter is re-radiated by sharp cabinet edges, producing interference with the direct sound which causes the overall sound to become harsh and muddled. Think of interfering ripples around rocks from stones dropped in a pond, the ripples representing the sound waves. The shape of the enclosure in the Profile series addresses both problems. The angled sloping sides reduces the number of parallel internal surfaces, and those remaining are further broken up by other internal features: damping materials, internal shelves on the larger models, the cross-overs, and of course the drive units themselves. Meanwhile, diffraction is virtually eliminated thanks to the smoothly rounded sides. Considerations Compact floor standers, well-balanced tonal match with tweeter and woofer crossover. Strength: Clear sounds. Solid construction cabinet design. Bi-Wiring. Excellent balance and fair sound-staging. Clear sounds. Good bass and good midrange. Ideal Speakers for music. Subwoofer not needed, but optional consideration for home-theatre. Excellent design and look stylish without grills. Overall, Well controlled and very easy to listen to. Can punch a lot higher than first assumed. Weakness: Treble is uncluttered, but a little understated. Achieves optimal performance at high volume.
