Mais conhecida entre n\u00f3s por “Nautilus Caracol”, esta caixa do fabricante ingl\u00eas B&W ( www.bwspeakers.com<\/a> ) ficou famosa pelo seu desenho revolucion\u00e1rio e por sua qualidade de som. Veja aqui alguns detalhes.<\/p>\n

Dimensions
\nHeight: 1210mm (47.6in)
\nWidth: 430mm (16.9in)
\nDepth: 1105mm (43.5in)<\/p>\n

Net Weight
\n110kg \/ 243lb (loudspeaker: 60kg base: 50kg)<\/p>\n

Freq. Response
\n25Hz – 20kHz \u00b1 0.5dB on reference axis<\/p>\n

Freq. Range
\n-6dB at 10Hz and 25kHz
\nPower Handling
\n100W – 500W into 8 ohms one amplifier channel is required for each drive unit. Electronic crossover supplied with speaker.<\/p>\n

Drive Units
\nUnit 1: High Frequency: 2 domed units of anodised aluminium of similar construction, 50mm and 25mm in diameter, handle the 880Hz-3.5kHz and 3.5kHz-25kHz ranges respectively. All drive units are completely mounted on silicone rubber O-rings to decouple the from the cabinet
\nUnit 2: Mid-range\/high frequency: From 220Hz to 880 Hz, a 100mm flat-fronted unit is employed to prevent the gentle cavity resonance found in conventional cone units at around 2kHz interfering with the output from the upper\/midrange unit. A rare earth magnet assembly with hollow pole is used to minimise the obstruction to the rear radiation from the diaphragm.
\nUnit 3: Bass: A 9.5kg (21lbs) magnet with a 100mm (4in) voice coil acts as the massive motor of the 300mm (12in) bass unit (10Hz-220Hz). This, when used in the exponential line enclosure, results in a high-pass behaviour so over-damped that the traditional second-order characteristic is replaced by two distinct first-order slopes and no stored energy. A 250 micron one-piece aluminium cone ensures coherent motion to beyond 1.5kHz.<\/p>\n

Finish
\nMidnight Blue, Black, Silver<\/p>\n
