We are proud to introduce the "Ambience Reference" loudspeaker! A ribbon hybrid loudspeaker boasting an extremely high efficiency specification of 95dB. This is achieved while only using 25% of the power used to create the same volume as our standard models. These high efficiency levels are achieved with the use of special "rare earth" magnets, which help form the main part of the engine that produces the sound. These magnets are so powerful, they have to be freighted by sea as the magnetism interferes with delicate airline instruments. The higher efficiency now makes our loudspeakers suitable for amplifiers with lower output power ratings. These are now suitable for amplifiers with 5 - 10 watts, to a maximum power output handling or exceeding 150watts/channel. With the larger amplifiers, extreme sound pressure levels are achievable. To match the high
sound pressure level of this new ribbon section, we have had
to use 2 woofers in a newly designed bass section to create the
low frequency output. Retail price is in the order of $10,000 per pair! |
