The Monitor HPD (High-Performance Dual) drivers were introduced as a major re-design of the Monitor Gold, with power handling figures improved considerably thanks to new high-temperature adhesives, ‘Tannoplas’ surround material and cones reinforced by ‘Girdacoustic’ struts to reduce cone breakup.Ī trio of drivers were developed to fit five cabinet models – the Arden, Berkeley, Cheviot, Devon and Eaton – and the drivers were sold also as kits complete with a crossover and terminal panel for the professional market or home constructor. The range was universally accepted worldwide but especially in Japan where it helped to establish Tannoy as a manufacturer of high-quality loudspeakers in the Far East. Lockwood Audio chose the HPD drivers for a range of studio monitors which found their way into many professional studios, continuing the legacy of the Monitor Gold. #Original tannoy dual concentric professional Reproducing the lowest bass notes requires that the driver move a large volume of air. Larger drivers are more efficient, requiring less excursion than a smaller driver to move a given volume of air. Larger drivers however require larger baffles and thus larger enclosures which can compromise the aesthetics of the speaker and hinder practical placement. Most modern speakers utilise smaller drivers in conjunction with a reflex-ported cabinet or transmission line, so as to allow for a slimmer cabinet design. While a larger driver is naturally capable of producing frequencies lower than a smaller counterpart, there is more to a speaker than a single driver and modern slim towers are quite capable of keeping up with their larger counterparts. However there is nothing quite like a big driver in a big cabinet where quantity and quality of bass, massive imaging and sheer volume and scale are concerned. #Original tannoy dual concentric professional.#Original tannoy dual concentric driver.#Original tannoy dual concentric drivers.
