Eighteen Sound is the latest transducer specialist to adopt Powersoft’s IPAL technology, a low frequency-dedicated system that integrates an 8.5kW switch mode amplifier module (IpalMod) with ultra-high motor force electro-dynamic transducers.
Eighteen Sound has designed its new iD Series transducers (18iD and 21iD) to couple with Powersoft’s Differential Pressure Control technology. This is the core technology of the IPAL (Integrated Powered Adaptive Loudspeaker).
In order to implement the technology, Eighteen Sound has used Powersoft’s IpalMod amplifier hardware module, overcoming the limitations of traditional transducers by featuring a zero latency pressure-sensor feedback, applying real-time correction to maximise Eighteen Sound high efficiency 18-inch and 21-inch transducers.
In taking the decision, Eighteen Sound recognised that despite the improvements made in design, materials and manufacturing process in the field of low-frequency reproduction, the traditional amplifier/loudspeaker approach still leaves major issues unaddressed: transducers come with physical limitations and uncertainties are caused as a result of loudspeakers’ intrinsically nonlinear behaviour.
‘We at Eighteen Sound always work towards superb sound quality, even in today’s most demanding sound reinforcement applications,’ say Sales & Marketing Director, Giacomo Previ. ‘Powersoft’s IPAL technology allows system designers to achieve an apparently impossible mission – the transducers and amplifier module performances, enhanced by the equally stunning integration of each component via the IPAL real-time feedback control, makes for an amazing sound.’
Both IPAL-compatible transducers have a nominal 2Ω impedance. In order to integrate them into the IPAL system, and optimise performance, a pair of either model should be connected in parallel when matched to an IpalMod amplifier module.
‘Eighteen Sound is the second major driver company to buy into our patented technology, says Powersoft Brand & Communication Director, Francesco Fanicchi. ‘iPAL-based amplifier/loudspeaker systems offer unprecedented acoustic performance and complete control of the system’s sound reproduction – and we are delighted that Eighteen Sound has joined the family of users. IPAL and the IpalMod bring many benefits, dramatically improving the electroacoustic efficiency in terms of high SPL and sonic performance.
‘On top of that, the IPAL system ensures consistent transducer performance over its entire life cycle and balances transducer differentials in every subwoofer application.’
