Eighteen Sound adopts Powersoft’s IpalMod tech

Powersoft has announced that Italian speaker manufacturer, Eighteen Sound, is the latest transducer specialist to implement the company’s patented IPAL technology.

Eighteen Sound has designed its new iD Series transducers to couple perfectly with Powersoft’s Differential Pressure Control (DPC) technology, the core technology behind the company’s patented IPAL (Integrated Powered Adaptive Loudspeaker).

In order to implement this technology, Eighteen Sound has adopted the Powersoft amplifier hardware module, IpalMod, which overcomes the limitations of traditional transducers to produce what the company describes as ‘unparalleled’ output at low frequencies. It does so by featuring a zero latency pressure-sensor feedback, applying real-time correction to maximise Eighteen Sound high efficiency 18in and 21in transducers.

In taking the decision, Eighteen Sound recognised that despite the improvements made in design, materials and manufacturing processes 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 non-linear behaviour.

Powersoft’s IPAL features a low frequency-dedicated system that integrates an 8.5kW high-power, high performance switching mode amplifier module (the IpalMod) together with ultra-high motor force electro-dynamic transducers — the 18iD and 21iD Eighteen Sound speakers.

Giacomo Previ, Eighteen Sound’s sales and marketing director, commented on the technology: “Powersoft’s IPAL 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 2-Ohm impedance. In order to fully 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,” said Powersoft brand and 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,” Fanicchi concluded. “On top of that, the IPAL system ensures consistent transducer performance over its entire life cycle and balances transducer differentials in every subwoofer application.”
