The amazing results offered by IPAL technology are possible thanks to the mix of several patented technologies developed by Powersoft:
Patented "Differential Pressure Control®": the core of IPAL control methods. One of the greatest limits on achieving outstanding acoustical performance is the lack of a global amplifier-loudspeaker feedback system, linking the electrical and the acoustical signal directly. The "Differential Pressure Control" (DPC®) does exactly this: it allows a differential pressure signal, mechanically obtained from the two sides of the moving loudspeaker membrane, to be fed to the amplifier just as any other electrical feedback signal. This grants a complete real-time characterization of the transducer and its acoustical load conditions, allowing for an input signal-to-SPL closed-loop design.
Patented "Virtual Speaker" technology. The Virtual Transducer® is an amazingly powerful tool, making the real loudspeaker behave according to any user-defined model. The speaker designer can synthesize any desired driver using a dashboard to set the Thiele-Small parameters, even when not physically achievable. The bottom line is no alterations to performance due to aging, power compression or acoustic uncertainty. The behavior of the real amp-loudspeaker system is defined by the mathematical model built by the user.Patented "Zero Latency" DSP on board for Equalization, Filtering, Limiting, Delay. All control methods need a processing unit to correct and filter signals received from available sources. IPAL technology is based on a control method whose effectiveness strongly depends on how powerful and fast the signal processing is. That's why we specifically designed a DSP core with an astonishing 10 µs latency on the critical analog in-analog out feedback path, allowing real-time corrections mimicking the "analog" feedback approach.
Eighteen Sound Ipal Speakers
Joining the IPALMod users family, Italian based speaker manufacturer Eighteen Sound delivers both 18” and 21” transducers, built around a 5.3” voice coil capable of handling up to 3600W program power.
These high outputs, high precision subwoofer systems allow up for high-quality low-frequency reproduction in the most demanding acoustic conditions.
Additional reliability is ensured by Eighteen Sound's proprietary technologies including ACS (Active Cooling System) increasing power handling capabilities and lowering the power compression figure; TSS (Triple Silicon Spider) enabling the speaker's response to be more linear, for a longer period of use.

B&C Ipal Speakers
The first company to join the IPAL development team at the very birth of the project was the Italian B&C Speakers: they studied, developed and manufactured a whole new generation of unique transducers together with Powersoft engineers.
B&C have been producing two IPAL compatible products since 2010: the 18IPAL and the 21IPAL, an 18 inch and a 21-inch speaker respectively. These speakers have been used in many professional applications, proving their exceptional performance and reliability standards in time.
