Moving Magnet Linear Motor Technology in Subwoofers Can Deliver Greater Conversion Efficiency and Sound Quality in the Lower Frequency Ranges
Los Angeles, September 22, 2014: Powersoft, a world-leading manufacturer of professional power amplifiers, announced that it will present working methodologies and loudspeaker application scenarios on its patented M-Force linear motor technology, which was introduced at the 136th AES Convention in Berlin [A Novel Moving Magnet Linear Motor: Convention Paper 9060, by Claudio Lastrucci]. The presentation will take place on Friday, October 10th between 2:00 p.m. and 4:30 p.m., and explores applications such as cabinet design using new, electro-dynamic transducers based on a moving magnet linear motor instead of a traditional moving coil.
The presentation, which will be conducted by Mario di Cola of Audio Labs Systems and Claudio Lastrucci — who both co-authored a new paper for this session — will demonstrate the practical use of M-Force linear motor technology with full measurement results. In the paper presented at the 136th AES, Claudio Lastrucci, Research and Development Director at Powersoft, articulated the benefits of this new technology, including improved conversion efficiency and sound quality in the lower frequency range as well as significantly lower distortion. Additionally, moving magnet technology offers considerably increased power handling, enabling it to reproduce upper bass frequencies with unprecedented level of quality and output. The presentation is open to all AES convention badge holders.
