Purifi Audio: A Conversation About Amplifiers and Speakers

A new Danish audio company, founded by Bruno Putzeys, Lars Risbo, and Peter Lyngdorf was recently announced. The name is Purifi Audio, and as you can guess from the founders involved, the venture promises Class D amplifiers with record-breaking performance "unmatched by amplifiers of any operating class." But the new company will be doing more than amplifiers, since it also revealed a new 6.5" woofer with "magnitudes lower intermodulation distortion across frequency and SPL."

How Good Is Your Port
January 9, 2019 by Bohdan Raczynski

How Good Is Your Port

Ported enclosures are known to extend the low-frequency output of loudspeakers by exploiting the Helmholtz resonator effect produced by the compliance of the air inside the enclosure and inertance of the air in the port. This article looks at the problem of port nonlinearity to determine the correct port size, and the acoustic impedance of the port under high air velocity. This article was originally published in audioXpress, September 2001.
