Audio Myths: Why Narrow Bandwidth May Be Better also in the Time Domain.

This article expands the conversation around feedback theory for electronic circuits and audio amplifiers. Do we "really" need wideband open loop in audio amplifiers? The subject came up at the 154th Audio Engineering Society (AES) convention in Helsinki, Finland. Looking at the frequency domain, not necessarily, Jan Didden argued. In this article he looks at the question in the Time Domain. Narrow Bandwidth, High Open Loop Gain Amplifier versus a Wide Bandwidth, Low Open Loop Gain Amplifier in the Time Domain.

Legacy to Showcase New VALOR Speaker with Wavelet Digital Processor at RMAF 2017

Legacy Audio will premiere its new VALOR loudspeaker system at the RMAF 2017 show. Powered by an incredible 2750 watts per side, the VALOR is the first speaker to employ Stereo Unfold technology, licensed from Bohmer Audio of Sweden and implemented in the Wavelet Preamp/DAC/Processor. By combining a controlled-directivity front array for the initial wave-launch and a side/rear-firing ambient array, VALOR is said to be able to "reconstruct the natural sequence of sound arrival of the live performance space."
