Alexandria XLF: Idealism and Technology
Dave is an idealist, but he is also a disciplined empiricist. Dave the idealist insists that no detail is too small to be scrutinized. Dave the empiricist knows that it's all too easy to be seduced by the technological promise of a given part. See how these two defining characteristics played out in Wilson's new flagship loudspeaker.
XLF Port Technology
It’s relatively easy to achieve flat frequency response in an anechoic chamber. But, in the real world, the sound of loudspeakers is highly dependent on the room they’re in. Room-induced bass non-linearities are problems that have generated lots of solutions. One of the most common is active equalization, often processed in the digital domain. The downside is that insertion of an electronic equalizer into the audio signal produces deleterious audible effects in the rest of the frequency spectrum.
Developing the Convergent Synergy Tweeter
Tweeter technology evolved in the first decade of the new century, with new designs using exotic materials such as diamond and beryllium. Proponents of these designs extolled their ultra-wide bandwidth, in some cases extending to beyond 50 kHz. The engineering rationale was that pushing the tweeter’s resonant frequency (or break-up mode) well above the audible spectrum would produce greater linearity within the audible range.
