Andrew Welker provides a few tips and tricks from the pros in terms of first settings of your Home Theater Setup, and what kind of music to use to test.
Andrew discusses the power handling of a loudspeaker vs amplifier power - the reason why this is a myth, standardization issues, what to do if you hear a 'thump', and what to do really quickly if you smell something coming out of your speaker suddenly.
Next in our series of Audio Myths: Soft Dome vs Metal Dome Tweeter: which one is better and why? It's hard to understand where this myth started: the idea that you can tell what a speaker will sound like by knowing whether it is a hard dome tweeter or a soft dome tweeter. So why do some people persist in thinking it is true?
Sibilance: that harsh 's' sound that you hear when listening to music or audio. What causes it? Are there steps you can take to reduce it when you're listening to music?
We often get asked about when to use speaker port plugs: should I use them? What do they really do? Why would I want to block a port if you went to the trouble of putting a port in?
Audio myths abound: it's astonishing all the misinformation we hear. Today we begin an intermittent series aimed at helping you separate audio myth from fact. Whether you're interested in picking out new speakers or just wowing your friends with your in-depth knowledge, you'll find something interesting in this article.
After graduating with a degree in Electrical Engineering Andrew went on to join the R&D team at API (Audio Products International) makers of Energy and Mirage product lines. He was working directly for API's head of engineering Ian Paisley, who was also a member of that handful of loudspeaker designers who participated in the NRC research project, and to quote Ian Colquhoun "one of the finest loudspeaker designers to ever grace this planet".
Andrew spent over 10 years at API and ended up being the head designer for all the Mirage products. Andrew is a brilliant loudspeaker designer who has a broad knowledge of everything audio and a particular expertise in the science relating to the omni-directional psychoacoustical effects of loudspeaker reproduction. Andrew joined Axiom in 2009.
