Brexit Day

Feels very strange, like the early days of WW2. Theresa Chamberlain and Adolf Merkel eye each other across the English Channel and drop leaflets, each to convince the other to surrender. The Phony War, as it was known. My son asked me last night what would have happened if Churchill hadn’t been elected, and I had to reply, “We find out after tomorrow…”.

Movie “Arrival” ; an absolute MUST WATCH!!!

Movie “Arrival” ; an absolute MUST WATCH!!!

The movie “Arrival” is an absolute must watch on many levels. No spoilers, but approach it like “2001” rather than “Star Wars”…

Don’t go against Nature: The Romans sweetened their wine with dissolved lead, and look what happened…

Don’t forget, Alacrity Audio’s Acoustic Induction promotes the production of a Standing Resonant Wave, not at their own Resonant Frequency because they do not have one, but at EVERY frequency and complex wave-form with which they are driven, a previously demonstrated unattainable state for any enclosed or vented volume of air.

“The Romans sweetened their wine with lead. It was not obvious that the painful and lingering deaths that resulted — decades afterwards — were caused by the metal dissolved in the wine.” (Taking the Medicine, by Druin Burch).

Don’t go against Nature: The Romans sweetened their wine with dissolved lead, and look what happened to them. GM, Aspartame, Glyphosphate, margarine, low-fat diets, loudspeakers that try not to produce any Standing Waves; all these things we’ve been told are “Good” for us are actually turning out to be bad because they are not as Nature intended.

OK, so this post sounds like it’s taking on the form of one of my Sunday Sanities, but it’s not. It’s more of a “why you need to bring Standing Waves back into your audio-reproduction equipment” kinda post.

All sounds are generated by resonating structures.

Therefore, all sounds are resonant Standing Waves, maintained by both…

Audio Induction; how it works.

The easiest way to visualize what’s going on in those boxes is to imagine them as working like a coil (inductor), as opposed to all other loudspeaker cabinets which act more like a condenser (capacitor).

Under “d.c.” acoustic conditions, the bass unit reaches it’s maximum excursion boundary and sits there. Pressure (the applied signal) equalizes through the system and the acoustic resistance (flow of air) falls (stops), although an acoustic potential (‘back-EMF’) remains. When the d.c. condition is removed, the acoustic potential discharges in the opposite direction to the force that was previously applied, producing a classic cosine waveform.

This is the very definition of an acoustic inductor.

Under “a.c.” acoustic conditions, the bass unit must dissipate the acoustic back-EMF in the cabinet before it can change direction and complete the next part of the waveform. Fortunately, the direction of collapse for this wave…

Malvern Audio Research Visit.

Success comes in many forms. For some it’s Fame or Wealth that counts. Others seek power, responsibility or thrills. And there’s a section of people that just draw satisfaction from a job done well.

Our visit to Malvern Castle passed-off without a hitch. Mark of MingDaUK fame has been a fan of our loudspeakers for a long time now and, having had a pair to himself for the weekend at the Indulgence show, he finally sent out a stagecoach to demand our presence in Malvern Towers. Passing through the portcullis with it’s guards and their pikes, we were welcomed by his fair maidens and shown to his inner chambers.

Mark and his MAR pal Raj are wonderfully warm people, and a relaxed atmosphere pervaded the whole afternoon. I love being in the presence of other Mavericks; the system we listened to was a mixture of prototypes, finished goods and my loudspeakers, just like being at home, coupled with the same “watch where you sit” approach to circuit board storage.

And, oh my, doesn’t it show when you’re in the hands of people who know what they’re doing. If I were to describe the stereo imagery at one point, I’d say “ghostly”, not because it seemed ethereal or insubstantive, but because it actually made me jump out of my skin.

So, after a state banquet, it was proposed that there be a conjoining of our great houses, the sprawling Malvern Estates and our humble HiFi Cave (“mind where you sit”), sealed with a sample pair of Caterthun8s.

“Hurrah!!!”
