Where's My Mule..?

-

 


I mentioned yesterday that I wanted to upcycle my dad's old Wharfedale speaker drive units and crossovers in a new build. I think I might just use them as a test bench to try out some old cabinet ideas of mine, and maybe resurrect some very old technical ideas from the fifties and before. So, I intend to build a standard mule speaker baffle that will allow me to house the active bits in one piece, so I can swap out various configurations of box behind it. I'm going to go for a laminate of the cheapest particle board - for economy and because it's dense and reasonably homogenous - and thinner ply, for its machinability and finish. Facing the dense core with good ply will also make it more durable in the swapping between boxes for testing scenario.

I've got a few ideas of my own to try: some going back to fag-packet scribbles thirty or forty years ago that were never tried; and some very much older ideas that never gained mainstream traction for long, but which I've always thought were good ideas that just needed taking further. All involve bracing and porting techniques: for this series of experiments, I'm sticking to twenty litre boxes, as that is the designed infinite baffle load for the Wharfedale bass-mid driver of the Linton design and cheap and simple to construct/modify. Where I go from there is anyone's guess, as this - as usual - is jazz. This time the image is of a pair of Linton 2's. Keep you posted...

Of Feedback & Wobbles

Many years ago I came up with an analogy for poorly damped feedback loops. The feedback loop that prompted this frankly tart analogy was indeed a horror. Anyone who remembers shame-faced their first attempts at clutch control resulting in the good old kangaroo launch across the lights only to stall in the middle of the crossroads will have some idea of the kind of data transfer lag involved in said system. The analogy I made was that of a large blancmange. Untouched, a model of stasis and eminently stable and predictable; but prod the bugger and the resultant chaotic behaviour needs a very complex physical model and some very decent computing horsepower to predict its outputs, if at all. The system in question was a large and complex audio-visual display at what eventually became 'The Electric Mountain' in Llanberis. We were ultimately contracted to maintain the thing having been witness to and peripherally involved in its installation. Certainly not involved in its des

Sister Ray

Ray Keats - aka Ann Key - local artist & family friend, died this morning. She'd been ill for some years, but never let it get in the way of her work or of tending to the massive network of friends, colleagues and fans she had accumulated over the decades. Her house on the High Street of Rachub, just below where we live - a former cockle factory(!) - bought many years ago when she and her late husband Ronald moved here from Manchester to set up home in Yr Achub, is currently still home to her paintings and drawings, and the front window displays her work, including the last drawing she made in hospital, just days before she died. Her good friend Colin has been a diamond in her latter years, looking out for her and just being there when she needed him. She will be much missed by this tiny community of ageing bohemians up here in the hills, but suffice it to say, George, her cat, will be well looked after now she's gone.

A Time of Connection

I was just reflecting on the vacuum of continuity that's left behind when someone dies: that sudden sense of disjoint, of fracture, in one's personal history that takes one completely by surprise at the oddest moments. These pinch-points in memory can often yield some surprising revelations of fact about periods in one's past. One such occurred to me tonight, tending my rather lazy meal of pizza in its journey from shrink-wrap to mouth via the oven. Al's recent demise still catches me out from time to time: the space he left bounded by forty plus years of friendship. But the thing that struck me tonight was just how much change was happening on a personal and social level in the very early years of our acquaintance. Between moving here from Birmingham in September 1980 and our buying our first proper house eighteen months later, all manner of things occurred that would chart the course of our lives to the present day. At around the time of our meeting Alan & Irene [
