No surprises here, but direction of travel may interest some.

No special bias sauce, it seems.

I suppose it was only a matter of time...http://www.audio-gd.com/HE/V1HE/V1HEEN.htm...

Merely the horn-loaded combination of an S2 and a Fane 8M, driven by a full range Melquiades, is a world away from any ordinary speaker. It requires musical intelligence to arrive at that conclusion in the first place, iterating over a million possib...

It is an opportunity to pursue the common obsession with all things military: the largest formed transparent structures are probably fighter jet canopies. Acrylic would be optimal, vacuum formed at elevated temperature. Were Jessie dazzle still here ...

Surely questions of optimal topology need cognizance of the material to be played. If someone listens only to lieder, say, two drivers are sufficient. It is only those of us trying to reconstruct a Wagnerian orchestra that need multichannel breadth....

Low frequency damping is a huge problem in architecture, and that it is poorly solved tells you it is hard. Simplest improvement would be to use a viscoelastic material with better properties than rubber and to embed weights within it. Perhaps obtain...

The worst of it is there is no logic in using carbon fibre. They could have made a case for ekoa, but that would require some imagination. ...
|
|
Many thanks, Romy: all is now well....
|
|
Apologies for the primitive question, but has anyone optimised a snubber for Romy's full range circuit? My implementation does not have one, and I am for some reason now starting to get ringing on start-up of one channel....
|
|
The problem is that each record varies along more than one dimension - composer, performer, performance context, etc - whereas the physical organisation has at best two dimensions: column and row on the shelf. One solution is to apply a dimensionalit...

I know it does not make the project any smaller but is not the sloping part of the ceiling in contiguity with the external roof? I am sure your neighbours will not mind a couple of chimneys coming out of that part of your house......

He might argue were it not for the market of the deaf he would not have the money to experiment for the benefit of those few with musical hearing. But it is odd that the desire to maximise his creative leverage has not yet compelled him to move into ...

Surely the psychology here goes deeper. Lamm does not like the very idea of a remote control, for that subjugates the device to the user. Each installation is for him an altar to his irreplaceable godhead, worshipers must come to it in prayer, not ...

Guys, it is worth thinking about where the computer attributable noise is best intercepted. Since the signal is digital all the way to the DAC, it is sufficient to optoisolate the USB connection. If your DAC runs the USB traffic asynchronously al...

The narrow portion of the midbass horn is surely begging to be inside a chimney, or a structure made to look like one, protruding through the roof. I am sure birds nesting on the back chamber will not impair its functionality, though it may be a pain...

Danley, however narrow his focus, is intelligently inventive. It is hard not to wonder what he would do if he had a refined ear to hand, so to speak....

I know he has implemented it (near) full range, but perhaps it could be a way to shrink low frequency estate? Or will it stand to an uncontorted horn as an insect ey...

That is given in the psychophysics: binaural phase offset sensitivity goes up with wavelength....

The reality is that PP's consumers encourage its business practices. It is rather like a woman complaining about an abusive boyfriend, only to return to him again and again. When those outraged by being lied to, by being kept waiting for years, are i...

The fan is given as <15dB at one meter, which is about right on my estimation, though I have not measured it in my unit....
|
|
I doubt PP evaluate their products with anything like your playback, or even mine. Their success is likely accidental, but how rare an accident is not something we can conclude on without wider testing. In the EU it is easy, for anything bought onlin...

...by a company in the UK, as discussed here before.http://www.powerinspired.com/ag-series-ac-regenerators-i-25.htmlWhen it comes to amplifiers, those who conflate a topology (e.g. SET) with a particular implementation of it are rightly mocked here, ...

Diagonals are hard to make attractive in any design: you can avoid them by using plates where a diagonal buttress is required. Have a look at the way Dieter Rams did it in his bookshelf geometry, now marketed by vitsoe (https://www.vitsoe.com/gb/606)...

I have film in that position; I actually meant the 1000uf+ caps in the power supply. Hard to get those in film.... ...
|
|
Thanks, Romy. What about drift in the driver bias, etc?I suppose the liveliest component, in terms of dramatic breakdown, is the electrolytics. I have been thinking of changing to film, but in that size they are hard to find at reasonable prices....
|
|
Romy, now that there is more than one Melq in the wild, may we have some tips on your approach to maintenance, i.e. what parameters/tubes you generally check/replace and how often? I know the 6 channel version will be different, but there are nonethe...

Placing a tool, any tool, even one subserving a civilised function such as playback, within an environment where aesthetic criteria ought to dominate is always tricky. Fidelity to function is rarely attractive by itself, whatever contemporary arc...

You could use this material for the louvers:http://www.ixperial.net/epages/63772936.sf/en_GB/?ObjectPath=/Shops/63772936/Products/BANDMW0011It woven from fibre created by melting volcanic rock. It has a curious bronze lustre, so would go very well wi...

There is space for a set of automated vertical fabric blinds to be attached underneath the bookcase...it could even run the length of the entire space, including in front of the alcove. You can of course angle vertical blinds arbitrarily, and perhaps...
