Excellent -many thanks, Nick.

As I recall, they never did reveal the actual ceiling of the Lightning. I think service was classed as somewhere in the region of 55,000ft, but with pressure suits & enough fuel they passed 78,000ft & still climbing.

When I was talking to Lynn last night, she asked if I would pass on her gratitude to everybody here for all the kind thoughts and memories of Colin. She hasn't read anything yet -she's understandably wanting to take things one day at a time, in her own way, but she will when she's feeling a little ...

Well, you covered it anyway when you mentioned the extra signal effects. ;)

Agreed -a lot (far too many) of speaker designers tend to assume a voltage source / near infinite damping, which is probably a bit short-sighted as they've lost sight of the system context. Not all though, in fairness ...

'twas ever thus. ;)

There are lots of reasons why a supertweeter can (as in can ) have an audible influence. But almost invariably not for the reasons touted by the sellers, magazines, hi-fi fans etc. A few, in no particular order:

It depends what you actually call a supertweeter. They aren't ...

Yes, rest in peace my friend. I'm still in shock from when first getting the news. Colin was a true gentleman -never afraid to express his opinions, kind, generous to a fault and with a heart of gold, who'd do anything for his friends. I'll long miss the days we spent in his room fooling with his ...

Pleasure. Hopefully will be hauling a few more out of my store over the next few days.

I have to admit, even running just T/S and impedance (former largely derived from latter) I'm very impressed with the little Silver Flutes and the Peerless 8in in particular. You can certainly beat them, but they ...

More to come as time permits.

...at times like this, I could weep.

Peerless ['by Tymphany', give me strength] HDS 830869.

What a nice, quite affordable 8in driver it was. 'Was', because of course Tymphany have more or less pulled out of the DIY market, so it's a case of 'get them if you can'. Yes, there is an alternative ...

And another. One I've known well for a long time: Fostex FF85wk.

A nice little relatively high efficiency (for size / type) 3in wideband / fullrange with a modern (non-rotting) foam roll surround and a multi-layer paper cone, using a long-fibre base with charcoal-impregnated short ...

Next up, this little beast:
DT-25N.jpg

This is the Monacor DT-25N, a very compact, relatively inexpensive 1in horn-loaded dome tweeter with a neodymium slug magnet. Claimed resonant frequency is 1.6KHz, I measured two random samples as 1.4KHz - 1.45KHz. Not bad. The connection tabs are so ...

I put all four units through my DATS setup. Drivers are from Dave's stock & he's confirmed they're 'as received' (other than his sealing the cones) without any kind of pair-matching or other running. I've broken them in with varying LF sines to rated 1-way Xmax, and prior to testing they were run ...

Since I sometimes get drivers through here for testing, for the sake of interest, I thought I'd add a handful here when I get chance.

First up: my friend Dave has very kindly sent me a package of interesting units from his stock that he (rightly) thought I'd be interested in playing with. The 2 ...
