One on his replies was his Adams monitor speakers.

This seems to be a German company and the only thing I
can see is that they don't have grilles at the front
(so how do you keep the dust out ?). They seem to have
an unusual tweeter, not the usual cone arrangement.

Other than that, what is the difference between one
and a 'normal' speaker.

This one is quite extensive.

I have just looked at the Thomann website. They seem to have the whole range. Yes they are expensive.

I had the opportunity to do some tests on one of Oskar's gadgets in the late 1980s. I used 4 cycle tone bursts and picked up the output with an AKG CK2 omni condenser mic and viewed it on a scope. Of course, I simply listened to sine waves at various frequencies too.

The strange contraption produced obvious, spurious outputs that were not part of the input. Harmonic and non harmonics of the input sine frequency as well as extra cycles and even whole bursts at frequencies above 10kHz.

IME most dome tweeters perform as well or better, good ones much better.

The tweeter part of a Quad ESL57 eats it for breakfast - I owned a pair at the time.

In a word "harsh".

Very.

Yes, I tend to feel listening to modern speakers that my tannoys tweeters
have some excitable upper harmonics, probably due to the horn bit.
However cheap speakers do not have to sound crappy, and neither do
expensive ones. There were a few months ago at least some with the strange
name of Beng, which sound pretty good at normal domestic levels to me. OK
they are not going to be used in a studio but for 70 quid, I mean they are
better than most bundled middi stereo ones.

Some weeks ago, before the JBL L100s were mentioned here, I had the opportunity to borrow a pristine pair with a view to purchase. One still seems them in some quite salubrious places, and a colleague of mine has a pair, so I thought I would give them a try.

They are indeed "bright" but for 60s/70s jazz they take some beating. This pair is perfect except that the front grilles have seen better days. I got new grilles made, and stuck cardboard discs, about the size of a Euro coin, inside the grille, in front of the tweeter and mid range unit. This attenuates the brightness. I very much like the detail and good stereo staging.

Tonight, I listened to the Buddy Rich album "Big Swing Face" on them. It's an album I know well. I enjoyed it immensely.
