That centre speaker looks very nice. Its hard to make out the actual finishes of the cabinets with the washed-ut photos, sorry.
Are the black curved speakers hollow?
Meaning is the whole thing the actual enclosure casing the drivers.

Haven't I seen these somewhere before?
A fascinating collection of alien-looking speakers. I think the 'rears' need to be mounted on barrel-shaped subs. They'd look like giant ants.
Which is your favourite speaker?

Favourites....
.. are "Windswept", the black curly things.
Hooked up to the HiFi system, (there is a pair of Dynaco MkIv's hiding behind them) they just do things "RIGHT!"
The pyramids are currently hooked up to the HT system.

Re: Favourites....
Windswept look fascinating. I like the idea of the dual lines and guessing about the internal construction, I think you've done it brilliantly. When I was designing my System IV which is a TL design, I considered having two or even four different lines. Having four drive units made this an obvious possibility. In the end, I settled for one line but I do wonder from time to time.
One of the things that Windswept do "RIGHT", according to your description is imaging. I find this very interesting.
Firstly, the 'baffle' is quite narrow. This is generally considered to be important.
Then the fact that the crossover is a series design must also help considerably. Phase problems in the crossover often seem to have a negative effect on imaging. I also suspect that the step in polar response as the woofer goes to tweeter doesn't always help.
The other things that you must have got right are internal resonances and vibration. These would both 'draw attention' to the cabinet and degrade the imaging. Could you comment on that?
What a shame we can't 'bottle' a speaker's sound and post it here for everyone to hear. Many of the designs that have been posted on the forum have such interesting 'personalities' that I would love to hear them.
Amazing tree BTW.
Please excuse my ignorance but what are the Dynaco MkIVs and are they wired up in the Windswept system?Andy Graddon said:

My Dynaco MkIv's
Dynacos were a kit tube amp from 'a while ago'.
They had a very good reputation.
My pair has been redesigned and includes such niceities as fully regulated power supplies etc etc, they push about 35-40wrms of pure, clean, smooth sound. Not loud, but REALLY sweet to listen to. 🙂

Re: Re: Favourites....
my thoughts (unproven) are that the method of construction has 2 very big benefits:..
1... there are no straight areas or parallel sides at all, even the front and back are not parallel
2... the gluelam method with alternative layers of glue and mdf seems to form a very non-resonant structure, you get different stresses and tensions throughout, so there is no single cabinet resonant point like flat regular surfaces can have. The "Tulips" have a similar un-coloured sound

Re: Re: Re: Favourites....
I think that you're right on both points. I have been reading lately that standing waves do occur with non-parallel sides but I believe that the problem is considerably ameliorated compared with parallel sides.Andy Graddon said:
