I'm interested in this, too, probably worth an new (or different existing) thread. My gut feeling says that the impedance breaks arising from cutouts etc for the MF/LF drivers in the walls along the horn/WG expansion will disturb proper HF waveguiding quite a bit...

Between politics and nonsense, I'd choose politics. That is not as irritating.

Is there really a valid distinction between politics and nonsense?

In these forums this is a real problem. I for one am not about to go out and take data to prove a point that I make here - its just not going to happen. If I have data, then I will quote it, but I won't create it. These places are for fun, not work.

And this is what makes them so dangerous. Its easy to shut me up with a barage of posts, I'm simply not going to respond. What is the reader to conclude? - all too often the appearance is one of concession to the contrary points made, which need not be the case at all.

This leads to a tremendous propagation of misinformation by the shear weight of the posts and not by any science or relavance. It then becomes difficult to correct these misconceptions because the previous falty arguments are raised as "proof".

I'm not sure that the truth ever gets through on these long winded arguments.

Over on another post, I alluded to the idea that the voice coil will heat instantaneously and this could be what we hear as "dynamics" differences in tweeters. Then someone posted some very well done mathematical analysis of the situation and showed that this was unlikely to be an audible effect. End of discussion.

If the discussion goes on and on its usually because it is pointless and going nowhere.
Lots of your posts have inspired many ideas that I wish to explore. Just hope I get through with all of them.

Is there a way to organize the "Smilies" to personal preference of order?

HEAR, HEAR! No truer words spoken on any forum I've browsed/posted to IMO, so these two posts minus the OT tweeter comment ought to be added as a preamble to any contentious thread such as this one as a warning of sorts.

OT: Please provide the post link to the tweeter 'proof'.

TIA,

GM

Unfortunately not and its made worse by over half of them being pretty redundant. We have too many smilies here IMO.

In the future the forum software will see significant upgrades and maybe if we're lucky we'll lose some of the smilies.

Turn the forum into a blog, where the experts in the field will tell us all how it is, without fear of opposing opinions.
Much better that way - no room for free thought.

I would be glad to discuss this, I have before, but I won't do it in this tread. Please start one anew.

I always continue to learn. I just finished a book on General Relativity and am now reading one on Organic Chemistry. Its all my research that keeps me from answering posts that are not constructive.

I'm looking forward to the new software. I think this will be part of that. I prefer to approach things in a blog style manner because you can put all sorts of random rubbish into them and have it in one place. If someone is interested in what your doing then they look at that and it doesn't clutter up the forums.
