Way. WAY too much time on his hands 😀.
Great work. But, Ant, as you've got all that time, could you come round and mow my lawn, wash my car, do my job for me etc. etc. so that I've got some time to make speakers? 😉

HEY! What's going on?? Those look real. 🙂
Very nice. I'm not crazy about the black p-lam, but overall very cool design.

Unfinished curvy LGT? Not very difficult at all to build this.

I can't see the similarity other than a gloss finish. Do they have a new design?
Personally I think this has more in common:

If I coloured them yellow you'd never know the difference! 😀

And so they shall be dubbed 'The Marmite'. Think outside the box. 😉
I don't need to build speakers any more, all I do design in CAD. Its far quicker and easier. Sure they don't make much music but I think that's overrated anyway. 🙂
Hi Shin. Not to change the subject but what made you chose Raal tweeter over other tweeter. At the price that Raal sell, there are other high end tweeters available. I would think that a silk dome gives you a better of axis response in this particular case. So, I guess the question is, what are the benefits and drawbacks for this particular arrangement? Could you elaborate on it if you have time?
Thanks.
Thanks.

A few obnoxiously insistent people proclaiming some nonsense about true ribbons (especially really good ones) having some sort of magical quality. I believe one fool in particular suggest that other normal tweeters sound broken in comparison. 😉

Initially I wasn't at all sure about RAAL. Nobody had one that I could demo, there was scant measured data except for that provided by RAAL, it was relatively expensive and I had a few others earmarked on my shortlist at the time. I took a chance really.
As you highlight, vertical off axis performance is the weak spot. Horizontal is better than a 1" dome and slightly better than 3/4" dome too. This, in my mind, can be seen as advantageous because it avoids a good proportion of floor and ceiling reflections, others would disagree. Having said that, its not the sort of tweeter where you can stand up and not notice a tonal shift. But sit on the vertical axis +/-15 degrees and all is well. The horizontal sweet spot is huge so no concern there.
The sound quality of these tweeters shames anything I've heard so far. Its tough to listen to domes, even the good ones. They just don't sound as dynamic or as close to reality. The difference is surprising.
Its very addictive and you can hunt and hunt for a driver that suits so once you find a manufacturer that meets the needs then its probably wise to stick with them. To this end and rather than mess around building new speakers, I'll be overhauling the LGT with custom mids and tweeters. The mids are AT ones but with greatly improved sensitivity and some other tricks. That's not the interesting part though. The new tweeters will once again be RAAL and this time with improvements borrowed from what's currently going into the new high end "Pro" line but in form factor that slots right into the LGT. Alex will be incorporating a 25mm x 140mm ribbon element into the design with some very powerful neo magnets to achieve over 1Tesla across the entire gap. Very sensitive at 102dB and early indication show this will have low distortion and compression, especially at high SPL's ie. 120dB. Once finished I have no doubt this will be the finest tweeter I've used yet.
That's what owning and listening to RAAL does. You don't ask which tweeter shall I upgrade to but instead you simply go back and ask Alex to come up with something that fits your new requirements.
Ant -
Romy the Cat at Good Sound Club searched for high efficiency tweeters, and he ended up with another of RAAL:s designs, the Water Drop. It has even more than 102dB/W but has a more limited freq range than the RAAL you are using. The Water Drop is a custom job and is not listed on RAAL's web site.
You might fins some very interesting discussions about this tweeter and how to integrate it into another driver at Romy's site.
Here's the beatiful ribbon tweeter:
