Default LCY 130 or SCAN-SPEAK Revelator?

Greetings!

I am considerind a LCY 130 ribbon tweeter but I am in doubt if the SCAN-SPEAK D2905/990000 Revelator wouldn't be a better option (more natural? better dispersion? easier integration with other drivers?)

Target: 3.5-way project with tweeter xo at 4KHz using a 2nd order passive crossover (tweeters to replace are the Beyma T2030).

Thanks for the help.

When crossing at 4 Khz, could also use a much smaller 19 mm dome, for better off axis response, like one of the Hiquphon OW's?

agreed about the millenium... owned both... compared both at the same time... no contest LCY 130 owned it

the SS is probably very similar to the Seas as far as what the LCY will do to it

Say more about the rest of the system, especially the midrange. I have the 9900 -and like it- but it is usually crossed lower to a relatively large driver. Directional control is the main advantage of the shallow waveguide on the 9900 which may, or may not, be appropriate for your situation. The idea is to match radiation patterns.

Yep, I like ribbons too!

Thanks for the tips!

Concerning the Hiquphon OW, I believe they're short on sensivity, which would have to be at least 90dB 1w@1m, to match the other components.

The midrange is a 2.5" soft dome with high dispersion (120). It is being crossed at 800/4000Hz, but I can cross it higher or lower, like at 3000 or 5000. You may check the full specs here:

http://profesional.beyma.com/ENGLISH...?pdf=MC115.pdf

Pianos and voices on this midrange are 3D and natural but it does not integrate well with the current tweeter, which I intend to change. Unfortunately, cannot hear the LCY or the SS 99000 before buying, therefore your opinion is so important.

Sony,
I have no experience with that mid, but dispersion appears to be quite broad...so, if it were my system, I would look really hard at 19mm domes.

Paul, I see you second 4real's opinion on the 19mm tweeter.
The Hiquphon OW models II and III seem to be a good option (from the site data) - if they had a better freq. response above 20KHz (for SACD) and a little more sensivity, the specs would be perfect.

Any other 19mm suggestions?

20k...your ears are much better than mine! Check out Mark K's pages for tweeter test results...several 19s there.

We cannot indeed hear waves above 20KHz, but those waves interact with the waves in the audible range changing the way they sound.

From the 'Mark K driver tests' I found out the OW got some not so brilliant results, after all.

I will continue searching for alternatives to the LCY 130.
