Last year I made a pair of minis for the ScanSpeak exhibition at the
Munich HighEnd show. These minis featured the prototypes of this
D3004/604010 beryllium dome tweeter. Here one year later, ScanSpeak has
finally launched the tweeter with a slightly modified grille
incorporating a small phase plate in front of the dome, presumably
smoothing the 15-20 kHz range.
Now, these tweeters sell at 318 EUR/each incl. VAT compared to 444 EUR
for the D3004/664000 and 475 EUR for the D2908/714000. Hmm... quite some
money to be saved. For comparison, check out my tests of the 6640 and
7140 Be domes
To cut a long story short, I can't wait to incorporate these domes in the Illuminator-5 and AudioTechnology 3-Way Classic. Based on the measurements below, I would be very surprised if they don't perform as well as their more expensive siblings.
The domes feature a metal face plate, or should we say mounting ring.
All-metal non-resonant rear chamber. Only thing to take care of is the
soldering tags. These are for good reason mounted on plastic sockets and just
don't add too much heat from your solder iron.
Download specs here.
As mentioned above, the terminal are stuck into a plastic socket and if you like me use the tweeters for multible applications, secure the terminal sockets with some Araldite. Use a syringe with a large needle, cut the needle to 1 cm and inject glue below the terminals as seen on photo. Still, solder fast and with as little heat as possible.
