ScanSpeak’s unique AirCirc Magnet System -- named for the way it optimizes air flow within the chamber –- rearranges the traditional magnet structure from a single magnet to an open magnetic circuit comprised of six separate neodymium slugs. This, in combination with the chamber, results in the elimination of the reflections and resonances that compromise the performance of traditional motors.

The D3004-664000 gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.

Tekton Design Ulfberhts Tweeter Upgrade

Reviewed by lwin1949 on 08/11/2022

Replaced the stock Scanspeak tweeters with a pair of the Scanspeak beryllium dome D3004/66400 . The hardest part was keeping my soldering iron off the original tweeters magnets. They fit perfectly with the only difference being the additional mounting screw.
Sonically there was a big improvement in the sound quality. There was more micro detail, increased space around performers , more height in the soundstage and they provided an uncanny sense of realism. My only regret is that I didn’t do this sooner.

Just music

Reviewed by hbrew47 on 02/09/2014

Each speaker has two 26W/8861T woofers, two 12MU/8731T mid and one D3004/664000 Berillium tweeter. These integrate seamlessly. Madisound designed and built my crossover for these speakers. Fantastic set of drivers. Clear, dynamic and open. After 60 hours the speaker broke in with a sudden improvement in everything that I wasn't expecting.

I don't hear a tweeter just music. No harshness. What more can I ask for?

I haven't compared to ribbon types. I have a horn tweeter in another speaker and I am happy with both.

Best dome tweeter ever

Reviewed by benarritt on 01/16/2012

Crossed this over lower than the Scanspeak R2904 (currently at 2500 Hz but still playing with it). Seems to able to play lower than the R2904 without any sign of strain. Like the R2904 this contributes so much information to the midrange you simply don't hear in other tweeters...but the new D3004 gives you even more information than the R2904, opens the midrange up even more, goes lower with less strain AND improves on the highs (10,000 Hz +, cymbals etc.) The cymbals are now very holographic and it is the only tweeter I have heard I consider superior to the R2904. Holographic imagery almost comparable to a ribbon with the dynamics of a dome and a low cross over point. Amazing!
