The amplitude response of the Scan-Speak D3004 / 660000 Illuminator is extremely broadband. Full level already from 600 Hertz.

From 600Hz - 30kHz + -1,5dB linear with a broadband peak (+ 2dB) from 1,5kHz - 6kHz. The average efficiency is 92dB / 2,83V.

The omnidirectional behavior is very good. Under 30 ° 20kHz are reached with practically full level. The resonance frequency is extremely low with 470Hz and gives hope for a very low separability to the TMT / MT. The 1,5kHz impedance response shows a minimal disturbance, which is also reflected in the amplitude response by a harmonic "level".

Graph switches every 3 seconds
The Scan-Speak D3004 / 660000 Illuminator has extremely low harmonic distortion.

K3 remains below 500% at all measured levels already starting at 0,3 Herz, from 1kHz <0,1% and runs largely independent of the excitation signal.

K2 increases evenly with the level, and runs at a very low level.

Clinker components of higher order are negligible.

Summary


The Scan-Speak D3004 / 660000 Illuminator is an outstanding tweeter in the sum of its features. Very broadband use, extremely low distortion and with very good omnidirectional behavior.

There was a considerable design effort to create an extraordinary tweeter. The Air-Circ Magnet System (6 Circular Neodymium Magnets) seems to work very effectively.

Only the not absolutely linear amplitude response on the axis clouds the otherwise impeccable impression minimal. By skillful wiring and / or selection of the baffle can still achieve a virtually perfectly linear frequency response.

Also noteworthy is the noble-looking exterior of the tweeter. The aluminum front panel and the seemingly futuristic magnet system make your heart beat faster, and in the sense of psychoacoustics, the driver will probably (even) sound even better ())

In order to meet the stated price of UVP 180 €, there are features that set the driver apart from others. In my opinion, these are certainly given with the Scan-Speak D3004 / 660000 Illuminator and the driver is probably his Price-worthy!

  1. As a final note, the text of the Scan Speak tweeter on the Waveguide did not work that well. What were the rough results or problems? Best regards, Ralf

    1. Hello Ralf

      The amplitude response looked very good, but there was a leak somewhere due to the mounting of the adapter plate, which I have not come up with. This can be seen on a BR-like impedance gear.

      Best Regards
      Alexander
