Frequency Response:

38Hz-30Khz +/- 3 db

Impedance:

8 Ohms nominal @ 1000 kHz- Very easy load on any amplifier including low powered tube amps. See Impedance & fantastic phase curves below

Sensitivity:

88 db (1 Watt, 2.83 V @ 1 Meter)

Bass/Midrange Driver:

7" Carbon Graphite Fiber/Paper Pulp composite cone with non-resonant low loss butyl rubber surround & Kapton voice coil former & die cast frame with massive magnet, bass reflex loaded- rear port.

This unit is an improved version of the highly praised 18W/8545-00 midwoofer, where a new aluminum chassis, an updated cone and a new spider as well as a few other details are introduced, these updates improves mechanical stability and sound performance.

High-quality magnet system design with patented Symmetric Drive (SD-1) continues to be a key feature. The magnet system is the new SD-1 system which eliminates modulation and dynamic distortion, as well as clipping distortion created as it exceeds its maximum linear excursion.

Tweeter:

ScanSpeak AirCirc or Illuminator Tweeter

1" Textile Dome Diaphragm
Magnet System w. Alu Ring
Large Roll Surround for Wide Dispersion
AirCirc Motor Design w. 6 Neo magnets
Die Cast Rubber Painted Alu Face Plate

The AirCirc and Illuminator tweeters continue on with the heritage of the renowned Revelator D29. The large-roll surround and textile dome diaphragm provide a flat frequency response to above 30KHz with outstanding off-axis dispersion. The face plates are die cast in aluminum for a beautiful look with maximum mechanical stability. Scan-speak’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 tweeters gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.
