Tweeter
The Scan Speak D2904 9900 Revelator Silk dome
tweeter is a 28 mm silk tweeter that has a wide
dispersion an excellent detail. This tweeter, coming from
the Revelator series, provides the breath and depth a
high end loudspeaker need.
The Bass Reflex Vent
The flared vent is located on the front-baffle of the
loudspeaker. This means the speaker can be set-up
relatively close to the backwall. Also, mid-frequencies
that are radiated through the port are not all messed up
on the back of the speaker. This setup enhances clarity
and transparency. The vent, in combination with carefully
adjusted internal damping of the speaker, provides real
low energy output, without the typical booming bass so
often associated with vented enclosures.
The Cross Over
Designed for optimal integration between low-mid-and
high frequency response, the Pure is equipped with a
custom built series cross over. The cross over frequency
(-3 dB point) is @ 2.3 kHz. The whole crossover range is
within +/- 1 dB. The cross over uses only high quality
components. Mundorf Supreme and MKP Capacitors,
non-inductive metal oxide resistors, and matched Tritec
air core inductors and Mundorf low Rdc transformer core
coils with vacuum impregnation are all hard wired with
silver solder for undistorted signal processing.
Internal Wiring
Internal wiring was done with High Current OFC copper
cable for low, OFC speaker cable for mids and Teflon
insulated Silver plated OFC cable for highs. All
connections to the terminals and the speakers
themselves were soldered with Silver solder to ensure
long lasting performance without degradation
Connections
The Pure is fitted with gold plated 5-way binding posts
suited for single wiring. Due to the use of a series cross-
over, bi-wiring is no option.
Speaker Placement
The Pure is capable of presenting a stunningly true 3-D
image of the musical information. As a result of the very
good dispersion properties of the loudspeaker, and the
cross-over topology, imaging is very real, and music is
perfectly integrated in the soundstage. This effect is most
optimal when the loudspeaker is placed in the freely in
the room. However, the speaker is designed to perform
well when placed in the proximity of (back) walls.
However we advise you to keep the Pure away from
corners, as this wil ruin the imaging and tightness of the
sound. In that case you could have bought a low class
loudspeaker. We advise to place the speakers like the
