post
The cabinet is constructed with a narrow baffle - not
only an aesthetically neat shape but also an advantage
in terms of sonics since you have a more stable baffle
which effectively muffles resonances in the cabinet.
The cabinet is made in 25mm MDF board, which has
good sonic qualities.
The cabinet is further strengthened with bars, which
in total yields a very stable construction.
We have chosen a silk-made soft dome tweeter which
provides superior transient response and a very flat
frequency response without
frequency response roll off is softer on a soft dome
compared to an aluminum.
After evaluating a large number of drivers from
different manufacturers we selected a driver which is
very competent.
For woofer/midrange we decided on a 6½" solid
coated driver which gives a smooth extended
frequency response with a controlled roll off.
The driver is made up of solid coated paper which has
good sound qualities, high strength and low weight.
The surface treated cone is extremely light but still
extremely stiff and effectively reduces resonances.
The rubber surround makes sure that no edge
resonances are present.
The moulded metal basket of "high flow" type that is
acoustically transparent and high precision since the
basket is shaped exactly due to moulding. This makes
sure that the basket is very stable and efficiently
reduces resonances. The basket is absolutely non-
magnetically, which contributes to a higher efficiency
of the driver.
A strong magnet combined with the light cone yields a
high efficiency and a good transient response.
We have chosen a -12 dB crossover that has a fast
transient response and a minimum of phase shifting.
The connectors are gold-plated and of bi-wiring type so
that you can connect to the amplifier with double cables
(bi-wiring), or connect to two amplifiers (bi-amping) for
further improving the sound. The following coupling
modes are available:
1. Upper terminal +
present) Default setting, the loudspeaker is fed with the
entire frequency range.
Without the loop between upper and lower terminal:
2. Upper terminal. The signal is only fed to the
tweeter.
3. Lower terminal. Now the signal is fed to the woofer
only.
