FINE TUNING
ROOM PLACEMENT
We recommend to place both speakers with the tweeter facing to
the inside.
Due to the controlled dispersion characteristics of the horns the
speaker will excite less unwanted reflections f rom the room walls
compared to conventional speakers. Thus they can be positioned
closely to back walls or corners (both or only one speaker in the
corner!).
Choose a position for the speakers (tweeter facing to the inside) in
your listening room. Both speakers and your listening seat should
form an approx. equilateral triangle. Ideally each side of the triangle
should be approx. 3,0m.
The speakers should be toed–in with the midrange horns pointing
directly to the listening position.

TOE–IN & TOE OUT
By facing the speakers inwards (toeing–in) or outwards (toeing–out)
you can further affect the focus and tonal balance of the system.
By toeing–out, the sound appears to be less "direct" or "forward
sounding", but may affect the focus of the centre image.
Toeing–in emphasizes increased focus on the centre image, but
may affect the width of the stereo image.
As the tweeter is located outside of the centre axis of the speaker,
toeing–in will increase its distance to the listener in relation to the
acoustical centre of the low & midrange horn. Toeing–out will
decrease its distance.
In order to compensate for this acoustical runtime differences the
tweeter needs to be moved forward when toeing–in and moved
backwards when toeing–out. The correct offset of the tweeter is
1 1
always 48,5 cm.

Choose your favorite toe–in or toe–out
position.

Take a cord and measure the distance
(xxx,x cm) f rom your listening position to
the centre tip of the big lowrange horn.
3
Take this length (xxx,x cm) and add
48,5 cm. This is the correct distance f rom
your listening position to the centre tip of
the tweeter horn.

Loosen the knurled knob
to release
the tweeter and move the tweeter
forward or backward respectively.
