Speaker Toe-In; Spikes & Speaker Rake Angle - Wilson Benesch Precision Series User Manual

2.5 Speaker Toe-in

The amount of speaker toe-in will define a sharper centre image at the expense of image width. The upper frequencies will become
more pronounced as you bring the tweeters on axis with your ear at the listening position. While we generally recommend at least some
speaker toe-in, the amount is not a precise or fixed value. Experimenting here is advisable and evaluation at the listening position, while
an assistant makes toe-in adjustments, is one method to achieve the best balance.
2.6 Spikes & Speaker Rake Angle
The position of the tweeter has been designed to function best for listeners seated in conventional relaxed seating positions. However, the
rake angle of the speaker can be changed by adjusting the installed speaker spikes. Tilting the speaker back slightly will have the effect
of projecting the perceived sound stage a little higher. This can also change the perceived balance of the upper frequencies, as the tweeter
will be most prominent when it is on axis with your ear at the listening position. All the spikes in your Precision Series loudspeaker are
adjustable to allow you to alter the loudspeaker rake angle.
2.7 Loudspeaker Clearance and the Bass Port
Both P2.0 and P3.0 loudspeakers feature a bass port on the underside of its foot that is in close proximity to the floor. The low-frequency
augmentation of these two loudspeakers will behave in much the same way that it would should you place the loudspeakers next to
a wall. That is to say, adjustments in the overall clearance of the P2.0 and P3.0 from the floor will change the overall balance in the
system. Generally, it can be observed that a smaller clearance and closer placement to the floor will result in a more augmented low-
frequency characteristic to the loudspeaker presentation, where a larger clearance between the floor and the bass port will result in a less
augmented low-frequency characteristic to the presentation. This is a critical step in the loudspeaker setup procedure and in many cases,
the balance of the system will change considerably as this parameter is adjusted.
