Page 4: Installation
INSTALLATION Carefully remove the loudspeakers from their packaging boxes on the floor, on a soft surface such as a carpet. · connecting the loudspeaker leads Connections are on the base of the speaker. Connect the speaker cables before assembling the top part. Turn the speaker body gently to the floor (“Woofers are on this side”... - Page 5 The farther from the speakers the listener goes, the more room colourations will be added to the sound. Thanks to Gradient Revolution's directivity properties it can be listened to at much longer distance without loosing the accuracy and spectral balance.
- Page 6 CORRECT PHASING The bottom and top part of the speaker can be installed in three different ways with respect to each other. In order to guarantee the correct phasing to the listening area it is important to note that the plug of the top part is in a correct position.
- Page 7 USE AS A PANEL SPEAKER The Gradient Revolution speakers can be positioned in a free space as any panel speakers. In this case it is recommendable that the distance from the rear wall will be minimum one meter (3'). In theory increasing the distance from the rear wall will allow the speaker to go lower in frequency.
- Page 8 “Woofers are on this side” text). Try different distances (1 m...2m) from the rear wall and turn the speakers. In a narrow room Gradient Revolution loudspeakers can be positioned quite near the side walls. The recommended minimum distance is about 50cm (20'').
- Page 9 AGAINST THE WALL The Gradient Revolution has an unique feature for a panel speaker: it can also be positioned against the wall. The longer wall of the room is preferable. When used against the wall the woofers are directed towards the side wall as in the Fig. 3. In this case “Woofers are on this side”...

- Page 11 THE MIXED POSITIONING The Gradient Revolution speakers can also be positioned in such a way that one speaker is against and another will of the wall (Fig. 5). Please check that the plugs of the top parts are correctly positioned.

Page 12: Connections To The Amplifier
CONNECTIONS TO THE AMPLIFIER Gradient Revolution is equipped with two pairs of binding posts which are located on the base of the speaker. The red marked plus terminals are linked together by a jumper. The black marked minus terminals are connected in the same way. The speaker can be connected single-wired, bi-wired or bi-amped. - Page 13 CONNECTIONS TO THE AMPLIFIER · bi-amping In this case the speakers are driven by two amplifiers. One amplifier drives the bass part and another the midrange & treble part of the speakers. Disconnect the jumpers between binding posts (both channels similarly). Connect the leads from the bass amplifier to the upper binding posts.
- Page 14 It is recommended to use an amplifier of 2 x 50W ... 250W / 8 ohms with Gradient Revolution. Also higher powered amplifiers can be used with caution due to their increased potential for speaker damage.

Page 15: Power Handling
Gradient Revolution loudspeakers can handle high powered peaks of short duration. Music of varying dynamics (even huge) can be listened to at a high volume level. - Page 16 The woofer section of the Gradient Revolution can be rotated and directed in three different ways, to minimize undesirable standing waves in the listening area. This ability to "tune"...
- Page 17 A BRIEF DESCRIPTION OF TECHNOLOGIES Thanks to the cardioid radiation patter the speaker radiates frequencies over 200Hz mainly to the forward direction. The backward radiation is dampened most effectively being in power only one percentage of the forward radiation. Unwanted reflections from the nearby boundaries will be minimized and the midrange will sound clean without colourations.
