THE HECO AMBIENT 11 F, 22 F AND 44 F IN STEREO MODE
In the ideal configuration the speakers and the listening position should form an equilateral triangle.
When the left and right speakers are the same distance from the listening position their sound
arrives at the same time, resulting in a harmonious, natural music reproduction. (fig. 3)
There should be a clear line of sight between the loudspeakers and the listening position.
Any sound-absorbing or reflecting obstacles in the path will distort the sound.
The HECO Ambient loudspeakers are ideal for use with the Ambient Sub 88 F active subwoofer.
Fig. 9 shows a method of connection. Please also refer to the subwoofer’s and your amplifier’s
operating instructions.
THE HECO AMBIENT 11 F, 22 F AND 44 F IN HOME CINEMA MODE
The front speakers are placed on the left and right at the same distance from the TV as far as
possible, and at ear level. The 22F and 44F models, mounted vertically, are best suited as front
speakers. (fig. 4)
The centre speaker is hung in the middle, below or above the TV. The 44F model is best suited as a
centre speaker. It should be fitted horizontally.
The rear speakers are placed on the left and right next to or, preferably, behind the listening position
at ear level or slightly higher. The 11F and 22F models are best suited as rear speakers.
In the AV receiver setup, the crossover frequency of the front and rear channels should be set to
approx. 80 Hz, if possible.
The recommendations in the previous chapter otherwise apply.
AUTOMATIC CALIBRATION
A lot of modern AV amplifiers and receivers provide the option of automatic system calibration
via microphone. Calibration is advisable as the levels and distances of all the loudspeakers are
determined automatically and, depending on the calibration system, the frequency responses
of the connected speakers are also corrected in order to compensate for poor room acoustics.
Please read the user guide for your AV amplifier or receiver in this regard.
THE HECO AMBIENT SUB 88 F SUBWOOFER
The Ambient Sub 88 F active subwoofer visually and acoustically ideally matches the other
loudspeakers in the Ambient series. Please refer to the separate operating instructions supplied
with this product.
CONNECTING TO AN AV RECEIVER

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All HECO loudspeakers are designed and built for optimum sound reproduction with the tone
controls in the central position – i.e. with “linear” amplifier output. Turning up the bass and treble
controls too far delivers more power to the woofers and/or tweeters, and at high volumes this can
actually destroy the speaker units!
If the output of your amplifier is significantly higher than the rated power handling capacity of your
speakers extremely high volumes can physically destroy your speakers. This doesn’t actually
happen often but you should be aware that it is possible.
