tHE ACtIVE SUBWOOFEr HECO ALEVA gt SUB 322A
This subwoofer has been adapted to provide the best visual and acoustic match to the heCO AlevA GT
range of loudspeakers. however, it goes without saying that it may be combined with other loudspeakers.
POSItIOnIng
The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That‘s why
positioning generally doesn‘t present any problems. however, it is preferable to place the speaker close
to the front loudspeaker in front of the listening position. You should also make sure that the distance from
the sides and from the rear to items and walls is at least 20 centimetres as otherwise bass reproduction
may be impaired.
