Pair of French 3A servo-controlled loudspeakers, model Master control 680. Controlled, adjusted and recaptured after changing the bass driver which is a Focal 10NS511 instead of the original 3AW150. Replacement of the capacitors by Panasonic whose quality is recognized. Connection like a classic loudspeaker with the loudspeaker cables output amplifier; the control is done on the bass driver with the addition of an internal 125W amplifier to correct its displacement. The result is surprising by the depth of the bass for such a low volume loudspeaker; the listening tests compared it to its big sister, the 3A ARIOSO which is equipped with a 38 cm bass driver .... Pair of unbalanced loudspeakers, one right, one left as shown by the positioning of the other tweeter and midrange. Note the band tweeter specific to this model. Adjustment on the back depending on the positioning of the speaker, on the floor, raised etc .... Find all the characteristics and tests on the 3A website: type 3A andante 680. Speakers of small volume, but with a unit weight of 22 kg each .... can be sent by Mondial Relay to be agreed, removal on the spot and listening recommended.
