The A4-14 from Swedish Audio Pro is a truly unusual speaker.
It is a small three-way amplified with the bass section operating with the ACE-Bass corporate patent. this system allows, by means of two small woofers made on specific and an amplifier dedicated to them to obtain an extension of the linear response up to 30 Hz!
It was a revolution for the time (between the end of the 70s and the beginning of the 80s) where loudspeakers of the caliber of Klipshorn or Altec 19 stopped at 20 Hz higher than these, which quoted a volume 10 times lower.
Sonically it is a very balanced loudspeaker extended at the top and with a very natural medium range but the bass are incredible. The organ pedal seems to be reproduced by a quality sub-woofer
The pair for sale is very rare because it is the THIRD version, further refined and with standard RCA input instead of the very uncomfortable DIN
The woofers have just been refoamed and the electronics have been overhauled and are in perfect condition.
The multiple adjustments allow insertion in any type of environment. Just a streemer and you will have a complete system of absolute quality.
The aesthetic conditions are perfect, no imperfections worthy of note.
