JBL Aquarius IV (Type S109) _Floorstanding speakers

1970

Made in Los-Angeles, California

One of JBL’s most daring creations — the Aquarius series marked a turning point where hi-fi engineering met sculptural design. With its brutalist, avant-garde aesthetic, the Aquarius IV stands apart from anything else of its era.

Built around an omnidirectional concept, it disperses sound in 360°, creating a wide, immersive soundstage with no strict sweet spot — effortlessly filling the room. Despite its small footprint, it delivers a surprisingly full and spacious presentation.

Solid construction, high-quality JBL components, and a truly innovative acoustic approach make it a standout piece — as much for its iconic design as for its unique listening experience.
