  • Hi-fi elegant: Slim front runner of the Quantum 750 range:
  • 25 mm fmax fabric tweeter with extended frequency range
  • Distortion-optimized 170 mm ceramic-aluminium cone woofer for particularly precise voice reproduction

Floor-standing loudspeaker, 3-way bass reflex with double bass


The Quantum 757 is the remarkably slim front-runner of the Quantum 750 range. It provides, in addition to the extremely low resonance. Besides the extremely low-resonance 45 mm case front on a corpus with multiple stiffening, it offers a clear and modern language of shape that is available in perfect high-gloss or silk-matt varnish finishes. The latest-generation computer-optimised loudspeaker chassis deliver an uncompromisingly clean and dynamic sound.


The Quantum 757 is available in a black, white and black-mocha finish. Two bass loudspeakers and one bass/mid-range loudspeaker with a diameter of 170 mm in conjunction with a ceramic-aluminium cone in a high-strength die-cast basket are responsible for highly precise sound and clean transitions to the powerful "F-Max" fabric dome tweeter with dual-compound cone. The offset high-gloss base is responsible for a stable stand and a perfect look.

Test reviews

What do trade magazines say about this product?

Absorbers or metal spikes - you decide!

All floor-standing speakers in the range can be set up with the support of resonance absorbers or, alternatively, metal spikes supplied additionally.

Gold-plated bi-wiring terminal

The loudspeaker cables are connected to the terminal with encapsulated clamps, providing secure contact even for larger gauge cables. Bi-amping and bi-wiring are also possible.

Bass/mid-range drivers in detail

The baskets of the 170 mm bass/mid-range drivers are made of torsion-resistant die-cast aluminium. Together with the aluminium-ceramic membranes, these chassis guarantee particularly high impulse fidelity and clean bass reproduction.

The noble art of precision

A high-efficiency Magnat Fmax tweeter consisting of a dual-compound fabric membrane operates in the treble range. A dampened pole piece hole produces a particularly harmonious transition to the mid-tone range.

Customer evaluation for "Standlautsprecher, 3-Wege Bassreflex mit Doppelbass"
(0) 4 Feb 2022

Für meinen 24 qm Meter Hörraum absolut top!

Seit etwa fünf Jahren beschallen diese tollen Lautsprecher mein Wohnzimmer. Die klangliche Bandbreite ist hervorragend, mit klaren Höhen, mehr als ausreichend Bass und insgesamt sehr ausgewogen. Würde ich jederzeit wieder kaufen. Vor allem zum aktuellen Sonderpreis.
