Shelf loudspeaker, 2 way bass reflex

A compact housing in combination with above-average acoustic performance. Technological excellence and innovative design come together in this exceptional compact loudspeaker to create an acoustic masterpiece – a real gem!
The front of the high-gloss varnished MDF body is adorned by a solid aluminium front panel with milled and burnished sound guide for the low-midrange loudspeaker and tweeter. The double base plate is also made of solid aluminium and has been combined with polished acrylic glass. Only high-quality components have been used for this two-way bass reflex system whereby the emphasis was placed on selected drivers (110 mm low-midrange loudspeaker, 25 mm dome tweeter and the also very high-quality cabling with particularly large cross-sections.)

What do trade magazines say about this product?

Plus X Award 2014

„High Quality / Design“

sempre-audio.at 07/2014

„Particularly elegant design, top-class finish, high-quality materials, very dynamic, richly detailed reproduction, sometimes even analytical performance and full bass range despite its compact dimensions.“

i-fidelity.net

07 / 2014

„The Quantum Edelstein is a hot candidate for the pole position within the shelf speaker class up to € 700 per pair. Visually impressive and sound on the level of the best, the speaker is perfectly suited for anyone with high demands in terms of design, those who strive for the smallest dimensions and anyone who does not accept any acoustic compromise.“

HiFiTest

01/2014 (Set)

„The small Quantum Edelstein speakers proved to be the surprise package in our test, as they deliver a wonderfully vivid sound pattern despite their small size; the only thing lacking is a slight degree of emphasis in the bass range.“

„Small, desirable and elegant - a real gem, the latest addition to Magnat´s Quantum series has clearly been designed for the modern environment - these are small and chic speakers thatdeliver a strong-sounding performance and speakers that the "lady of the house" would be proud to show off to visitors. The price set for the Quantum Edelstein“

Reduced design – acoustically to the point

You won´t find any extravagance, decorative elements or embellishments here! Instead, the Edelstein is convincing with simple elegance, high-quality craftsmanship and a touch of noblesse.

Stylish aluminium front for optimum acoustics

The targeted mechanical coupling of the silk dome tweeter to the solid aluminium front panel ensures optimum dispersion characteristics with low inherent vibrations.

Perfect looks even from behind

The milled aluminium connecting terminal with gold-plated, totally insulated screw terminals also allows the use of larger-gauge cables.

Perfect acoustic decoupling

The silk dome of the tweeter is perfectly balanced acoustically. The especially wide surround offers optimum dispersion characteristics in combination with the special sound guide in the aluminium front panel.
