The Balthus 90 is the largest floor-standing speaker in the range. Slightly wider than its two smaller siblings, it houses two 21 cm diameter woofers, allowing it to reach deep into the low frequencies. With impressive bass capabilities, it can effortlessly fill a large living room without the need for a separate subwoofer. The bass is firm, well-defined, and does not linger, provided it is powered by a good amplifier. The “magical” mid-high range, identical to the other models in the range, completes this floor-standing speaker. With an incredibly wide frequency response, the BALTHUS 90 immerses the listener in the heart of the music without any sense of frustration.

From the organ to the cymbals, every instrument in a symphony orchestra is present with equal energy, resulting in a pleasurable sense of realism.

If possible, it is recommended to pair the Balthus 90 with amplifiers ranging from 100 to 200 W per channel. This model is suitable for larger living rooms ranging from 25 to 50 m2.

The opinion of specialists

On Mag, le test

"A great achievement by this French manufacturer who offers a range of affordable speakers that are well-balanced and consistent. Its three models are intended for different uses, especially different listening spaces, but the key point is that the midrange/treble remains consistent across the Balthus 50 and 70. It has managed to make us experience music with an almost instinctive joy and a richness of sound that illuminates all recordings."

"From my point of view, the Balthus range from Davis Acoustics presents clear advantages for our customers. It allows many audiophiles to enter the world of high fidelity with ease because they are easy to pair, well-crafted, affordable, and, above all, musical. Customer feedback is always positive, and since their arrival, they have quickly established themselves as best-sellers in their price category. Furthermore, the Balthus speakers fully align with the philosophy of Quai du Son: offering sound quality at accessible prices."
