The Davis Acoustics Krypton 9 is a floor-standing speaker and the flagship model of the French manufacturer’s Krypton range. It combines advanced technologies with artisanal craftsmanship to deliver powerful, precise, and natural sound reproduction.
A Sophisticated Acoustic Configuration
At the heart of the Krypton 9 lies a three-way configuration featuring four carefully selected drivers:
A 28 mm soft dome fabric tweeter, specially designed to deliver refined and precise high frequencies up to 24 kHz.
A 130 mm midrange driver with a 7th-generation Kevlar cone, ensuring faithful and detailed reproduction of midrange frequencies.
Two 170 mm woofers equipped with treated cellulose pulp cones, mounted on rubber suspensions for deep and dynamic bass.
This configuration allows the Krypton 9 to cover an extended frequency range, from 35 Hz to 24 kHz, with an impressive efficiency of 93 dB.
Controlled Low-Frequency Reproduction
To ensure powerful and controlled low-frequency reproduction, the Krypton 9 employs two 170 mm woofers. These drivers feature a sophisticated design with treated cellulose pulp cones, oversized voice coils, and powerful magnetic systems. This setup delivers bass that is deep, dynamic, and precise, capable of reaching down to 35 Hz.
Kevlar for Superior Sound Precision
The use of a Kevlar midrange driver is one of the Krypton 9’s standout features. This material, renowned for its rigidity and lightness, minimizes distortion and enhances the driver’s responsiveness. The Kevlar cone is paired with a machined metal phase plug, optimizing sound dispersion and contributing to the exceptional clarity of vocals and instruments.
Optimized Bass-Reflex Design
The Krypton 9 utilizes a bass-reflex design with a carefully tuned front-firing laminar port. This design offers several advantages:
It enhances low-frequency extension, allowing the speaker to deliver rich and deep bass.
The front placement of the port makes it easier to position the speaker in a room, reducing constraints related to wall proximity.
The laminar shape of the port minimizes turbulence and airflow noise, preserving sound purity even at high volumes.
An Immersive and Realistic Soundstage
Thanks to its sophisticated acoustic configuration, the Krypton 9 excels in reproducing a wide and deep soundstage. Instruments are precisely positioned in space, creating a stable and realistic stereo image. This ability to recreate the ambiance of a concert hall or recording studio makes the Krypton 9 particularly appreciated by discerning music lovers.
Remarkable Musical Versatility
While designed to satisfy the most demanding audiophiles, the Krypton 9 demonstrates great musical versatility. Its neutral tonal balance and ability to capture the finest details make it suitable for all music genres, from classical to jazz, rock, or electronic music. This versatility makes it an ideal speaker for those who want to explore their music collection without compromising on sound quality.
Easy Integration into Hi-Fi Systems
Despite its high performance, the Krypton 9 is relatively easy to integrate into an existing hi-fi system. Its nominal impedance of 4-8 Ω and high sensitivity of 93 dB make it compatible with a wide range of amplifiers, including moderately powered models. However, to fully exploit its dynamic potential, it is recommended to pair it with high-quality electronics capable of delivering substantial current.
Enclosure: Medium-Density Fiberboard (MDF) construction

Frequently Asked Questions
What is the ideal room size for the Krypton 9?
+
The Krypton 9 is designed for rooms between 30 and 50 m². However, thanks to its front-firing bass-reflex port, it can adapt to slightly smaller spaces without compromising performance.
Is a very powerful amplifier necessary to drive the Krypton 9?
+
Thanks to its high sensitivity of 93 dB, the Krypton 9 can perform well with moderately powered amplifiers (starting from 50-60 watts). However, a more powerful amplifier (100-150 watts) will allow you to fully exploit its dynamic potential.
Is the Krypton 9 suitable for home theater use?
+
Although primarily designed for music listening, the Krypton 9 can integrate seamlessly into a high-end home theater system. Its ability to reproduce powerful sound effects and its precision in dialogues make it an excellent front speaker for demanding movie enthusiasts.
How can I optimize the placement of the Krypton 9 in a room?
+
It is recommended to leave at least 30 cm of space between the speakers and the rear and side walls. A spacing of 2.5 to 3 meters between the two speakers, with a slight toe-in towards the listening position, will provide an optimal stereo image.
Do the Krypton 9 speakers require a break-in period?
+
Like most high-end speakers, the Krypton 9 benefits from a break-in period. It is generally advised to play them for about 50 hours at moderate volume to reach their optimal performance.

I love them. And yet I really liked the JMR they replaced. I have fairly wide-ranging musical tastes and they really do the job well. I can confirm their reputation regarding the mids, they are indeed very appealing, very musical. The highs are very pleasant. I added an active subwoofer so I could have very controlled low-end foundation, but even without the subwoofer I would still have been won over.
The build quality is very good, the supplied metal bases have rubber pads at the rear and decoupling spikes at the front, and allow the floorstanding speakers to be tilted for better sound distribution in the room.

J'adore.
Et pourtant j'aimais beaucoup les JMR qu'elles ont remplacé.
J'ai des gouts musicaux assez étendus et elles font vraiment bien le job.
Je confirme leur réputation concernant les mediums, ils sont effectivement très séduisants, très musicaux. Les aigus sont très agréables.
J'ai ajouté un caisson de basse actif pour pouvoir avoir une assise très maitrisée mais même sans le caisson j'aurais été séduit quand même.
La qualité de fabrication est très bonne, les bases métalliques fournies ont des patins de caoutchouc a l’arrière et des pointes de découplage a l'avant et permettent d'incliner les colonnes pour une meilleure répartition du son dans la pièce.
I use them powered by Fosi V3 Mono power amps (one per speaker) driven by a Pioneer LX-505. I haven’t really played around with the bass yet, but the mids and highs are absolutely crystal clear, a real pleasure. A nice upgrade from my old Jamo S809. And the icing on the cake: everything is made in France, right down to the drivers.

Je les utilise alimenté par des amplis de puissance Fosi V3 Mono (un par colonne) piloté par un Pioneer LX-505.
Je n'ai pas encore trop joué avec les basses, mais les mediums et aigus sont d'une clarté absolu, un vrai plaisir, Un bel upgrade des mes anciennes Jamo S809.
Et cerise sur le gâteau, c'est tout su made in France, jusqu'aux hauts parleurs.
