New RAFALE VR1-X

New RAFALE VR1-X

Sept 2019
The ATOHM RAFALE VR1-X active subwoofer is the worthy successor of the celebrated V35, V38 and V38S models. It benefits from all the knowledge acquired by the company in the ongoing development of high performance compact loudspeakers and subwoofers.

 

The VR1-X incorporates the superb LD230 CRA 04 woofer. Endowed with the latest technical refinements, this unit redefines the expectations of what came be achieved from a driver unit of this diameter. Its specific alloy cone offers perfect rigidity and a wide bandwidth - even under the highest levels of mechanical strain. The surround and spider, each a result of extensive development and simulations, provide a very wide range of linear excursion as well as perfect dynamic stability (with perfectly symmetrical compliance). An impressive motorization of 156mm (Technology FWI technology : force without inductance) confers a remarkable level of sensitivity for a "subwoofer" driver application. The S250 amplifier module propels this exceptional driver with up to +/- 20mm of excursion. Its class D power stage offers an ideal damping factor. X-GUARD (active excursion control) technology limits distortion as well as maximum excursion when required by an inappropriate level. U-GUARD technology provides "soft" clipping by reducing the creation of harmonics. The bass reflex system features a wide port whose floor is the extension tuned at the lowest frequency. The layout and geometry of this vent have been optimized to allow strong amplitudes while minimizing port noise. The cabinet is crafted of MDF and the weight of the complete assembly renders this subwoofer perfectly stable. The 4 feet are equipped with EPDM high damping foam to significantly reduce the transmission of vibrations, thus contributing to the extreme precision of the sound.

 

The size of the VR1-X remains similar to many sealed subwoofer models. However, with it exceptional driver and its optimized vented load, the VR1-X is distinguished by a nice extension in the bass, very low rate of distortion in its bandwidth and breathtaking dynamic capabilities (111 dB rms @ 1M ). At listening, the timbres are both accurate and faithful. The VR1-X surprises by the density and the dynamics it provides without "coloring" the system it completes. Superb and in either stereo or home cinema applications, it perfectly integrates into any system based on bookshelf or medium sized floorstanding speakers.

GT-SW2 subwoofer becomes  " HD"

GT-SW2 subwoofer becomes " HD"

July 2019

Following the release of the new LD230 CRA "Absolute Series" units, the GT-SW2 subwoofer is evolving to become "HD". If the cabinet, rather massive, remains the same, this new version is now equipped with 2 units LD230CRA08M specifically optimized for closed applications of low volume (22l here!) In order to benefit from the additional excursion provided (+/- 19mm) by this fabulous tandem of driver units, the "X GUARD" circuit (active excursion control) of the S500 module is modified accordingly. The GT-SW2 -HD therefore provides a greater SPL MAX between 20 and 35 Hz with a significant decrease in distortion.

What better to accompany our famous GT1 or their sisters GT2 and GT3 (or any other high-end speakers).

LD 230 CRA  : an “ATOHM ‘s concentrate” !

 

The suspension  with its LDS profile and the spider with its progressive geometry have undergone extensive studies and many computer simulations ( finite elements method) in order to guarantee a wide range of linear excursion .

The spider features a special material chosen for its very low level of creeping and offers a steady stiffness coefficient on its nominal excursion. As for the suspension, not only does it feature a virtually perfect linearity during maximum excursion, but it also keeps a perfect geometry under the strongest mechanical strains. ( for example : low volume closed enclosure  or physical pressure at the  tuned frequency of a bass reflex speaker  ) In order to limit “dynamic DC shifts, these 2 components are acting in a totally symmetric way. The cone , made up in a specific alloy , has also been optimized in order to guarantee perfect rigidity  on a very large frequency range and under the strongest mechanical strains.

The imposing size of the Motor ( 156mm diameter) benefits from the  FWI (Force without Inductance) technology. Skillfully sized, the polar parts and the copper ring allow for great reduction and linearization of the inductance value. Depending on the driver units, the voice coils are fabricated with copper wire or with copper clad aluminum wire ( CCAW ) . There as well, the system is optimized to provide a force factor which is linear and symmetrical on the broadest range possible of power and excursion. In order to reduce drastically functioning noises, under high amplitudes and to improve cooling, the frame , made up of injected aluminum, and the cone have  large openings for ventilation.

"PIANO WENGNUT"  FINISH

"PIANO WENGNUT" FINISH

Mai 2018
" PIANO WENGNUT " new finish for "GT SERIES" loudspeakers

Contraction of "Wenge" and "Walnut" words ,  this new finish is made of  true french walnut wood veneer with wenge taint and with  high end "piano" lacquer coating.  

This new color will fit perfectly in modern interiors as well as classic or old style habitation . 

From now on, all GT SERIES loudspeakers are coming without any visible  cover's magnets on their front side .  The fabric frame is now maintained by  encapsulated magnets .  This offers a more "minimalist" aesthetics when regular fabric frame are removed and especially when the "round fabric cover"  (provided together with the loudspeakers)  are using to protect drivers units .

 

Availability  :

GT1-HD : in stock

GT2-HD, GT3-HD and GT-CENTER :  scheduled on early of July

The GT2-HD floorstanding speakers rewarded "Meilleur Achat" by the french magasine Haute Fidélité n°216 April/May 2016

 « Rarement la transparence d'une paire d'enceintes aura été si bien optimisée, dans cette gamme de prix particulièrement disputée. L'habile conception, mettant en œuvre des transducteurs étudiés dans leurs moindres aspects, de manière à obtenir les meilleurs performances possibles, constitue une réussite totale, sur les plans de l'esthétique, l'application de techniques très pertinentes et du relief musical que nous ne sommes pas parvenus à mettre en difficulté. Ces colonnes sont donc intéressantes à plus d'un titre, tant pour la pléthore de solutions techniques originales, que pour leur excellent rapport qualité/prix... »
