We knew we could achieve more by investing all our focus and know-how to go beyond what’s already in the market. It’s still 13.8″. Looks about the same. But, it’s a different beast. The best we have ever made. With 50% higher excursion, better performance, and increased dynamics. The new 13.8″ world-class driver:
After thorough optimization and testing using FEA, Klippel, and other methods, we refined a motor featuring multiple aluminium shorting rings with a focused field “T” pole design. The result is a linear magnetic field over a long voice coil throw, with very low inductance. The latest version of this driver has been reworked and redesigned in every conceivable way, everything has been modified to squeeze out even more output, while not only maintaining but also improving the sound quality, not insignificantly compared to the initial 1723 driver.
Better magnetic field design with thicker aluminum shorting rings above and below the magnet gap, which improves control over inductance (and significantly reduces it) vs position and power – this significantly improves response and distortion over the older model. The symmetrical suspension consists of a heavily analyzed NBR surround and Connex spider with integrated tinsel leads. All combined to create a very high excursion with linear suspension. Again, this contributing to high output and a low-distortion, precise bass.
Our unique hybrid cone made of long fiber pulp and fiberglass, takes advantage of the pulp’s superior stiffness to weight ratio, with the additional rigidity of fiberglass to deliver a driver of massive durability that is inherently inert and self-damping. The result is a cone that achieves optimum pistonic motion at all frequencies it is required to produce and beyond, creating deep, controlled, and hard-hitting bass.
The airflow venting below the dust cap (venting holes in the cone body) and the spider (venting holes in the frame) have been added for two very important reasons:
The new Arendal Sound 1723 Subwoofers utilize an ultra-high temp polyimide former with an aluminum voice coil for low mass, high motor force, and optimum thermal dissipation. The benefit of using aluminum instead of copper in this format is that the weight is significantly reduced and heat exchange is substantially increased, while the conductivity decreases only slightly compared to copper. This means that a driver with less moving mass can handle more power without the voice coil burning up. In sum, this means a driver that can handle more power and that has a better transient response.
Why 13.8”? The 25% larger surface area, when compared to a 12” driver, yields a woofer that requires less excursion and power to achieve the same SPL levels. The result is lower distortion, higher power handling and most importantly – tighter bass. Every part for this driver has been custom tooled to deliver high output, low […]>
Every part of this driver has been thoroughly engineered, Klippel and FEA analysed and customized to deliver high output, low distortion, accurate bass. Designed to get the typical explosive, hard hitting dynamics, precision control and bass definition required to resolve the finest details of music that Arendal Sound is known for from the 1723 Series.>
“Revolutionary” is rarely used in the audio industry, especially for speakers and subwoofers. The new Avalanche 550 IQ subwoofer amplifier from Arendal Sound is one exception, measured in performance and technology. State of the art amplifier designed and developed from scratch to give performance and features you could only ask for at much higher price levels.>
Even for our 1961 series we opted with HDF (High Density Fiberboards) cabinets over conventional MDF (Medium Density Fiberboards). The reason being a much stiffer cabinet which improves dynamics and sound quality. Premium finishes, no vinyl. New designed puck design rubber feet with Arendal Sound logo engraved. 1961 is built on premium level.>
Quality bass starts with quality drivers. Our 5.5″ woofers are High Performing bass drivers which delivers at Premium level standard. Extreme dynamics is key for effortless and thrilling listening experience. Starting from single driver units to whopping quad drivers on the 1961 Tower!>
