Our 1961 speakers are built around a 28mm synthetic soft dome with a custom designed, matching waveguide. This tweeter was designed for the 1723 series, and most of its design principles are transferred to the 1961 series. The soft dome itself is very lightweight, completely pistonic up to ultra-high frequencies, optimally damped, produced to exceedingly tight tolerances and specifically chosen for its sweet sound character and consistent frequency response. We basically utilize the same tweeter as in the 1723 series, but instead of a neodymium magnet assembly we opted for a less expensive ferrite magnet assembly that still makes the tweeter sound exquisite.The role of the waveguide is to take an already excellent tweeter and further refine its performance. The size and shape, although appearing to be rather simple, is in fact the result of painstaking modelling, testing and refinement. By precisely controlling the directivity over the entire frequency range of the tweeter, we are able to broaden top end dispersion that the tweeter naturally wants to beam straight ahead, and focus the frequencies at the lower end of the tweeter range that naturally want to spread out in all directions. This provides a more consistent polar response across the tweeter’s entire frequency range and a close match to the dispersion pattern of the mid-bass driver it is working with, simplifying the crossover design.
Everything about this tweeter except for the diaphragm has been completely modelled, designed and tooled from scratch. The motor of this tweeter is a powerhouse, all bespoke designs by Arendal Sound and extensive FEA modelling and optimization through Comsol. As usual we use Klippel analysis to review all driver designs.The end result is a high performance, high power handling tweeter with very good bandwidth, low distortion and high efficiency.
The waveguide was designed specifically for the new 1961 tweeter and its new speaker applications. It’s a constant directivity, custom designed and tooled waveguide in ABS plastic material, thick and sturdy to avoid any resonance.To give the waveguide assembly that final touch in feel and look, we designed and tooled an NBR rubber ring that fits smoothly to the end of the waveguide shape, covering screw holes and showing off a subtly integrated Arendal Sound logo.The waveguide serves several purposes, augmenting tweeter performance to a level that no flat baffle mounted single dome solution could reproduce:
The air chambers, venting and damping materials found behind the dome and surround are optimized to create a very well controlled impedance with no secondary resonance peaks, which typically cause electrical phase shifts that present an awkward load for amplifiers and further smear the sound, adding a harsh character.
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!>
