All Arendal subwoofers start with optimally damped, low Q sealed box design. Low frequency performance is accurately damped delivering a tight impulse response – the time the driver takes to stop moving after the signal has passed is very short – and rolls off at the natural sealed box rate of 12dB/octave below the combined box and driver resonant frequency. This frequency (quoted as the -3dB point for the bass extension) is somewhat higher than a vented alignment, but the roll off below a vented subwoofers -3dB point happens at 24dB/octave. So the vented alignment does stretch deeper, but it rolls off sharper than the sealed box which may have a roll-off that is more in tune with your room gain.
As with Arendal speakers, but even more so because of the even lower frequencies involved, the sealed alignment naturally suits smaller rooms and positions closer to a wall. Room gain really kicks in hard below the rooms lowest resonant frequency, delivering 6-12dB of extra gain per octave below about 40Hz. This dovetails in nicely with the sealed alignment to give a surprisingly extended and naturally flat, in-room response and in the right room, will register output down into room shaking single figure Hertz!
Of course, many will be quick to realise that this extra lift can also add additional bass in rooms that don’t really need it, turning action movie sound tracks into a bombastic bass-fest! We deliver the choices, you use them to suit your taste without worry, because our sophisticated DSP has your back protected.
By removing the foam plug from the big slot port on our vented subwoofers, low frequency output can be extended with different bass character. Damping is slightly less optimal than the sealed alignment, but the compensation is sheer sound pressure level. Maximum extension is more or less the same as in sealed operation, but at all audible frequencies, there is a lot more output.
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!>
