Arendal Sound 1723 Subwoofer 1

In stock
Arendal Sound 1723 Subwoofer 1 has a rating of 4.96 stars based on 23 reviews.

The baby of our Subwoofers, the Subwoofer 1 is still a potent beast that would top many ranges. Using our proprietary 13.8” driver driven by our 500W RMS Avalanche DSP amp, the cabinet volume has been sized to produce an optimally damped system, producing low distortion, naturally deep bass. All of the features and technology that are present in our larger multi-driver subs are present, with no corners cut. Conceived as a natural match for smaller rooms, you will be amazed how large a room the Subwoofer 1 will be happy driving.

Engineering & Development

From the beginning, Arendal Sound products were developed with the mindset to recreate the original sonic event, with the highest level of accuracy. This requires a special consideration to balancing several factors: Dynamics, linearity, distortion, power handling, frequency response and Polar characteristics. Stress testing or accelerated life testing is a hallmark of all Arendal Sound designs. Each new design is required to pass a long list of difficult (if not insane) tests.

Lofty goals require custom parts and special attention to details at each step in the path to product realization. Each driver was specially developed from the ground up, requiring much expensive and special tooling. No off-the-shelf drivers were worthy of satisfying all of our goals. Over 2 years in development, following a painstaking progression from theory to reality - each driver is first modeled using advanced FEA (Finite Element Analysis) techniques to meet mechanical, electromagnetic and acoustic goals.

Premium Build Quality

Higher density and naturally better damped than MDF (Medium Density Fiberboard), using HDF (High Density Fiberboard) results in a sonically inert cabinet. Internal bracing has been strategically placed to increase overall cabinet strength and limit unwanted panel vibrations that may cause audible colorations.
We are especially proud of our new exclusive and fully custom made grills. For all Arendal Sound subwoofers we have made an elegant and simple metal grill, then wrapped it with a clean black cloth. All magnetically fastened.

We use no plastic parts.

Avalanche 500DSP amplifier

The brain of Arendal Sound subwoofers, the 500W RMS Avalanche 500DSP, are built around a Texas Instrument’s 48-bit data path (with 28-bit filter coefficients) DSP engine, allowing virtually unlimited design flexibility with the assurance of no signal degradation along the way. Each amplifier’s transfer function, power output limiting and thermal protection are monitored to the millisecond and are customized for each individual drive unit and cabinet combination. The high efficiency Class D amplifier modules are based on a proven topology that has been continuously refined over the past 4 years. Excelling in transient response, high current output and very low distortion, they deliver the necessities for highly accurate, deep bass with output capabilities that drives and controls each 13.8” woofer to its fullest potential.

13.8" woofer

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 distortion, accurate bass. Our unique hybrid cone 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 inherently inert and self damping. The result is a cone that achieves optimal pistonic motion at all frequencies it is asked to produce and beyond.

Enclosure tuning

All Arendal speakers start with an optimal, low Q sealed box designs. 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.


Luckily for you and for us, Arendal Sound products are extremely durable products which have gone through extreme stress tests during development. However failures may happen and if it does, you will always know we are backup you up. Arendal Sound have up to 10 Years warranty (5 for electronics) which cover all costs for you as a customer within the warranty terms.
