The end goal of most audio enthusiasts is to accurately reproduce the sound and feeling of an intimate concert venue with great acoustics, however due to limitations on size, space, and volume levels this is not always achievable. If you break down the sensation of live music, acoustically at least (not discounting the emotional experience that is live music), there are three concepts necessary to reproduce a performance such as this: Near unlimited Dynamic Range, Visceral Bass impact with extended natural decay, and expansive yet precise imaging. These three concepts were the design goals for The Arcus, a no compromises, unapologetic, attempt to reproduce a live music experience in a typical sized listening room. And to make it even more challenging, we tasked ourselves with meeting these goals in a small footprint.
These goals presented many challenges. First of which was sourcing a woofer that could produce the near unlimited dynamics of a live event combined with high-sensitivity, and refinement/nuance through the critical mid-band. Many drivers and implementations were experimented with and auditioned before we discovered the titanic driver manufactured by the American company Acoustic Elegance. Of all the woofers tried, only the Acoustic Elegance TD10M gave us the combination of characteristics required on paper, and delivered in the real World as well with extended periods of sonic bliss without a hint of fatigue or perceived effort.
To keep up with such a capable woofer, an equally impressive tweeter needed to be properly implemented found as well. Recent years have seen major advances in the production of Heil type Air Motion Transformer (AMT) tweeter. The Beyma AMT is one such example. It combines high sensitivity with a very large radiating surface and a conical waveguide to boost output capability as well as control/match directivity to the woofer. It is also impressive in it’s power handling, and makes an ideal match with the AE woofer, one of the very few tweeters in existence that can keep up. The two drivers together make a compelling combination.
After hours and hours auditioning these drivers together, shuttering ourselves into our primary listening, a final crossover was found which gave expansive and yet pinpoint image, authoritative and fleshed out bass into the mid 40’s, some of the best mid-bass on the planet, and breathtaking dynamics. The Arcus is an enigma, a very unique offering in the World of hi-fi. You will receive a monitor speaker with incredible resolution and refinement, but also high enough sensitivity to run with for instance a 9wpc 300B SET. But also one that can handle insane volume levels without strain or onset of fatigue. No longer do you have to settle for the trade-offs typically inherent in high-sensitivity loudspeakers, the Arcus can do it all. We tell customers often that the Arcus may not be the best speaker in our lineup at any one thing, but does everything very well. And when it’s all tallied up, the Arcus is an incredibly fun toe-tapping experience!
