The new ARC Audio RS Series speakers combine incredible technology and design to give crystal-clear sound to music fans and audiophiles all over the world. The RS project began several years ago and is a partnership between ARC’s US and Danish transducer development teams. The project’s purpose was to create a line of speakers that redefined precision, detail, and power handling while maintaining a shallow mounting design that was simple to fit into modern vehicles.
RS Series speakers are sold in pairs by size and were designed as an à la carte solution for active system designs. The RS 6.0 6.5-inch midrange/woofer, the RS 4.0 4-inch midrange, the RS 3.0 3-inch midrange, and the RS 1.0 1-inch tweeter combination are currently available. Every component used in the construction of these speakers was created from the ground up for maximum performance and dependability.
The cast aluminum basket of the RS 6.0, RS 4.0, and RS 3.0 speakers provides robustness and optimum voice coil cooling. Flat spiders are found on all three drives, ensuring superb linearity in both forward and reverse motion. Each midrange and woofer cone is made of hard-pressed paper, which mixes bamboo and pulp papyrus fibers for a balance of dampening and strength without adding too much mass to the high-frequency response.
When compared to speaker designs that employ a phase plug, ARC Audio chose a design that uses a dust cap to provide better efficiency and a smoother overall frequency. The curved ridges on their unique parabolically formed top increase strength and reduce resonance at high frequencies. The dust caps have also shown to be childproof since they have withstood being poked by small, fast-moving hands.
The handmade, ultralight, quality CCAW voice coils are wrapped around glass fiber, resin-pressed, aluminum-reinforced voice coil formers for superior thermal power handling and a lower total moving mass in the ARC Audio RS SpeakerRS speakers.
A clear-coated, one-piece T-yoke assembly is machined to specification on the back of the 3- and 4-inch speakers for precise tolerances and greater efficiency. The RS 6.0 features two-piece construction with a huge cooling vent in the middle that is black-coated to help transmit heat away from the voice coil.
For outstanding efficiency, a donut-shaped N42SH neodymium magnet produces an exceptionally powerful stationary magnetic field. This neodymium grade can withstand temperatures up to 300 degrees Fahrenheit without degrading. The inductance-reducing copper slug was added to the top of the T-yokes by ARC Audio to reduce inductive distortion and improve clarity even more, especially at high power levels.
The RS 1.0 tweeter features a segmented, adjusted and damped rear chamber for increased performance at lower frequencies, as well as a 1-inch fine silk diaphragm. The chamber is tapered to avoid resonances that could cause distortion in the transducer’s output. These tweeters operate well in both two-and three-way configurations, with a resonance frequency of 900 Hz.
Terminal studs on the back of the driver are used for electrical connections, and premium ring connectors are included with each set. To match the aesthetics and appearance of your system, the driver can be utilized with or without the threaded aluminum mounting ring.
ARC Audio has engaged in comprehensive testing protocols for the original design and each unit that comes off the assembly line, as with any premium driver made exclusively for automotive audio applications. Power handling tests entail eight hours of band-limited pink noise at the rated power level. After that, the driver’s parameters, look, or functionality may not change significantly.
The test was then performed for an extra eight hours at twice the rated level, then for an additional eight hours at three times the rated level to guarantee that owners can enjoy their music at realistic levels. This step-up power process testing was carried out endlessly until the drivers failed, with the sole acceptable failure being a burnt voice coil that exceeded the recommended power handling specifications.
Each speaker is subjected to a mechanical rub and buzz test before being individually tested and documented, utilizing LMS test equipment to confirm the response performance of each driver. The test computer examines the driver’s output and assigns a storage spot in a 10-by-10 grid for matching with another driver that is as near to the original specification as possible within allowable limitations. The matched sets that result make system tuning as simple as feasible for the installer.
Without a doubt, the ARC Audio speakers are high-end. However, when paired with an SP2000, they are taken to a whole new level.
Contact Music In Motion and request a demonstration of the new Arc Audio RS Series speakers if you’re interested in taking your car stereo system to a whole new level of detail and precision. The effect will be nothing short of spectacular when combined with a correctly tuned digital signal processor, high-quality amplifiers, and competent installation.
