The upgraded Arx A1b has improved bass and resolution. Like the original A1, the powerful new A1b features a planar magnetic tweeter and a high performance SplitGap woofer. The upgraded A1b is perfect for compact high-output systems.
Arx A1b monitor loudspeaker
The Arx A1b is an upgraded, performance-oriented stand monitor that resets the standard for affordable speakers in this class. The A1b's advanced technology creates a tremendous three-dimensional soundfield not thought possible for such a modest cost.
What's special about Arx?
The A1b's second generation Arx flat-panel "planar magnetic" tweeter replaces conventional domes and cones with a nearly weightless thermoplastic "leaf" driven by an intense magnetic field that saturates its surface. The result is a lightening-quick response, high linearity, and surprisingly neutral and extended high frequencies. High frequencies from the Arx A1b take on an immaterial quality and simply do not sound like those from an economy loudspeaker.
The Arx A1b loudspeaker also guarantees powerful, low distortion bass performance - nearly 10Hz lower than the original A1. Arx "SplitGap" bass technology drives the speaker to both higher output and lower distortion. Arx licenses the dual-gap, low-distortion XBL2bass technology, which includes a pair of force-generating magnet gaps where conventional drivers use only one.
SplitGap provides about twice the linear cone excursion and piston volume displacement over anything we're aware of in the A1b's class. SplitGap also dramatically lowers speaker distortion. The Arx A1b's tuned bass alignment and larger net internal volume generates response to impressive new depths for a bookshelf/monitor speaker.
We engineered the Arx A1b to give you enormous dynamic reserve so turn em up and enjoy even when they're pulled out into the room on speaker stands - this is one compact economy monitor that won't get harsh, in your face, or weak in the knees. These twin technologies combine for great clarity and spell-binding dynamic contrasts. Even at only a little over a foot tall, the Arx A1b goes even bigger then the original A1 for a fraction of the cost of usual "high end" systems.
The A1b is a smart looking, computer-milled enlosure, assembled and finished to high professional standards by real loudspeaker pros. It's finished in stealthy simulated black ash. A removable black knit grille, rear-facing aerodynamic tuned port, and heavy, single input terminal pair complete the speaker.
The A1b is individually serial numbered, and is sold, packed, and ship in pairs.

The Arx A1b is designed with adequate diffraction step compensation and dynamic reserves to allow its use as a main loudspeaker. This compensation equalizes the speaker's frequency response so that as omnidirectional low frequencies begin to wrap around the cabinet, the more directional upper frequencies remain tonally balanced. At higher levels the A1b holds its own and remains composed where other inexpensive speakers become congested, shrill, and amusical.
The Arx A1b also includes a convertible bass refex system with an aerodynamically-flared rear port that provides bass reinforcement at very low frequencies. This port is designed for high flow - it compliments the A1b's very long throw woofer's much higher output.
An optional free charcoalester foam plug can be used that converts the enclosure tuning from bass reflex to acoustic suspension, allowing the A1b to be used as a bookshelf or effects speaker closer to boundaries. If the converted A1b is used in an active highpass setup, acoustic suspension may aid AVR or processor crossover integration to the system's .1 channel active subwoofer. The convertible A1b bass system gives the speaker added flexibility for numerous setup options.
The Arx planar-magnetic tweeter.
The A1b's long-throw woofer has a treated cellulose cone for natural, detailed sound.
The A1b's high-power crossover network sums the drivers seamlessly. Like all Arx models, the A1b has been engineered for a consistent soundfield with excellent acoustical power distribution. Inside we've used heavy gauge, low-loss inductors, premium film capacitors, and non-inductive resistors, all CAD-designed and then tuned by ear over dozens of hours of critical listening.
For a complete Arx system, select the A3 tower speaker for main duty and the A2 for excellent center-channel performance - the Arx A1b speaker shares drivers and acoustics with the rest of the line, allowing you to mix and match easily.
The Audio Insider is proud to present this extraordinary line of products at very special prices. Try a pair of Arx A1b's anywhere you need excellent resolution, lowest distortion, and the most satisfying sound in its class.

Arx speakers are based on two important, groundbreaking technologies and we've got both in one economical performance loudspeaker. The first is the "planar-magnetic" high frequency technology. The second is the radical new Arx "SplitGap" bass technology.
All Arx speakers use a special planar magnetic flat-panel tweeter with superb high frequency characteristics. This special device is quite unique to speaker systems of the modest Arx cost. In fact, this device is typically found in speakers costing many times more than Arx.
The planar magnetic tweeter consists of a feather-light membrane driven uniformly by a magnetic field created by intensely powerful Neodymium bar magnets. Foil conductors bonded to a thermoplastic membrane carry delicate high-frequency signals nearly perfectly. Lacking the complex mechanical interplay of the many parts that comprise conventional tweeters, the planar magnetic tweeter's sound has both great detail and excellent dynamic power. Music and soundtracks are imparted with the natural, neutral high frequency detail needed for excellent definition as well as the robust output required for today's dynamic recordings.
The planar magnetic tweeter also possesses high thermal capacity and electrical power handling, together with controlled dispersion, making it sure to keep its cool during peak demands and to do so predictably within the listening environment.
Compared to usual domes and cones, you can see just how different Arx planar magnetic tweeters are.
The entire sound-producing assembly has been replaced with a simple emissive diaphragm of flat, micro-light high temperature polymer film. This diaphragm has a flat response to beyond 30kHz, a half octave beyond most dome tweeters. In an Arx tweeter, there's less to resonate, less to distort, and less to fail.
The Arx tweeter's voice coil is an evenly distributed pattern of ultra-light foil. No other parts are needed so there's nothing to weigh down the moving surface.
The flat, ultra-low mass Arx tweeter diaphragm is energized by rows of powerful Neodymium magnets, ounce for ounce about five times more powerful than those in regular tweeters.
Arx's special tweeters have more radiating area, given them a reduction in intermodulation distortion you can hear and measure - your music and soundtracks simply sound clearer, more effortless, and more transparent.
Unlike the lesser domes found in common speakers at Arx's low cost, the planar magnetic or "ribbon" tweeter has lower distortion at every volume level.

Midrange / Midbass
All Arx models mate special tweeter technology with high-power "SplitGap" midwoofers with licensed XBL2 dual-gap technology. These drivers feature radically higher excursion and very low distortion. All are precision-tuned to each Arx enclosure for very good quality bass from compact enclosures.
What is XBL2 SplitGap? This rare licensed technology adds a second voice coil gap and significant distortion-reduction - think of it as a turbocharged regular woofer. SplitGap's second drive gap is carefully positioned so that where a conventional woofer's gives up, an Arx cone shifts into acoustic overdrive and virtually doubles its output. For an audible bonus, SplitGap slashes distortion at the same time.
SplitGap woofers have shorter voice coils for lower moving mass and lower inductance, giving Arx speakers excellent midrange articulation.
Copper in the SplitGap motor reduces distortion-causing flux modulation, greatly extends speaker response, and improves thermal capacity for higher power handling.
SplitGap motors have more uniform cone drive, lowering distortion at any point of motion.
Compared to regular woofers, SplitGap has 40% less motor distortion. Arx XBL2 motor technology also nearly literally doubles the speaker's "volume displacement" - the total amount of air the woofer driver can displace - for unexpectedly deep and dynamic bass.
The Arx high performance midwoofer, while having the broader midrange dispersion and higher extension of a 5.25" cone, can move as much or more air as a good 6.5" woofer. SplitGap greatly reduces distortion, runs cooler, and can take more power.
All Arx models include precision crossover assemblies optimized for linear power and predictable dispersion. Components are best quality, featuring epoxy circuit boards, low-loss inductors and premium film capacitors for critical signal areas. All models are designed for in-phase output, flat response to industry standards, and optimized off-axis dispersion. Each is further tuned by ear for the highest degree of musicality we can give them, a critical step and the final element of the Arx sound,
Extreme Arx performance requires a heavy, braced enclosure, which all models have. All models rely on precision, computererized mill-cut 18mm thick reinforced cabinets from one of the best cabinet houses in the industry. While not fancy, these enclosures are perfectly tuned and heavy enough for great sonics at any level.
Lastly, extreme Arx value calls for conservative finishes, which is why every Arx speaker is finished in simulated Black Ash PVC. Arx finishes clean easily, blend in, and with reasonable care, last a long time.
