Arc Audio X2 Series 502 High-Efficiency 5.25" Coaxials

Exceptional performance and stunning sound quality isn’t something that should be reserved only for the highest cost and most extensive level of installations. The X2 Series speaker line from ARC Audio is proof you should never judge a book by its cover and that price doesn’t always dictate the quality of the sound and performance of a speaker.

The new X2 Series speakers from ARC Audio combine multiple new features generated and developed in conjunction with real-world feedback from retailers and consumers to produce a line of OEM standardized direct fit upgrade solutions with amazing sound quality, awesome performance, and incredible value. With nine brand new models, there is an X2 speaker for almost every application.

All X2 Series speakers feature brand new custom-designed, proprietary stamped steel baskets with complete considerations for fitment and end performance in mind. The eight-spoke design includes compound curves to increase rigidity and eliminate resonance for clean sound reproduction and at optimized cutout diameters to allow for perfect fitment into OEM applications. Combined with extensive ventilation beneath the spider mounting ledge the new basket design aids in cooling the voice coil assembly and increases linearity at high power levels and helps improve low-frequency response with minimized rear spider compression form and main moving parts.

The all-new woofer cone design in the X2 Series of speakers uses an injection molded polypropylene construction with stranded glass fiber reinforcement to reduce cone breakup and resonance at high excursion levels offering an optimized musical experience at any listening level. Combined with a specifically designed Butyl rubber surround, the X2 Series speaker line promises years of reliable service in even the most extreme temperature conditions without the breakdown and wear and tear found in traditional surround material designs.

The X2 coaxial speakers feature 20mm silk-dome tweeters with a Y-35 neodymium magnet for excellent efficiency. An integrated phase plug improves off-axis response and dynamic stability at all volumes.

Each set of X2 Coaxial speakers uses high-quality audio grade polypropylene capacitors for the onboard tweeter crossover. These premium caps deliver the improved high-frequency response and a much smoother transition between the tweeter and midrange with predictable, long-term reliability.

The component speakers use the X2 5.2 and X2 6.2 component speakers use the same optimized 27mm tweeter found in the X2 1.0 set. This large tweeter includes a tuned rear chamber to provide smooth and elegant upper midrange response in a robust and durable design that works well with all types of music. The low resonant frequency of the X2 tweeters in the X2 component systems system improves imaging when the tweeters are mounting on the dash, in sail-panels or A-pillars.

The passive crossover networks included in all X2 component systems include second-order -12 dB/Octave filters to improve imaging and soundstage characteristics. Imaging and staging are improved further with high quality, hand-matched polypropylene capacitors for onboard tweeter crossovers. Just as with the coaxial speakers, poly caps dramatically outperform their electrolytic counterparts regarding performance and reliability.

An important area of focus during the development of the X2 Series was to ensure that these efficient drivers would work well at head unit power levels and when connected to amplifiers like the X2 450.4, The KS300.4 or even the amazing new DSP-equipped PS8-50. Strong magnetic fields, low-mass cones, and balanced compliant suspensions ensure excellent efficiency while large motor assemblies with large-diameter voice coils ensure that physical power handling is under control.
