While designing this series superiority was our goal. We have designed these for the audio enthusiast that dares to push the limits. After countless hours of abuse and testing I’m proud to introduce the RS Onyx Series. The RS Onyx Series is available in 12” and 15” featuring a 4” 4 layer FW Aluminum VC, 5 stacked 9.25” nomex progressive spiders with triple sewn leads, and a FEA optimized triple stacked motor with an aluminum shorting ring and spacers conservatively rated 2500 watts rms / 5000 watts peak

  • BOX HEALTHY RECOMMENDATION

    Every vehicles applications, equipment, tuning, wiring, ext all play a factor in making sure your woofers are playing clean signals to avoid any clipping. Our products have the reputation of taking some of the most abuse in the industry for its given power rating, but to ensure the longevity using the right air space and scoping for a clean signal will be sure to have a lasting daily resilient subwoofer. 

     

    Suggested Healthy spec range.

    Rule of thumb lean towards smaller enclousre if clamping @ or more than conservative power. Lean towards bigger enclosure clamping below conservative power

     

    Ported enclosure

    2.9ft-4ft tuned @33hertz with 12-16sqaure inch of port area per cubic foot.

The last 3 box designs I've purchase were all 150+ db certified in the lanes, your results may vary depending on vehicle and power but they definitely know what they're doing. Well worth the money !
