Astra Upgrade Speaker Kit

Premium Inspirit Kits


Incorporating a lightweight design, Inspirit brings out the complete value of her elements.

  • A Full Ascendance:
The four speaker units included are hand-toned with our EISA-award-winning expert to extract each musical work’s lively essence. No matter if it is road trip season or another daily commute, Soumatrix gets it all.
  • Coaxial wonder: 
Each Soumatrix speaker unit builds one tweeter and one woofer on one single axis. This unique design creates a greater cinematic sweet spot that you may enjoy in any of the seats.
    • OE Grade:
    Crafted with original equipment manufacturers, these speakers are designed to provide a smooth DIY-friendly installation experience, long-lasting sound quality, and a non-restrictive commitment for Opel standard trims.
      • Built to Impress:

      Dual-layered, honeycombed glass fiber combining with natural cellulose woofers presents a smooth transparent sound. Tainted and damped aluminum-magnesium alloy tweeters secure maximum stiffness, high damping, and fast propagation.
      These speakers made in Germany are designed to bring refreshing thrills. An impressive upgrade to your car's voice can be achieved with or without amplifiers.
