Features of ESP Subwoofer

  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses an effective carbon fiber-based cocktail to provide you with the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Provides ultimate linear control at high excursions while enabling dynamically sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow for a stepless control system. The harder you control it, the more control you gain.
  • Tuned Spider System (TSS) - Each suspension is tailored to specific performance characteristics, e.g., High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes the spider diameter, cone diameter, suspension travel, and acts as a secondary short circuit ring, providing additional heat dissipation for better heat flow from the coil.
  • SuperCharge option available!

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
