HELIX IK W8

Stunning bass performance out of compact dimensions 

With the new KW chassis, we’re expanding our IMPACT subwoofer lineup, offering powerful drivers for use in very compact enclosures. Especially when it comes to the most efficient usage of available space in the vehicle regarding an individual enclosure design, these woofers create completely new installation possibilities without ever compromising the acoustic performance.

Clever down to the last detail

The extremely stiff cone made of hand-scooped paper fibers in connection with the heavy-duty driver system not only converts amplifier power easily and without compression effects into loads of sound pressure, but also scores sonically with subtle beats. 

Flexible connection – 2 x 2 or 1 x 2 Ohms

The chassis are available as 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) version. Thus, these subwoofers always offers the right solution for every amplifier configuration to get the maximum performance out of it – whether mono, 2-channel or even multi-channel amplifier. 

"All inclusive" for self-made enthusiasts

In addition, the solid protective grille and gasket are also included. For optimal bass performance in DIY installations you can find recommendations for sealed and vented enclosures with all parameters such as net volume, port tuning frequency as well as DSP settings in our technical data sheet.

Features

  • 2 x 2 Ohms dual voice coil for flexible system configuration
  • Extremely stiff, hand-scooped paper cone for outstanding impulse response
  • Double ventilated voice coil for minimum compression effects and high power handling
  • Long-excursion rubber surround for highest mechanical rating
  • Solid push terminals
  • Powerful magnet system for compact enclosures
  • Rugged magnet cover with HELIX lettering for perfect magnet protection
  • Grille and gasket included in delivery

Great play and chew toy!
Pattern Name: Star
The dogs love these! They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
