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

Good quality fits 2025 Civic Hybrid
The filters are good quality. I did not find any instructions, but then again, the tube is full of them. Compaitble with 2025 Civic Hybrid. The engine filter have a bit of a chemical smell, but the air cabin filter does not. The cabin filter has an interesting yellow color.

Quality filters for a decent price
The engine filter is model # JMAJ20. I am not sure of the cabin filter model #. I have a 2026 Honda CRV Hybrid 2.0L Sport Touring. These should fit as almost everything matches between the 2025 and 2026. I have not yet needed to swap the filters in the new vehicle. These filters will be stored for future replacement. The filters appear to be well made. This is a decent price fortwo filters. The engine filter's gasket is a little wavy but it should be ok to form fit once inserted into the car. The engine filter is in a retail box without a plastic wrapper but the cabin filter is just a plain cardboard box inside a plastic wrapper. This might be challenging to remember what is in the box later once the filter needs to be replaced unless I write the information onto the box. I am unsure if the lack of a wrapper for the engine filter will affect the filter while stored. I did not notice a smell to these but I am not sensitive to smell. I would get these again.

Great value perfect fit.
At a fraction of the cost of brand name filters, these are an exact match and make it affordable to actually change your filters on a regular basis. Great! Installed on a 2025 CRV hybrid touring.

Solid replacement filters for 2025 Honda Civic Hybrid. Engine and Cabin 2.0L Engine
Good value replacement filter kit. Fits perfect for 2025 Honda Civic Hybrid with 2.0l engine. Fairly easy to install once you know how to access the filters. Center rear of the engine bay and behind the glove box. These are as high a quality as the stock filters. I changed mine at 12300 miles and I waited too long. I should have done them at 10,000 max. The cabin filter maybe could have been stretched a bit but the engine filter could have been changed at 8-10k. I would never wait so long again.
