HELIX IK S8

Flat dimensions – deep bass

With the shallow HELIX IK S subwoofers, the realization of particularly flat and compact enclosure designs shouldn’t be a problem anymore. Its extremely low installation depth opens up new installation possibilities that do not require making any acoustic compromises at all. Additionally, thanks to the use of large voice coils and its low resonant frequency, the HELIX IK S series delivers an absolutely stunning bass performance, which is in no way inferior to larger dimensioned woofers.

Smart down to the very last detail

The enormously stiff sandwich paper cone in conjunction with our heavy-duty drive system easily converts amplifier power into powerful sound pressure without any compression effects, while simultaneously demonstrating finesse when it comes to more subtle beats. A special highlight: the magnet system has a threaded hole on the back and thus allows the woofer to be fixed to the back panel of the enclosure. Since every millimeter of depth counts in flat constructions, enclosure vibrations are effectively reduced – even with thin walls.

Flexible Connection

Designed as a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) variant, you can find the right low bass specialist for any amplifier configuration to get the maximum performance out of it.

"All inclusive" for self-made enthusiasts

In addition to the high-quality connection terminal with gold-plated screw terminals, a 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 or DSP settings in our technical data sheet.

Features

  • Chassis with particularly low installation depth – optimized for compact and shallow enclosure constructions
  • 2 x 2 Ohms dual voice coil for flexible system configuration
  • Magnet system with threaded hole on the back – allows screwing to the back panel of the enclosure for stabilization and reduction of enclosure vibrations
  • Extremely stiff sandwich paper cone
  • Long-excursion rubber surround for highest mechanical rating
  • Rugged magnet cover with HELIX lettering for perfect magnet protection
  • Enclosure connection terminal, grille and gasket included in delivery

Comfortable cotton briefs
Color: Beige - Set 17, Size: Large
Very pleased with this underwear. Purchased a second pack of four. Fits well, very comfortable and gets softer after washing. Comfortable stretch in the waistband without being too tight. I have had several abdominal surgeries in my life, and my belly will never be flat. I am also elderly and appreciate the fabric being cotton.

W knows how to fit us biggies
Color: Black - Set 3, Size: 7X-Large
wirarpa is the only company that makes honest to goodness full coverage briefs...I have the boy short biker length ones and now these......They have a wonderful wide top of panty , no digging in because it's wide, always comfy Wirarpa knows that women who are large/ fat etc have bellies and these are as close as you will get to feeling like you wearing nice panties .....no dig into crotch where panties meet thigh...... no more hurt skin from sitting down , these don't dig in Pricey but I have wasted lots of money before searching. so I buy enough and have a good supply, you never know when prices will keep climbing Soft, no seams, wash in washer & hang on line/hangers to dry, never put in dryer Biker length ones I wear around the house when alone ................ Only complaint: not all styles in my 5X size, you miss out on other styles but these two : panties and long boxer are my staples....... a company that KNOWS how to make decent big woman undies should offer all styles
