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

Dressy without the struggle
Color: Deep Gray, Size: 7
These are really nice little dress pants for boys. Perfect for church, weddings, or anything where they need to look a bit more put together. The big win for me… they’re not stiff. My kid didn’t fuss about wearing them at all, which says a lot. They look clean and polished but still have some comfort to them, which is exactly what you want for this kind of thing. They also seem pretty well made, nothing fancy but solid for the price. Easy win if you need dress pants a kid will actually wear.

Nice suit pants
Color: Black, Size: 14, Color: Black, Size: 14
Sorry they are covered by a long shirt in this picture, but they are great pants! They are fully adjustable with a huge range of buttons for sizing the stretchy tabs inside. They are made of a soft, durable fabric, and my son said they’re comfortable enough to wear all day. They looked really nice, though since we had to cinch them tight for this super skinny guy, and belt might have helped to cover up the bunching in the back.

Dress pants did not fit right on my grandson. Too big in the waist and wasn't long enough. I returned the pants.

Smart-Looking Pants That Fit Well
Color: Navy Blue, Size: 8
I had my son wear these for a church, and they looked sharp without being too stiff. The adjustable waist makes them comfortable, and the fabric feels durable enough to handle a few hours of running around. They held their shape well and didn’t wrinkle too easily. After a couple of wears, they still look crisp and clean. The overall fit and finish make them feel like a well-made pair of dress pants.
