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 toy for tough chewers. Just don't expect a miracle!
Flavor Name: Bacon, Size: X-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle. If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed. When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars. This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Durable, almost nondestructable, exelent guality bone.
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
We bought these bones about fifteen years ago and now I've been looking for them and was not able to find them. I've almost given up hope that they're still on the market. We finally found them yesterday. Since then we only have one small left and after a long time of gnawing on it, our two 50lb Labrador/German shepherd puppies are arguing over it. Even though they have other rubber and plastic toys that are supposed to help their teeth and gums, these two have taken a liking to this small size nylon bone and literally fought over it. The are aggressively protecting it like it would be real bone. I can't wait for the new two durable nylon bones to arrive. They are great for their teeth and gums. Thank you for continuing to make them. Dale and Jarmia Rogers

Super tough, great value, addictive toy for my dog.
Flavor Name: Bacon, Size: X-Large
My dog pit/Shepard mix, loves this bone, and I love it because she can't kill this one like all those other Kong toys. She had a smaller nylabone, she killed it but took about a year, this larger one, she won't be able too that soon. Hard expensive Kong things, wouldn't last a couple months with her. So now, 3/17/2026 its still going. One end is gone, but the green part and other bone end she's working on.

Great for Mega Chewer
Flavor Name: Bacon, Size: X-Large
Got one of these for our Rodesien Ridgeback when he was a puppy, and it worked well. So, when my daughter rescued two medium-sized dogs (one is an Australian Cow dog mix, and the other a Plott Hound mix) it was a no-brainer. The Plott Hound mix has jaws of steel and destroys anything and everything he can get his mouth around, except items from this maker. This is the only toy brand I've found that he doesn't demolish in under 5 minutes. Oh, and I'm stunned he can put bite marks in it. The Rodesien Ridgeback didn't even do that when he was a puppy, so I was surprised. However, that being said, the toy is holding up to hours of abuse. I had to buy additional toys because they don't like to share. Update on 01/09/20: these are still holding up to repeated abuse.

Sensational Toy By Nylabone Keeps Your Best Freinds Teeth Snow White!
Flavor Name: Bacon, Size: X-Large
Our Bull dogs LOVE these bones. Long time Nylabone fans they've been making quality dog toys here in the United States for over fifty years. The nubs on the end of the bone age great for cleaning teeth and massaging bones. The center is softer but still holds up to even the toughest aggressive chewers. For whatever reason this isn't a "favorite" toy in the sense that they drag it around a few hours a day but they do play with it and we replace them when the ends start to shred - which should be done with all nylabone chew toys. The price on Amazon is virtually half the cost of the big box pet stores so it's affordable - not to mention fun to replace their toys and try new ones often. Plus with a Prime membership almost every item we buy ships with Free two day shipping - making the deals even that much sweeter.
