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
- 1 x 2 Ohms single voice coil
- 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

An amazing book!!!
Format: Kindle
This was another amazing book by Piper Rayne! The nest is one of my favorite series (top 2 of all time)! The love story between Kyleigh and Rowan was beautifully written! I love the found family in this series! They always tell each other when they are messing up and always help each other fix their mistakes! The banter between them is soo well written.
I highly recommend this book and the audiobook! The full cast audio book is beyond amazing!!!! It truly brought this wonderful story to life! The narrators did a fantastic job and really made me feel like I was a part of the story! I am such a sucker for a full cast audiobook! Another great job Piper Rayne and all the narrators that helped tell this awesome story!!!

I absolutely loved this book! Avery and Knox were beyond perfect for each other. Rebecca Jenshak did such an incredible writing this book and these characters. The brothers relationships in this family is wonderful. Everyone steps up to help take care of each other and it is heart warming. This book had low angst which I loved! I am really enjoying the start to this series and I cant wait to read the next book!
The duet audiobook was incredible! Erin Mallon and Teddy Hamiliton did a fantastic job bringing this book and these characters to life! I highly recommend this book, audiobook, and series!

Banter, a bit of angst, found family, and a hot, tattooed bad boy who’s really a totally softie
Format: Kindle
This was a fun, easy read. It has all the things I love in a sports romance...banter, a bit of angst, found family, and a hot, tattooed bad boy who’s really a totally softie.
Knox is kind of a mess at the start. He’s super talented, but has a reputation problem after getting kicked off his motocross team. He’s desperate for a second chance, which leads him to Avery, a former Olympic gymnast recovering from an injury. She’s trying to get her confidence back, and somehow these two end up helping each other.
They can't stand each other at the beginning. He says ALL. THE. WRONG. THINGS. Evenutally, their friendship builds into something more. It felt natural and sweet. I liked that they both had their own stuff going on. Avery’s inner struggle was really relatable, and Knox’s bond with his brothers, especially with Flynn, added a ton of heart to the story.
The beginning was little slow, and the ending felt a little rushed. Overall, though? I had a great time with this book.

My Review
Okay… I’m not even sure how to start this review so I’m just going to explain my 3.5 rating. I want to begin saying, there really wasn’t anything that made this book bad. I have read previous books by Rebecca Jenshak, and I LOVED them, rated them 4 or 5 stars, but for some reason, this book took me about 35-40% of the way through to finally get into it and enjoy it. Once I got past that point, I absolutely loved it. I’m not sure if it was a mood I was in, or just that it was a completely different type of sports romance, but something just didn’t grab my attention soon enough. I loved Avery and Knox, two complete opposite kind of people, which made for a ton of banter. I loved that we were able to get inside of the head of Avery, an Olympic gymnast, who was recovering from an injury, and see what that process of the road to recovery and competing again at 100% looked like from a mental stand point. Knox was this character that you got immediate bad boy, I don’t do relationships and just hook up vibes from, but slowly throughout the book you can see Avery and Knox going back and forth and breaking each-others walls down. They began hanging out more and doing more things together, but didn’t want to define what they had because it worked for them and what they needed at the time. This book had different aspects of a relationship that you don’t see in other romance books, such as long distance. I thought the end of this book was left more open ended than closed, and I felt it just kind of ended, or the epilogue wasn’t really a cherry on top, it was more so just the sprinkles. BUT, overall, I would recommend this book to read to others; the spice in this book was AMAZING (there may or may not be a spicy motorcycle scene hehe), the banter was great, we really got a feel and understanding of each character too. I wonder if I read it again, or read other books in the universe to get some background on this story, maybe my mind will change on my rating; but for now it’s a solid 3.5 for me.

Good book
Format: Kindle
This is my first book by this author and I loved it so much. Such a cute story. I absolutely loved reading Knox and Avery's story. Knox is a motocross racer and Avery is a gymnast. Knox lost his spot with his team for not being a team player. He is bummed out because racing has been all he really wanted to do. Knox lost his mom when he was a teenager and he took on a pretty big responsibility helping take care of his brothers. He has an older brother who went to college and then two younger ones that also ended up going to college and then there's the youngest one that's a senior in high school. Knox is a great big brother but really wants to race so his friend Colter, who does freestyle tricks on bikes, talks him into trying to do trick riding too.
Avery hurt her knee a bit ago which she did therapy for but is really aware of her knee now and just doesn't have the confidence like she used too. Avery goes out with her friend to a party to get out of her head and there she sees Knox. He's on his bike but he almost got her and from there it starts there relationship of having snarky comments to each other. Avery helped Knox' friend Colter do some gymnastic workouts to get his strength and learn some tricks for his trick riding. Colter recommends Knox work with her too. Knox takes him up on this because Knox needs this to show people in motocross racing he can be a team player.
Knox and Avery end up getting a long better and you can feel the chemistry between the two but both don't want a relationship for different reasons. Things heat up between the two of them. Lots more happen in this book and you will want to read to find out what that is. Will Avery and Knox be able to get over their fears and be together? Have to read to find out. Thank you Rebecca Jenshak for this book.
