Key Features

  • 12" Long-throw Driver
  • Dual 12" Bass Radiators
  • Class D - 500W RMS Amplifier (1500W Peak)
  • Frequency Response (+/- 3db) 25 Hz → 150 Hz

Massive, uncompromised bass performance, from our most powerful subwoofer ever. Unique technologies add unprecedented clarity, power and seamless system integration. 

3XR™ Architecture

The DN12’s 3XR Architecture provides triple the bass-producing radiating surface area of a traditional 15” ported subwoofer. This extra surface area moves more air, enabling the DN12 to play as loud and low as a two similarly-sized 18” ported subwoofers. And because 3XR doesn’t use ports, DN12 also provides crystal-clear bass with no port noise distortion.

Passive Radiators

As the core technology behind Descend’s 3XR Architecture, its passive bass radiators enable the DN12 to play as loud and low as a 15” ported sub without unwanted port noise distortion. Passive radiators also deliver a smooth frequency response like a sealed sub, but with the port-like ability to play louder and lower in a smaller enclosure.

What you get is the best of both worlds: louder, clearer bass then a ported sub from a smaller enclosure than a sealed sub.

Pure Impact

Powered by Class H digital amplification, and with an advanced 56-bit DSP that includes three custom EQ modes, DN12 plays exceptionally impactful bass down to 25Hz.

Custom Class H Digital Amplification

The DN12’s advanced 1500W peak Class H digital amplifier delivers continuous power to cleanly reproduce sustained bass below 25Hz. With real-time monitoring and adjustments to the sliding rail voltage, the DN12 delivers considerably higher power during short, transient peaks such as bass drum kicks and on-screen artillery blasts.

Advanced 56-Bit DSP

The advanced 56-bit Digital Signal Processor (DSP) extends and improves the DN12’s bass response. The DSP tightly monitors and controls the woofer system to prevent distortion and woofer damage at ultra-high volumes with a minimum of audible artefacts.

Built-in EQ Modes

With three built-in performance EQs modes, the DN12 can be optimised to your room and listening preferences, and adjusted to match whatever you're listening to.

Team Player Control and Customisation

With breakthrough technologies such as Intelligent Phase Control™, easy settings management with its dedicated remote control, and advanced custom integration capabilities, the DN12 is easily optimised to the specifics of your system.

Intelligent Phase Control™

Intelligent Phase Control™ provides a full 360 degrees of customisable phase adjustment, always centred around the settings of the low-pass filter. This provides the ability to tune the subwoofer for minimal group delay between speakers and a flawless blending experience between your speakers and the subwoofer. 

Remote Control with On-sub LED Display

Easily adjust the DN12’s volume level, phase, and EQ with its slim remote control. There’s no need to constantly get up to manually change settings or wonder if you’ve gotten them right.

Multiple Subwoofers

While a single subwoofer can add bass and enhanced realism to any system, it may not provide consistent frequency response throughout the room.

When two or more subwoofers are properly employed throughout the room, sound waves disperse more evenly, flattening the frequency response. The result is smoother bass throughout the room, helping to eliminate boomy locations or dead spots.

Custom Integration

With both 12V input and IR pass-through, you have the ability to pair the subwoofer with most control systems and place the subwoofer wherever you want in the room and still experience full functionality.

Please do yourself a favor and read it!
Format: Kindle
So I saw this book on Instagram from someone I follow and was immediately intrigued. And let me tell you I am so glad I picked this up. I literally could not put it down and read it in a day. I am absolutely in love with evie and Maddox. I mean seriously Maddox 😭 I love him so much and that poor brute has been through so much but is just the most lovable thing. And Evie ugh that woman has been through it but is so strong. Every side character in this book is just as amazing too. The twins, Vic, Lou, and don't even get me started on the other Wilder boys😍 this book had everything, it's emotional, heartbreaking, thrilling and just an all around amazing love story. This will be a book I definitely re-read and I don't do that often. Also need to buy a physical copy like ASAP. But what I really need is Mercy's story like, yesterday. He is absolutely my favorite side character in this book and I will be so sad if he doesn't get his own story!

Grumpy Sunshine, Small Town Romance
Format: Kindle
ARC Review 3.75 ⭐️, rounded up to 4 ⭐️’s. I really enjoyed the book and think the author did a good job of drawing her readers into this couple’s world. The characters were complex, but well developed. Even the side characters were amazing. The setting of the story was well thought out and came to life on the pages. There were definitely some plot twists that I didn’t see coming, and some that were anticipated, but with the way they were timed I was still shocked when it happened. And while this wasn’t the spiciest book I’ve ever read, the spice was definitely there. When it hit, it hit hard! Overall, I really enjoyed Evie and Maddox’s story. There were some things that seemed repetitive and that could’ve flowed better for me, and there were errors that a good editor should have caught. I definitely look forward to more books from this author though and am thankful for the opportunity to ARC read this book. This is a book you definitely want to check the trigger warnings before starting. It is packed with trauma and subjects that could be difficult for some readers. Tropes in this book include: Grumpy/Sunshine Small Town Romance Curvy Single Mom FMC Broody Hermit MMC He Falls First Touch Her & ☠️ Previous DV and offscreen SA PTSD rep

Tuesday James... lord have MERCY!! I cannot believe this was your first book, to think that you are just getting started terrifies me and leaves me on the edge of my seat! The absolute chokehold that this book has had on me... cannot be put into words. I waited for this book to be released. I saw teaser reels on IG and saved it on my TBR and patiently waited. The moment it became available I DEVOURED it! I read it in one day, and it is definitely in my top favorites of all time and I read a lot. I love a romance book that has a deeper, twisty, trauma filled plot. I like a book about people some would call damaged, (with jagged edges 😉) that have tons of baggage and are an ever evolving work in progress. Maddox and Evie had me from the jump. I have a soft spot for victims of domestic violence and all other forms of abuse as I grew up in a similar environment and when I say that this book captured and represented victims of DV beautifully, I mean it with my whole chest. I saw so many similarities in Evie that I could relate to and how she didn't want to be saved she wanted someone to stand beside her... and boy oh boy was that Maddox Wilder! Maddox is haunted by his own ghosts and after meeting Evie they bond over their pasts and push each other to be better. Evie is the definition of a single mom doing the very best that she can, and I loved every second of sweetness Tuesday shared of her adorable twin boys. I found myself thinking several times, I want to be in Evie and Louisiana's friend circle. This book is angsty, full of funny banter, suspenseful, filled with little boy cuteness/silliness and full of all the steamy good parts. Definitely read the trigger warnings, as it explores darker themes and may not be for everyone. For me this one was a 12 out of 10 and Tuesday James will be an automatic read for me. Do not even get me started on my anticipation for Mr. Mercy Wilder because do not have words. I also CANNOT WAIT for Louisiana's book, I fell in love with her instantly. Do yourself a favor and read this book, it had all the things. And Tuesday, please do us all favor and keep writing books like this one that embed in my brain and I cannot stop thinking about!! Tropes: 🖤 MMC with a Dirty Mouth 💖 Grumpy Neighbor 🖤 Possessive 💖 Single Mom (On the Run) 🖤 Trauma Bonding 💖 Curvy FMC 🖤 Found Family 💖 He Falls First (less) @ashleyheartsbooks

Evie and Maddox
Format: Kindle
Please check trigger warnings before diving in. This book was an emotional rollercoaster in the best way. Tuesday James did an incredible job crafting a story that flowed effortlessly while packing a serious emotional punch. The found family dynamic hit me right in the feels, and the backstories? Heart-wrenching. Evie and Maddox have been through so much—it’s impossible not to root for them. Their healing journey isn’t easy, but the way they lean on each other makes every struggle worth it. The side characters were fantastic, bringing warmth, friendship, and that cozy found-family vibe. And Evie’s twin boys? Absolutely adored them. Their bond with Maddox was heart-melting. Speaking of Maddox—his growth was chef’s kiss. He starts off as a broken man, using anger as a shield, but Evie cracks through that armor, bringing light back into his life. Not gonna lie, he irked me around the halfway mark, but once his backstory unfolds, you get it. Was he right? No. But he’s trying, learning, and making up for past mistakes, and I love that. Also, that man and his filthy mouth? Devoured this book the same way he devoured Evie. And Evie? Absolute powerhouse. She’s been through hell but never let her storm touch her babies. Watching her be the best mom while fighting for her own happiness was everything. I’m beyond excited for the next book because if this one is anything to go by, it’s going to be so good. What to Expect: ❤️ Grumpy x Sunshine 🖤Hurt/Comfort ❤️ "Pretty girl" 🖤 Height Difference ❤️ Plus-Size FMC 🖤Single Mom on the Run ❤️ FMC with Physical Scars 🖤Trauma ❤️ Banter 🖤MMC in Glasses ❤️ Who did this to you? 🖤Dark Small-Town Romance ❤️ Found Family Thank you to Tuesday James, the author, and the Author Agency team for the ARC opportunity!

Obsessed. Destroyed. Healed. Tuesday James’ debut is everything.
Format: Kindle
4.5 These Jagged Edges by Tuesday James is the debut that grabs your heart, gives it a squeeze, and then stitches it back together, one broken piece at a time. Meet Evie: fierce, no-nonsense, and a single mom who’s escaped her traumatic past but still carries the weight of it. Enter Maddox Wilder: broody, broken, emotionally unavailable—everything Evie should avoid. She’s everything he thinks he can’t have. But of course, they can’t stay away. This book? Pure emotional chaos—and I am HERE for it. Evie’s journey as a mother, survivor, and woman finding her way back to love? Breathtaking. And Maddox? Oh, honey. He’s the broody, big-hearted hero that makes you scream, "Let me love you!" The chemistry? Electric. The tension? Off. The. Charts. The spice? Don’t even get me started. The side characters? OBSESSED. Mercy is the flirty golden retriever we all need, Vic will steal your heart, and the twins? Pure joy. This book isn’t just a romance; it’s a found family story that will make you laugh, cry, and want to hug every single character. Tuesday, please don’t make me wait too long for Lou or Mercy's stories. I’m begging you. The writing? Lyrical, gut-punching, and beautifully raw. Every single moment will hit you. If you love grumpy-sunshine, second chances, and emotional healing that’s messy, imperfect, and oh-so-satisfying, this is a must-read. Read it. Cry. Hug your loved ones. Then DM me so we can scream about Maddox Wilder together.
