Since the launch of the WLA-28 line array, people have been expanding their systems into monster-sized rigs. As these rigs have expanded, the demand for even more bass has also increased.
The new WLA-28SUB now delivers that enormous bass for larger WLA systems – all in a physical enclosure that fits perfectly with flown or ground stacked WLA-28 systems.
With DUAL 15” Wharfedale Pro drivers boasting 4” voice coils, the WLA-28SUB is capable of 145dB and handles peaks of up to 4800w.
Ground stack or fly
Using the optional WLA-28SUB fly frame gives system versatility.Fly the WLA-28SUB at the top of the array along with up to 12 units of WLA-28 with a safety factor of 12.Alternatively, ground stack using the WLA-28SUB Fly Frame
Dual 15″ LF transducers
The dual 15″ LF transducers are mounted inside the cabinet in such a way to maximise the low frequencies while keeping the physical cabinet dimensions to a minimum.
Huge voice coils
The 4″ voice coils ensures massive power handling.The WLA-28SUB can handle peaks of up to 4800w and programme material averaging 2400w.These custom Wharfedale Pro 15″ drivers are efficient and powerful – delivering the sub-bass punch needed for larger gigs and impressive installations.
Strong internal bracing
With so much potential air movement, the cabinet of a subwoofer this size must also be incredibly robust – both externally and internally.The internal bracing of the WLA-28SUB has been carefully designed to avoid any vibrations or shape distortions during high volume use.Using 18mm plywood the robust cabinet is ready for whatever the bottom-end needs.

The best personal finance book I’ve ever read.
Format: Hardcover
Most finance books focus on the mechanics—budgets, tax strategies, portfolio construction, and the endless parade of acronyms and formulas. Those things matter, of course. But they miss the real issue.
Money problems are rarely mechanical. They’re behavioral.
That’s where The Psychology of Money stands apart. Housel goes straight to the heart of the matter: how people think about money, how emotions shape financial decisions, and why intelligent people still make poor choices with their finances.
The book doesn’t lecture you with formulas. It speaks to you. It speaks to your brain—the quiet assumptions you carry about wealth, success, security, and risk. It forces you to confront the uncomfortable reality that managing money well is far more about temperament than intelligence.
One chapter that especially stood out to me is “The Seduction of Pessimism.” Housel explains why pessimism often sounds smarter than optimism. Doom and gloom feel analytical and sophisticated, while optimism can sound naive. But over long stretches of time—especially in markets and economic progress—optimism tends to be far closer to reality.
It’s a beautifully written chapter and an important reminder for anyone who spends time around financial news or market commentary.
What makes this book exceptional is its clarity and humanity. Housel understands that money isn’t just math—it’s tied to ego, fear, status, insecurity, and hope. And until you understand those forces, no spreadsheet or strategy will save you.
If you read only one book about money, make it this one.

Great book
Format: Paperback
"The Psychology of Money" by Morgan Housel is a thought-provoking book that explores the complex relationship between money, greed, and happiness. Housel challenges conventional notions about wealth, arguing that it's not just about smart decisions, but also about behavior and psychology ¹.
The book is divided into 20 short chapters, each tackling a different aspect of money psychology. Housel uses engaging storytelling and real-life examples to illustrate his points, making the book an enjoyable read.
One of the key takeaways from the book is the importance of understanding your own values and priorities when it comes to money. Housel argues that money is a reflection of our values, and that our financial decisions should align with what's truly important to us ².
The book also delves into the power of compounding, highlighting the benefits of long-term thinking and patient investing. Housel emphasizes that getting wealthy slowly is often a more sustainable and reliable approach than seeking overnight success ².
Other notable themes in the book include the role of luck in financial outcomes, the dangers of complexity in financial decision-making, and the impact of stories and narratives on our financial behaviors ².
Overall, "The Psychology of Money" is a insightful and accessible book that offers valuable lessons for anyone looking to improve their relationship with money. As one reviewer noted, "This book is the book I wish I had read when I was young" ¹.
*Key Takeaways:*
- *Money as a Reflection of Values*: Understand your own values and priorities when it comes to money.
- *The Power of Compounding*: Long-term thinking and patient investing can lead to significant financial gains.
- *The Role of Luck*: Recognize the influence of chance and unforeseen circumstances on financial outcomes.
- *Simplicity over Complexity*: Avoid complex financial decisions and focus on simplicity and clarity.
- *The Impact of Stories*: Be aware of how narratives and stories shape your financial behaviors and decisions.

So Adorable! Thicker Paper and Fun to Color!
Format: Paperback, Format: Paperback
The Coco Wyo team has done it again! Another super cute coloring book filled with the cutest characters! The paper is thicker than in previous Coco books, yay! but if you’re using markers you will still want to put paper behind the page you are coloring. Ink bleed through still happens but not as much.
Shading:
If you want to add shadows on top of the marker areas, the Prismacolor premier soft core colored pencils work beautifully, but be sure to let the paper dry completely first.
Update Review Regarding Marker Blending:
With the thicker paper you can get away with many rounds of normal blending techniques with both alcohol markers. See the photo of mine with the shooting star. That page has so many layers of marker blending that I lost count, haha and the paper is still in tact! Yay!
Creating Highlights:
I use Sakura gelly roll pens as well as acrylic paint pens for highlights with no issues.
Pro tip: If you’re using gelly roll pens, be sure they are bold 10. That will fit the scale of the art on the page and it won’t get clogged during use.
Coloring Tools:
I’ve tried using:
Copic alcohol markers
Tombow water based markers
Ohuhu alcohol markers
Kingart water based markers
Kagito alcohol markers
Prismacolor Premier Soft Core colored pencils
Sakura GellyRoll Moonlight Bold 10 Pens
Shuttleart Acrylic paint pens
Everything has worked beautifully and I've been able to successfully achieve nice shading and blending.
Note: All of the coloring tools I’ve mentioned above can be found and purchased right here on Amazon.
I own lots of Coco books and love coloring in them. Their illustration style is calm and friendly, making coloring in them a relaxing and enjoyable experience. There were only a few pages in this book that I would not find enjoyable to color such as the holiday themed pages. I wish they wouldn't always put holiday themed pages in non-holiday books, but they can easily be removed if you want and this book really only had a few, so still worth purchasing in my opinion.
You can tell much thought and care went into creating illustrations that would be fun to color while also helping to reduce stress, which is one of the things we all in the coloring community love about coloring right?! Coloring in Coco books is such a fantastic way to reduce stress and their designs are top notch.
A highly recommended coloring book for all ages! I hope you found this review helpful!
