MY STORY

When I was 12, I built my first speaker out of a shoebox. It sounded terrible but I loved the process of building my own stuff. Flash forward to 2010 and my career as a location sound mixer. I needed a portable, yet very rugged battery powered speaker and I had no choice but to make it myself out of one of my equipment cases and found parts. It was a hit with the crew and suddenly I had requests to build more.  

The DemerBox was created out of need because there wasn't anything like it on the market. Its taken years of prototyping and real world testing to create a boombox that sounds amazing, can travel anywhere with you and will last a lifetime. And you can put stuff inside it which makes it even better!

By supporting our Kickstarter campaign you'll be helping us to pay for the very expensive process of injection molding the parts we've spent years prototyping and perfecting. You will also help us pay for manufacturing our printed circuit board. The PCB is the heart and brains of the DemerBox and after hundreds of hours researching, testing, building prototypes and pre production PCB's, we finally have it just right.

What is a DemerBox?

 DemerBox is a rugged, great sounding, water-resistant boombox that you can put things inside.

The Bang is our single speaker model. Its about the size of a lunchbox but don't let its svelte size fool you. The Bang gets loud, has tight punchy bass, and pleasing mids and highs. 

The Big Bang is our two speaker model. Its about the size of a soccer ball. The Big Bang gets louder than The Bang, and because it has two speakers, you get stereo separation and a little more detail in the music.

Why choose a DemerBox?

SOUND QUALITY

Our full-range speakers create a purity of sound that multiple speaker systems can rarely achieve.  DemerBoxes are acoustically tuned for incredible fidelity and punchy bass.

INCREDIBLE BATTERY LIFE

We left a DemerBox outside in a snowstorm for 24 hours to demonstrate its battery life and cold weather capability.  The audio you hear is from the DemerBox you see in the video - and you can get up to 40 hours of play time at normal volume.

 WATER RESISTANT

Every DemerBox is dunk tested before it leaves the shop.

Insert the PORT PLUG when you need to keep water out.

What's New with DemerBox?

A first look at the redesign that we're launching here on Kickstarter.

 SPEAKER GRILLES

Our new speaker grille gets a modern twist on the old retro design.  

INTERIOR SETUP

Interior components of the DemerBox are all housed in the lid, which improves durability and leaves you with more space for storage.  The prototypes shown above are clear - the housing on the DemerBox you receive will be black.

USB CHARGING

 We revisited our circuit board design and added USB charging for all compatible devices.  Now DemerBox can charge your... whatever.

THE POWER SWITCH 

With all the components housed in the lid, we developed a new waterproof switch with a green LED that is made in the USA.

THE SUPERNOVA 

This is one big DemerBox reward. We started with a USA made Pelican 1620 Case, and put some 8" full range speakers in it. Its ported, and will come with custom CNC routed ABS speaker grills, an integrated amplifier that is sized appropriately, Bluetooth (and 3.5mm stereo mini jack) and a big Lithium Ion Battery. This is a working prototype and will sound great and get loud.We're currently only building one of these for a very special DemerBox Kickstarter reward.

This is NOT Photoshopped. This is a real, really big DemerBox.

Grain Surfboards and DemerBox collaboration

The Grain Surfboards crew and DemerBox are collaborating to build a beautiful, hand crafted wooden surfboard with the components of a DemerBox built into it. This will be a boombox surfboard that can actually be surfed and will actually play music. It will be this board with speakers artfully integrated into the deck of the board. You'll be able to listen to music while surfing or just hanging out after your session by linking your phone via bluetooth or connecting with the built in waterproof stereo mini jack and custom cable.

This reward combines two Maine companies that value using the best locally sourced materials and craftsmen to create a very special one of a kind object.

For times when you're not surfing and you want to display this board/boombox, we'll include your choice of a floor or wall stand.

All DemerBoxes are assembled by hand with love in Portland, Maine USA. Each DemerBox is dunk tested in a fish tank and the electronics are fully tested before you receive it.

Water resistant until submerged in water deeper than 1 foot (30cm) or for 1 minute. If you exceed these parameters we cannot guarantee your DemerBox will remain waterproof.

Warranty: Parts, labor and shipping (in the USA) are guaranteed for 1 year from purchase. If we determine that the problem is the fault of the user, you will be responsible for paying for the shipping and repair.

Battery: Either a 2200mAh Li Ion or a  4400mAh Li Ion. Up to 40 hours play time between charges with the 2200MaH battery, or up to 90 hours play time with the 4400mAh.  Tested at an average of 75db at 3 feet (1 meter) playing a variety of music, hardwired.

Average time to charge from depleted battery to full: 4 Hours

Battery Charger: 120-240v AC input. 1000mAh 12.6v DC output, center pin positive.

Risks and challenges

We've built DemerBox from the ground up and tried to minimize risks at every step along the way. We've been circulating and testing prototype models for more than a year to make sure that the product we're offering is the one you'll receive.

With our redesign, we're bringing on two new vendors which we carefully worked with our team of engineers to select. We are confident in their ability to deliver quality parts on our firm timeline, and we're working with them to ensure that production runs smoothly on the schedule we've laid out.

As with any new product, there are inherent risks of delay. Should we encounter any hiccups, which we don't expect, we will communicate with our backers and ensure that fulfillment is as close to our published timeline as humanly possible. We've been known to ship product overnight, stay up all night and all weekend working, drive and fly to solve problems in person. We probably won't have to do any of that, but our team is almost as hard-working as the DemerBox is tough.

This very special DemerBox will have an appropriately paired amplifier, Bluetooth, a big battery and custom CNC machined ABS speaker grills.
