REX is the next evolution of smart speakers in the ultraportable Boombot collection. A salute to the king of dinosaurs, the REX mimics the thump of the T-Rex’s footsteps as it ruled the land. With revolutionary acoustic and industrial design, a noise-canceling microphone and a built-in clip, the REX allows you to stay connected to your friends and your music, while keeping your phone safely in your pocket. The REX connects to iPods, smartphones, tablets, and laptops using wireless Bluetooth technology. Stream music, change tracks, and answer, end, or deny phone calls on the fly. The REX is built to withstand the demands of an active lifestyle so you can bring music to where you enjoy it most.

Ultraportable engineering that fits in your palm

The product originated from carving a clay block to find the ideal shape for the ultraportable speaker. The REX was crafted to fit in the palm of your hand, be clipped onto your backpack, belt, or handlebars and be toted on adventures with ease. The housing is a ruggedized high-impact ABS shell with the circuit board secured to the internal frame in four locations. The unit is certified IP53 water-resistant; don’t hesitate to bring it cycling in rain or on your next snow outing. The REX is powered by a rechargeable medical-grade lithium-ion battery that will keep the tunes booming for 6 hours. The industrial design of the REX encourages you to pick it up, clip it on, and add a soundtrack to your life in motion.

Modern design with unparalleled utility

As a companion device to your mobile phone, we sculpted the edges of the REX to compliment your handset as a day-to-day accessory. We chose to build something distinguished that can be discreetly integrated into your outerwear, or showcased as a beacon of modern design. In addition, the REX features fully interchangeable grills and belt clips and will come in limited edition colorways designed by renown artists. Whatever your flavor, we've got you covered.

Uncompromising acoustic performance

The sound on the REX is unmatched by any speaker of its size. With dual 36-millimeter full-range drivers and a MASSIVE Bass Woofer, the REX is the smallest 2.1 sound-system in the world. The full dynamic range of the REX is stabilized across all frequencies in the audible spectrum allowing the speaker to reach over 90 dB@2ft. The REX has optimized volumetric calculations that are matched to the driver characteristics ensuring that every square inch helps deliver the richest audio experience possible.  

Hands-free capabilities that empower and protect

The REX incorporates a noise cancelling microphone that allows you to answer, deny, or end a phone call with the press of a button. Leave your phone protected in your pocket and change tracks and volume using our custom designed firmware. Do it all with just three buttons. 

Daisy chain with SoundHub technology

The Boombot REX features Audio IN and Audio OUT ports for ultimate system scalability. Simply plug in any peripheral speaker system to the Audio Out port on the Boombot REX and the stereo signal will be replicated throughout the entire system. To daisy chain the Boombot REX, simply plug the Audio Out into the Audio In port on the next Boombot REX speaker, and repeat infinitely. The best part of it all? Control any impromptu sound system wirelessly with Bluetooth!

Siri Integration

The REX is the first ultraportable speaker with Siri integration.  Queue a request to Siri with the push of a button and Siri will answer back to you through the speaker. 

What we need to bring the REX series to life

We've invested in the research, design, and development of the product. We've even invested in the tooling to build this incredible piece, but we need your help to get the first pilot run of the REX to market.  We are looking to Kickstarter to raise at least $27k to fund our first low-volume production run.

We are grateful for your support. We're proud to offer our backers with:

THANK YOU Kickstarter for allowing us to continue following our dreams.  Now that you have sweetened the deal for us, we want to give a little something extra back to you.  We made these mini-cube shaped travel chargers that you can use to charge anything via USB including your new Boombot REX or your mobile device.  Each charger features a soft-touch coating and folding plugs so you can stay juiced up wherever you go.  

The Story

Boombotix was founded by Lief Storer and Chris McKleroy - two college friends who met on the ski slopes of Lake Tahoe, with a passion for music, gadgets, and the active outdoor lifestyle. Lief, an optical engineer with a background in fiber optic lighting systems, created the first Boombot ultraportable speaker in 2009. Developed as an alternative to headphones, the Boombot was conceived by combining a Japanese vinyl toy, off-the-shelf speaker internals, and a walkie-talkie clip. Originally developed for a bike ride to work, both founders quickly realized that this product integrated perfectly into their life off the saddle as well. Chris, with a background in marketing and product design, began to sculpt the first Boombot REX prototype in 2011. With support from friends, advisors, and the growing team at Boombotix, the Boombot REX project began to take shape and evolve into the product you see today. 

Engineers + Audiophiles

Our team has been building ultraportable speakers for years now and we have experienced the pleasure and pain of hardware.  Lief Storer heads the electromechanical design leveraging years of experience developing high-power intelligent fiberoptic lighting systems.  Chris McKleroy was instrumental in the original concept and design of the REX, and continues to be involved with the manufacturing and product management process.  Ben Radler flexes 16GB of RAM lodged in his cerebral cortex to undertake the task of iOS and Ruby development.  Ben is building technology that will expand the potential of the REX with a mobile app that allows audio mesh networking. 

Our crew now consists of seven people crammed into a studio-loft-garage in San Francisco's Mission District.  There is never a silent moment in the office, especially when you have round-the-clock R&D on a speaker system loud enough to fill up the whole room.  At least it sounds amazing because we wouldn't have it any other way. 

Everyone on our team has at least an 18-inch vert.  Fact.

SIZE REFERENCE

We have spent the last 15 months fine tuning the industrial design and the electromechanical engineering of the Boombot REX in our SF-based live-work-garage-studio loft.  We have been creating speakers for over two years with our trusted contract manufacturer in Shenzhen; we have gained many production efficiencies and learned about a number of production faults to look out for after shipping thousands of Boombot speakers. After six rounds of prototypes, The Boombot REX unit has been tooled and we are currently testing our T1 (first unit off the tool).

Pending the success of our Kickstarter campaign, we will begin production on the first round of units on December 31. We have sourced the materials for the first 3,000 units to be ready for this first production. These units have a 30 day lead time (production time).  We will take an additional 10 days to do a final inspection and QC of all outgoing units.  It will take another 24 days to ship across the Pacific Ocean leaving from Hong Kong and arriving in Oakland, CA. Units will be shipped via USPS ground from the Bay Area once landed.  We use a fulfillment center in Vacaville, CA which has the capacity to ship hundreds of boxes with a 48 hour turnaround. Between production time (30 days), final inspection and QC (10 days), and shipping from Hong Kong to Oakland, CA (30 days), the Boombot REX should be shipping out of our fulfillment center in early March.

Pending success the success of our campaign, beginning January 22nd, we will be able to produce 5,000 units per month with our current factory in order to meet demand. Units will have a 30 day lead time (production time), 10 day quality control/inspection,  and a 24 day shipping transit time. Units will be shipped to backers in order of project funding date. 

Risks and challenges Learn about accountability on Kickstarter

Hardware is hard. But we love it. As we mentioned, we've swallowed one of the most daunting tasks in product development (tooling), but there are certainly some potential bumps in the road that we're prepared for.

One of our biggest struggles on this project was power management. We aimed for such a compact form factor that there is limited space for anything. Hitting our target runtime has continued to be a struggle, but we are working on engineering a more efficient amp design. Some of our more recent tests seem much more promising, but there is still a lot of work to be done to deploy this design into production.

The REX pushes the upper threshold of what the speakers are capable of. There have been a number of improvements with integrated signal filters to alleviate issues with clipping and distortion. Digital music these days is chalked full of a wide variety of quality standards. This has resulted in a daunting variable that makes it difficult to deliver consistent sound quality from inconsistent signal levels. It is something our team would like to continue investing our time in improving, but for now, we'd encourage you to avoid crappy recordings whenever possible. After all, YOU are an audiophile too right?

We've worked with our ODM in China for several years now, which alleviates a number of risks associated with outsourcing. That's one less problem to worry about. This doesn't mean that we can relax, but we know that our challenge with them is to get them to produce exactly what we spec. Any first run product is more at-risk of falling off of spec, so we have to pay particularly close attention to getting it right the first time around, managing our risk, and ramping up production gradually. We've learned the hard way before.
