Message from Ken Jacob

The following is a message from Ken Jacob, one of the two originators of the L1 research project.

On October 15, 2003, Bose introduced an entirely new approach to live music amplification.

At the time we launched, I can honestly say that while we were utterly confident through our testing that the benefits we were claiming were real, we just didn't know if musicians would want to try it, much less spend their hard-earned money for it. I literally lay awake many a night in the days, weeks and months leading up to our first press event on October 15 wondering if anyone was going to buy even a single L1 system.

Not only was my anxiety unfounded, what's happened has surpassed even what we allowed ourselves to dream when we were alone and thinking about how profound and positive the changes were we were observing in our live music tests.

In the past five years many tens of thousands of musicians in over one hundred countries have purchased one or more L1 systems. And what they have said about the differences owning an L1 has meant to them now constitutes an avalanche of positive evidence -- much of it here on this online forum.

The L1 approach is what I would call radical. Fundamentally, it replaces most or all of the amplification equipment that evolved in the last half of the 20th century. It replaces triple systems (PA, monitors, backline) which were found in our research to be at the heart of the persistent and acute complaints from musicians and audiences alike about the sound of live amplified music, with a simple, naturalistic approach that is more based on the evolution of unamplified music than the ever-louder, ever more complicated, ever more isolating amplification systems that evolved in the last 50 years.

In the history of hi-fi, as a parallel industry, I can think of no technology that is as radical. That is why we felt it was possible to call the L1 approach an entirely new approach.

The fact that musicians around the world, including most of you, were willing to cast off years of refinement in triple systems -- and more pointedly, attempt to cast of the problems that never went away no matter how much more sophisticated the gear became -- is for me an extraordinary story of courage and daring.

The fact that you did this, and that the results as written here and elsewhere, and on the delighted expressions of audience members, is something that I will treasure forever. It is something that I literally think about every day of my life, and will think of every day for the rest of my life.

Thank you, from the bottom of my heart.

We'd like to take the opportunity afforded by our 5th anniversary to share with you some of the things that occurred in the ten or so years of work that preceded the launch, and also some of the things that happened as we launched, and as this community started to build.

Many of my colleagues will contribute their part of the story.

We also invite you to share any of your experiences that you feel could contribute to recounting and recapturing some of the early history of the L1.

It is hard to believe that such a radical new technology has done so well. When I scan for similar successes of something so radical succeeding so much in such a short time, I come up with little. The Fender bass comes best to mind. Just imagine what it will be like to write the 10-year story of the L1.

With love, admiration and appreciation,
