Well put. We agree that the user's manual could use some more depth. We certainly are not hiding anything but I hear what you mean. We're listening and improving all the time.
I've got to challenge your thinking on one thing though. You said:
Why is there no spec sheet? Everything else includes spec sheets: freq. response, watts, amps, distortion...
It turns out with an L1, creating a Cyldrical wave front these need to be measured differently and addin them would only add confusion. It's kind of like measuring gas in meters ... it isn't helpful.
Another thing about specs is that they can be true and lie at the same time. For example, Watts don't matter. How loud is a 40W light bulb? Is it louder than a 5 W halogen bulb?
Also, if you measure peak output at one location what about the others and at what frequency and is the speaker flat over that range and on and on. So, we stay away from specs because 99% of people are not better informed by specs than they would be by just lisetning to the speaker.
I know you may disagree with that, that's fine. But I know how to read spec's pretty well and I don't trust them. I use my ears.
Thanks for the feedback and we will look into making improvements. I appreciate you giving us "actionable" feedback.
