Why is our speakers flat?
The principle we use in our Chameleon models is named open baffle. There is no box which alone in a acoustical sense can not work properly. Because if you take a standard cabinet speaker and remove the box the bass will disappear. It disappear because bass signal is (mostly) distributed like ball - it is not directional. The effect is that the low frequency front wave will travel to the back and opposite for the backside wave. This equal a cancelation of the bass so it is missing.
In the first days of dynamic speakers most was placed in a corner. When the technology became more affordable and went into be a luxurious consumer product the need for a more indoor friendly design was needed. At that time we didn’t have any measurement equipment, computers or could put exact scientific words on what happened electrical and mechanical in a dynamic speaker. We didn’t know exactly what happened if we change some of these parameters.
Today we have a lot more knowledge and can design the drivers so they fit exactly in our application. We also have a lot more knowledge about acoustics so we can design the speakers the way we do.
Why do we then design a open baffle and not just another cabinet speaker. Well just another speaker is not our game. And it is not our game because and open baffle or dipole design simply sound several times better than a cabinet speaker. They are also cost effective and typically easy to drive. There is equally good sounding cabinet speakers but you have to pay a much higher price. It sounds all positive right? But is there down sides so to speak? We think not but some will say that the our dipole speakers will not fit in there home because they need to be a bit away from the backwall. That also count for a cabinet speaker. And compared to a cabinet speaker so is a dipole less interactive with the floor, ceiling and sidewalls. Some also think that it is dangerous with exposed drivers - it isn't. So what would you choose then?
Another difference is the reproduction of bass and mid frequencies - since no box no box sound like you typically find in a cabinet speaker. The bass and mid sound reproduction is clear and detailed. It match the open transient sound from the other drivers. One thing you can not expect from a open baffle is deeeeep subsonic bass. This will need a very wide baffle. If you can‘t live without that then you can always add an active subwoofer.
