Music is a vector of emotion. Emotion is created by the harmony and rhythm of the music. Emotion is our target. The form was not our leit motiv but the quality of the execution. We admit that we were not really concerned about how the speakers would fit in your living room, we were rather guided by the way the speakers would sound in your living room. Ipanema is indeed a big loudspeaker but its size is necessary to reproduce low frequencies lower than 35 Hz. We understand that the size can be important, so we created the static bottom and the feet of gravity which will find their place in any interior. Its 2-way coaxial driver produces perfect tonal balance and realistic dynamics. It has the precision of a studio monitor. The gravity feet are adjustable to ensure that each speaker is set to the perfect level.
Feet of gravity
Since the music is a superposition of sine waves, it means that the energy is diffused in iso-dynamic because the force that pushes the driver of a loudspeaker is equivalent to the force that pulls the membrane of the loudspeaker . The control must therefore be searched in the horizontal rather than the vertical plane. Man has the gift of speech and is therefore able to communicate knowledge and to come back to what others have imagined in response to the problems they have faced. For a long time, in the field of electroacoustics, certain principles concerning speakers have been considered a necessity, such as their design to be heavy and inert. It was quickly realized that it was a poor apprehension of the energy generated by the acceleration of the acoustic membranes. In order to evaluate what the acceleration generates in terms of energy, you have to remember when you were listening to vinyl records. A few years ago, we experimented with numerous tests and configurations: at one point, having an inertial platform (essentially a large cube of concrete of -1 m3) dedicated to the measurement of extremely fine doses, we had the idea of placing a platinum on this platform. The turntable did not have a vibration absorption device. There was not felt under the disc but a ceramic disc, not in suspension but in direct contact (glued with glue without film) between the bearings of the turntable plate and the inertial platform. Eight high-definition accelerometer sensors were placed around the base of the inertial platform isolated from the ground. The sensors were connected to Audiomatica (specialized software) which analyzed the energy, if any, produced by the tone arm needle by applying a 1.5g force to the groove of an engraved plastic disc rotating at 33 ° C. rpm).
Imagine our surprise when we discovered that the simple reading of the furrows of the disc made vibrate the inertial platform! The eight sensors had detected energy. In fact, the amount of energy generated by the needle on the vinyl record was enormous. Years later, when we embarked on the design of Ipanema and Babel, we wondered how a speaker would react to the (often rapid) movements of speakers when they play music. The standard solution was to create a very heavy speaker that would be connected to the ground with peaks supposed to act as a mechanical diode and as a jack. "Diode" because the energy generated by the speakers goes only to the tips, and "jack" because the amount of energy that accumulates at the base will be proportionally concentrated on the tips.
