- No acoustic baffle
On more than 2/3 of the loudspeaker range there is no acoustic baffle which interferes with the radiation of the acoustic original or causes reflections.
The still remaining minimum surface is formed in such a way that reflections, which might possibly still be dreaded, are diffused and are not reflected disturbingly in their angle of radiation.
Just test with a friend how corrupting acoustic baffle reflections are. Take a carton or a board with a 6 cm hole in it and ask your vis-à-vis once to speak to you through this hole and then to say the same thing again without this board. You will immedaiately notice the acoustic difference, it is incredible how great the deviation from the original is.
A quicker test is to put both hands or two CD cases to he left and right of the mouth opening.
- Resonances
Cases should be acoustically dead, accepting no kind of mechanic stimulation.
VOICE-POINT kills no energy in the case, but has constructed one of the most stable loudspeaker cases with VP 160 A. The acoustic energy shall remain where it is - in the membrane and its radiation.
Inside the case of VoicePoint 160 A 38 complexly constructed struttings and stabilizers provide for a multiplication of stability and have an additional diffusing effect.
To eliminate still remaining minimal vibrations VOICE-POINT uses the bell-theory. The focussing of remaining vibrations and their concentrated elimination. You remember: a bell with cracks does not sound and vibrate anymore, because all energy is now transformed into frictional heat in the crack and is thus acoustically eliminated.
Similarly, the case of VoicePoint 160 A has exactly controlled 'cracks' which are filled with an extremely vibration-absorbing material and which transform remaining minimal vibrations into heat. These cracks are exactly calculated. The case consists of three parts and the connections of the individual parts represent the cracks in the bell.
- Stationary waves ...
... do not exist inside the VP 160 A case.
The form alone ensures that there are no parallel walls. Diffusors inside the case additionally provide for a diffusion of remaining energies and cause their petering out.
The robust 3-part case of VoicePoint 160 A consists of a low-vibrating aluminium-alloy and is handcrafted in the complex bell-founding technique. With the help of special optimization processes all parameters in the direction of vibration and resonance can be deactivated perceptibly and, of course, audibly.
The inside is formed by 3 case-shells, which are fabricated with bell-founding technique and are joined by a specially developed adhesive, and which simulate the so-called cracks of a bell. Inside, 38 complex aluminium-struttings provide for a multiplication of stability. These struttings precisely direct the most minimal remaining vibrations into the 'cracks', where they are transformed into heat.
As a result, all the music's sound-energy is preserved. Thus, regarding the pulse behaviour, a correct and stereoscopic optimal sound-representation, which is unequalled, is achieved by VoicePoint 160 A.
