The LD130CR04 is a midrange bass speaker designed for the realization of a 2-channel system of very high quality in a small footprint.
It is equipped with a paper membrane combined with a peripheral suspension technology LDS ™ characterized by a very specific profile limiting the phenomena of parasitic reflections and standing waves at the mouth of the cone.
The corehas a copper ring which substantially reduces the distortions by third-order harmonic by canceling the creation of induced currents in the pole pieces.
When listened to, these specificities result in an absence of projection phenomenon and a medium register restored with softness and precision.
EIn addition, the low resonant frequency and the high excursion capacity make it possible to obtain a high acoustic pressure in the low frequencies.
