LEEDH E by Acoustical Beauty | リード E The LEEDH E loudspeaker offers the same spirit of performance than its sister, the LEEDH C, but it adds a very natural reinforcement in the bottom of the spectrum. Thereby satisfying music lovers who own large listening rooms (beyond 25 m²). The LEEDH E allows to obtain more pronounced "physical sensations" on the lower octaves, without losing its intelligibility in this domain of competence. Moreover, as music lovers know, the increase in one end of the bandwidth has inevitable repercussions on the other end, in terms of harmonic richness. Therefore, compared to its little sister, the LEEDH E deploys a high register just as accurate, but with fluidity and a delicacy further improved. Description : The LEEDH E is an enhanced version of the LEEDH C whose organs have been specifically described in the corresponding paragraph. Therefore, in this part, we shall concentrate ourselves only to develop the specificities of the model E. The LEEDH E is equipped with seven ABD (Acoustical Beauty Drivers) transducers implanted in a unique vibration-free architecture. For bass reproduction, four of these modules are coupled back to back (push-push configuration) and radiate orthogonally to the listening axis. The first of these two pairs is located a few centimeters from the ground: it takes the vertical stand in sandwich. The second is placed at one meter above the ground. Thanks to the specific structure of its bass section, including the implementation of the module devolved to lower frequencies, radiation is optimal, and LEEDH E cleverly uses the floor as a natural reinforcement. Due to the addition of the fourth module, the difference in the perceived sensation of the bass, between LEEDH C and E, results in very precise figures. In moving from C to E, there is indeed four times more energy between 20 and 40Hz and twice between 40 and 80Hz These figures merely illustrate the ability of E to operate in larger environments and on music programs much more charged in the lower register. Their additional reserve in available acoustic power guarantees that. When using it, you clearly notice a reduction of the effect of "comb filter" between 100 and 1000Hz. This effect is the direct result of the superposition of the direct wave and the reflected wave on the floor causing phase opposition at certain frequencies, and therefore "holes" in the bandwidth. This phenomenon is present on any speaker that emits at a listening height of 1 meter. With LEEDH E, the reduction of this effect results in the preservation of a sound image true to what the recording engineer desires. The transducer placed near the ground cleverly fills much of the "holes" of the bandwidth. Therefore, from a purely objective point of view, the sound reproduction of LEEDH E is more materialized, this density gives the listening experience an even more realistic sensation. To optimize this parameter, a very gradual filtering of the lower modules integrated in the stand, ensures minimum phase shift. Hence a perfect merging of registers, which ensures consistency and uniformity over the entire bandwidth. Use : The LEEDH E is intended to be used in a living room with an area equal and greater than 25m2 without any problems. Its lower register is amply able to develop there and flourish. In addition, thanks to its very linear impedance curve, the LEEDH E is less requiring from the amplifier, particularly in terms of stability on the load, and intrinsic power. It is therefore easy to marry it with balanced, musical but not necessarily very expensive integrated amplifiers. Thus, with E, it is possible to compose systems of an excellent price/quality ratio. This is an opportunity that is far from obvious with high-end speakers, often dependent of exclusive installations.
