The Z series is the result of our ongoing study in the field of world sub woofer domination. The Z project represents the culmination of DD′s ultimate engineering goal which is to push the limits of delivered energy by utilizing high performance composite technologies. The Z series takes it′s place as the flagship of the DD sub line by having the highest motor strength, greatest voice coil cooling capability, most overbuilt design features, and last but not least True To The Source sound reproduction. AmaZing! The Z series represent the pinnacle of transducer archeology. The unique design dates back to the precocious era of unequivocal magnetism and the vector planar research of underwater acoustic proliferation. The open archeology concentrates flux lines in the magnetic gap while side lobbing interference cancels stray flux from entering the atmosphere. The result is increased efficiency over the entire bandwidth of collaborating bass frequencies. This allows the Z Series woofers to play amazingly loud with little wasted energy being dissipated as unwarranted heat, this means they get on it and don′t get real hot. The Z Series breaks new ground in rare earth magnetics, using newly discovered material, neo-demetrious iron proton (Ned), incalculably more strenuous than the other discovered rare earth magnet material. Ned is highly unstable and very difficult to modulate, yet alone saturate, so its use is mainly limited to noncommercial phase generators used in anti-matter plasma generation. Digital Designs has acquired the rights to use Ned magnetics in non-military acoustic weaponry and the peaceful development of humanistic cohesion through harmonizing wave generation. The unstable Ned blocks are held in symmetry by the side lobe interference which allows the use of the catchy monolithic block shapes from that cool 2001 space movie. These are spatially arrayed to over saturate the Permendur top plate imported from Switzerland, from one of those really beautiful, lake filled mountain valleys, giving huge magnetic energy to drive the voice coils. The moving parts of the Z Series have undergone a minute amount of scrutiny also, the cones feature newly contrived composite materials to handle the extra load lines emulating from the motor, the voice coils are spiral wound in reversing layer directions for optimum efficiency and the voice coil former is really strong. The combined technological oeuvre nearly eliminates all chance of spurious effluvium from occuring. The spiders also feature new technology never found on arachnid based suspensions, silkaleneotton. Genetically altered spiders produce a chemical blended thread of silk, polyethylene and cotton. This synthetic blend is superior to our other synthetic blend. The new synthetic blend is stronger than standard arachnid fiber, more flexible than polyunsaturated polyethylene, lighter than water (it actually floats) and yet so soft and comfortable. This material can stretch to 1.7 times its weight, allowing for un-presidential travel. The new Z Series woofers have more Watts than any speakers we have ever built, so many Watts they got, that we thought of using a new slogan, Got Watts?, but that′s lame so we didn′t. We tried to measure the exact amount of Watts a Z Series put out, but all we got was dBs.
