Composite diffuser with a curved line, smooth rolling in the entrance central dome, we have not seen before invoice surface-as if from the incisor teeth turning machine.What is the engineering idea is not aware, but made cool.  As relies on the dynamics of this price and with this design power (300 W continuous, 600 W at peak), frame-cast, with developed ribs, addition of the signal to the voice coil with a screw-off, "and" exhaust ventilation voice coil - smooth aerodynamic shapes. For options SP-W120 close to the wagons, but with a few private boxes. Trends are hard (Vas = 85 l), and there is every reason to expect its success in small quantities.
Liberal manufacturer recommendation: 0.5 - 0.85 cu. ft., which is 14-24 litres, were surprised at just formally, but in a rather interesting option. We get that from the calculation of the optimal smooth run in a big car is 23 litres, which is almost the most recommended. In smaller values of ACHH provalivalas markedly below 80 Hz. But if SP-W120 placed in a closed box, a total of 17 liters, and then this box in a small saloon car, a few bulging before run at the lowest frequency (which sound a bit, and before handling dynamics because of a amplitude-shift hand file), a canonical horizontal from 70 Hz and below. Even handy: a car-box more, small-space. It is noteworthy that even at 17 or complete dobrotnost system does not exceed Qtc = 0.8, the compactness is not at the expense of accuracy impulses.
 
Nakamichi recommends BUGERA version of its design performance, even in two versions: with the case of 35 or 50 litres. The second option, in our view, suitable mainly for high levels of noise, and noise is produced Zaporozhets, in any cabin. A first can even make a little kompaktnee, skin up to 27 litres in constant frequency settings (33 Hz).In a large salon pieces such otygraet "with gorbikom", but relatively small, but a small wave would hefty, so that melomanskogo options do not.
