The letters «B» and «R» clearly indicate the type of design – phase inverter (Bass Reflex). If it were not a strong knowledge of foreign languages, slotted port along the lower wall of the shell might not notice. This is the most difficult subwoofer, the box itself rather bulky, although not the largest in the class.
And since the wall he has a standard thickness, is to recognize that the rest of the weight recruited by a solid head E-Type. So the developers did the right thing, that have provided a window overlooking the head, but at the same time the blue light: four superbright LEDs with reflectors shine on the head, like a searchlight on the Arc de Triomphe.
The angle of the rear wall (15 degrees) closest to the canonical 20 degrees. The design provides for protection of the diffuser in the form of a pair of straight arcs. Clamping screw (located on the rear), they are large, and perhaps most comfortable in today’s group.

Schedule impedance characteristics shows that the resonance frequency head 63 Hz, and fazik set to 40 Hz. Now, if we turn to the frequency response can be seen that the peak sound pressure level (bandwidth 40 Hz) just to the frequency settings of the port. Be pokompaktnee box, the frequency response would be more relaxed form, but I think it was a conscious choice of authors develop – usually fazik choose not to those who need a quiet, academic bass.
But the sensitivity of this subwoofer is higher than that of all the “colleagues”. Yes, and the maximum sound pressure close to him he did not let any of the competitors. With the growth of forward power is beginning to affect the thermal compression in the head. By the way, when the fixation of this fact, we were served at the E-Type as many as 1 kW of power (+30 dB of voltage).
