As per the patent, out-of-band chamber resonances above 180Hz should be actively filtered out. The loading of two face-to-face woofers in a minimal enclosure increases their useful bandwidth and raises radiation resistance to lower their resonant frequency for superior cone braking power.

That's free and invisible room treatment. This avoids room modes and with it, bass that doesn't stop decaying. Destructive interference between in-phase front and out-of-phase rear radiation creates much reduced output at the sides, i.e. Their negative-going output vents out back through the two other slots of the triple-chamber frame. Their positive-going output vents through the front slot created by their mounting geometry. How does it work? Two woofers in very close proximity fire at each other. Note the change of resonant frequency between sealed box and RiPol loading, the far smaller cubic volume of the latter and its superior dispersion control across all frequencies of its bandwidth. All three models for these measurements used the exact same 40cm woofer.
8 pattern of a classic dipole in the middle, a RiPol radiates as an asymmetrical quasi dipole. Unlike the spherical radiation of the sealed subwoofer at left or the symmetrical fig. What if bass could be made more directional and without the massive DSP Kii's Three exploits?Įnter Axel Ridtahler's so-called RiPol loading, a patented dipole-evolved H-frame scheme which controls dispersion pattern, increases radiation resistance and lowers its drivers' resonant frequency, an effect maximized with smaller cabinetry. Depending on involved time delay, our ears either sum all this data into one, albeit with blurred edges and ringing or our brain processes the late signal as a ghost aka room-induced reverb/echo. Finally we hear the last reflections from the farthest boundaries. Next we hear-whatever comes first-the ricochet off the side or front walls, ceiling or floor. First we hear the direct sound which hits our ears without bounce.
That means equally in all directions so we hear it more than once. Review component retail: €3'999 with external TruAudio S500-DSP mono amplifierĭirectional bass? Low bass propagates omnipolar.
