Still hazy on Ripol? Perhaps pictures talk better. This Klippel balloon shows how unlike conventional omni bass which renders the entire outer sphere red, dipole's 'figure 8' radiation results in quick off-axis signal drop and virtually no signal at 90°.

Whilst Magico would proudly show us how their heroic cabinet builds resist flexing to remain inert, sealed/ported bass still emits 360°. Here overkill rigidity makes no difference. Like dropping a rock down a well, ripples rush outward in all directions then reflect off the first obstacle. Such bass we don't just hear once. We hear it multiple times, first its direct line-of-sight parts, then late-arriving ricochets bouncing off floor, walls and ceiling. It's a mess in the time domain which our ear/brain sums into a blurred unity. Audiophilia which doesn't know better calls that warm, dense or powerful bass.

Another way to avoid omni bass are in-wall woofers. They can only radiate forward into half space. Their output can't wrap around to radiate behind them. Hello infinite baffle. Higher freqs instead radiate ideally from one infinitely small point in space and suffer no diffraction. Hello point source. It's where treble clef's spherical enclosures à la Anthony Gallo enter for their midrange and tweeter pods whose tapered tubes recall Laurence Dickie's work for B&W's Nautilus now Vivid.

But first, a visual on M's resonance behaviour from 10-250Hz without any low-bass EQ boost.

The next graph shows the overall system's group delay.
