It should be an optically extremely slim floor box. We solved the problem by making the box a bit higher to still get the volume needed for the bass in the box.
Two Markaudio CHR-70 were used. To avoid comb filter effects in the treble (directional extinction by two sound sources), the treble is generated by a Wavecor tweeter.
Explanation: Two sound sources in the highs are fundamentally problematic, since at 20 kHz the wavelength is only about 1.5 cm. If one of the two sources 0.75 cm (half wavelength) is closer than the other, so there would be by the 180 degrees rotated phase in the direction of the listener virtually complete extinction, which of course may not be.
In the crossover, a second-order low pass drives the broad bands. The Wavecor tweeter is controlled by a 3rd order high pass.
In order to provide the room with the same amount of energy, independent of frequency, Beni exaggerates the highs a bit on the axis. At 30 degrees, its frequency response is exemplary straight and is very low for a small slim box.
Explanation: With increasing frequency, which is radiated by a loudspeaker membrane, this bundles more and more. When the room reflects, the highest frequencies that a membrane emits are radiated at a narrow angle. These frequencies are emitted with too little energy if the loudspeaker on axis has an exactly flat frequency response. It is therefore a common method to tune the speaker so that it has a flat frequency response at 15 or 30 degrees angle, so that frequencies that are too weakly radiated at larger angles, then slightly exaggerated on the axis.
