Fugoo XL - frequency response measurements (Patreon)

Measured outdoor with and without sport jacket. The jacket was already modded with a thinner material, otherwise the original sport jacket would reduce treble even more. Also visible is some impact on mids and upper mids when playing inside the jacket creating some additional resonance above 1khz.

Back and front side measure quite similarly, when measured from the side treble loss is significant despite the 360° omnidirectional sound  claims. Despite the treble boost visible in the naked core measurement, interestingly the speaker still sounds slightly muddy in real life, especially when listened off axis.

Second measurements show the difference bewteen indoor and outdoor mode. Outdoor mode simply boosts the entire part above 100hz by about 4dB resulting in an overall higher maximum volume as well at the cost of some stronger bass loss and distortion compared to indoor mode.
