An open baffle speaker with good field coil drivers sorts out typical issues with low frequency control. In my listening, the only traditionally boxed speakers able to eliminate cabinet colouration have been the massive kharma enigma veyrons and the goebel divin marquis, and even so, never fully - a nuanced degree of cabinet is always heard. Something about greatly increased size, i believe, reduces unwanted sound contributions of the sealed box design. Open baffle, all other things equal, comes without any trace of colouration whatsoever, coupled with all that air which accompanies live music. They’re simply amazing : )
