Short answer: the Radiant Acoustics Clarity 4.2 for bass in a small box, the Totem Kin One for easier drive. The Clarity 4.2’s 4” Purifi mid-woofer, matching passive radiators and AMT tweeter buy bass extension at the cost of sensitivity: rated 78dB and measured 78.5dB, so it needs a fair amount of amplifier power. The Kin One’s measured sensitivity of about 83.4dB also falls well short of its 89dB claim.
Buy the Radiant Acoustics Clarity 4.2 when sound quality outweighs the price for you, and the Totem Kin One when the price outweighs sound quality instead.
