Same family: the Kanto ORA (smaller bookshelf, ranked lower, rated 3.7/5).
Pros: Compact desktop speakers with good sound for the size, deeper bass than most desk speakers, and USB-C and Bluetooth inputs. Compact powered desktop speakers with 4-inch aluminum-cone woofers and 3/4-inch silk-dome tweeters in waveguides, bi-amplified with 70W RMS in total. Erin’s Audio Corner’s Klippel measurements show a well-behaved design for the size: the listening window stays within about a 4.5dB span from 300Hz to 5kHz and tracks the on-axis response closely, and the predicted in-room response is smooth. Bass goes deeper than most desktop speakers, to about 54Hz at -3dB and 43Hz at -10dB, and a subwoofer output with an automatic 80Hz crossover makes adding one easy. Inputs cover RCA, USB-C audio and Bluetooth 5.0. Measured bass extension of 54Hz (-3dB).
Cons: Its score here is our estimate: spinorama.org hasn’t published numeric data for it yet, so we traced Erin’s Audio Corner’s published charts, which put its preference score with an ideal subwoofer at roughly 6.9, level with the better small powered speakers but short of the best. Treble sits slightly above the midrange, and there is no optical input. Kanto’s own rating stops at 60Hz, so a subwoofer still helps for deep bass at higher volumes.
