The Two Speakers In Full
Kanto ORA4: $349.99 per pair Amazon eBay
Pros: 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. Inputs cover RCA, USB-C audio and Bluetooth 5.0, and a subwoofer output engages an automatic 80Hz crossover. Rear ports and a front volume knob that also switches inputs.
Cons: Kanto rates the response only down to 60Hz, so a subwoofer helps for deep bass, and there is no optical input. Erin’s Audio Corner has measured it, but the numbers the other speakers here are ranked on aren’t available yet, so it can’t be placed against them.

Adam Audio D3v: $344.99 per pair Amazon eBay
Pros: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile LBM. Predicted preference scores of 5.37 standalone and 7.59 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.
