Adam Audio D3v vs Monoprice DT-3

Last updated: September 30, 2026

Short answer: the Adam Audio D3v. It ranks #3 of 24 powered bookshelf speakers by sound quality, rated 4.5/5, at $344.99. The Monoprice DT-3 ranks #24, rated 2.3/5, at $139.99, $205 cheaper, which does not close the gap in sound quality.

Adam Audio D3v vs Monoprice DT-3

The case for the Adam Audio D3v: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. The tradeoff: 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 case for the Monoprice DT-3: An inexpensive, compact powered pair with front volume control, auxiliary input and headphone output. The tradeoff: The measured response spans 7.6dB from 300Hz to 5kHz, with large irregularities both on-axis and across the listening window.

Buy the Adam Audio D3v. It is rated higher for sound quality, and the $205 saving on the Monoprice DT-3 is not enough to make up the difference.

Adam Audio D3v ranking card

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.

Monoprice DT-3 ranking card

Pros: An inexpensive, compact powered pair with front volume control, auxiliary input and headphone output. Erin’s Klippel measurements put the -3dB bass point around 74Hz, sufficient for some upper-bass content at a desk.

Cons: The measured response spans 7.6dB from 300Hz to 5kHz, with large irregularities both on-axis and across the listening window. Preference scores are 0.10 standalone and only 3.03 with an ideal subwoofer, among the weakest results for a powered speaker. That means adding bass support does not remove its major tonal problems. It offers little reason to choose it for accurate listening over better-measuring budget alternatives.
