Short answer: the Edifier MR4. It ranks #72 of 108 powered bookshelf speakers by sound quality, rated 3.5/5, at $169.99; the M-Audio BX4 BT ranks #86, rated 3.3/5, and costs $218, which makes this an easy call rather than a real tradeoff.
Why pick the Edifier MR4: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. The catch: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend.
The case for the M-Audio BX4 BT: A 4.5” Kevlar woofer and 1” silk tweeter per side with Bluetooth, RCA, 1/4” TRS and a front aux input, based on the M-Audio BX4 D3. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the Edifier MR4. It is rated higher for sound quality than the M-Audio BX4 BT and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: the M-Audio BX4 BT’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.0 to 3.6, so this verdict could change once it is measured.

Edifier MR4: $169.99 per pair Amazon $169.99 eBay
Same family: the Edifier MR3 (smaller bookshelf, rated 3.8/5), the Edifier MR4.5 (larger bookshelf, ranked higher, rated 3.6/5) and the Edifier MR5 (larger bookshelf, ranked lower, rated 3.3/5).
Pros: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. Balanced TRS inputs and tone controls are practical at its price, and its response is more balanced than the measured Edifier R1280T. Measured bass extension of 79Hz (-3dB), with a measured sensitivity of 78dB.
Cons: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend. Listening-window response still has local irregularities, including lower-treble unevenness. The existing review reports rapidly increasing distortion and audible distress when pushed well above moderate desktop levels. No Bluetooth, and adding a subwoofer does not cure every output or tonal limitation.

M-Audio BX4 BT: $218.00 per pair Estimated Amazon $218.00 eBay
Same family: the M-Audio BX4 D3 (smaller bookshelf, ranked higher, rated 3.4/5), the M-Audio BX5 D3 (larger bookshelf, ranked higher, rated 3.9/5) and the M-Audio BX8 D3 (larger bookshelf, rated 4/5).
Pros: A 4.5” Kevlar woofer and 1” silk tweeter per side with Bluetooth, RCA, 1/4” TRS and a front aux input, based on the M-Audio BX4 D3.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Rated only to 69Hz, so bass is light without a subwoofer, and its 25W per side amplifiers are modest.
