The JBL 305P MKII is the more accurate, deeper-bass choice. Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.38 against -0.06 for the Donner Dyna 3. Its bass reaches about 50Hz before falling 3dB, against 85Hz for the Donner Dyna 3. Watch for: The 3.3dB midrange span and rising response show it is not perfectly neutral.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5).
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Donner Dyna 3 eBay
Pros: A low-cost powered desktop pair with several input options and a small footprint. It can provide basic close-range background playback without an external amplifier. Measured bass extension of 85.0Hz (-3dB).
Cons: Erin’s Klippel measurements give a negative standalone preference score of -0.06 and only 3.24 with an ideal subwoofer. The response spans 8.2dB from 300Hz to 5kHz, with large listening-window irregularities. Bass reaches -3dB around 85Hz, and the existing review reports distortion and compression limits. It is not a credible neutral studio monitor despite that style of marketing.
