Short answer: the JBL 305P MKII. It ranks #13 of 68 powered bookshelf speakers by sound quality, rated 4.3/5, at $289. The Presonus Eris E5 XT ranks #47, rated 3.5/5, at $239.98, $49.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the JBL 305P MKII does well: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. The tradeoff: The 3.3dB midrange span and rising response show it is not perfectly neutral.
The case for the Presonus Eris E5 XT: ASR’s measurements show reasonably consistent directivity through the crossover, so EQ changes are more likely to benefit both direct and reflected sound. Watch for: The response has bass and treble emphasis with a recessed crossover region; smooth directivity carries that imbalance into room reflections rather than fixing it.
One note: the Presonus Eris E5 XT is no longer in production and isn’t widely stocked new anymore.
Buy the JBL 305P MKII. It is rated higher for sound quality, and the $49.02 saving on the Presonus Eris E5 XT is not enough to make up the difference.

JBL 305P MKII: $289.00 per pair Amazon eBay
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.

Presonus Eris E5 XT: $239.98 per pair Discontinued eBay
Newer model: the PreSonus Eris Studio 5. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: ASR’s measurements show reasonably consistent directivity through the crossover, so EQ changes are more likely to benefit both direct and reflected sound. Bass reaches -3dB around 56Hz. A standalone preference score of 3.58 rises to 6.00 with an ideal subwoofer, indicating useful bass reach but only moderate native tonal performance. Measured bass extension of 56.4Hz (-3dB).
Cons: The response has bass and treble emphasis with a recessed crossover region; smooth directivity carries that imbalance into room reflections rather than fixing it. Existing distortion testing shows problems across a broad range when pushed to 96dB. Tone correction and moderate levels help, but it is not a reference-flat monitor out of the box. Discontinued.
