Short answer: the PreSonus Eris Studio 5. It ranks #63 of 100 powered bookshelf speakers by sound quality, rated 3.6/5, at $299.98. The PreSonus Eris Studio 4 ranks #74, rated 3.4/5, at $259.98, $40 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the PreSonus Eris Studio 4: The smallest Eris Studio monitor, with a 4.5” woven composite woofer and 1” silk-dome tweeter in an elliptical waveguide that spreads sound wide horizontally while limiting reflections off the desk below. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the larger Eris Studio 5 and the measured Eris Studio 8.
The case for the PreSonus Eris Studio 5: A 5.25” woven composite woofer and 1” silk dome tweeter on a 120° x 60° EBM waveguide for a wide sweet spot. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the PreSonus Eris Studio 5. It is rated higher for sound quality, and the $40 you would save on the PreSonus Eris Studio 4 does not close the gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: PreSonus Eris Studio 4 3.0 to 3.7; PreSonus Eris Studio 5 3.4 to 3.8). Treat this verdict as provisional.

PreSonus Eris Studio 4: $259.98 per pair Estimated B&H Photo Video eBay
Same family: the PreSonus Eris Studio 5 (larger bookshelf, ranked higher, estimated 3.6/5) and the Presonus Eris Studio 8 (larger bookshelf, rated 3.9/5).
Pros: The smallest Eris Studio monitor, with a 4.5” woven composite woofer and 1” silk-dome tweeter in an elliptical waveguide that spreads sound wide horizontally while limiting reflections off the desk below. It is bi-amplified with 50W and accepts balanced TRS and RCA. Acoustic Space settings for wall or corner placement plus high-pass, midrange and treble controls help it fit a small desk.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the larger Eris Studio 5 and the measured Eris Studio 8. Bass stops around 55Hz and output peaks near 100dB, so it suits near-field desk listening more than filling a room.

PreSonus Eris Studio 5: $299.98 per pair Estimated Amazon eBay
Older model: the Presonus Eris E5 XT (ranked lower, rated 3.5/5).
Same family: the PreSonus Eris Studio 4 (smaller bookshelf, ranked lower, estimated 3.4/5) and the Presonus Eris Studio 8 (larger bookshelf, rated 3.9/5).
Pros: A 5.25” woven composite woofer and 1” silk dome tweeter on a 120° x 60° EBM waveguide for a wide sweet spot. 80W Class AB bi-amplification rated to 102dB peak, a front-firing port, and balanced XLR and TRS plus unbalanced RCA inputs. PreSonus rates response at 48Hz to 20kHz.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Sold individually, so a stereo pair costs twice the listed price.
