Short answer: the Definitive Technology ProMonitor 1000 for bass control, the Q Acoustics 5020 for a cleaner top end, though neither ranks well in its class. Erin found the 5020 too crisp, forward and treble-heavy, with the top end roughly 3-5dB elevated while the 1-3kHz region is recessed. The ProMonitor 1000’s bass distortion is well controlled, but its spinorama shows severely reduced bass energy between 40-120Hz and a severe resonance near 14kHz. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Philharmonic Ceramic Mini ranks #2 at $900.
Buy the Q Acoustics 5020. It is rated higher for sound quality, and saving $701 with the Definitive Technology ProMonitor 1000 does not make up for the sound-quality gap.

The Two Speakers In Full
Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Pros: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 87.1dB.
Cons: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.

Definitive Technology ProMonitor 1000: $498 per pair Amazon eBay
Pros: Bass distortion is well controlled per the measurements, and the slow bass rolloff means it can be pushed fairly hard for its size. Ships with a footer that keeps the small cabinet planted despite its light weight. Measured bass extension of 95Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows severely reduced bass energy between 40-120Hz, a directivity mismatch between the tweeter and woofer, and a severe resonance/interference issue around 14kHz. Distortion at 96dB SPL was so bad the reviewer limited testing to 86dB. Direct comparison to a $118/pair Pioneer SP-BS22-LR left the reviewer calling the $249/pair ProMonitor 1000 “a bad experiment that should be forgotten” and concluding “there is nothing Pro about it.”
