Short answer: the BIC America DV62si if you want to play loud, the Harbeth Monitor 30 if you value an easy load, though neither ranks well in its class. The BIC’s 6.5 inch woofer gives it real dynamic headroom, and the reviewer praised its loud, strong-bass ability, but its CEA2034 spinorama shows uneven, elevated high frequencies and the worst horizontal directivity plot we have seen. The Harbeth is easier to drive at 85dB, 6-ohm nominal, yet dips on-axis from around 3kHz. Both are rated below 3.0/5 among the 134 bookshelf speakers, and the AsciLab C6B, ranked #6 at $1,145, is a better place to start if sound quality matters.
Buy the BIC America DV62si, since the Harbeth Monitor 30 is discontinued and only worth hunting down used.

The Two Speakers In Full
BIC America DV62si: $164.90 per pair Amazon eBay
Pros: A larger-than-typical 6.5” woofer for the price gives it real dynamic headroom: the reviewer called the ability to play loud with strong bass a genuine strength, uncommon among budget speakers with smaller drivers. Impedance is comfortably high for the amplifier to drive. Extremely popular with buyers (429 Amazon ratings averaging 4.5 stars at the time of review). Measured bass extension of 80Hz (-3dB), with a measured sensitivity of 85dB.
Cons: CEA2034 spinorama shows uneven, elevated high-frequency response and what the reviewer called “the worst horizontal directivity plot we have seen”: direct and reflected sound diverge badly. Distortion is elevated across the board at 96dB SPL. The reviewer’s take: the elevated highs create an initial “high-resolution” impression that wins over casual listeners and drives the strong online ratings, but extended listening reveals harshness and grittiness; “I can’t recommend the BIC DV62si even though I understand why the popular vote is so strongly in its favor.”

Harbeth Monitor 30: $3,200 per pair Discontinued eBay
Newer model: the Harbeth M30.3 XD2. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: Sensitivity of 85dB and a 6-ohm nominal impedance (150W handling) make it reasonably easy to drive despite the impedance dropping to about 4.8 ohms at points. Wide bandwidth 2-way design with a 7.9” bass/midrange driver and 1” soft dome tweeter. Measured bass extension of 64.5Hz (-3dB), with a measured sensitivity of 87dB.
Cons: CEA2034 spinorama shows a significant on-axis dip starting around 3kHz at the crossover point, which the reviewer called “the classic engineering work of calling a defect a feature” rather than the intentional character it’s often described as. Predicted in-room response is uneven with an exaggerated tilt toward high frequencies. Step response shows the tweeter and woofer out of phase with each other. At $3200 per pair, the reviewer concluded the price doesn’t match the measured performance. Discontinued.
