Behringer B2030P vs Dynaudio Special Forty

Last updated: October 1, 2026

Short answer: the Behringer B2030P on value and directivity, the Dynaudio Special Forty for smoother tone. The B2030P’s CEA2034 spinorama shows strong horizontal directivity control and a wide beamwidth, though a resonance around 800Hz shows in the on-axis response and waterfall. At $220 versus $3,600 it is far cheaper, while the Special Forty’s smooth, “buttery” character is undercut by a glaring, sometimes sibilant quality around 3-4kHz.

Buy the Dynaudio Special Forty, since the Behringer B2030P is discontinued and only worth hunting down used.

Pros: CEA2034 spinorama shows strong horizontal directivity control, keeping the response nearly constant off-axis through most of the audible spectrum, with a wide beamwidth that eases seating position and toe-in requirements. Distortion measurements hold up well against the pricier Revel M106 at both 86dB and 106dB SPL. With EQ to tame a resonance around 800Hz and a bit of a bass fill, the reviewer called it a “winner” that could play loud without bottoming out. Measured bass extension of 98.1Hz (-3dB), with a measured sensitivity of 84.5dB.

Cons: A resonance around 800Hz shows up clearly in the on-axis response and the waterfall/CSD plot, and the flat, near-horizontal predicted in-room response makes it sound bright without an equalization target curve. Vertical directivity is only typical, not exceptional. Long discontinued: the reviewer noted you’ll have to hunt for a used pair.

Pros: Smooth, “buttery” overall tonal character consistent with Dynaudio’s house sound. Surprisingly precise, focused imaging despite wide horizontal radiation (about ±70°): atypical, since wide-radiating speakers usually sacrifice some image precision in reflective rooms. Strong output capability: reached 100-101dB average at 3.5 meters with no audible distortion or woofer distress, and compression testing at 102dB shows the cabinet holding up mechanically well at extreme output. Bass reaches a genuine 50Hz (potentially 40Hz) in most rooms from a rear-ported design. Distortion stays below 1% at 86dB and doesn’t cross 3% THD until about 50Hz even at 96dB. Extra weight and impact on snares and percussion around 700-800Hz that the reviewer found appealing on many tracks. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 83.5dB.

Cons: A glaring, sometimes sibilant quality around 3-4kHz was the most noticeable issue in listening, the one thing the reviewer would want notched out with EQ. Multiple enclosure resonances appear between 500Hz-1kHz across on-axis, listening window, early-reflections, and sound-power measurements, corroborated by independent third-party CSD data showing similar 500-800Hz cabinet resonances. A dip around 1.2kHz traces to a cone-edge-to-surround compliance mismatch in the driver itself (confirmed by testing the bare driver’s impedance): a known artifact common to many similarly-sized drivers across several manufacturers, contributing to elevated second-order distortion in that region. A somewhat laid-back, recessed 1-2kHz character (sometimes described as a “BBC dip”) gives an overall subdued quality that isn’t overtly problematic but shapes the tonal balance. Impedance drops below 3 ohms in the 100-200Hz region, requiring a genuinely 4-ohm-stable amplifier rather than an AVR. Rear port means it can’t be placed directly against a wall.
