#18 HEDD Type 05 A-CORE: $714 per pair B&H Photo Video eBay
Pros: ASR’s Klippel data shows useful bass reach for this size, with -3dB around 44Hz. Preference scores of 4.47 standalone and 6.35 with an ideal subwoofer support it as a balanced all-round option. The AMT tweeter and analog signal path appeal to users who want a studio monitor without digital conversion or firmware dependence. Measured bass extension of 43.9Hz (-3dB).
Cons: The 2.7dB midrange span and listening-window narrow-band deviation of 0.404 trail the most linear monitors here. The response rises modestly toward the treble. The analog-only design does not provide built-in room correction or digital inputs, and published amplification power should not be read as a measured clean-output rating.
How it compares: Just above it: Sigberg Audio SBS Gen 2 - $17344 more, 150W more output power. Just below it: Kali Audio SM-5 - $2301 more, 50W less output power.
