AUD 17,500 is significantly above market for used Dutch & Dutch 8c speakers. Based on comparable listings in your database, the median asking price sits at AUD 11,025, with the 75th percentile at AUD 16,503—meaning this listing exceeds even the upper quartile by roughly 6%. The Dutch & Dutch 8c is a capable active speaker, but used examples typically trade in the AUD 10,000–16,000 range. At AUD 17,500, you're paying near new-condition money for a used unit, which is a tough ask unless this particular pair has extremely low hours, full documentation, and all original packaging intact.
Before committing, verify the actual condition and service history. These speakers use Class D amplification and DSP processing that can develop issues if they've been run hard or stored poorly—listen for any distortion, hum, or channel imbalance during a demo. Confirm that all original cables, remote, and setup documentation are included, and ask whether the owner has had any repairs done. If the pair is genuinely pristine with minimal use, the premium might be justifiable; otherwise, push for a discount closer to AUD 15,000–16,000 or walk.
