Critic Reviews

Dynaudio 9S & 18S Subwoofers Review - For A Detailed Reveal

musictech.com

Dynaudio's 9S and 18S subwoofers deliver impressive low-end extension and clarity, but buyers should weigh their specific needs against the hefty price tags of £795 and £1,400. While both models offer robust build quality and ease of integration with existing monitors, the 18S may be overkill for smaller studios. The 9S provides a subtle enhancement to bass control, making it a solid choice for precise mixing. However, those not working in larger spaces might find limited benefit. Ultimately, these subs shine in the right settings, but their cost and potential redundancy for some users could dampen enthusiasm.
