OS Acoustics DBS8 OS Acoustics have followed up their impressive DB7 with an even more capable twin‑woofer design. We put the new DBS8 to the test. Back in April 2018 I reviewed OS Acoustics’ debut monitor, the DB7, and very much admired it. The newly developed and launched DBS8 not only extends the OS Acoustics monitoring range upwards in terms of price and performance aspirations, but also offers a somewhat different electro‑acoustic design philosophy. Where the DB7 is a conventional reflex‑loaded two‑way system, the DBS8 is a closed‑box design, sporting twin bass/mid drivers in a D’Appolito configuration. These changes ought to endow the DBS8 with a significantly different performance character, both objectively and subjectively, compared to the DB7.
