The 9S subwoofer brings studio-grade precision to your monitoring setup, perfectly engineered to work alongside LYD and classic BM range monitors from Dynaudio Pro. This compact powerhouse features studio-quality components and construction, including a double front baffle design and brand-new 9-inch long-throw driver that makes it ideal for both mixing and mastering applications. Dynaudio has prioritised creating a compact form factor without compromising sonic accuracy. The 9S matches the physical dimensions of the BM 9S II it replaces, yet its performance rivals that of the much larger BM 14S II. This impressive achievement means you get exceptional capability in a space-efficient package. The subwoofer enhances any studio monitor configuration, from stereo to surround setups. Its massive yet controlled low-end response relieves your main monitors from handling the demanding lower frequencies, allowing them to focus on the frequency range above 50-150Hz depending on your crossover filter settings. The long-throw driver provides the necessary excursion to reproduce super low-end frequencies down to 22Hz with remarkable detail, all powered by a robust 300W Class D amplifier module that significantly outperforms its predecessor.
