The new 9S (one woofer, $1,099) and 18S subwoofers (two opposing woofers $1,949) from Dynaudio Pro feature a frequency range from 16 to 175 Hz. Powered by a high-end 300-watt Class D amplifier, the 9S long-throw driver delivers low-end extension and SPL performance, while the 18S is powered by a 500-watt amplifier and features a powerful DSP engine and built-in presets for Dynaudio Pro studio monitors. Both units come with double front baffles, adjustable lowpass filters from 50 to 150 Hz and SAT output with switchable highpass filter, all housed in sealed cabinets. Each has a signal-sensing auto-power circuit that saves energy when not in use, and for larger rooms, it is possible to daisy-chain more 9S or 18S subs, having the first unit control the overall volume.
