The S10.4 delivers a 10' glass-aramid woofer and Class D amplification that combine for a punchy, tight bass response down to 28Hz and a claimed max SPL of 117 dB. That combination makes it a practical choice for mixing electronic, rock and heavy music where bass clarity and impact below 60Hz matter most, while preserving full-range accuracy for monitor pairing.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10' glass-aramid woofer:\u003c\/strong\u003e Provides tight, defined low frequencies that translate mixes with accuracy and controlled punch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass extension to 28Hz:\u003c\/strong\u003e Reaches deep sub-bass for electronic and cinematic material, letting engineers hear energy below the usual monitor range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e117 dB max SPL:\u003c\/strong\u003e Delivers plenty of level for nearfield and small-room monitoring without immediate distortion at moderate volumes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable four-position crossover:\u003c\/strong\u003e Makes it simple to match the subwoofer crossover to a variety of studio monitors for a coherent low end.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFootswitch control (footswitch not included):\u003c\/strong\u003e Lets users engage or bypass the sub and crossover quickly while keeping the sub powered for convenience during sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurved front-firing port and lightweight Class D amp:\u003c\/strong\u003e Offer flexible placement in rooms and responsive transient control without excessive weight.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe S10.4 is best for mixing engineers and producers working in small to medium project studios who need an authoritative sub that integrates with existing nearfield monitors.
