Add deep, controlled bass to any home theater or stereo system with the ULTIMEA SUB-10 10" Powered Subwoofer. Delivering 550W peak power through a 10" high-excursion driver and Class-D amplification, the SUB-10 reaches down to 20Hz for impactful low-end that grounds movies, music, and games. An engineered composite cone and robust driver structure work together to deliver tighter, cleaner, and more controlled low frequencies, while a high-rigidity wood cabinet suppresses unwanted resonance and vibration for greater clarity and a more natural tone.Setup is flexible thanks to the included wireless subwoofer adapter. Connect compatible AVRs, soundbars, or audio systems wirelessly: run an RCA or sub-out cable from your source to the adapter, and the subwoofer can be placed anywhere in the room without a long subwoofer cable. The rear panel also offers professional wired connections, including Line/LFE input, line output to pass the signal to another subwoofer or audio device, balanced XLR in/out for HiFi preamps and professional setups, and speaker-level input for amplifiers without a subwoofer output.Fine-tune everything from the ULTIMEA App. Adjust volume, set the low-pass crossover between 30Hz and 180Hz to match your main speakers, and dial in phase with 1° precision over the app-complemented by a rear-panel 0°–180° phase switch. A 6-band custom parametric equalizer lets you adjust frequency, boost, and Q-factor for room-perfect bass, alongside EQ presets. A removable protective grille keeps the 10" driver safe from dust and accidental contact.In the box: SUB-10 subwoofer, removable protective grille, wireless subwoofer adapter, power cable with adapter plug, RCA cable, 3.5mm-to-RCA cable, adapter 3.5mm-to-RCA cables, adapter USB power cable, and user manual.
