Add deep, controlled bass to any home theater or stereo system with the ULTIMEA SUB-12 12" Powered Subwoofer. Delivering 900W peak power through an engineered 12" high-excursion driver and Class-D amplification, the SUB-12 reaches down to 18Hz for impactful low-end that grounds movies, music, and games. The engineered 12" driver delivers deeper, tighter, more controlled bass, while the wood cabinet suppresses unwanted resonance and vibration for greater clarity.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 (CH1/CH2) 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 such as Movie. A removable protective grille keeps the 12" driver safe from dust and accidental contact.In the box: SUB-12 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.
