About this item

Product details

ULTIMEA SUB12 12" Powered Subwoofer with Wireless Adapter, App Bass Control
  • Wireless Adapter for Up to Two Subwoofers: SUB12 includes a wireless subwoofer adapter for flexible low-frequency signal transmission with under 20 ms low latency. The adapter can pair with up to two SUB12 units, allowing single-sub or dual-sub placement without running long subwoofer signal cables across the room. This helps simplify installation for home theater, HiFi, soundbar, and bookshelf speaker systems. Each subwoofer still requires AC power.
  • 900W Peak Power and 18Hz Low Frequency: The 12-inch high-excursion driver with Class-D power delivers up to 900W peak output and extends low-frequency response down to 18Hz for dedicated bass in home theater, HiFi, music, and gaming setups.
  • App Bass Control with 1° Phase Adjustment: Use the ULTIMEA App to adjust volume, low-pass crossover, 6-band parametric EQ, and phase from 0° to 180° in precise 1° steps for detailed bass tuning. The rear-panel phase switch offers 0° or 180° settings for quick manual adjustment, helping the subwoofer blend seamlessly with your speakers.
  • 30-180Hz Low-Pass Control: SUB12 lets you adjust the low-pass crossover from 30Hz to 180Hz, allowing the subwoofer to blend with different main speakers and room setups. Set a lower crossover point for larger speakers, or a higher crossover point for smaller speakers that need more low-frequency support.
  • Professional Inputs and Outputs: SUB10 supports multiple connection options, including Line/LFE input, RCA input/output, XLR balanced input/output, and speaker-level input. It works with compatible AV receivers, amplifiers, soundbars, HiFi systems, bookshelf speaker setups, and professional audio devices.
  • Engineered Cabinet and Complete Accessories: The engineered wood cabinet and removable protective grille support stable low-frequency playback while protecting the 12" driver. The package includes the subwoofer, protective grille, power cable, RCA cable, 3.5mm to RCA cable, wireless adapter, dongle cables, USB power cable, and user manual.

Best Projector Hands Down

We have gone through several projectors over the years and a common theme is difficulty in formatting the image to the correct size and format. Another major issue is the need to always connect to another source to access digital information such as a phone or laptop. This projector eliminates both of these issues with the best autoformatting we have ever used and access to dozens of different video apps like Netflix, Prime and Roku directly on the device without the need for additional hardware.

Works great!

Wonderful value for the price. I bought it as a Christmas gift and it's been used while relaxing in bed. Clarity could be a bit better but for the price you can't really beat it.
