Apple accessory maker Twelve South has just launched their new BassJump 2 USB subwoofer for Apple’s MacBook lineup. If you’re not familiar, same as the original BassJump, the new model aims to blend the sound output between the subwoofer and your MacBook’s built-in speakers using Twelve South’s proprietary software. In other words, the BassJump 2 sub adds the mid- and low-frequencies, your MacBook speakers act as stereo tweeters, and the software attempts to create an ideal mix between the two.

According to the company’s press release, the proprietary software used in the new model includes rewritten code that provides “greater compatibility and eight more decibels” for “dramatically enhanced sound”. The software’s UI (below), which includes a retro VU meter and other basic preset controls, has been redesigned and now allows you to save your customized settings.

When it comes to the greater compatibility, the BassJump 2 includes support for iMac and Apple Thunderbolt display speakers, as well as other non-Apple headphone-connected and USB-powered speakers.

If you’re wondering, the new software supports a frequency range of -6dB at 50Hz-20kHz, crossover frequency range of 100Hz to 300Hz, and a signal-to-nose ration of 80dB. The subwoofer itself is made of extruded aluminum, weighs 1.4 pounds and measures 2.24 inches in height, by 5-inches in weight, and a depth of 5-inches.
