Magico

QSub 15

Introduced 2013$22,000 MSRP

The QSub 15 was Magico's first purpose-built subwoofer, designed for both high-end two-channel music systems and multichannel home theater, pairing dual 15-inch woofers in a rigid, roughly 2-inch-thick aluminum-baffled sealed enclosure with an onboard digitally controlled active crossover (source: [Audioholics](https://www.audioholics.com/subwoofer-reviews/magico-qsub-18-and-qsub-15-subwoofer-preview), [The Absolute Sound](https://www.theabsolutesound.com/articles/magico-q-sub-15-and-raidho-d-51/)). Magico rated the QSub 15 capable of 136 dB SPL at 20 Hz with under 1% total harmonic distortion, and the crossover can be bypassed for use with an external home-theater processor (source: [aulet.vn](https://aulet.vn/magico-q-sub-15), [Audioholics](https://www.audioholics.com/subwoofer-reviews/magico-qsub-18-and-qsub-15-subwoofer-preview)).
