InVincible is the world’s first hyper-high-end sub-bass speaker.

Created to solve a specific problem: owners of the world’s finest flagship speakers often felt that adding a subwoofer to their system caused more drawbacks than improvements. By pushing the conventional boundaries of possibility, YG Acoustics incorporated proprietary, leading-edge technology to devise a no-holds-barred assault on everything deemed possible in the sub-bass realm.

InVincible introduces the largest-ever BilletCore driver. Machined, in-house, from a massive, 30 kg (66 lb) slab of aircraft-grade aluminum, this cone measures 53 cm (21”) in diameter and weighs just 411 grams (14.5 oz.).

A dedicated, built-in amplifier boasts up to 6,000 watts of RMS power for unrestricted dynamics. In a world filled with offshore-outsourced electronics, this amplifier stands out by incorporating a real high-end, custom, U.S.-made class D module.

InVincible is available in three fully modular configurations, which can beexpanded from smaller to larger, without the need to replace existing modules:

• InVincible 21.1 – an ultra-high-end single-driver subwoofer.

• InVincible 21.1i – a down-firing configuration of the above, to protect the driver in busy high-traffic households, or to allow for placement of a center-speaker on the flat top surface.

• InVincible 21.2 – the flagship; a large, ultra-high-end dual-driver subwoofer.
