InVincible™ is the world’s first hyper-high-end sub-bass speaker. It was 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. YG Acoustics™ addressed the issue by creating a truly extreme
solution, a no-holds-barred assault on everything deemed possible in the
sub-bass realm. inVincible – pure authority, handmade in U.S.A.

Innovations include, first and foremost, the largest BilletCore™ driver ever made
at 53 cm diameter (21”). The cone is machined from a massive 30 kg (66 lb) slab
of aircraft-grade aluminum. When finished it weighs 411 grams (14.5 oz). The
basket is also CNC-machined in-house, then precisely assembled from 238 parts
using lab-grade alignment and tolerances.

The 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

The unique layout sports dual, opposing-yet-tilted drivers. It combines the
freedom from vibration of a push-push setup, with the ease of room-integration
typically associated with front-firing subwoofers. The “flipped” arrangement, with
enclosures on both ends rather than in-between the woofers, minimizes their
spacing thus further easing room-placement.

The cabinet is precisely CNC-machined from solid aluminum billet. Like YG
Acoustics™’ flagship Sonja™ XV and Sonja™ 2 series, its construction is a “box
within a box”, to minimize vibration. A sealed alignment eliminates port-issues
and the time-delays associated therewith. FocusedElimination™ is used to
minimize loss.

The built-in DSP crossover offers extensive options for matching with most
high-end speakers. Furthermore, when mating inVincible™ with a YG
Acoustics™ speaker, the guesswork is entirely eliminated. InVincible™ is
pre-programmed for precise matching with any current YG Acoustics™ speaker
and many legacy models, using a foolproof process inspired by the famous
DualCoherent™ technology.

At YG Acoustics™, we pride ourselves in protecting our discerning customers’
investments for many years to come. We do so by ensuring that one almost
never needs to replace any of the YG Acoustics™ offerings listed below. Instead,
existing products can mostly be upgraded to the latest technology, and/or
expansion modules can be added.

In most cases, upgrades and expansions can be done in the field (i.e. in the
customer’s home) without the need to ship the speakers anywhere, in a matter of

InVincible™ is available in three fully modular configurations, which can be
expanded 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.
inVincible™ is fully compatible with both two-channel (stereo), and multi-channel
audio and home theater systems.
