Built to the same exacting standard, the C12 and C15 share a strong visual aesthetic and have been designed to seamlessly and discreetly blend into any environment. Straight out of the box, your C-series monitor will operate on a single amplifier channel without the need for additional controllers or EQ.

Identical in cross section, the monitor boasts a low-profile wedge-shaped enclosure containing coaxial chassis with a 12" low frequency woofer and a 1.4" mid-high frequency tweeter with a 3" voice coil. The large mid-high horn ensures perfect mid-high frequency dispersion while its passive frequency crossover produces accurate and phase-coherent summation of low and mid-high frequencies. The low crossover frequency of the mid-high driver is particularly suited to very high quality speech reproduction.

The C12 is ideal for applications where compactness is a priority but audio quality must remain uncompromised.

The C12 also benefits from the added versatility which comes from being able to run in two-way active mode. For flexibility, the C12 can be mounted on a pole, or on surfaces using the specially developed svivel bracket SBC12 which attaches using a latching mechanism, meaning assembly does not require tools or separate, easily lost parts.

No matter whether they are used as monitors or as full range speakers, TW AUDiO's C-series enclosures combine high performance, versatility and full integration with the entire TW AUDiO range.

C12 Tonal agility.

VERA not dampened by record-breaking rains
for farewell concert

Bringing unparalleled energy to live shows with an enticing mix of ska and hip-hop, La Raíz is one of Spain’s most unique bands. For their momentous Valencia concert, a TW AUDiO sound system was deployed to help reinforce the band’s animated music, which certainly wasn’t tempered by uncharacteristically stormy weather.
