TW-Audio C15 Coaxial reference


Built to the same exacting standard, the C15 and C12 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 15″ 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.

Especially when additional bass extension is required, the C15 will offer a robust low end response, refined with the enclosure’s generously dimensioned bass reflex channels for a tightly defined, punchy response that you will feel as well as hear.

The C15 also benefits from the added versatility which comes from being able to run in two-way active mode. For flexibility, the C15 can be mounted on a pole, or on surfaces using the specially developed svivel bracket SBC15 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.
