Apt-TB1281 MK2 (Horn loaded medium throw)

The Apt-TB1281 horn loaded medium throw cabinet with a flat non-aggressive sound reproduction and high output has a wide range of applications. Hugely popular as a touring product and for live DJ sets, this cabinet is suitable for smaller venues whilst also being scalable (in pairs) for use in larger settings.

This high output cabinet packs a punch for its size and produces flat, non-aggressive sound reproduction allowing for minimal correction time straight out of the box.

Apt-TB121 Mk2 is cross-compatible across the audio range and works beautifully with our amplifier and 2 x SC18.1 Subwoofers to create an all-round system. If you prefer to add this cabinet to your existing system, industry standard Neutrik connections will make it a breeze.

Manufactured using high grade birch ply-wood and quality components, the Apt-TB1281 is built to last.
