manufacture of professional loudspeaker products. We take great pride in engineering and building every Wharfedale Pro

FOCUS SERIES OVERVIEW

Music to the masses

With the Wharfedale Pro Focus point-source array system you now have a solution that provides not just exceptional

quality sound but also a exible cabinet and hardware conguration enabling you to meet the requirements of a wide

variety of venues. Focus’ easy adaptability makes it perfect for portable rentals, touring and stage shows.

Optimised acoustic engineering

The Focus family has 4 components to choose from - a 12” and 15” PA and a 18” and twin 18” subwoofer. Focus tops
and subs are superbly engineered to work together seamlessly and provide maximum efficiency. The two-way PA
speakers employ a High-Q 100° x 10° long-throw waveguide horn geometry to project the sound au the way to the back
of large listening areas. All this comes together to create a point-source array system!

Meets your needs

Focus hardware allows you to y in a line-array conguration, y independently and in pairs or stack PA’s on top of subs.

Focus adapts perfectly to whatever challenges your venue presents you with!

Sonic Impact

At peak output a single Focus-15 can pump out 135db SPL; maximum power handling is rated at 2800 watts peak.
Focus subs put out an equally impressive 146dB peak SPL of pounding bass with a maximum power handling capacity
of 8000 watts peak. Need more? Just double up! The Focus V-Tech side-by-side driver placement maximizes mutual
coupling and boundary-effect reinforcement to move massive amounts of air and push the beat to the soul of your
audience.
