Available in AudioTools on the App Store

View plots, see 3D response patterns, and get all of the information needed for installation and design work.


Save favorites, sort by type, manufacturer, half sphere/full sphere, and even limit by weight.

All loudspeaker CLF files are downloaded from our servers, and then stored on your iOS device.

Plots include sensitivity, impedance, 6dB response, polar response, and 3D graphical and color images.

On iPad, see all graphs at once. On iPhone / iPod touch, one graph is shown at a time.
