IS25T is equipped with two times 5" woofers plus a 1" compression driver for the higher end.
This box provides a 60 x100° constant dispersion, and you can easily install it either vertically or horizontally using the same accessories of VIO X205.
Needless to say the keyword here is: ease of installation and unobtrusiveness. Thats why each single system in IS series comes with a smooth design with few invisible pin points, Phoenix or Speakon connectors, black or white version.
