The Resolution 1.5TT is a two-way enclosure specifically designed for mid sized venues with low ceiling heights.  Combining twin 12” drivers as used in the Resolution 1 with the 90 degree dispersion 5“ from the Resolution 1.5, it can be neatly installed tight against a ceiling providing good coverage due to the built-in downward angle of the devices.  Its already strong bass response can be further extended with a wide range of Funktion One bass enclosures, particularly the BR and F series.

Product Rating

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
