An improved manually mountable ceiling speaker enclosure, the improvement comprising

• a. a rim assembly comprising:
• i. an annular rim operable as a jaw of a clamp;
• ii. an annular wall extending inside said annular rim;
• and
• iii. an inner annular support panel extending inside said annular wall;
• and
• b. a plurality of flip dog assemblies, each comprising
• i. three openings aligned to three openings in said inner annular support panel;
• ii. a flip dog having a plurality of arcuate upward pointing teeth extending from a barrel of said flip dog;
• iii. an arcuate chamber operable to slidingly receive said barrel and having an opening for receiving an end of a biased slidable ratchet block;
• and
• iv. an integral actuator comprising:
• 1. a rod extending slidably through a first opening of said three openings and slidably through said barrel and configured to both pull said flip dog downward in said chamber and to travel upward without restriction from said barrel;
• 2. a T-handle extending across a bottom end of said rod;
• 3. a latch extending upward from said T-handle and configured to fit slidingly into a second opening of said three openings.
