A portable loudspeaker enclosure is made of a collapsible shell of a fabric material, e.g., canvas, having top, bottom, left, right, and back walls. These walls each are each formed of a sandwich of fabric layers and an acoustic insulation layer, such as foamed plastic or glass fiber, the insulation layer being disposed to the inside of the shell. The fabric at each wall forms a pouch co-extensive with the wall. A rigid speaker frame serves as a front wall for the enclosure and is fitted into the front of the enclosure. The frame extends within the shell towards the back wall to a point behind the loudspeaker, i.e., about one-third of the front-to-back dimension. For each wall there is a rigid batt or insert that is dimensioned to fit removably into the pouch. The batts create a rigid cavity behind the loudspeaker. The portable enclosure can have a front cover that removably covers the front wall of the enclosure, i.e., for storage and transit. The cover includes space for carrying the batts when they are removed from their pouches.

[ I claim:] [1.] A portable loudspeaker enclosure comprisinga collapsible shell having a plurality of walls; said walls each being formed of a sandwich of fabric layers and an acoustic insulation layer, with the insulation layer being disposed to the inside of the shell, and the fabric layers defining a pouch that is substantially co-extensive with the associated wall;a rigid speaker frame forming a front wall of said enclosure and fitted into said enclosure, the frame having one or more openings into which a loudspeaker is mounted, said frame extending within said shell rearwardly to a point behind said loudspeaker;a plurality of rigid batts dimensioned to fit removably into the pouches of said walls, respectively, for rigidifying said shell to create a rigid cavity behind said loudspeaker.
