Abstract
A ported speaker assembly includes an outer enclosure having a front opening. An inner frame of the speaker assembly is positioned at least partially within the outer enclosure and has an outer perimeter edge proximate the front opening of the outer enclosure. A resonator chamber is defined between an interior of the outer enclosure and an exterior of the inner frame. At least one speaker driver is mounted to the inner frame and configured to emit sound from a front end of the ported speaker assembly. A perimeter port is formed between the outer perimeter portion of the inner frame and the front opening of the outer enclosure. The perimeter port extends uninterrupted to encircle the outer perimeter portion. A plurality of fastener joints secure the inner frame to the outer enclosure, and at least some are distributed around multiple sides of the inner frame and positioned closer to the front opening of the outer enclosure than a rear end of the inner frame.
