A speaker cabinet to effectively amplify an acoustic guitar, comprising of: two chambers, two speaker drivers, a port, and a tube within the port. One speaker driver is mounted onto front of tube to radiate sound outwards, while the rear sound waves radiate through same tube into ported resonant chamber. The second chamber is sealed, is next to ported chamber, and utilizes a second speaker driver. The front sound waves of second driver radiant into ported resonant chamber, while the rear waves radiate into the sealed chamber. The two distinct sound waves now inside ported chamber mix with each other, then flow around the tube and through the port. All three sound waves mix in front of the cabinet. Other embodiments include: Sound deflectors, horn-loading the port, a passive radiator on the sealed chamber to radiate a fourth sound wave, and a guitar shape inside the ported resonant chamber.
