In either embodiment a frame may include a back chamber and a front chamber. In the media chair, a seat support may be coupled to a support adjacent to the front chamber, the seat support may support the weight of a user. The front chamber may be at least partially defined side walls. Walls around the front chamber may be substantially continuous in construction and extend beyond the speaker so as to be able to temporarily maintain an internal sound energy greater than the sound energy outside of the front chamber. The speaker may generate the sound energy. ## Claims ### Claim 1 A sound system of the type including a speaker, the sound system comprising: a box frame comprising: a speaker support wall with the speaker mounted to the speaker support wall; a back wall adjacent to the speaker support wall, thereby defining a back chamber between the back wall and the speaker support wall; and a pair of side walls joining the back wall and the speaker support wall, the pair of side walls extending beyond the speaker support wall and opposite to the back wall, thereby defining a front chamber. ### Claim 2 (depends on 1) The sound system according to claim 1, wherein the speaker is a low frequency producing speaker. ### Claim 3 (depends on 2) The sound system according to claim 2, wherein the low frequency producing speaker is a speaker which produces a sound energy below 200 Hz. ### Claim 4 (depends on 1) The sound system according to claim 1, wherein an area defined as the back chamber is approximately twice the volume of the area defined as the front chamber. ### Claim 5 (depends on 1) The sound system according to claim 1, wherein the front chamber includes an open side that is opposite to the back wall. ### Claim 6 (depends on 1) The sound system according to claim 1, further comprising a vent port in the speaker support wall, thereby creating a passage between the front chamber and the back chamber. ### Claim 7 (depends on 6) The sound system according to claim 6, wherein the vent port is bordered by a port duct. ### Claim 8 (depends on 7) The sound system according to claim 7, wherein the port duct includes an intake port positioned in alignment with a center portion of the speaker. ### Claim 9 (depends on 7) The sound system according to claim 7, wherein the port duct is in the shape of a truncated “U”. ### Claim 10 (depends on 7) The sound system according to claim 7, wherein the port duct is positioned from the intake port around to the side of the speaker support and upward proximate to a side of the speaker, thereby allowing a portion of sound energy produced by the speaker to cycle back to the back side of the speaker. ### Claim 11 A sound system media chair comprising: a frame including a seat bottom and a seat back, the seat bottom and seat back including a continuous open end and a closed end substantially opposite to the continuous open end, the continuous open end supporting a seat support adapted to support the weight of a user; a front chamber defined by the closed end and the continuous open end, the front chamber constructed so as to be able to temporarily maintain an internal gas pressure greater than the gas pressure outside of the front chamber; and a speaker including a cone and a body, the body mounted to the frame and positioned with the cone in the front chamber. ### Claim 12 (depends on 11) The sound system media chair according to claim 11, wherein the speaker is a low frequency producing speaker. ### Claim 13 (depends on 12) The sound system media chair according to claim 12, wherein the low frequency producing speaker is a speaker which produces sound energy below 200 Hz. ### Claim 14 (depends on 11) The sound system media chair according to claim 11, wherein the seat support includes a seat cushion bottom, which supports the hips and supper legs of the user. ### Claim 15 (depends on 11) The sound system media chair according to claim 11, wherein the seat support includes a seat back cushion which supports the torso of the user. ### Claim 16 (depends on 11) The sound system media chair according to claim 11, wherein the front chamber includes side surfaces continuous with the closed end and extending to an edge of the continuous open end of the frame. ### Claim 17 (depends on 11) The sound system media chair according to claim 11, further comprising a back chamber housing a body of the speaker and a vent port positioned adjacent to the speaker, whereby the vent port provides fluid communication between the front chamber and the back chamber. ### Claim 18 (depends on 17) The sound system media chair according to claim 17, further comprising a vent extension within the back chamber, the vent extension including a wall continuous with at least one edge of the vent port, the wall extending beyond a diameter of the speaker. ### Claim 19 A sound system media chair comprising: a chair frame including a seat bottom and a seat back, the seat bottom and seat back including a substantially open end and a closed end substantially opposite to the substantially open end; a seat support, able to support the weight of the user, coupled to the substantially open end of the chair frame such that the substantially open end is covered by the seat support; a front chamber defined by the closed end and the seat support, the front chamber constructed so as to be able to temporarily maintain an internal gas pressure greater than the gas pressure outside of the front chamber; and a speaker including a cone and a body, the body mounted to the frame and positioned with the cone in the front chamber. ### Claim 20 (depends on 19) The sound system media chair according to claim 19, wherein the front chamber includes side surfaces continuous with the closed end and extending to an edge of the substantially open end of the frame.
