The first portion and the second portion are shaped such that sound emitted from the first speaker driver and the second speaker driver is reflected and focused toward the listener. ## Claims ### Claim 1 A system for enhancing sound provided by at least a pair of speaker drivers relative to a listener, comprising: a structure, defining: a first portion of an oblong enclosure that forms an approximated double ellipse profile, comprising a material having a sound reflective surface, and positioned between a first area proximate a first speaker driver and a second area proximate the listener, wherein the first portion of the oblong enclosure forms a first part of the approximated double ellipse profile; and a second portion of the oblong enclosure that forms the approximated double ellipse profile, comprising a material having a sound reflective surface, and positioned between a third area proximate a second speaker driver and a fourth area proximate the listener, wherein the second portion of the oblong enclosure forms a second part of the approximated double ellipse profile, wherein the first portion and the second portion together envelop the listener with the approximated double ellipse profile and are shaped such that sound emitted from the first speaker driver and the second speaker driver is reflected and focused toward the listener. ### Claim 2 (depends on 1) The system of claim 1, wherein the oblong enclosure is elongated and has a width that is longer than a length thereof. ### Claim 3 (depends on 2) The system of claim 2, further comprising a template having a first side and an opposing second side, the opposing second side configured to be disposed along a ground. ### Claim 4 (depends on 3) The system of claim 3, further comprising a speaker positioning system including two or more points that correspond to one or more speaker locations. ### Claim 5 (depends on 3) The system of claim 3, further comprising a positioning system including one or more arcs that define one or more positions for the first portion and the second portion. ### Claim 6 (depends on 1) The system of claim 1, wherein the first portion and the second portion are substantially symmetrical in shape and position. ### Claim 7 (depends on 1) The system of claim 1, wherein the first portion is curved to reflect sound emitted at one or more angles relative to a sound axis of the first speaker driver; wherein the curvature of the first portion directs sound toward the listener via the reflection; wherein the second portion is curved to reflect sound emitted at one or more angles relative to a sound axis of the second speaker driver; wherein the curvature of the second portion directs sound toward the listener via the reflection. ### Claim 8 (depends on 1) The system of claim 1, wherein the first portion is curved outwardly, away from a center of the oblong enclosure in at least one section to reflect sound emitted at one or more angles relative to a sound axis of the first speaker driver; wherein the curvature of the first portion directs sound toward the listener via the reflection; wherein the second portion is curved outwardly, away from the center of the oblong enclosure in at least one section to reflect sound emitted at one or more angles relative to a sound axis of the second speaker driver; wherein the curvature of the second portion directs sound toward the listener via the reflection. ### Claim 9 (depends on 1) The system of claim 1, wherein the structure comprises one panel, wherein the first portion and the second portion are integrally formed and define a single unitary body. ### Claim 10 (depends on 1) The system of claim 1, wherein the structure comprises a first panel and a second panel not integrally formed with the first panel, wherein one or more areas of the first panel comprises the first portion and one or more areas of the second panel comprises the second portion. ### Claim 11 (depends on 1) The system of claim 1, wherein one or more areas of the first portion and one or more areas of the second portion extend behind the listener such that sound is reflected to the listener from behind the listener. ### Claim 12 (depends on 1) The system of claim 1, wherein at least one of the first speaker driver and the second speaker driver comprise a tweeter, wherein the first portion extends vertically to a height that is vertically offset from the tweeter by at least 0.2 meters, wherein the second portion extends vertically to a height that is vertically offset from the tweeter by at least 0.2 meters. ### Claim 13 (depends on 1) The system of claim 1, further comprising: a sound reflector that is smaller in size than an area of the structure and that extends horizontally from a surface of the first portion, the sound reflector positioned to reflect sound emitted by at least one of the pair of speaker drivers toward the listener that were emitted at vertically offset angles from the at least one of the pair of speaker drivers. ### Claim 14 (depends on 13) The system of claim 13, wherein the sound reflector is curved. ### Claim 15 (depends on 13) The system of claim 13, wherein the structure and the sound reflector are integrally formed and define a single unitary body. ### Claim 16 (depends on 1) The system of claim 1, further comprising: a channel configured to hold the structure in at least one of a desired vertical position and a desired horizontal position. ### Claim 17 A kit, comprising: a structure, the structure defining: a first portion of an oblong enclosure that forms an approximated double ellipse profile, comprising a material having a sound reflective surface, and configured to extend between a first area proximate a first speaker driver and a second area proximate a listener, wherein the first portion of the oblong enclosure forms a first part of the approximated double ellipse profile; and a second portion of the oblong enclosure that forms the approximated double ellipse profile, comprising a material having a sound reflective surface, and configured to extend between a third area proximate a second speaker driver and a fourth area proximate the listener, wherein the second portion of the oblong enclosure forms a second part of the approximated double ellipse profile, wherein the first portion and the second portion are configured to be shaped such that they together envelop the listener with the approximated double ellipse profile and sound emitted from the first speaker driver and the second speaker driver is reflected and focused toward the listener. ### Claim 18 (depends on 17) The kit of claim 17, further comprising a template having a first side and an opposing second side, the opposing second side configured to be disposed along a ground. ### Claim 19 An audio system, comprising: a first speaker driver and a second speaker driver; a structure, the structure defining: a first portion of an oblong enclosure that forms an approximated double ellipse profile, comprising a material having a sound reflective surface, and positioned between a first area proximate the first speaker driver and a second area proximate a listener, wherein the first portion of the oblong enclosure forms a first part of the approximated double ellipse profile; and a second portion of the oblong enclosure that forms the approximated double ellipse profile, comprising a material having a sound reflective surface, and positioned between a third area proximate the second speaker driver and a fourth area proximate the listener, wherein the second portion of the oblong enclosure forms a second part of the approximated double ellipse profile, wherein the first portion and the second portion are shaped such that they together envelop the listener with the approximated double ellipse profile and sound emitted from the first speaker driver and the second speaker driver is reflected and focused toward the listener. ### Claim 20 (depends on 19) The audio system of claim 19, wherein the first speaker driver and the second speaker driver are at least one of removably, adjustably, and fixedly integrated as part of the panel structure.
