The subject invention is directed to a portable entertainment system that includes a housing unit and an audio system supported by the housing unit. A transport structure is coupled to the housing unit such that the housing unit is portable. The audio system includes electronic audio equipment and at least a first pair of speakers coupled to the electronic audio equipment. The housing unit contains a speaker enclosure and a support panel is disposed between and substantially parallel to the front and rear panels and the support panel divides the speaker enclosure to form a front air-filled section and a rear air-filled section. A first audio port extends through the housing unit into a front air-filled section of the speaker enclosure and a second audio port extends through the housing unit at least into a rear air-filled section of the speaker enclosure. When a first pair of speakers moves towards the rear panel in response to electrical signals from the electronic equipment, compressed air within the rear air-filled section flows out of a second audio port and when the first pair of speakers moves towards the front panel in response to electrical signals from the electronic equipment, compressed air within the front air-filled section flows out of a first audio port.

1. A portable entertainment system, comprising:a housing unit;an audio system supported by the housing unit, the audio system comprising electronic audio equipment and at least a first pair of speakers coupled to the electronic audio equipment; anda transport structure coupled to the housing unit such that the housing unit is portable,wherein the housing unit comprises:a speaker enclosure defined bya front panel;a rear panel;a top surface;a bottom surface; andopposing first and second side panels adjoining the front and rear panels;a support panel disposed between and substantially parallel to the front and rear panels, the support panel dividing the speaker enclosure to form a front air-filled section and a rear air-filled section, and configured to support the first pair of speakers thereon such that a first portion of each speaker is exposed to the front air-filled section and a second portion of each speaker is exposed to the rear air-filled section;at least a first audio port extending between the front air-filled section of the speaker enclosure and the rear panel; andat least a second and third audio port formed between the support panel and the rear panel of the housing unit;wherein, when the first pair of speakers moves towards the front panel in response to electrical signals from the electronic equipment, resulting compressed air within the front air-filled section flows out of the first audio port; andwherein, when the first pair of speakers moves towards the rear panel in response to electrical signals from the electronic equipment, resulting compressed air within the rear air-filled section flows out of the second audio port.2. The system as recited in claim 1, wherein the audio equipment is selected from a group consisting of a CD player, and MP3 player and an AM/FM tuner.3. The system as recited in claim 1, further comprising video equipment supported by the housing unit.4. The system as recited in claim 3, wherein the video equipment is selected from a group consisting of a DVD player, VCD player, television and image projector.5. The system as recited in claim 1, wherein the at least a first pair of speaker comprises a pair of woofers.6. The system as recited in claim 1, wherein the first audio port comprises at least one bass port having an elongate body extending between a first open end and a second open end, wherein the first open end is located in the rear panel and the second open end is disposed in the front air-filled section of the speaker enclosure, and wherein the second and third audio port comprises at least one aperture formed in and extending through at least one of the first and second side panels into the rear air-filled section of the speaker enclosure.7. The system as recited in claim 1, wherein the audio system comprises a second pair of speakers supported by the housing unit, and wherein the second pair of speakers are middle and high range speakers.8. The system as recited in claim 1, wherein the audio system comprises a detachable pair of speakers detachably connected to the rear panel.9. The system as recited in claim 1, wherein the transport structure comprises an axle and a pair of wheels.10. The system as recited in claim 1, further comprising a battery system for providing power to the electronic audio equipment.11. A portable entertainment system, comprising:a housing unit comprising an equipment enclosure and a speaker enclosure;an audio system comprising electronic equipment and a first pair of speakers coupled to the electronic equipment, the electronic equipment supported within the equipment enclosure and the first pair of speakers substantially enclosed within the speaker enclosure;a support structure dividing the speaker enclosure into a first substantially enclosed section and a second partially open section, wherein the first pair of speakers is affixed to the support structure such that a first portion of each speaker is exposed to the first substantially enclosed section and a second portion of each speaker is exposed to the second partially open section;a first pair of audio ports extending through the housing unit into the first substantially enclosed section of the speaker enclosure; andat least a second pair of audio ports extending through the housing unit into the second partially open section of the speaker enclosure;wherein, when movement of the first pair of speakers in response to electrical signals from the electronic equipment compresses air in the first substantially enclosed section, the compressed air flows through the first pair of audio ports; andwherein, when movement of the first pair of speakers in response to electrical signals from the electronic equipment compresses air in the second partially open section, the compressed air flows through the at least second pair of audio ports.12. The system as recited in claim 11, wherein the equipment enclosure includes at least one speaker enclosure.13. The system as recited in claim 11, wherein the audio system includes audio equipment selected from a group consisting of a CD player, and MP3 player and an AM/FM tuner.14. The system as recited in claim 11, further comprising video equipment supported by the housing unit.15. The system as recited in claim 14, wherein the video equipment is selected from a group consisting of a DVD player, VCD player, television and image projector.16. The system as recited in claim 11, further comprising a battery system for providing power to the electronic equipment.
