tube and the inner tube. The sound wave reflecting member, the outer tube, and the inner tube cooperatively form a resonator. The resonator communicates with the resonance chamber and the back bass port. Independent Claims 1. A speaker system, comprising: a loudspeaker; an enclosure defining a resonance chamber, the enclosure comprising a front panel and a base, the loudspeaker received in the resonance chamber and exposed at the front panel, the base comprising a back panel opposite to the front panel, an inner and an outer tube, the back panel defining a back bass port, the inner and the outer tubes extending from the back panel and received in the resonance chamber, the inner tube surrounding the back bass port, the outer tube surrounding the inner tube; and a sound wave reflecting member comprising a bottom panel, an outer barrel, an inner barrel defining a first receiving room, and four boards, the outer barrel, the inner barrel, and the four boards extending from the bottom panel, the inner barrel received in the outer barrel and coaxial with the outer barrel, the inner barrel and the outer barrel cooperatively forming a second receiving room there between, the four boards substantially equidistantly spaced from each other around a center of the outer barrel, each board extending from an inner surface of the outer barrel and passing through the second receiving room to the first receiving room, the sound wave reflecting member coupled with the outer and inner tubes, the first receiving room receiving the inner tube, the second receiving room receiving the outer tube, the sound wave reflecting member, the outer tube, and the inner tube cooperatively forming a resonator, the resonator communicating with the resonance chamber and the back bass port. 12. A speaker system, comprising: an enclosure defining a resonance chamber, the enclosure comprising a front panel and a base, the base comprising a back panel opposite to the front panel, an inner and an outer tube, the back panel defining a back bass port, the inner tube and the outer tube extending from the back panel toward the front panel and received in the resonance chamber, the inner tube surrounding the back bass port, the outer tube surrounding the inner tube; a loudspeaker received in the resonance chamber and exposed at the front panel, the loudspeaker configured for generating sound waves toward the resonance chamber; and a sound wave reflecting member positioned between the front panel and the back panel in the resonance chamber and coupled with the outer tube and the inner tube, the sound wave reflecting member, the outer and inner tubes cooperatively forming a resonator, the resonator communicating with the resonance chamber and the back bass port, the sound waves first reflected by the back panel toward the resonator, and then passing through the resonator, and finally propagating out of the enclosure through the back bass port.
