ABSTRACT:
A speaker system is presented. The speaker system has a front speaker driver, a shroud mounted to the front speaker driver substantially encasing a cylinder volume on a rear portion of the front speaker driver. A rear speaker driver having similar dimensions to the front speaker is axially aligned with the front speaker driver and secured at a determined distance behind the front speaker driver and the shroud providing an air gap between the shroud and the rear speaker driver. An acoustically treated enclosure encloses a volume on a rear portion of the rear speaker driver. Electrical connections connect the front speaker driver and the rear speaker driver to terminals for connection to an external driving source such that like excursions occur on the front speaker driver and the rear speaker driver when the external driving source is operable and the front speaker driver functions in an open baffle system.
