Abstract
A speaker system comprises a housing that includes a front wall with a plurality of openings, and first and second exterior sidewalls. A plurality of vertically arranged speakers are each placed into an associated one of the plurality of openings and secured to the housing. A hemispherical concave interior wall is positioned in back of the plurality of speakers and within said first and second sidewalls to disperse and attenuate audio waves within the housing. The housing may also include a tuned, dampening bisector that is mounted to the hemispherical concave interior wall positioned in back of said plurality of speakers and within the first and second sidewalls. The bisector is preferably located at the center of the hemispherical concave interior wall. A rear exterior wall defines a back of the speaker system and the front wall defines a front of the speaker system. The first and second interior sidewalls extend from front to back and preferably taper inward from back to front of the speaker system, wherein the first and second interior sidewalls each mate with the hemispherical concave interior wall. The plurality of speakers preferably include mid-range drivers and tweeters. For example there may be two tweeters associated with every mid-range driver. In one embodiment there are for example twenty-one mid-range driver and forty-two tweeters, wherein two tweeter openings are adjacent to an associated one of the mid-range openings. The speakers are arranged electrically in a series/parallel configuration. For example, several mid-range speakers/drivers are arranged in a series configuration to provide a mid-range subarray, and the number of mid-range drivers placed into each sub-array is selected such that the total Q factor for the sub-array is approximately one.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
