A speaker assembly includes a speaker housing with a closed top wall that is substantially planar and forms a support surface. A first midrange driver and a first tweeter are mirror images of a second midrange driver and a second tweeter. A first support bracket supports the first midrange driver and first tweeter along a first side of the closed top wall adjacent the first sidewall of the speaker housing. The first support bracket includes a planar support surface which is obliquely oriented relative to a plane in which the closed top wall lies. A second support bracket supports the second midrange driver and the second tweeter along a second side of the closed top wall adjacent the third sidewall of the speaker housing. The second support bracket includes a planar support surface which is obliquely oriented relative to the plane in which the closed top wall lies.
