Abstract
Abstract A speaker system, comprising for each of its channels, a stand supporting a midrange unit, from the housing of which a plurality of tubular supports emanates radially and equidistantly, a tweeter unit mounted on the free end of each of the tubular supports, one self-contained lowrange (bass) commode containing a woofer unit, respectively for each of the channels: a cross-over network separating and feeding the various frequency ranges to the midrange, tweeter and woofer units.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
In a stereo speaker system, operable by way of a crossover circuit, comprising: (a) an elongated stand; (b) a housing of hexagonal configuration mounted on top of the stand; (c) means for reproducing midrange frequency sound signals accommodated within the housing; (d) a plurality of tubular sections mounted on and extending radially outward from the sides of the housing; (e) a plurality of means for reproducing high frequency sound signals, mounted on the outer ends of the tubular sections, respectively; (f) means for reproducing low frequency sound signals accommodated separately from the means for reproducing midrange and high frequency signal sounds; (g) a crossover circuit wired for separating and delivering the appropriate range of frequencies to the means for reproducing the midrange, high and low frequency signal sounds, respectively.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
A speaker system, according to claim 1, wherein four tubular sections radiate from and form 90° angles with the sides of the housing from which they, respectively, extend.
Claim 4
Dependent Claim
20 words
A speaker system, according to claim 2, wherein the tubular sections are mounted detachably on the sides of the housing.
Claim 5
Dependent Claim
147 words
A stereo speaker system operated by way of a crossover network, comprising for each channel: (a) a base including a tubular section extending vertically upward therefrom; (b) a hexagonally shaped midrange speaker mounted on the free end of the tubular section; (c) four tubular sections mounted detachably to and extending radially and equidistantly, respectively, from center portions of the side surfaces of the midrange speaker so as to form 90° angles therewith; (d) four tweeters mounted respectively to the free ends of the tubular sections; (e) a woofer accommodated separately from the midrange speaker and tweeters; (f) electric wiring means extending through the base to the midrange speaker, the tubular sections radiating from the midrange speaker to the tweeters, and to the woofer delivering, by way of the crossover network, mid, high and low frequency sound signals for reproduction to respectively, the midrange speaker, tweeters and woofer.
