Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
A substantially omniquadrant loudspeaker system for the audiofrequency band that comprises a four-sided housing mounting substantially centrally in each of a pair of opposing sides of the housing substantially similar opposing low-audiofrequency loudspeakers, one mounted with its center about one-quarter the wavelength of the mean of the low audiofrequencies above the bottom of the housing and the other mounted thereabove about three-eighths said mean wavelength, and a plurality of highaudiofrequency loudspeakers, at least one asymmetrically mounted off center in each side of the housing near corners at the top thereof.
Claim 2
Dependent Claim
90 words
A substantially omniquadrant loudspeaker system for the audiofrequency band that comprises a four-sided housing mounting substantially centrally in each of a pair of opposing sides of the housing substantially similar opposing low-audiofrequency loudspeakers, one mounted with its center about one-quarter the wavelength of the mean of the low audiofrequencies above the bottom of the housing and the other mounted thereabove about three-eighths said mean wavelength, and a plurality of highaudiofrequency loudspeakers, at least one asymmetrically mounted off center in each side of the housing near corners at the top thereof.
Claim 3
Dependent Claim
26 words
A loudspeaker system as claimed in claim 1 and in which mid-audiofrequency loudspeakers are provided, mounted near corners of said housing sides opposite said high-audiofrequency loudspeakers.
Claim 4
Dependent Claim
19 words
