<p>The disclosure is a high fidelity sound-producing system that has two substantially similar full range drivers capable of accepting energy and producing sound with tolerable distortion over the entire frequency range and one low range driver of appreciably more sound radiating area than the two full range drivers. The low range drive and the full range drivers are in one enclosure and connected across the amplifier output. The low range driver resonates at a similar frequency to the full range drivers and the efficiencies of said drivers are matched to provide substantially uniform sound level output over the frequency range of interest.</p> |
