ABSTRACT:
A high mass speaker enclosure having a speaker mounted to a front escutcheon plate and below which a multi-gated balanced acoustical transmission yoke is mounted and whereby a portion of the enclosure's interior air pressure is relieved so as to augment the speaker sound, especially at frequencies below 60 hertz. Enclosure resonance is minimized via the use of a high mass enclosure and the filing thereof with a fiberglass material around the speaker and a Dacron filler around the transmission yoke, while front mounted polyester mats preload the speaker and transmission yoke. Speaker resonance, lost sounds and/or extraneous speaker induced sounds are thereby avoided.
