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.

Abstract: A two-piece, separable electrical connector adapted to couple mating parts of the various components used in high fidelity stereo equipment or the like. The first element comprises a male plug member formed from a block of conductive material and having a generally tapered frusto conical portion extending from one end of a cylindrical segment having opposed flat surfaces formed thereon. A threaded bore is formed axially through this cylindrical member so as to receive a bolt, the bolt being used to secure an electrical cable to the connector member. The second element of the connector is a female member comprising a generally cylindrical conductive piece having a longitudinal, smoothly tapered bore extending inwardly from one end surface thereof. Formed in the opposite end surface is a threaded bore which, too, is arranged to receive a bolt for attaching an electrical conductor to the female element.
