Two-inch port tube installed in the top of a Polk S10 speaker cabinet as part of a DIY audio project. This port is flared. Unlike closed-box loudspeakers, which are nearly airtight, a bass reflex system has an opening called a port or vent cut into the cabinet, generally consisting of a pipe or duct (typically circular or rectangular cross section).
This article lists manufacturers of bass amplifiers, loudspeakers, and other amplification-related items such as preamplifiers. The amplifiers and loudspeakers used to amplify bass instruments (e.g., the bass guitar, double bass and similar instruments) are distinct from other types of amplification systems due to the particular challenges associated with low-frequency sound reproduction.
The "301" bookshelf speakers were released in 1975. The Bose 301 Series II is a direct/reflecting speaker system. It includes “bass effects” through a 8-inch woofer and surround sound effects through its asymmetrical design. Dual frequency crossover network in the Bose 301 Series II improves sound clarity by optimizing output frequencies. [30]
This model soon became the SM-400. SWR then pursued development of a speaker cabinet to accompany its amps. In 1986, SWR released the Goliath, a 4 x 10" full-range speaker cabinet with a built-in horn tweeter, a first for bass cabinets. The company's name was changed to SWR Sound Corporation on 1 December 1997 as part of a restructuring plan.
The first model offered was the Super 800, an 18-watt model with a single 12" speaker and a rear ventilation port. In 1951, Ampeg introduced a 20-watt version with a 15-inch speaker. In 1960, they introduced the B-15 Portaflex, a flip-top 25-watt tube bass amplifier with a single 15" speaker.
coupled-cavity bass loading (Model 104/2, 1984), a technique of pairing two bass drive units and feeding their output via a single port; conjugate load matching (Model 104/2, 1984), a crossover optimisation technique that presents a constant (albeit low) ohmic load to the amplifier; the "KEF Universal Bass Equaliser" (aka "KUBE") (Model 107 ...
Thiel Audio first exhibited at the Consumer Electronics Show in 1977 (the year the company was commonly stated as being founded, although they had been selling since 1976) [5] with the introduction of the 01 full-range speaker. A year later, in 1978, the model 03 introduced the principles of time, phase, and frequency coherence, which would ...
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
