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).
A common use of Thiele/Small parameters is in designing PA system and hi-fi speaker enclosures; the TSP calculations indicate to the speaker design professionals how large a speaker cabinet will need to be and how large and long the bass reflex port (if it is used) should be.
These designs can be considered a mass-loaded transmission line design or a bass reflex design, as well as a quarter wave enclosure. [39] Quarter wave resonators have seen a revival as commercial applications with the onset of neodymium drivers that enable this design to produce relatively low bass extensions within a relatively small speaker ...
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 name IMF was adopted because Bud Fried had demonstrated the first prototype speakers at the New York hi fi show, and because of the publicity and the fact that he had used his name on the then unnamed speakers, we stuck with the name which was a mistake on our part. It was never his company. After our lawsuit he called his speakers Fried. [7]
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 was a 26-watt tube amplifier with a single 15" speaker. In 1954, the Bassman was redesigned to use four 10" speakers. This speaker cabinet was an open-back design; as such, it had poor low-frequency efficiency and was prone to blowing speakers when used for bass because of the lack of damping.
