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.
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.
When properly designed, a port that is of much smaller diameter than the main pipe located at the end of the pipe then produces the driver's backward radiation in phase with the speaker driver itself; greatly adding to the bass output. Such designs tend to be less dominant in certain bass frequencies than the more common bass reflex designs and ...
The most recent VMPS speakers were a three-way design that featured ribbon drivers for the mid-range and tweeter. The high bandwidth of the mid-range "Neopanel" complemented the use of first-order filters. Woofers were used for bass and mid-bass, along with a passive radiator or port for the 626 bookshelf model. The "RM" in the speaker name (e ...
Moving iron speaker. The original loudspeaker design was the moving iron. Unlike the newer dynamic (moving coil) design, a moving-iron speaker uses a stationary coil to vibrate a magnetized piece of metal (called the iron, reed, or armature). The metal is either attached to the diaphragm or is the diaphragm itself.
The two most common types of speaker enclosure are acoustic suspension (sometimes called pneumatic suspension) and bass reflex.In both cases, the tuning affects the lower end of the driver's response, but above a certain frequency, the driver itself becomes the dominant factor and the size of the enclosure and ports (if any) become irrelevant.
The first amp in Ampeg’s Portaflex series was the B-15, a 2-channel tube amplifier with per-channel volume controls and shared Baxandall-type tone control, housed within a ’flip-top’ tuned-port cabinet design mounted to a dolly. Shortly after the B-15’s introduction in 1960, it became the most popular bass amp in the world.
