In particular, the basic parameters and equations describing sealed and reflex designs are fairly well understood, the range of options involved in a transmission line design mean that the general design can be somewhat calculated but final transmission line tuning requires considerable attention and is less easy to automate.
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).
Often designated by the CVBS acronym, meaning "Color, Video, Blank and Sync". RCA jack, normally yellow (often accompanied with red and white for right and left audio channels respectively) S-Video (Separate Video). Carries standard definition video and does not carry audio on the same cable. Mini-DIN 4-pin Component. In popular use, it refers ...
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.
Passive radiators are used instead of a reflex port for several reasons. In small-volume enclosures tuned to low frequencies, the length of the required port becomes very large. [5] They are also used to reduce or eliminate the objectionable noises of port turbulence and compressive flow caused by high-velocity airflow in small ports.
Generally, line level signals sit in the middle of the hierarchy of signal levels in audio engineering. There are weaker signals such as those from microphones (Mic Level/Microphone Level) and instrument pickups (Instrument Level), and stronger signals, such as those used to drive headphones and loudspeakers (Speaker Level).

Loudspeaker acoustics is a subfield of acoustical engineering concerned with the design of loudspeakers. [1] It focuses on the reproduction of sound and the parameters involved in doing so in actual equipment.
