A bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses a port (hole) or vent cut into the cabinet and a section of tubing or pipe affixed to the port. [1] [2] This port enables the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies ...
[1] [2] Acoustically, TL speakers roll off more slowly (less steeply) at low frequencies, and they are thought to provide better driver control than standard vented-box cabinet designs, [3] are less sensitive to positioning, and tend to create a very spacious soundstage. Modern TL speakers were described in a 2000 review as "match[ing] reflex ...
The term loudspeaker may refer to individual transducers (also known as drivers) or to complete speaker systems consisting of an enclosure and one or more drivers.. To adequately and accurately reproduce a wide range of frequencies with even coverage, most loudspeaker systems employ more than one driver, particularly for higher sound pressure level (SPL) or maximum accuracy.
Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4-inch (10 cm) woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple 18-inch (46 cm) or even 21-inch (53 cm) speakers in huge enclosures which are designed for use in ...
This suggests that an acoustic suspension loudspeaker with the same enclosure volume and low-frequency −3 dB cut-off as a vented-box system will be up to 2.9 dB less sensitive than its counterpart. If the reference efficiency and cut-off frequency of the two systems is the same, then the enclosure volume of the acoustic suspension loudspeaker ...
The expression / can be replaced by the value 9.523×10 −7 s 3 /m 3 for dry air at 25 °C. For 25 °C air with 50% relative humidity the expression evaluates to 9.438×10 −7 s 3 /m 3 . From the efficiency, we may calculate sensitivity, which is the sound pressure level a speaker produces for a given input:

Since launch, Monitor Audio has operated with in-house design and technology teams. [3] Technologies brought to the market by Monitor Audio include: C-CAM Drivers: C-CAM stands for Ceramic-Coated Aluminium/Magnesium. [4] Conventional speaker cones are liable to flex in operation, which can result in a significant level of audible distortion.
