In Reply to: Strengths / Weaknesses of a TL subwoofer? posted by WithTarragon on December 20, 2009 at 08:58:39:
The biggest strength of the TL style enclosure is that the cabinet is inherently very stiff. Physics - wise there are better designs... Duke, below, notes the inherent issues. That leads to hybrid designs such as a damped TL or TL designs terminated either with a port, aperiodic "vent" or PR. One could argue for a given cabinet volume there are other ways to get good low frequency response. Usually the TL design has been used for designed that extend above the Subwoofer frequency range, where the characteristics of the driver are better chosen for bass and perhaps lower midrange, and the TL loading is chosen because the loading parameters of the loudspeaker are not optimized for a reflex or sealed loading - within the other design constraints of the system.
Of course, the marketing power of "Transmission Line" loudspeakers have led to a following in High End, leading to designers specifying their product as TL, when it actually is just a vented box.
