And like M5 said, most of it causes more harm than good. Seriously, alot of this stuff people are posting is pulled out of thier asses. goals and personal preferance comes to play. We are talking about itin another thread, 10th's are indeed louder, just not to the ear. There is truth in the glass, but how much louder is what comes to play. Perhaps to one specifically designed enclosure and one specific subs specs, with a specific tunning and power, but not in everycase. X-max has so many other values that intertwine, it can not truly be narrowed down to a general statement. I have been trying real hard to read up on the t/s specs and learn all their values. The thing on the x-max, i have read that, and with the same confident reviews, i have read that installing a sub into a t-line will reduce it' power handling. With car audio, like the nich i happen to fall into, daily driver, hip hop and rap style music. I searched the net over, found so many facts and figures, extremly ellaborate builds, on both sides of the spectrum. What one is right or wrong, there is where you will end up, personall preferance and goal. Sound, output, both style enclosures have been designed, built and documented as having great results. ease of design and build, mentioned and considered alot. You will find, when done right, that either can deliver satisfaction to a specific set of goals. Your personal preferance and goals will begin to override all input toward the end of your research. The Acoustic-Structure Boundary multiphysics coupling is used to connect the different acoustic and structural physics and the Acoustic BEM-FEM Boundary multiphysics coupling is use to couple the interior acoustics to the exterior at the vent.You will find two large crowds on this subject. The acoustic cavity within the enclosure is modeled with the Pressure Acoustics, Frequency Domain physics, while the infinite domain surrounding the enclosure, is modeled with the Pressure Acoustics, Boundary Elements physics. The model represents the structural components through the Solid Mechanics and the Shell physics applied to the different parts of the loudspeaker (enclosure and driver).
#Speaker enclosure design ported transmission line driver
The electromagnetic properties of the driver are supplied from the Loudspeaker Driver - Frequency-Domain Analysis tutorial model. The directivity is assessed using the Directivity plot and represents the spatial sensitivity plotted against the frequency in a contour-like plot. The sensitivity is commonly defined as the on-axis sound pressure level, measured at a 1 m distance. Two of the most important design parameters for a loudspeaker driver is its sensitivity and the directivity of the system. The enclosure, sometimes called the cabinet, alters substantially the sensitivity and radiation characteristics of the loudspeaker and it is why it is usually considered part of the integral design of a loudspeaker system. This tutorial models the acoustic behavior of a loudspeaker driver mounted in a bass reflex enclosure.
