For the Alpair 10P-A, this translates to a 2.9" diameter port. c, where c is the speed of sound) at normal listening levels. Commonly, a port area of 0.5.The airspeed in the port should be below 10 m/s (~0.03 On the other extreme, if the port area is too low, the airflow through the port is no longer laminar (i.e. On one extreme, a port area that is too large tends to lead to 'boxy' sound. This tends to be one of those multi-variable problems with many valid solutions.

This works out to a shift of about 5 mm in driver placement. Now both the 'blob' and the 'squirly' (yes, those are the technical terms :)) are gone.

According to Bob Brines, drivers with Qts < 0.35 work better in a straight transmission line. For each taper, work through the design procedure and pick the configuration that provides the smoothest frequency response. With the MathCad programs it is trivial to try the different types of enclosures.
The effective area, Sd, of 88.25 cm² converts to a diameter of 4.2".įor MLTLs, there are three fundamental choices: Tapered with narrow top, straight pipe, or tapered with wide top. Much of the diameter is taken up by the surround and mounting flange. The Alpair 10 is classified as a 6" driver measuring 164 mm in diameter. However, the newly available version with paper/fibre cone piqued my interest. The provide a boost in the mid treble that I don't care so much for. I really liked the sound, though, the metallic cones bother me. I have listened to speakers that used the Alpair 10.3 with metal cones. I happen to have spent quite a while lately drooling over the Mark Audio Alpair 10P-A. It is intended as an implementation of Bob Brines' design procedure as outlined in the " Port placement in a straight MLTL" thread on DIY Audio and a first draft of a speaker design. It is aimed at the DIY speaker designer who is already familiar with MathCad and able to work with Martin J. This page is intended as a "Getting Started Guide" for MLTL design.

For details, as well as other options for how to obtain MathCad, see Martin J. If you do not have access to MathCad, MathSoft makes a MathCad viewer available, which allows you to work with the programs and perform all the needed simulations. King, Mass Loaded Transmission Line (MLTL) speakers are now relatively straight-forword to design for the DIY audio enthusiast. Thanks to a collection of MathCad programs developed by Martin J. However, rather than engaging in a lengthy discussion on naming conventions, I will use the term MLTL to describe a ported quarter-wave enclosure. Now, some may argue that this is a bass reflex enclosure - and the line is indeed a bit blurry. Basically, an MLTL is a quarter-wave transmission line enclosure with a port. There are several types of transmission line enclosures and one of the more popular ones is the mass loaded transmission line (MLTL). Quarter-wave transmission line speakers employ enclosures that are tuned to provide low-frequency extension for the speaker driver. Purifi 1ET400A / Hypex NC500 Input Buffer
