It can also be completely sealed, and with the proper O-rings or gaskets, made waterproof, sufficient to protect against deep liquid immersion and thereby meeting NEMA Type 6(P). A CNC machined enclosure can be designed to meet NEMA Types 1, 2, 4(X) and 5.

A transmission line loudspeaker is a loudspeaker enclosure design which uses an acoustic transmission line within the cabinet, compared to the simpler.

I recommend reading the articles in the Projects category on box design for further information.įeel free to check out the other calculators on the site as they may provide the results you are looking for. This type of enclosure may not be the most suitable option for your application. The calculator does NOT take into account the effects of placing the enclosure into the listening environment. The formulas used in the calculator create a design that suggests the most maximally flat response in an anechoic environment based on the number of drivers, the thiele small parameters and the allotted dimensions specified in the user’s input fields.

For cabinet volumes of about 50 to 80L, two vents are needed, and for volumes of more than 80L, three or more vents may be required.įigure 2: Aperiodic Speaker Enclosure Additional Aperiodic Loudspeaker Information For enclosure volumes up to about 50L, one vent is generally sufficient. Generally, about 60% of the cabinet volume should be filled with damping material, while being careful to leave an open path from driver to the vent. Enthusiasts of aperiodic enclosures will often compare the performance with transmission line enclosures, in that the design avoids "ringing" effects of ported enclosures, while alleviating the "pressure effect" of a sealed box.Ī typical enclosure is shown in Figure 2. The impedance response of a sealed versus an aperiodic enclosure is shown in Figure 01 below.įigure 1: Impedance Response - Sealed vs Aperiodic EnclosureĪperiodic box designs roll off at about 18 dB/octave. This results in clearer, better defined bass, with more amplifier power and control into the lower frequencies. By allow air to leak from the enclosure, both the frequency response and impedance peaks are tamed. The behavior of a driver is governed by basic principles of physics. A cutaway view of a movingcoil loudspeaker driver typical of modern designs is shown in Fig.
They were originally invented by Kellogg and Rice (circa 1920).

If a driver is placed into a sealed box that is too small, the result will be a high Q, which will cause a peak in the lower frequency response and a high impedance peak. Moving-coil loudspeaker drivers have been in use for several decades. The purpose of an aperiodic design is to allow a smaller enclosure size than would normally be possible in a sealed box. Photograph 2: Scanspeak Flow Resistance Vent Photographs of a Dynaudio Variovent and a ScanSpeak Flow Resistance Vent are shown below. These Aperiodic ports or vents are sold primarily by Dynaudio, (called "Variovents") and by Scan-Speak (called a "flow resistance vent"). The aperiodic enclosure vents the inside of the box to the outside air through a damped ported (a port stuffed with damping material), which is sometimes referred to as an "acoustic resistor" or "resistive port/vent". An Aperiodic Speaker Enclosure is essentially a poorly sealed box (i.e.
