The slot size, shape and what is behind it (the cavity) offer design variables that can be used to tune performance. Consider an infinite conducting sheet, with a rectangular slot cut out of dimensions a and b, as shown in Figure 1. If we can excite some reasonable fields in the slot (often called the aperture), we have a slot antenna. Figure 1. Here's my slot ported wedge. About 1.5 cubes net on one of the newer type R 12's. The things on top are the port and a tray to keep groceries or anything else from falling in front and damaging the sub.

It's interesting to note a few basic factors that still fuel the sealed vs. ported issue, even today. At low frequencies, increasing SPL requirements demand ever-greater woofer excursion from a sealed system, which limits output and can increase distortion. In a properly tuned vented system, the port is providing the majority of low-frequency. Calculate Volume of Box (V) Dv = Diameter of Vent. Np = Number of Port (s)s. fb = Tuning Frequency. Lv = Length of Vent. k = End Correction Factor. Vb = Volume of Box. Dv Centimeter Meter Foot Inch.

Overview: This is a calculator for designing a L-Slot Vent Bass Reflex Enclosure. 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.. With slot ports the farther away from square you get, the less efficient your port becomes. It starts acting like its smaller than it actually is. For example a 1:5 ratio port is only going to flow 81% as much as a square port would of equivalent area. A 1:9 ration port will only flow 73% as much.

Global O-Ring and Seal has developed o-ring groove design and gland dimension guidelines. These are intended for use in basic design consideration and to understand the core principles involved in o-ring gland/groove design. Numerous factors go into the appropriate design of a gland/groove including but not limited to static or dynamic. A 6" woofer in a big box at 10 watts will have a much lower port velocity per given port size than an 18" high excursion woofer in a medium box driven at 1500 watts. A round port has the lowest surface area (perimeter) per given port area. For a slot port, the more equal the sides (a square being optimal) the lower the wall surface area.

Here is the formula we use: ( (14630000* (D/2)* (D/2))/ ( (Fb*Fb*Vb*1728)- (1463* (D/2)))) Please compare your answers with other programs that include other allowances such as tapered ports.

The ports relieve the pressure in the box and make it easier for the woofers to move. The ports push air out when the woofers move back and suck air in when the woofers move forwards. The ports 'fire' sound out in whichever direction they face - so rear ports need a wall behind them to bounce the sound back to you. Fold the port up inside the box. For a conventional looking sub, you can try this arrangement. Do your measurements carefully to leave room for the driver and amp. Here a shelf brace doubles as a bracket to hold the ports. This is a box with an internal height of 680mm containing a pair of 823mm vents. See more on the Snorky sub. The solution is to use flares to allow higher airspeeds before turbulence sets in. For an unflared port, you need to stay below 10 m/sec whereas adding a 35mm flare to an 86mm port lifts the acceptable speed @30hz from 7 m/sec to around 22 m/sec. Pipe mode resonance. As the port gets longer, the resonant frequency of the port decreases.
