Jan 19, 2015 The square port reduces net volume a good amount since it doesn't use already existing walls of the box. The reduced net volume means a longer port to achieve the same tuning. Square port has less surface area than slot port. To figure your port, square/slot/round and different tunings for your box, try here. Select Loudspeakers-101 and then check fro that menu (design port/s) and click on that. Some very basic info is given, and a calculator is their for giving you the deminsions you'ed need for a particular tuning using round, square or slot port/s. Quote Reply Topic: Design of Rectangular ports for a BassReflex Box Posted: 31 March 2011 at 8:09pm. The same thing applies to a narrow slot type port as with multiple ports. The more you move from square the bigger the ratio of surface area to volume. Than cut more wood to make a square ports. But basically as long as the area is.

Rightmost opening on the side of this laptop computer is a Kensington Security Slot
A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of an anti-theft system designed in the early 1990s[1] and patented by Kryptonite in 1999–2000,[2] assigned to Schlage in 2002, and since 2005 owned and marketed by Kensington Computer Products Group, a division of ACCO Brands.[3]
This is where we tell you the casinos and regions in North America that have, for the past year, given their players back the highest percentage of the money put into their slot machines.As we do every year, we first mark the occasion with the story of how the awards—and the concept of “loose slots”—got started. It was 1994 when the magazine first issued awards to the casinos with the “ loosest slots.”Welcome to the 13th edition of our annual “” awards. Our 13th Annual Guide to the Best Slot Paybacks in the Nation by Frank LegatoIt has been a dozen years since Casino Player first gave recognition to the casinos that had shown themselves to be the most generous in the nation. Star casino kansas. Players, in fact, began referring to slots as “loose” or “tight” in response to information first published by Player. Shortly after the magazine published its first issue in 1988, our editors decided to take the information publicly reported by regulatory agencies (only two at the time, in Nevada and New Jersey) on slot “hold” or “win”—the percentage of slot wagers kept by the casino as profit—and presenting it in a way that would be useful to slot players.CP took the reported hold percentages and reversed them to show the “payback percentage”—the percentage of slot wagers returned to the players in jackpots.
Description[edit]
Kensington Security Slot on this portable hard disk drive is marked with a small padlock symbol
The system consists of a small, metal-reinforced hole found commonly on small or portable computers and electronics equipment such as laptops, computer monitors, desktop computers, gaming consoles, and video projectors, combined with a metal anchor attached to a rubberized metal cable secured with a key or combination lock. The end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a heavy table or other similar equipment.[2]
The hole is found in most laptops, although a lock for it is typically not included. Occasionally, the slot is located so that installing a lock will also prevent the removal of a valuable subcomponent, such as a rechargeable battery or a memory module. The Kensington slot may be marked with a small icon that looks like a padlock with a capital 'K', or the slot may be unlabelled.

This will give you a slightly lower required amount of port area. 12.2 sq inches in my example. Like I said, 30 m/sec is the max I like to see. The slot port offers you the largest amount of port area that consumes the least amount of baffle board space. By definition, a slot port uses three cabinet side walls to enclose it's air volume. The fourth wall is the inner port wall. The correction factor for slot port total length is 1/2 the height, added to the port length.

Security[edit]

Kensington locks are not designed to be an impervious protection measure.[3] Because most computer equipment cases are generally made of plastic or thin metal, the lock can be torn out, though not without doing significant visible damage to the case. The cable itself can be cut if an individual has a wire cutter or bolt cutter sufficiently strong to cut through the cable material, which will vary between different brands of cable. The Kensington type locks are useful to discourage quick grab-and-run thefts of equipment from casually supervised locations such as coffee shops, but cannot prevent the removal of equipment secured in an unattended location.

The key is often a cylindrical type, but there are versions which use a traditional flat key. There are also versions of the lock that use a numeric combination instead of a key.[3]
Alternatives[edit]
Several manufacturers offer similar locking mechanisms that do not require a special lock hole.[4] They attach to a popular port, such as the VGA or printer port, and have special screws to secure locks in place.
