How Does a Compact Subwoofer Generate Room-Filling Bass – A Technical Study

A subwoofer is a loudspeaker that reproduces low end sound frequencies between 20 to 200 Hz. It consists of one or more woofers mounted in a sealed or ported wooden or MDF (medium density fiberboard) subwoofer enclosure. It can have a built-in amplifier or be driven by an external one. A typical subwoofer is an active speaker with one or more 8 to 15 inch drivers. It has an electronic crossover with a low-pass filter to screen out high and midrange frequencies. The crossover might also have a high-pass filter to prevent low frequencies from entering the main speakers which are not designed to handle bass. Passive subs are a little less common.  

In this article we are going to talk about a specific kind of subwoofer, the compact subwoofer. It is a shallow-height device used mostly in automobile applications. It has a slim space-optimized housing and easily slides under car seats for discrete installation.

Normally, to produce bass a speaker has to move a lot of air and that is made possible by the large sizes of both the woofer and the enclosure. Compact subwoofers such as underseat subwoofers are smaller and lack the advantage of extra space inside the enclosure. So how do they generate room-filling bass?

How does a compact under-seat subwoofer work?

The concept of a compact subwoofer was popularized by audio maker, Sunfire. It has a wide selection of subwoofers with 9-, 11- and 13-inch drivers that deliver high-output bass from compact housings. One of its pioneer compact subs, the True Subwoofer, consists of a high-excursion long-throw driver inside a diminutive enclosure. The terms high-excursion and long-throw indicate the distance a speaker cone moves in and out when pumping out bass. The device, developed by Sunfire founder and legendary sound expert, Bob Carver, is fitted with a 10-inch woofer with an extra-long 2.5-inch excursion (which is about five times that of a standard 15-inch woofer), and a passive bass radiator which is similarly configured.

Due to the high cone movement, the company had to design new surrounds, voice coils and suspensions that would better support the active driver. Even the magnet structure is bigger and weighs 14 lbs. The tamilrockers passive radiator of the device is not connected to the amp. Todaypk does not have a voice coil and magnet. Instead, its diaphragm is tied to a 1.8 lbs weight and moves in response to the back-pressure generated by the active driver’s movement. The passive radiator functions like a vent in a bass-reflex enclosure, but provides comparatively higher tuning range. 

The True Subwoofer is equipped with an active and passive crossover for channeling low frequencies into the sub. It has a control panel for quick adjustments. It has a high-quality MDF enclosure that is smaller than regular sub enclosures. Now, the problem with a small enclosure is that movierulz creates a lot of air pressure inside it which can be hard to overcome. But in order to stay compact and fit narrow spaces, the company could not increase the size of the box. To resolve this issue, Carver developed a hyper-efficient amplifier built around a Tracking Downconverter which is basically an amplifier that monitors transient power requirements. The high-power amp is mounted to the back of the control panel inside the box. It delivers exceptional power into low-impedance loads without overheating. For example, it can generate 2700 watts for a 4 ohm load quite comfortably. For a conventional subwoofer, 2700 watts is a lot and can cause serious damage to the speaker. But tamilmv , tamilgun or an under-seat sub can handle it without any repercussions. 

A compact sub is essentially an all-in-one system with one or more woofers, an integrated high-power amplifier and crossovers, all mounted and wired inside a single speaker cabinet. It contains a specially developed high-excursion long-throw woofer cone for better bass reproduction. katmoviehd has custom-made surrounds, suspensions, magnets voice coils.

An under-seat sub is best suited for vehicles that do not have much truck space or rear area behind the backseat. It is easiest to mount under seats due to its shallow profile. For instance, the JBL BassPro, filmora key a leading car under-seat subwoofer, is less than 3 inches tall and comfortably slides under the driver or passenger seat.  If you want to get more reviews about your products, then read the article on this temple run 2,

Five Steps to Creating an Amazing Minecraft Server

Minecraft has evolved into a popular game that is played by countless fans around the world on several Minecraft servers. If you plan to start Minecraft server hosting, here are some important tips to make your server stand out from the rest.

Develop an interesting theme

Choosing a theme is very important when it comes to making the ideal server. It is important to conduct some research to find out which themes are popular among players worldwide. It is also possible to add a variety of themes that more players can enjoy. Worlds separated by themes will increase your chances of landing more players in your server, thanks to the flexibility in gameplay.

Renting a server

A good server will probably cost money but will be necessary if you want to make an awesome Minecraft server host. Your PC can probably support you and a couple of friends, but if you want to have a community with hundreds of people, you need a server that can perform well 24x7. These can be expensive, but you get a good interface with which to set up and customer service will help you fix problems as and when they arise. It is also a good idea to buy your own domain once your server has reached a certain level of popularity.

Design an unforgettable spawn area

The first thing that players will see when they join your server is your spawn area. Having a creative and attractive spawn area will increase chances of players exploring your server since it's their first impression of your server. The server rules can be placed in signs in the spawn area or a plugin can be installed to make sure users read the server rules before playing in the server.

Choosing and installing your plugins

Once you've figured out what kind of server you want, you need to install some plugins. There are a few basic plugins every server should have in order to make it safe and convenient for the players. This makes Minecraft server hosting much easier.

PermissionsEx: It gives you the ability to create permissions for players. You can make member groups and guest groups for players old and new that will give them the ability to play on the server and you can create an admin group for the people who will be in charge. You can make other groups too, depending on your requirements.

Essentials: These are basic requirements for any server. Essentials Spawn comes highly recommended for setting up your server and also to assign you re spawn areas. Essentials Chat for text formatting is another reliable option.

WorldEdit: Takes some getting used to, but helps a lot with the ability to quickly delete and add spaces and structures. It even has a copy paste option.

Advertise

After all the above steps are finished, you should start advertising your server in Minecraft forums. Your first priority for advertising would be the official Minecraft forum and then others. Give the forum users something to look at by designing attractive custom banners and installing a listener. A listener rewards user who voted for your server by gifting them in-game money and items.
