Some help getting over the hurdles

WinISD Pro

WinISD Pro is box-building software. A program that installs on your PC, it will provide you with the tools to design a woofer enclosure. Download it HERE (it is freeware).

The program uses parameters that you input from those provided by the manufacturer, or from measurements you have taken of the woofer. It calculates those parameters and, along with a given amount of box airspace, forms a response that you can expect to get from the woofer. It is just one of several box-building programs that you could use, but it is free and relatively easy to master.

FAQ: "Why do I need a box-building program?"

Most woofers, including subwoofers, need an enclosure in order to work properly. The amount, or volume, of air in the enclosure is critical in how the woofer performs. Using the tools provided by WinISD allows you to see what differences there would be with different air volumes, and lets you adjust the sound to your liking by making changes in the air volume. And it provides the tools you need to design a vented enclosure.

Scope of this tutorial

This is meant to serve as a starting gate for people who like good music in their cars and want to be able to make it better..particularly people who like BASS :...and want the best box possible for their subwoofer(s). It's written to encourage those who have tried to use WinISD in the past and gave up to try again. I will expose the "stumbling blocks" that might have caused some of you to give up on it. I will provide some insights into why the program does what it does, and give some tips on how to use it to your advantage. Links will be included throughout to refer to graphic illustrations or to other sources of information. With help from this guide, a user will learn to correctly input parameters into the program, get past the stumbling blocks, and understand the program's results.

I'm a strong believer in reading Help files and encourage all readers to use the Help section contained in WinISD. Everything I say here is contained there, too, but my experience has shown that a surprisingly large percentage of users don't refer to the Help file to find answers. Some of it could be that they don't understand the program's author, who is Swedish, and his mastery of the English language. And some of it could be that the answer they are looking for is in a different section from where they are searching. But I'll tell you this now: if you don't refer to Help as you are becoming familiar with working in WinISD, this guide will not help you successfully complete your design. You may only have to look up a handful of things, but look there first before asking someone to look it up for you.

It should be known to you by now, if you are a reader of this forum, that the enclosure plays a major role in how your bass sounds. In fact, it is widely regarded as THE most critical part of your subwoofer system. If more enthusiasts got involved in that one extra step in building their sound systems...designing the perfect enclosure...the passion for car audio would reach new heights. This tutorial, and WinISD itself, goes no further than the design of the airspace in the box, and if vented, includes the design of the port. Shape or dimensions of the box are not considered, nor is it known if the woofer will be used in a car, apartment, boat or elsewhere. It is simply (but not so simply!) a tool to see what changes in airspace does. This guide will not cover all the tools contained in the program but I'll clarify or point out the main ones you'll use. It is not a step-by-step approach, but you'll be stepping along just fine if you get off on the right foot.

This tutorial is arranged in sections with titles in bold print down the left column. The sections are, in order from this point:
