Tri mode speaker connection is a configuration in which a subwoofer is bridged onto the amplifier and stereo speakers are connected independently to the left and right channels. In the diagram below, the larger speaker is bridged onto the amplifier. The smaller speakers are connected in a stereo configuration. Note that there are no crossovers. Simple first order passive crossovers will be shown in following pages. This is only to show the connections between the speakers and amplifier. Without crossovers, this is not a practical way to connect speakers to an amplifiers. Even with crossovers, it's not really practical due to the cost of the passive crossover components and the limited headroom operating an amplifier in full range mode.

This site was started for pages/information that didn't fit well on my other sites. It includes topics from backing up computer files to small engine repair to 3D graphics software to basic information on diabetes.
This site introduces you to macro photography. Macro photography is nothing more than the photography of small objects. It can take quite a while to understand the limitations associated with this type of photography. Without help, people will struggle to get good images. Understanding what's possible and what's not possible makes the task much easier. If you need to photograph relatively small objects (6" in height/width down to a few thousandths of an inch), this site will help.
If you're interested in air rifles, this site will introduce you to the types of rifles available and many of the things you'll need to know to shoot accurately. It also touches on field target competition. There are links to some of the better sites and forums as well as a collection of interactive demos.
This site helps anyone new to computers and anyone with a basic understanding of computers with a desire to learn more about the internal components of a computer. If you have a computer that you'd like to upgrade but don't know where to start, this is a good site for you.
