Understanding the Differences between HDMI VersionsHDMI has changed versions so many times it's been hard to keep up for most people. We've talked about the versions as part of other articles and documents, but it seemed fitting that we'd formulate and maintain a definitive document outlining the changes in a straightforward and easy-to-digest manner for all concerned. Hopefully this article helps you understand the format differences and aids in your ability to discern what features are important to you as you shop for HDMI-equipped products. |

The WT3 Woofer Tester by Dayton Audio is a fast, accurate and affordable measurement tool that’s about as easy to use as it gets. Just load the included software, plug the probe into the nearest USB port, calibrate, and you’re good to go. It’s that simple! It’ll measure driver impedance and derive the all-important Thiele/Small parameters - critical to the loudspeaker design process. It will also measure the impedance of various components commonly used in the construction of passive crossover networks such as resistors, caps & inductors. Rounding out this feature set, the WT3 sports some useful extra utilities you’ll likely find handy. All in all, this is one item likely to be a favorite of the DIY community for a long time to come.

When it comes time to size up a subwoofer's performance, the proof is in the measurement! Audioholics takes a hard look at the science of subwoofer measurements in a two-part series covering a broad spectrum of measurement methods, useful to both pro and enthusiast alike. The purpose of both documents are to present a set of measurement guidelines by which a comprehensive objective assessment of a subwoofer’s performance can be developed. Included within this document’s definition of a subwoofer are: single & multiple driver subwoofer systems; powered and passive systems; systems featuring vented or totally enclosed cabinets; along with less common items such as dipole subwoofers. Let the science begin!"

Lately we’ve been getting hit with the common question “what speaker wire gauge should I use”? More often than not, we’ve seen Audiophiles choose a higher gauge esoteric wire over a lower gauge generic zip cord cable simply because they were sold some marketing nonsense that these magic cables would improve your systems mojo. This guide cuts through the nonsense and gives some solid recommendations on selecting speaker wire gauge based on cable length and impedance of your loudspeakers.
