January 31 2013, 13:01

We’re now a month into the new year. What types of audio projects have you designed and installed? We’re interested, so send us an e-mail with “audio update” in the subject line and include details about your latest project. We’re interested in tube projects, DIY speaker setups, hi-fi product reviews, and more.

If you haven’t decided on your first 2013 project, you’ll likely get some excellent ideas from this issue. We feature audio product reviews, speaker design tips, and more. Let’s look at the details.
