Background I first read about “line array” speaker designs around 2010 and have been fascinated by them ever since. As the name suggests, Line Array speakers consist of an array of identical speaker drivers placed directly beside each other in a long line. Because each speaker driver is so close to the one next to it, the result is constructive/reinforcing interference between the outputs of the speaker drivers. For a traditional vertical speaker configuration, this causes the sound to be more focused vertically (i.e. focused directly in front of the speaker and not toward the floor/ceiling) and more broadly and evenly distributed horizontally (across theRead More →

LG Firmware Update Available Message

Usually a new firmware being made available a good thing. New features are added and bugs are fixed. But this is not the case when you cannot get the firmware update to apply and this message is continually displayed every time I turned on the TV and came up again every 20 minutes while watching TV. It was extremely annoying to constantly be interrupted by a useless message. Around February 2017, my LG 55LV3700 started displaying this message (and blocking the screen) every 20 minutes: “Updated firmware has been released! [Enter button] to update or [return button] to close.” The problem is that, when I hit enter,Read More →

In my quest for the ultimate home theater bass, I’d always felt that my single Velodyne HGS-15 subwoofer wasn’t delivering quite the low frequency experience I was expecting. Visits to local IMAX theater had me jealous. So I set out figure out what was missing. Much of what I learned is included in my other post entitled Ultimate Home Theater Subwoofer Designs, which describes Infinite Baffle and Folded Tapped Horn subwoofers. This post details how I installed an Infinite Baffle subwoofer system in my home theater. I chose an Infinite Baffle subwoofer design because it delivers extremely low frequencies with perfectly flat response. Those low, chair-shaking / chestRead More →

I used to think the only way to get ultimate subwoofer bass was to spend thousands of dollars on a prestigious brand of subwoofer. I thought that people who build their own subwoofers were fringe enthusiasts who cared more about building something than about sound quality. It turns out I was completely wrong. The opposite is true: DIY subwoofers can deliver sonic performance that’s impossible for commercial subs to replicate. Here’s an overview of the two of the most effective subwoofers you can build yourself. Overcoming the Subwoofer Enclosure Cabinet Size Constraint Most commercial subwoofers are focused on achieving the best possible performance from the smallest cabinet size possible. Small cabinet size isRead More →

The single most important factor of a great sounding home theater is the acoustic properties of the room itself. Not the brand of speakers, not the receiver, not the bit rate of the movie soundtrack. Unfortunately, room acoustics is usually the area where most people give the least amount of attention. And I can’t blame them, because it’s a lot more fun to shop for electronics than it is to spend hours messing with acoustic room treatments. But if you want the best sound quality possible, room acoustic treatments are an absolute necessity. It’s almost impossible to get an absolutely perfect room configuration; you alwaysRead More →

I have 3 Panasonic DMP-BDT 220 Blu-ray players and all of them stopped connecting to Netflix at the same time. Although Panasonic seems to be particularity bad, all set top boxes and TVs seem to have occasionally have Netflix connection issues.  Here’s my list of the most common methods of solving those issues. Option 1 – Hidden Menu within the Netflix App to Deactivate your Device: this should work for any device as Netflix requires every manufacturer to include it. Please note that this does not deactivate your Netflix account itself, just your device, requiring you to log on again. Open the Netflix app on the device OnceRead More →

4k resolution televisions are now widely available and potential buyers are wondering if the extra resolution is worth it. In some cases it is, but in most, it’s not.  The details below can help you decide. 4K (and 8K) Resolution Defined The older 1080p HDTV standard has a resolution of 1920×1080 (2.1 million) pixels. The UHD resolutions are multiples of this base 1080p resolution. 4k resolution is named for the approximately 4,000 (4k) pixels that make up the horizontal resolution across the image. More specifically, the resolution is 3840×2160, which gives 8.3 million total pixels – 4 times that of 1080p. (4k is sometimes calledRead More →

If you want the absolute best sound quality from your digital music files, they need to be bit-perfect rips from CDs stored in a lossless compression format. I recommend using dBpoweramp Music Converter (dBmc) to do this. This page describes how to configure dBmc (version 12 or 13)  for the most accurate bit-for-bit perfect backup of an Audio CD (compact disc). First, you will need to install the following dBpoweramp files: Install dBpoweramp CD Ripper and Music Converter.  You will need to use either The PowerPack Version ($24; 3-week free trial) or the Reference version ($36; 3-week free trail.) I use the PowerPack version. InstallRead More →

I was performing a search on Google Images and noticed a picture of my flat panel TV install, which I detailed in this post. The funny thing was that the image wasn’t hosted on my server. I was surprised that the installer not only was using a copy of my image, but was also claiming to have performed the installation.  Here’s a PDF of the webpage. This demonstrates questionable ethics, by the web designer if not by the company itself. Update: An employee of the business contacted me.  Their web designer used the photo without permission from the business owner, who didn’t monitor the siteRead More →

I’ve created stand-alone clips for demos in my home theater.  Instead of switching discs and skipping chapters, I’ve created/edited video files that are stored on my media server and played-back using a Home Theater Personal Computer. I think the ideal demo scene is comprised of the following: lots of action some setup before the action so viewer isn’t lost or thrown-into the action too abruptly some humor and of course, great audio and video Here are some of my favorite demo scenes. Most are edited clips taken from my Blu-ray disc backups, but some are (still) standard-def versions from DVD backups. Serenity: Firefly takes onRead More →
