Scott would like to replace his thirty year old speakers for his home theater system. Scott says that it's not uncommon for the "surround" foam to deteriorate and cause the speaker diaphragm to vibrate more than it should. Refoaming a speaker isn't easy, or cheap. Ross says that there are kits out there on the internet, or there are companies that can do it, but it's probably time to get new speakers.
Leo bought a Panasonic Viero GT-50 and he says it's easily the best for smart apps. Social media apps are great and you can even do Skype. Scott agrees. The GT-50 has an audio return channel via HDMI, so he can use surround sound with his Denon receiver. Scott says you need to specify your speakers as "small" in the settings in order to get the low frequencies in the the sub woofer.
David called in and got very geeky about the electronics behind speakers in reference to another caller to the show Saturday. All jargon aside, Leo wanted to know if a low impedance speaker is better than a high impedance one. David said low impedance speakers around 4 Ohms are used mostly in car stereos because there isn't as much voltage to drive them. Home stereos can have higher impedance speakers simply because there's more power available.
Warren's speakers are unpowered. They need an amplifier to power them. He'll need to take the line level out of the soundcard from the back of his computer, which is a mini-jack that will go into his pre-amp. Then that will go into his big powered McIntosh amplifier, which will go into the JBL speakers. He should think of his computer as an aux input.
It's most likely the sound somehow got assigned to something other than the speakers, but there are numerous things that could have happened. Leo suggests a few things to try:
- Open the "mixer" in Windows' system tray
Look for the speaker icon, and right click on that to make sure the sound is turned up and not muted.
