Do Wires Running to a Pair of Speakers Need To Be the Same Length?

Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com

Q Do all speaker wires running to matched sets of speakers need to be the same length? I’m using 12 AWG wire to connect my AV receiver to speakers with an impedance of 6 ohms. My plan was to use 3-foot runs to my right and center speakers, a 10-foot run to the left speaker, and 26-foot and 36-foot runs, respectively, to the left and right surrounds. Will this create a problem? —Dan Donna / via e-mail

Do You Need AirPlay to Stream Music in iTunes to a Sonos System?

Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com

Q I want a great-sounding home theater system (preferably wireless) that won’t break the bank. I’m interested in the Sonos system (PLAYBAR, PLAY:1 rear speakers, and SUB). The only downside is that Sonos doesn’t support AirPlay—a deal-breaker for me since much of my music is on Apple devices (MacBook, iPad, and iPhone). Someone told me I don’t really need AirPlay to play my iTunes library through Sonos. Is that true?—Paul Fox

Downloading Home Theater Geeks
Scott Wilkinson  |  Jun 16, 2011  | 
I love your Home Theater Geeks podcast; I listen every week. But I can't find a way to download older episodes. They are all available at twit.tv/htg, but when I follow the link to download them from iTunes, all I can see are the most recent 20 shows. I am trying to download episode 25 but cannot because of this.

Downsizing Speakers
Scott Wilkinson  |  May 12, 2011  | 
My current speakers are Aerial Acoustics Model 7Bs, which I have been very happy with. However, I am moving from a 20x16 listening area with a 20-foot ceiling to a senior-living condo with a 14x14 listening area and 9-foot ceiling. In my opinion, the 7Bs will take up too much room and, I believe, are not suitable for the smaller area. I like the Aerial line and would like to keep the sound quality I am used to. I have been thinking about the 6Bs, and I wonder if you have ever listened to them? I have received a few options from some dealers, but I'd like to get your take or maybe some other suggestions you may have.

Dream Home Theater
Scott Wilkinson  |  Jun 17, 2011  | 
What gear would you get if you were building your dream home theater? Let's say you had an unlimited budget for video and $100,000 for audio. What speakers, amp, preamp, projector, and screen would you get? Also what would your surround configuration be? 7.1, 9.2, 11.4? Where would you put the speakers? Would you utilize the back surrounds or front height and width channels?

Dual Center-Channel Speaker Setup
Al Griffin  |  Oct 10, 2013  | 
Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com.

Q I wish to place center-channel speakers above and below my projection screen. I know the distance from the two speakers to the seating position at ear level will not be the same, and I would like to know how to calibrate or compensate for this difference. I have a 5.1 surround setup with an Oppo BDP-105 Blu-ray player, a six-channel amp, and a powered sub. I am patient enough to do the onscreen setup from the Oppo, but I’m at a loss over the dual center speaker issue. —Dale Kay / via e-mail

DVR Hum
Scott Wilkinson  |  Jun 21, 2011  | 
I have a Dish Network Model 722 DVR (pictured above) connected to a Vizio E420VO HDTV via HDMI. When I turn the TV's volume up above 0, I get a slight low-level hum, almost like a 60Hz hum, which does not increase as I raise the volume level. If I turn the volume down to 0, there is no hum. The audio from TV programs is loud enough to mask the noise when listening at a normal volume level. I tried another HDMI cable with no change. It doesn't happen with my LG Blu-ray player; I even swapped the inputs, and the noise followed the DVR. The cables are 6-foot HDMI and not expensive. Everything is plugged into an APC uninterruptible power supply unit, though the hum happens with or without the UPS unit in line with the AC outlet.

Am I making a big deal out of nothing? Should I just ignore it or try to cure this low-level hum?

The DVR provided by Cox only has an 8-hour capacity for storing HD broadcasts. The only alternative I've found is $1000 for an HD TiVo and renting cable cards. Any suggestions?

Dynamic Contrast Blues
Scott Wilkinson  |  May 02, 2011  | 
I have a 40-inch Mitsubishi LT-40164 LED-edgelit LCD TV that I really love but for one thing—the screen darkens dramatically during dark scenes and even during credits when there may only be one or two lines of text on the screen. I have tried tweaking dozens of settings, including full backlight and brightness, but to no avail. Is this normal for LED TVs?
