RMS, HDMI, RGB

More Power!
Years ago, I was told that there were several ways to rate the power output from an amplifier, but only one of those ratings was the "true" measure—RMS or continuous power. The Federal Trade Commission (FTC) got into the act back in the 1970s, requiring all amps over 5 or 10 watts to be rated in RMS watts with both channels driven. That requirement was lifted in the '80s, and now when I read power output specs, I don't know if they are RMS (root mean square), IHF (Institute of High Fidelity), or something else. Could you clarify this confusion?

Going Down
In the measurement section of some speaker reviews, I've often read that a speaker's -3dB point is at a particular frequency and the -6dB point is at another frequency. Could you please explain from what level the speaker is down 3 and 6dB?

Rooftop-Antenna Rotors
Scott Wilkinson  |  Aug 08, 2011  | 
I'm an avid listener of TWiT and have heard you on the Tech Guy and your podcast. Because of TWiT and the fact that I don't watch a lot of TV, I have decided to "cut the cord"—that is, dump cable and satellite. However, I would like to take advantage of digital over-the-air broadcasting. I remember hearing that you have a rooftop antenna with a motorized rotor for orientation adjustments. What options are available for different qualities and prices?

RPTV & PC
I'm planning to buy a 60- or 70-inch HDTV in a few months. The room where it will live is not totally darkened like a home theater. Besides watching TV and DVDs, we also want to hook it up to a PC. With this requirement, is LCD TV the way to go?

RPTVs vs. Flat Panels
Scott Wilkinson  |  Dec 16, 2011  | 
You have the best home-theater website, hands down. I also love your short guest appearance on Leo Laporte's radio show every week. I notice that you talk about plasma and LED LCD TVs a lot, but very rarely talk about DLP TVs. Even last weekend when you were the guest host on Leo's show, there was no mention of it. Is this because the technology and displays are not as good as plasmas and LCD TVs, or is it because there is no market for those TVs? Or is there another reason? I can get the Mitsubishi WD-92840 92-inch DLP TV for about $3300! No plasma or LED comes close to this price. If I want an 80-inch or larger flat panel, I'm looking at somewhere north of $10,000!

RPTVs, Speakers, Aspect Ratios

Defending RPTV
I think you're a little harsh on rear-projection HDTVs. They've changed. For instance, the 67-inch Samsung I bought last year has no lamp and no color wheel. It's lit by three LEDs that fire their color beams directly at the DLP chip. No lamp to replace, no mechanical troublemaker. Also, the picture fully retains its brightness within an arc that is realistic for most home viewing.

Samsung UN46D6000 vs. Panasonic TC-P50ST30
Scott Wilkinson  |  Nov 04, 2011  | 
Can you recommend a TV for a small living room? The room is 18 feet wide, and current viewing distance on a standard-definition 35-inch TV is about 12 feet. I'm looking at the 42-inch size range for $1500 or less. I think I need an LCD TV with 120 or 240Hz refresh rate; I watch a lot of sports, and I'm not sure that 120Hz would be enough. Also, I think I want an Internet connection as well. I know from listening to you that this can update the TV, but can it access shows like what Leo Laporte and you do on twit.tv?

Samsung UN55D8000 vs. Sony XBR-55HX929
Scott Wilkinson  |  Sep 30, 2011  | 
I want to buy a LCD TV with LED backlighting. I am not a "ultimate" kind of guy because I do not have the money. I am looking for a 55-incher for $3500 or less. I've heard you say Samsung is the one to get. What the model would that be? I think it is the UN55D8000.

Satellites, Subwoofers, Projector Placement

We Don't Need No Stinkin' Boxes!
A satellite signal comes into your house and goes to the satellite receiver via coax, right? Why can't you connect the coax directly to an HDTV and get a high-def signal? Also, why do Dish and DirecTV advertise "full HD" when the signal is 1080i?

Screen Size and Seating Distance
Scott Wilkinson  |  Dec 27, 2011  | 
Is there a site that can help determine the right screen size for a given seating distance? In my case, the distance from my couch to the TV is 7 feet.

Goo for God
Have you ever reviewed any paint-on projection screens? If so, how do they generally compare to an actual screen? Also, is there a brand you recommend? I'm thinking about going this route for my church, not a home-theater setup.

Searching for a Sealed Sub to Go with My Maggies

Q I want to add a subwoofer to my Magnepan MG12 speakers in a two-channel-only setup. I am looking at sealed subs to keep up with the pace of the Magnepans. I can budget up to $1,000 but would prefer to spend less. The room is 380 square feet, with the listening area directly in the center. I’ve considered the RSL Speedwoofer Mk II, a Rythmik L12, and the SVS 3000 Micro. Your professional insight would be appreciated. —Craig A.

Searching for an AVR
Scott Wilkinson  |  Mar 09, 2012  | 
I'm upgrading my home-theater system with a Panasonic TC-P65VT30 plasma TV and Oppo BDP-93 Blu-ray player. I also want to replace my Yamaha RX-V793 A/V receiver, but I'm not sure what make and model would be best. I plan to keep my Paradigm Cinema Phantom tower speakers (front left and right), CC-170 center speaker, Atoms (left and right surrounds), and PDR-12 subwoofer.

I'm willing to pay for an AVR that will provide video performance to take full advantage of the TV and Blu-ray player. Likewise with sound performance; I see no point in paying for a higher performing AVR than my existing speakers can handle.

BTW, my room is 18x12 feet, and the TV will be located on one long wall with the sofa along the opposite wall. Also, I have carte blanche from my wife to get what I want in designing the media room.

Seeking Guidance on Vintage Amps and Receivers

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

Q I’m on a vinyl kick. I recently purchased an Audio-Technica LP120 USB turntable and am converting a few of my old LPs. I have it connected to a Sony AVR and am listening through my Klipsch Reference RB-5II bookshelf speakers. Now I’m thinking about searching for a vintage amp or receiver. I’ve read good things about the Marantz 1060 integrated amp (circa 1975), which is rated at 30 watts per channel. I also hear good things about some of the old Pioneer gear. I want to crank old classic rock, and I know the RB-5IIs can handle it. Any suggestions on what I should set my sights on? — Lew Collins/Via e-mail
