Home Theatre System Using Laptops 37

Posted by samzenpus from the because-you-can dept.
Ben Falkon writes "This article takes a look at the possibility of turning a set of laptops into a home theater system. Considering Nelson Chang and the team at HP have had success with running projector party, I don't see why this is not possible. The only problem that I can see is that laptop speakers tend to be weak — then again, modern laptops are gradually being fitted with powerful speakers in these days, so that does not bother me much. A comprehensive discussion follows at the end of the article."

    $200 - $400 amps have better sound and that is for a full 5.1 or 7.1 system some even come with speakers.

      I bought a used old 5.1 amp for $80 and two Technics speakers for $90. The system is hooked up to an AMD 3000 with a Gforce 5200 and media portal. I used a haupage remote. This mess is hooked up to a $500 projector (with which I received a free mount and screen). I have it set to 80" diagonal and it works perfectly. I've had it for over a year now and only used it 470 hours(Apparently, I thought it was a lot more). It's got a Wii and dvd also connected to it. All I'll ever need.

      Yeah true but you can easily sacrifice usability and value by going with the stand alone amp.

    I feel like powerful laptop speakers are not measured on the same scale as powerful normal speakers, meaning powerful laptop speakers would be mediocre to poor home theater speakers, especially with the noise generated.

      I agree. The speakers in my Asus laptop are exceptionally loud compared to most laptop speakers, but they're still awfully quiet even compared to basic cheap 2-speaker sets.

        Also, I don't know about yours, but with mine "loud" = "distorted, tinny, and annoying". They're fine up to ~3/4 volume, but past that--assuming the sounds is cranked up in the software, too--they sound very, very bad.

          I've actually been very impressed at the sound quality on mine, even at the higher volume levels it offers. It's not until I use the software equalizer to force higher volume levels that it starts to noticeably distort and sound bad. Obviously though, they don't have the real bass of a system with a sub, but the sound quality itself is at least as good as the average 2-speaker computer set.

        Speakers have three main desirables:

        • Loud Volume
        • Good Quality / Range
        • Small Size

        Pick two.

          Exactly. And for a home theater system, no one needs option #3. So laptop speakers need not apply.

  • just laying around, old laptops are FOOBAR or donated to 'needy' relatives, and it seems to me latptop speakers will by tinny regardless of how many you stack on top of each other, if something isnt capable of producing base, it doesnt become capable of it just because youve got lots of them.

    laptops are fine for watching media on your own, but they are not a home theater, however they could be a nice low power consumption media center once you plug in a decent screen and speakers

    ... and can I have some?

    /Paraphrase/ Modern day laptops are cost effective because they can be used as laptops when not in the grid \/Paraphrase/

    What? TWELVE (12) MODERN DAY LAPTOPS are COST EFFECTIVE?!! Lets just give the benefit of the doubt that these are only the $800 variety and not the $2500 variety. For $9,600, you can buy an Integra DHC 9.9 pre-processor, a Emotiva MPS-2 multi-channel amplifier, and still have $6000 to buy speakers, and be under the cost of the 12 laptops. Not only that, but you will have all the same benefits and even more, since the pre-processor can accept HDMI v1.3, component, and composite video, and up-convert the video to 1080p to output all on a single HDMI connection to your TV, which means you can use other devices like stand-alone blu-ray, PS3, XBox360, etc., and connect to the system in HD (unlike the laptops). You also will have 200W power for 7 speakers, unlike the 5-10W for the 12 speakers from the laptops.

    So again, what the heck are they smoking?

    • They're smoking GeekWeed :>) You know, the stuff that makes you take items and bend them to a new purpose just for the joy of doing it.

      Me, I think this would be a fun project. Having the LCD's wrap around, and getting it to transition smoothly, plus then getting the sound to wrap around, well, that would just plain be cool. And if you want better sound, just use the audio out port to desktop speakers.

      • That is just it. With this kind of cash, you aren't talking about a theater in a box, you are talking discrete separates, and high end speakers, with things like video upconverters, video processors (stream processing de-noise/artifact filtering), and other high-tech electronics (in other words all kinds of geek'ing out).

        We are also talking "theater" here, which mean BASS... Personally, I have a setup which has 2x10" woofers, 2x8" woofers, 2x6.5" drivers, 24x5.25" drivers, 3x4" drivers, and 7x1" tweeters.
        • Oh and during frequency testing, I found that the house has a fundamental or harmonic mode of 12Hz. Real interesting when playing that frequency and being told that paintings were falling off of walls a floor away (as well as on the complete other side of the house).

        • If they purchased new laptops for this, then it would be silly. I thought that they were theorizing about using old laptops, like corporate laptops that have been retired after two or three years. The batteries are junk and the keyboards worn out, but the displays are still okay. The speakers will be as tinny as ever and the displays would not combine for a perfect surround screen as the bezels will be in the way. Eh, still, just for fun.

          And I agree with your points on making/selecting a proper sound

  • I was just thinking about this the other day. The $379 laptop is often good enough for what I watch, low power consumers and quiet enough to be a HTPC. (and for sound I would plug it into a Home theater system any time I could)

    And then I saw one of the MS Media servers being cleared out and I realized... I would have bought one a few years ago, but that seems like so long ago.
    Nowadays, I could make about any PC into a media server by installing GNU/Linux, and if I was worried about power consumption, I wo

I've been doing it since SoundBlaster 1.0 was released. It's not any harder than plugging headphones into an iPod, for the love of christ. Guess, what, my laptop IS my home theater system. Has been for about a decade. I just have my $1.99 Wal-Mart wire running from my laptop to my amp.

So instead of "specialized home theatre racks," we now need to line the room with book shelves for our 12 expensive, power-sucking laptops, who's fans (if they're Toshiba Satellite Hoovers) are going to contribute a wash of white noise and heat into the room.
