    I'm a total notice to the home cinema thing, and I'm about to ask the most retarded question you'll ever read. What are the benefits of actually having an amp in the first place? Why can't I just hook up the speakers to the sub and the sub to the DVD? Do I actually need an amp?

    At it's simplest An amplifier amplifies the sound and feeds the signal to the speakers. It also does a lot more than that such as switching sources. I am sure others will give a lot more detail. Do you have a tape deck, CD player etc?

    It's only subwoofers for computers that will power additional "satellite" speakers because the amp is actually built into it.

    I don't have a tape deck or CD player, I'm just after a 5 speaker surround sound kit for my television at the moment. I just want to know basically if I NEED an amp at the most basic level - E.G. Can I just add the speakers and sub to my DVD player and it will still all work. I notice the 5 speaker systems don't actually come with an amp usually, so can they work without one?

    Well that's all I needed to know not beforehand knowing a thing about it :D So the 5 speaker systems with a sub will usually be an active sub I guess. Thanks.

    I think the most basic answer to your question is Yes you do need an amp.:lesson:

    The signal from the DVD player is not sufficient to drive the speakers directly, as well some players do not have an analog 5.1 output, thus an AV amp is required to drive the speakers and provide the decoding.

    An amp has therefore several functions, a integrated AV amp usually has a pre-amplifier section (input selection, volume control, decoding / DSP and video switching) and a power amp stage (to drive the speakers).
    An Av receiver has the same functions but provides an additional tuner (radio).

    AE make a little system, its got a small processor which then connects to the sub, the sub then does the amplification for all the speakers. so it does have an amp but you dont have to have a big dedicated amp under your tele.
    its called the aEGO (http://www.acoustic-energy.com/products/aego/aegoloudspeakers.html) might be worth a look.

    Im not sure what this means but the impression I got is that you are left thinking that any speaker system with an active sub doesnt need an amp. It is almost always the case that only cheap nasty speaker systems run off a supplied subwoofer. With more quality items, despite the subwoofer perhaps having an amp, this amp is designed ONLY for the sub, so you then need an amp for the speakers as well.
