Best Complete HomeTheater USED for $5000.00

Without first knowing your room size and setup options, I probably vote you just add a dedicated AV processor (even an inexpensive Acurus ACT 3 would more than suffice...more than good enough for movies, very dynamic/clear) for movies, a subwoofer, and be done with it!!!! You won't need drastic setup changes, nor a radical trasformation.
On the other hand, er, what's your room like?!

From saffy

Say I got the best used projector under 2K, with a pull-down screen.

Kept my previously mentioned 2-channel system as is - but added an AV processor.

Questions:

-What speakers would I need to add / if any?(Sub-center- Rears)
-How would I connect the AV to my Jadis integrated??
-My Theta DVD does not have Proscan - is that an issue?

My room is approx: 15 x15'

Thank you

With a none-pro scan DVD, I doubt you will like the results, you will get a "screen door" affect. The pixel will probably be very visible unless you are fairly far back, but it may work.

As for speakers, pay close attention to the center it works the hardest, dont skimp here.
Are you using existing speakers for front L/R? If not do you want full range floor standers or monitors?

5.1 or 7.1? 6.1 is a bad idea, only 1 speaker in back will give you cancelation problems.
Another thing to think about is a standard mono-pole speaker, or a wider sound of a bi, or di-pole for surrounds
I would have to say a sub is a must, but if you are ever going to want to get into SACD or other multu-channel music you may want to look into a "fast" sealed-subwoofer.
And when looking into a projector, pay close attention to fan noise, some are pretty loud and annoying at low level play-back.
as always email me if you wish....best regards Chad

>>the center works the hardest<<

Gee -- where have I heard that before?

When I had my system together and I was listening in two channel, people
were always walking up to the center channel and rear channels, trying to see
if music was coming from them. They'd be surprised to find that the front
left and right channels were imaging in the center and throwing ambient
information outside the speakers and in the room -- none of the other
speakers were engaged.

Now, when I watch movies in two channel, people are always asking me where
the center channel is and they're surpised to find that the two channels are
imaging in the center. IMO, that's way better than using a center channel.

Some processors will let you select 4.1 -- with no center channel.

This would let you use your front left and right channels to image in the
center, let you use your highest quality speakers do the majority of the work
instead of a center channel.

Further, the lack of progressive scan isn't that big of a deal.

Progressive scan old technology -- soon to go the way of the dinasaur.

You want a DVD player with DVI or HDMI. Or, you can probably have your
DVD player modded with SDI. This lets you keep the video signal in digital
saving you a digital to analogue conversion.

>>-What speakers would I need to add / if any?(Sub-center- Rears)<<

I would definitely recommend a sub-woofer for movies. If you're going to use
the sub-woofer only for movies, you can get a home theater type sub that will
rattle and thump for you and it shouldn't cost a bundle. If you want a sub-
woofer for music, one that will blend with your Caravelles, you'll want to
spend more and get one that is musical. If you go with 4.1 as I suggest,
you'll also need two rear channels. These will not be doing all that much and
home theater is not as demanding of quality gear as music, so you could get
by with inexpensive rear channels. Try to demo them in home to make sure
they blend with your front left and right channels.

>>-How would I connect the AV to my Jadis integrated??<<

One way would be to connect your Jadis to a two channel pass through in
your home theater processor.

>>-My Theta DVD does not have Proscan - is that an issue?<<

You'll probably want to either add SDI to your Theta or update your DVD
player to one that employs DVI/HDMI. If you mod your Theta with SDI, you'll
be able to use an external scaler, which will give you high quality video and
you can run other things like cable TV through the scaler, too.
