I recently got into fixing speaker stuff....not by choice, but because my meidong soundbar going kaput(should be me-a-ding-dong-for-buying). Here is a link. i DO NOT RECOMMEND THIS PRODUCT AT ALL: dingdong soundbar
Anyways, we took it apart to salvage the speakers. I then saw that the problem was the audio control board gone bad. It used a remote and the switch wasn't switching so i could never change modes.
Instead of stopping there, i found an audio control board on ebay from china optical audio board
that had the necessary optical attachment for my TV. When it arrived it worked good, but didn't amplify the signal and i didn't have a mixer or amp, so i got this amp unit from a frined called crown 135Ma
crown 135ma amplifier
I am using my 'found in my neighbours garbage many years ago' B&W DM110i Speakers DM110i speakers
and also these little meidoing speakers(10W X4) and it all sounds wonderful around the room. There are several inputs so as long as a projector has headphone jacks or other output, i can hook up.
i like using bluetooth as well to hook up. I am always trying new things...

Hi Matt,
Yes I also like the convenience of a Bluetooth wireless connection to the projector and, as Steve Klare recently pointed out, it eliminates any possibility of ground loop hum in the system. Only problem is latency, namely some loss of sync, in my system its about 1/4 second.

Yes, and for another thing;
-under the china cabinet,
-behind the fireplace,
-around the corner,
-behind the couch,
-beneath the endertainment center,
You will find about 30 feet of shielded audio cable between my projectors and my Amp. It is getting stepped on, mashed by furniture legs, abused by cats and run over by model trains (only at Christmas time...).
If I went wireless this would go away!

All I ask is a wide screen and a projector to light her by...

This is a very good topic! It may sound silly, but when I "organized" my sound system specifically for projecting films, i went very old school.
The reason for this is that, as we all know, as a general rule, films are a "low tech" audio (unless were talking 35MM digital audio, of course), and so, I assumed ...
... old school audio demands old school tech!
Therefore, I have a early 1980's Radio shack/Realistic Dolby sound processor. This is the very old 1970's style surround and not the later 5.1 or even better audio that came later.
The nice thing about this is the Dolby settings also allow for a "simulated" stereo form mono as well and actually makes that mno magnetic soundtrack sound pretty good and for the stereo super 8 sound films that I have (like my STAR WARS scopes), the surround is almost passable.
Oh, and that goes along with a very old school equalizer with lots of fun lil ole "levers" and a 8 big old speakers, 2 in each corner!
