    Do any of you know for sure if I can use my non-shielded front speakers (directly on each side) with a Samsung DLP or a LCD??

    Please no guessing, I'm ready to buy if the answer is yes.

    Thanks
    Darryl

    Since the large picture is being projected from a small picture element (either dlp chip + color wheel or LCD panels) deep inside the set you should have no problems what so ever. Even standard CRT RPTVs are nearly imune to non-sheilded speaker problems. LCD/DLP sets should be even more imune to such problems.

    Hope this helps [​IMG]

    Thanks Stephen, I have a pair of JBL LX 500's that I love to death and I want to keep using them as my mains.

    I have been using them for several years with no problems, because they are set 3 feet off to the side of my direct view.

    Thanks again,
    Darryl

    You will have no problems.

    The problem only arises because CRTs function by magnetic fields to move the beam around inside the tube. No CRT, no magnetic fields happening really, except for the electronics which won't be effected by such small changes.

    As for the statements that CRT-based RPTVs are nearly immune, that's not really the case, it's merely the fact that the tubes are in the front bottom of the set in most cases, therefore there is usually a good distance between the tubes and the boundary of the set. Problems usually arise with subwoofers, or other unshielded speakers that might be put down low in front of an RPTV. To the sides by the screen of an RPTV is usually quite a distance away.

    Direct view sets ARE a big tube, so the boundary of the set is pretty much the edges of the tube, so putting a speaker close to that will net you a much more visible effect. Furthermore, you will see this easier as colorations on direct views, as with 3-gun CRT projection devices, you may miss the effect completely, as it will likely just cause misconvergence, which many people never notice anyway.

    The location of the CRTs was the basis for my "nearly imune" comment.
