Hi I have a pair of Linn keilidhs either side of a double doorway. I plan to have a scree and pj installed that comes down over the doorway so will need a centre speaker that I can lift in and out of the way as required. Any suggestions for one that is light enough to be moved but heavy enough to be good, match the Keilidhs and suchlike? Denon 3803 will be running them. Ta.
