perfectly said
for cinema only dont invest on fs..
bs will do..
invest on costly centre and costly sub...
avant centre is fantastic...another fanastic budget centre is polk csi A6 ...
one thing keep in mind you have big room..so powerful avr is needed..
any less than denon 2113 or other brand cousins..wont be good imho
imho...buy avr,centre,sub now...otherwise you will be forced to buy compromoised products than your room and need..
get bs/fs and rear dipoles later
trust me from proper source(mandatory)..a solid centre and a solid sub is quite enough for a cinema only purpose
