Listen to UNSOUND. Get your room dimensions correct. I've owned SCIVs and SCVs. SCVIs do require a large room and I do think placing them on the long wall is best. I would look into narrowing one dimension of your room. Something like 20x17x 9. Dunlavys can be placed quite near the rear wall, so you might have enough room. If this doesn't work- consider a pair of SCvs.
