nick46:I know you should not put speakers in corners, but my question is if it is a front ported bass speaker will it make a big differance as the sound is all coming out the front into the room.
Any time you place a speaker close to a wall or in a corner, the bass will be boosted, whether the speaker has ports or not.
Obviously, the bass will be boosted even more on rear ported speakers - but front ported speakers will still suffer an artificial bass boost, even if you block the ports.
It's a natural side effect of placing speakers close to walls / corners.
