What mountable bookshelf speakers are best for me?

[PAT.P]

but for the LFE it has two ports.. a red and a white.. and theres only one black on the back of the reciever..

Thats funny I own a JBL PB8 and beside the red and white there another connection for LFE its on the right side .If there none get a "Y" adapter .Pat.P
