I need to buy some HT speakers that will go in the bookshelf. I
originally wanted mini's or monitor 3's, but they are rear ported. Is
it absolutely necessary to have front ported speakers to go in a
bookshelf OR would I be ok if they were 4-6" from the back of the
bookshelf?

If I need front ported, what would be a good choice for around the
same price?

Thanks for the help.
