A question about front-ported speakers

Why I like bottom porting, designer knows distance to floor and can design for it, front and rear port its up to user to hopefully find best placement.

I have my speakers 6" from the rear wall and they work great!
The ports are front-firing.

But- the front of the speaker is about 2 1/2 feet from the rear wall, so maybe they don't count?

Thanks for all the detailed responses.I know every situation is different and mine is definitely not ideal.I'm trying to choose between Paradigm Studio 40's and 60's.The 40's are 13 inches deep, and at 10 inches off the back wall they are 7' to the front from me.Eventually I plan to move to a bigger room, say in 2 years or so, so I've been toying with the idea of the 60's.The 60's are 17" deep, so I would have to put them about 5 inches from the wall in order to keep them, almost literally, out of my face.I have some research to do, and thanks again for the info.

Sprink -

sounds as if you know this but in the hopes of being helpful...

sounds as though you are setting up a near-field monitoring situation. the generally recommended math is an equilateral triangle - meaning that the speakers are as far apart as they are from you

finally - don't torment yourself with what might happen some day in the future. get the right speakers for you today. 2 years is a long time and it is more then likely that your tastes will change. It is also entirely possible that the smaller speakers will work well in the bigger room.
