I think he wants to build a speaker enclosure.

Maybe, but it looks like it might be an ad as well (spamlink)

idk why u can't understand my question, i'm asking if it's better to make that hole on the back or the front of the speaker. And of course i'm building the speakers.. you don't need to buy everything other people buy, you can do it yourself if you know a bit of it.. so which is better?

The question was obtuse at best.......

So you want to know about bass reflex designs including front or rear ports, based on your less than clear answer immediately above.

To be honest, it is best that you actually design your speakers as folded horns, as you will achieve around 35% electrical power to acoustic power conversion whereas bass-reflex designs generally only achieve 2% at best.......

Providing guidance on this is beyond the scope of a short answer, as there are many different variables to consider, not the least of which is your room tuning as it stands, if you intend to alter the room with treatment and what is the lowest frequency that you will be trying to reproduce.

You also need to take into consideration the acoustic stiffness and colouration of the materials you will build the enclosure out of.

If you do it, do it good

Build yourself something modeled after the klipsch horn!

Agreed.... I built my first and second set of speakers with 12" woofers and piezo tweeters and a piezo horn for the mids in one design.

these days I would spend a lot more time and build the folded horn designs using 3/4" ply or even solid boards if I can afford it.....
