Best Design for Speaker system

YourTechMate

There are many possible speaker box designs available like Bass Reflex System, Infinite Baffle, Passive Radiator, Band Pass and Dipole speakers system.

I am aiming to obtain maximum Bass output out of the box structure. Any thoughts which of the above structures would be the most suited for my requirement and why ?

there are three suggestions

bandpass design,
normal but complete airpack
L-shaped...

now i explain them ...
band pass design is the one, in which , ur subwoofer usually, are inside a box, and is covered fully ,such that ,it cannot be seen. also , it is completely coved, so no air can come to it....

normal but complete airpack...
this type of system have usually woofer, though we can see the woofer face,, but the back is fully covered.. so no one can see the back,,, also all the design is complete air tight. as above.....the Harman-karden HK-395 model is an ideal example... i also have that one.. u can search on google. and watch out the deisgn
....
L-shaped.....
this type of box have a woofer,, of right angle type., the woofer is on hypotenous,... and the opening hole to escape the air , or echo is on the top of it.....

Ok, So which one of these would be best suited to get maximum Bass Effect. I believe 'bandpass design' and 'Bass Reflex' design are the two major NOMINEE for the maximum bass effect. Any thought on this ??
