What is the ideal infinite baffle characteristic also it would be helpful if i knew the difference in terms of efficiency compared to sealed and ported systems.
I've found the following characterizes a good infinite baffle:
*strong such that vibrations and resonance are minimized
*separates the front wave from the rear wave very well; no leaks
*arranges the speakers dual opposed; force cancelling design
Efficiency will depend on the frequency in question and how much cancellation exists around the baffle. Typically, IB is more efficient than sealed but less efficient than a ported box.

Hi,
In theory an infinite baffle driver has no limitations at all.
Ask a more sensible question for a more sensible answer.

Perhaps as good an answer as any would be another question - what is your intended application?
As with numerous other technically excellent topologies, the "where" and "how" the system will be used must be included in the design calculus.

😉 I was going to answer: It might be better if you ask a question which has an answer 😉 I waited and others have the same impression 😉
I am sorry if it did not make sense i just wanted to compare a driver in closed box case with infinite baffle. Like what is the limit, and how much effeciency we are losing when mounting in closed box.
It all depends on how "infinite" you mean. Just for clarity, some people & vendors, call a closed box infinite baffle.
A closed box will MORE effecient in the bass, & reflexed about 3db MORE than reflexed !
If you have any way to EQ the signal then it is much better with a much stronger low Q driver. You need a lot of voltage-swing but not a lot of current if you use high efficiency pro drivers. B&C 15TBX100 is a good OB driver for bass duty. You can get great efficiency from OBs. It is as usual a large radiating surface, low moving mass and lots of BL (motor strength) that will create efficiency.
Cheers,
Johannes
