@Sachin... I was also looking for MA BX2 center. Looks like I found a solution for this. I called TheAudioPeople. They have Monitor Audio speakers. It seems that they are willing to ship to anywhere in India. :yahoo:
Note: I've asked for a quote as well. I'll update accordingly.
Update
--------------
I've received a quotation from them yesterday:
BX Center - 20000/- (plus shipping)
BX1 (pair) - 30000/- (plus shipping)
