No, they are available through import only. But there might be some shops importing them as Pioneers clearanced its 51 to make way for 52. I read somewhere here that it is 18K per pair in Mumbai.
I have a Pioneer Receiver and I ordered Jamo S426.
Pioneer FS was very good. But I had to go with Jamo.
It looks much better and the package is a good value.
It is hard to compare, but if you like loud mid range you would love Pioneer.
Don't go for it. Sound will not be good for home theater. In same budget you can get Yamaha or pioneer entry level receiver plus taga harmony 5.0 package. You can add subwoofer later when budget permits
