U havnt cleard my questions tho ..
Well that's unfortunate. Let's start over

.
i want to know whether the B&W MT-50 is more than enough for a proper home theater room with acoustics of the size 12.5 by 11ish feet ?
The MT50 specifically will be enough, but then again, any well designed satellite+sub system will be enough.
since it is the small room i want to knw the difference .. whether its much or not much.. cus i need to knw if its worth payin all the way up for the MT 60 when the MT 50 is more than enough ..
The MT60 is not worth the $1000 more (the main difference is the subwoofer). I doubt you'll be able to tell the MT50 and MT60 apart in use.
oh and also i want to know sry this is out of topic question but .. i want to knw if the Kef 3005se is a better pick than the mt 50
No, they're more or less the same. If anything, the Kef is more expensive than the MT50 and I doubt you'll be able to tell them apart in use.
why I want to go for the B&W or paragdim or kef is cus of quality with sound quality and ofcourse elite name it has got ..
These brands (including Kef) definitely produce very good products and are famous. Some of their products definitely fall into the "elite" category. That said, they all produce products that are not worth the money you pay for them. Further, their products have huge markups. So, you are paying for the brand name/ "elite" image and up to 50% profit for everyone in the chain. On the other hand, products from non-elite brands have to perform better than their price point, to get positive reviews.
