Hi Audio Experts
I am in Bangalore for some official work and will be going back to Pune tommorow...
Out of the blue, I went to Sebastian and Sons and met Zac there for some decent speakers for my dicor...
He suggested to go for, compos in the front(6k) and coax(3.2K) in the back..
Now please suggest the following
I am looking for good sound.....i mean the clarity like when you you put of headphones

(or nearly like that in the budget of 15k)
Que1 :::: Shall I go for the Blaupunk offered by dealer ( i heard that its quality is comparable to alpine) If so then what least model shall i query for from the dealer to support this configuration of speakers?
Ques2:::: What is the actual size of the speaker in the doors (5 1/4 or 6 inches) dealer said 51/4 and some mentioned in the thread 6 so i am confused
Ques3::: Is it ok to go for Blaupunk coax in the rear and boston compo in the front.
Ques4:::What amp are required if any ?
No sub as for now...
Thanks
