The wise men on this forum are sooooo right... for Audiophile quality...be very careful
A few years ago I bought this (wow now almost a decade ago):
Tannoy Kingdom 18 - Yes the 18 is for Damn powerful 18" Driver, 15" Mid&Bass 3" Tweeter and 1" Supertweeter
Took me three years to make it sing.... the best room was a guy called Brian with an 11x14m room.... I managed in 6x8m room, but then at 14Hz NOTHING doesnt rattle, overpower the room... flip man CD's skip
Does 300W work - No, just sometimes... that is in 8 Ohm
I can only say - Careful for what you wish for :->
Then I heard a Mark Levinson Rosebud and it blew me away.....
