New Speakers To Buy

At present I have a pair of Jm Lab Cobalt 815 about 17yrs old the tweeter in one speaker has gone out. Do know if it can replace it.

Now in search of a new pair to buy...using a OCM 200 Amp and have a small listening room about 15 X 15 X 14.

Thinking of B&W 836 ..NHT Tower..Klipsch RF Line and the Hersery III. Looking for a wide and deep sound stage with a depth of detail from that speaker.

Love to hear of what else could be out there to listen to.
