This place has people who put up reviews (their own opinion I suppose) if anyone has done that in one section, or you might see a thread in the Low Theory End (different sections to look around in) for opinions on speakers.
It looks as if you are mixing perhaps 8" speakers with a 5" and a 4", but then I am not sure.
http://www.gearslutz.com/board/ The 5" JBLs new ones are getting good reviews. People want to know about the Equators Speakers 5" or 8".
JBL also makes the Control 2PS, but those are mainly like computer speakers and I think 4", but then.........................
I am not sure and liable to mix things up.

Listening is the best thing to do. And checking around on websites.
I have not heard them all, but KRK are mentioned as bassy.
