Dynamic compression in speakers themselves?

The primary audio characteristics I want to achieve in my system is an open, uncompressed, unstrained, and highly dynamic presentation.  What I don't know much about is how much speakers can or do contribute to loss of dynamics and impact.  I have a very powerful amp, but it seems that when I increase the volume, yes, the speakers get louder, but perhaps not commensurate with the increase in the volume control.  I do think I understand that this type of presentation is more easily achieved with larger scale speakers, but even with my large speakers, I feel something is wanting. 

I guess my question is, what factors contribute to any compression occurring in the speakers themselves?  Also, can the age of a speaker cause a loss of dynamics?  Mine are ~20 years old.  I'm thinking to get new speakers in the foreseeable future, so I'd like to understand more about this.  This question is in regard to traditional dynamic speakers.

I'll put my 2 cents in. Get an amp that has super high current. Ignores the varience in impedance. Has mega wattage. Then if you can't afford the amp go with horn loaded speakers. Transients are what you are looking for. Super start up and stop of the cone. Only a fine amp will do this. Mega power and damping factor. My amp is stable down to a short circuit. Mega current and 350 watts. My speakers are ruler flat BUT ineffecient. Impeadance varies as low as 2 ohms.  89 db at 1 watt. If you really want the total control get as much power as you can afford. The peaks can be 1000 watts and have to rise quick and no stress on current.

I am using an Anthem P5 Statement. It is 5 channel but my preamp can do 2 channel as well. Stable down to a short circuit and beefy.

Good luck in your search. Get more power!!!!!!!!!!!!

Enter your text ...Yes you have the amplification covered quite well.

 Just get busy auditioning different brand speakers and that's it. Yes 20 yrs does make a difference. Especially if driven hard. I did a lot of research a while back and bumped int a company that makes a machine to measure cone breakup using laser dopplar. I also bumped into a company called Accuton. They make the kind of quality I think you are looking for. I didn't look any further because the speakers are out of my league. Your amp has the power, now you have to get a no compromise speaker that can handle the signal. Get the checkbook ready.Can't wait to see what you end up with.
