What is the best way to tame a slightly bright speaker?


I know the answer is get a speaker that isn't bright,  but I've got a pair of TAD Evolution Ones that I like quite a bit except that the magnesium midrange and beryllium tweeter are just a little bright for me.  I'm driving them with a D'Agostino Classic Stereo, which I needed to drive my old speakers but I don't need all that muscle for the TADs (89db sensitivity, 4 ohm impedance {doesn't drop below 4 ohms}) recommended power 50 to 250 watts. 

I'd like to get  an amp that does voices especially well.  I know somebody posted recently that a subwoofer solved his brightness problem and I may look into that at some point.  Any and all suggestions are welcome.

I think that either the speakers or the amplifiers may be bright sounding, however I wouldn't start by replacing them. An overly simple solution might be to fit a small piece of foam over the tweeter, one where you could add a piece of cloth over it to increase it's ability to reduce the amplification. 

Not pretty but not expensive and not permanent and adjustable to your liking. 
I feel the best bet to tame a slight bright issue would be to try smoother sounding cables. There are so many to choose from. You can try interconnects or speaker cables. For me, I find anti cables sound smoother and not as bright as many cables out there. 
Buy a nobsound volume control . I guarantee your speakers will not be bright once installed .
