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.

best way to tame a bright speaker, is with a true analog source, preferably tape.   1/4" tape at 3.75 IPS will tame any bright speaker, or if you prefer 7.5 IPS.
You say don’t say this, but it has to be said:  Fix the problem where the problem lies...if you think your Speakers are bright, why do you want to put bandaids throughout the system?   You’ll sacrifice everything you do from that point on because it’s all based on the fact you don’t like your Speakers.  As soon as you say that you still like your Speakers and throw the word but/except, then don’t say there’s a problem with the Speakers.  What you’re contemplating doing would be like buying a car based on which tires you want to have...
The TAD Evolution Ones played everything from audiophile recordings to low-bit-rate Internet radio with aplomb and authority. Teamed up with neutral electronics and a room not excessively damped, they should provide the buyer with richly musical enjoyment for years to come. It's easy for me to say that the Evolution One is a marvelous speaker—I found no fault with it.

Thanks everyone for all the good advice.  I have tamed the brightness and agree with  Kal Rubinson that the TAD Evolution One is a marvelous speaker.  I am definitely enjoying it.
