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.

If you’re looking for an excuse to spend money, you have been given many. But my immediate instinct without a second’s hesitation is, “Oh! Well, just toe them out!”

If you are receiving too much energy from the mids and the energy increases with frequency, toeing them out is a perfect fit.

Directionality increases with frequency, too. So toeing out just a little bit has the most pronounced effect on the highest frequencies, less on mid, and it goes drops off rapidly from there.

Toeing out sounds fine. Not to harp on this, but simple attenuation is the right solution. Looking at the crossover, a resistor change looks extremely easy to do cause it appears accessible from the base and detachable with screws.

The tweeter section is at the top and you’d want to try higher values for the series resistor (before the coil!) to the tweeter’s positive input. Mills MRA is very cheap. You could also even just use alligator clips to parallel on incremental values to the existing resistor to determine the best overall padding. http://www.sengpielaudio.com/calculator-Lpad.htm

You might talk to Mark Kreckler at Soundings in Greenwood Village, CO.  They specialize in Master Setting speakers.  I would start there first.  They also specialize in REL subwoofers.  REL uses a different technology to create a sound stage in order to clear up high and mid frequencies.  They are not designed to produce that heart throbbing bass, but to provide greater bass extension to provide greater relaxation when listening.

Your clear ovals May indeed be part of the problem. They are entry level Analysis Plus. Try their Oval 9’s. They remover some glare and add more robust. They should tone down your TAD’s peakyness. An inexpensive way to resolve your issue. Next, I’d by a Lyngdorf Room Correction Pre-amp and be able to create a sound curve that you like. Lastly, yes, your room is likely involved as well. Dan D’Agostino designed he-man amps before he got tossed from Krell. I haven’t heard your amp or system for that matter. You ought to consult with your dealer as he or she ought to want you Happ y with the tens of thousands you graciously spent with them.
