With a room like that it's no wonder your speakers sound bright and harsh. Put some rugs on the floor. Hang some oriental rugs or tapestries on the walls. Almost any speaker would sound bright and harsh in a room furnished like that.

.....almost all of these rugs are 63" X 91", are machine loomed with tightly stitched borders, and very decent quality with free shipping....I personally have 5 with a couple of them already hung on the walls....(the rugs look so good you won't even notice the gal in the red top and wheat colored jeans)....(as if).....

Why would a speaker sound lifeless with a flat frequency response? My interpretation of "flat" is: If a sine wave is output at frequncy "F" at a given amplitude, at "F+x"(x=any real number) it's output is the same amplitude.. In other words, sine wave's at different frequencies, with the same amplitude should be equal in relation to each other. When actual sound is played, the sound will not be "flat", but exactly as the engineer intended it to be, assuming he/she is using equipment with a flat response. That is what I understand to be "flat".

I also noticed that you mention speakers with +/- 1.7 dB response, which I think is very close to 0. Perhaps as close to 0 as they can get throughout the entire frequency range that they are capable of playing in.

.....like I said, Nuglets, I stated what the guy who made my speakers said....he's been doing what he does for about 40 years in his shop, and carries the title of Mr. Crossover in the audio industry....he spends hours unto days tuning every speaker he makes....I couldn't care less about going any deeper into speaker tuning, I'd rather spend my time listening to his speakers....I can fix a lot of things wrong with your locomotive or boxcars you might have in your backyard, but designing speakers hain't my forte', nor do I want it to be.....

They don't strive to be flat?

Of course they do. One only has to read the design goals arrived at the National Research Center in Canada over many years of research.
But, don't forget, these frequency responses are only arrived in an anechoic chamber, not in any room that introduces its own acoustic issues.

.....no, they don't, or that's what they would be "close to" at a much higher cost.....virtually all of the commercial speaker manufacturers arrive at the "industry standard" of +/- 3db and stop there....you need to quit reading so much and move up from an entry-level receiver.....
