Piano and Trumpet can sound bright

In the vast majority of jazz clubs, the performers are miked. This is actually what creates most of the brightness, the sound systems are just too damn loud. There may be some clubs in NYC still that don't mike, but there sure aren't many anywhere else. That said, even with a performer that strives for a dark trumpet sound, which for instance most orchestral players do, it is still a bright instrument compared to most others. And most jazz trumpet players are not necessarily striving for a dark sound - a lead player in a dance band quite the opposite, for instance.

Check out the frequency response graph of the Celestion SL700 in this Stereophile review:

While there is a big dip in the frequncies between 10k and 20k the spike beyond 20k would have to have an effect on the sound of the speaker,IMHO. That spike is found with many metal tweeters.

Charles1dad, Ah, I think we have a better understanding now. I was not suggesting that trumpets always sound bright, just that they can have their moments of brightness, and perhaps more so than some other instruments.

Time to upgrade.

Yeah, it's the interconnects. Go to PBJ and dump the Silverstreak and KCAG.
