why do my polk sda 1 monitors subdue male vocals?


the equipment i run them with the polks is an adcom 545mk2 amp,a 555mk2 preamp,an audio source equalizer,and a denon 1500mk2 cd player. i listen mostly to classic rock and oldies. it seems male vocals are muddied. any idea on why would be greatly appreciated. speakers were checked by a highly respected audio repair shop here in northwest indiana, he claims they are functioning properly. polk claims they have not heard of this problem with these speakers. other than this i like the sound of the polks. each cabinet contains four 6.5inch midbass drivers and two sl 1000 tweeters and a passive 12 inch bass driver.

as an example, if you are talking about klipsch heresys, or other hybrids they have a forward midrange character...they also don't have the top end and low end the polk's have. balance is king and the sda's are classics.
Racerx322,

I'd suggest you get that owners manual and ask them for the SDA trouble shooting guide. I know you had them checked out, but it sure seems as though they have a problem. Of course, it could be, as Jameswei pointed out, that the Klipsch simply mate better. Let us know the outcome.

Another thought, try taking the EQ out of the system entirely.
