they are amazing speakers .... the sound is great, don't get me wrong ... but to me they seem little bright. The male voice is not the problem ... it is just making obvious that they are little towar bright range. The bass in male voices are mostly missing. My crossover is set on 100HZ on my Onkyo. The EQ is fine ...
May be I should also rise the spearkes on something because I am very close to them, because the room is small and being close to them, the high freq tend to be stronger .... do not know
I have no other way to put this than to just say it how it is..... You need to reconsider your speaker choice/wants & why you want towers. I'm not saying this to beat you up, I'm trying to save you time & money. If it were as easy as people on the Internet say or like to pretend it is, I wouldn't have a job doing this 7 days a week. You are overbuying for your room by going with towers.
Also, I must apologize. I read your OP, but missed on the room size you have. I would've typed something differently instead of my original post.
Even ifmyou choose to ignore my advice below, you positively, absolutely need to set your speakers to "large" in the receiver. 100hz crossover without a sub is why you aren't getting bass or mids, so change that as well if the receiver does not do so automatically. You also need to tell the receiver NO sub in the setup menu.
My absolute best recommendation in that small of a room: Why you would not consider a high quality monitor on stands? In no way are you using a tower to it's potential in a room that size. In your room this type of layout will give you the absolute best sound for your $. Even without a sub, a high quality monitor like the Phase Technology PC 1.5 will out perform most towers in your room, listening volume, & budget.
We have used them in several systems and they are stunners. Here is a recent review from Home Theater Magazine:
http://www.hometheater.com/compactspeakers/phase_technology_pc-15_speaker_system/index3.html There are matching stands available & dealers who do good volume through Phase Tech can get you a great price that should be in your budget.
This would be a strong option to consider & should give you fantastic results given your variables. Good luck!
