you can check out the center channel I made using a horn on my webpage. Its in the Speakers section. I was not able to find any 6" drivers that had higher than 91db efficiency that were shielded. maybe you could find some alnico magnet 6" high efficiency. I have the horn padded down quite a bit since I can only get 94db out of the two woofers. then, you will have to boost the db to the center in the receiver. but hay, thats why your new receiver is going to have all those nifty option!

You can buy a Klipsch RC-7 which is horn loaded and 98db or better. it will set you back around 500 usd.

you have to buy factory shielded speakers or use speakers with Alnico magnets. forget about trying to shild anything yourself.

The one I have works great but it was a project. check it out
