it all depends on how well PS is built in the optimus, and how hard you plan on driving the speakers. at moderate volumes you will probably be ok, but i'd start to think about a different amp. not to many AVR's can effectively drive a 4ohm load given the amount of current required...you should start to look at seperate pre/pro and dedicated amps if you plan on using low impedance speakers.

He actually had installed systems for his last job and that experience was really helpful. I ended up purchasing Fronts - ref 1.5 (4 ohm) sub - ufw-10 plus 800 watt 10" definitive tech. sur - elt dipole(6 ohm) center - elt(6 ohm) I currently have a optimus professional series receiver that does not recommend using speakers under 6 ohms. I just spent a good amount of money on speakers and don't would like to hold off on a receiver for a little bit. As it's been good to me and I really know how to use it well. From 20 - 20,000 Hz, it's 100 watts/5 channels with less than .09% distortion. Would you highly recommend an upgrade with a receiver ASAP and if so which one should I look into from a power standpoint. I'm not worried about HDMI connections or XM satelite and would like something with low heat(4 ohms). Not sure about digital amps yet and I saw the Kenwood on your site? Are there receivers meant for 4 ohms? I want to fill this large room the best I can and get the potential out of these speaker. |
