Bobcat979 Posted August 12, 2003 Share Posted August 12, 2003 I'm about to purchase some RF-15s as fronts. My concern is, the RF-15s are rated at 100 watts continuous and my reciever is rated at 110 watts per channel. The reciever is a Sony STR-DE935, which I'm also hoping to replace very soon. I just wanted to know if the Sony will be okay for the RF-15s, until I get my new reciever. Thanks Quote Link to comment Share on other sites More sharing options...
formica Posted August 13, 2003 Share Posted August 13, 2003 I don't see why not? Are you concerned about Sony's receiver quality? Clipping your amp? Or is it the 10W difference has got you concerned? Measurement procedures from one manufacturer to the next will easily vary more than 10%... so 110W is pretty much the same thing as 100W (i'm assuming that both the speakers and reciever are rated at the same ohms). Also note that the speaker rating is given as RMS which is Root Mean Square (ie: avg continuous power) and it will take peaks of significantly more power while the receiver usually has very little head room (small peaks versus it's rating). Your biggest risk is actually the opposite; pushing the amplifier section to it's limit, clipping, and feeding the speakers with "distortion"... the cause of most blown drivers. Hope it helps your question... Rob Quote Link to comment Share on other sites More sharing options...
Bobcat979 Posted August 13, 2003 Author Share Posted August 13, 2003 Thanks for the info. Of course, I just changed my mind and decided to go with RF-25s instead of RF-15s. So I know for sure that I won't have a problem now. Quote Link to comment Share on other sites More sharing options...
ricktate Posted August 13, 2003 Share Posted August 13, 2003 Speaker rating has nothing to do with the reciever power.....not the way your thinking anyway....might be a problem if you had 200 watt amp and 30 watt max. speakers. other wise get the ones you wanted ,,,rick Quote Link to comment Share on other sites More sharing options...
Inlite329 Posted August 14, 2003 Share Posted August 14, 2003 In the pro side of audio we always put about 10%-30% more power to the box then the rms rating. It always made it sound better and more responsive. Of course it makes it more costly but worth it to me. I plan on bi-amping my RF3's as soon as possible Quote Link to comment Share on other sites More sharing options...
PhilMays Posted August 15, 2003 Share Posted August 15, 2003 You were fine, unless the distortion on that reciever was too much. Also I doubt that the reciever actually pushes that much power while all channels are driven. I think you made a wise choice by upgrading your speakers anyway.

chief7771 Posted September 8, 2003 Share Posted September 8, 2003 bob, you won't be disappointed in getting the rf25 vs the rf15. I too went into my local dealer with plans to get the 15s, but decided on the 25s after I heard them. rob Quote Link to comment Share on other sites More sharing options...
Iceman Posted September 8, 2003 Share Posted September 8, 2003 Definately go with the larger speakers. Not so much for the power rating, but the increased efficiency will sound much louder Quote Link to comment Share on other sites More sharing options...
