cablebandit Posted November 21, 2010 Share Posted November 21, 2010 I have a set of chorus I speakers as the mains in my HT setup running on my onkyo nr-tx3007. it is 140wpc. I had read that these speakers love power even though they can play loudly with very little. I decided to read the manual and bridge the power to the chorus Is. the manual said that bridging gives nearly double the power so I figured maybe it is now outputting 200wpc to the chorus speakers. What i immediately noticed is that they sounded less distorted when played at a loud volume level. i also noticed a lot more difference between the loudest and softest parts of music. I think thats called dynmics but not sure. either way it was worth the few minutes to do it and I now have a clearer more robust sound.

moray james Posted November 21, 2010 Share Posted November 21, 2010 While you are in experimental mode why don't you try something else? With a little more speaker wire you might want to try a biamp set up rather than bridging. You shoud do what is called a vertical biamp set up . I assume you have two stereo amps so one amp per speaker right channel bass left channel mid/top and repeat on the second speaker with the second stereo amp. This should sound better than your bridged configuration. More separation and less bandwidth per amplifier. Have fun.Regards Moray James.

cablebandit Posted November 21, 2010 Author Share Posted November 21, 2010 I do not have but the one receiver..onkyo tx nr3007. I didnt think it would be worth it to passively biamp the speakers. Quote Link to comment Share on other sites More sharing options...
moray james Posted November 21, 2010 Share Posted November 21, 2010 I did not look up any info on your amp so I assume that it is a HT amp with multiple channels available. Must have at least four channels if you were able to bridge and still run two channel stereo. So you still have the ability to vertically biamp. Two channels right two channels left. This arrangement should sound better than simply bridging for more the power. No reason not to give it a try is there unless I am missing something? Best regards Moray James.

wuzzzer Posted November 23, 2010 Share Posted November 23, 2010 That waas not necessary or nice and five way binding posts are cheap. The bi-amplification method you described is very frequently called "Fool's Bi-amping". His comment was not directed as a personal attack towards you.

moray james Posted November 23, 2010 Share Posted November 23, 2010 Wuzzer: Thank you for letting me know this I had no idea. Can you explain how the term came about? My experience with biamping has been that going vertical makes less demands upon the amp running the low frequency drivers as opposed to a horizontal. I have also found that not all amps sound better when bridged. My appologies to Dennis. regards Moray James. Quote Link to comment Share on other sites More sharing options...
cablebandit Posted November 27, 2010 Author Share Posted November 27, 2010 Well I bought an Adcom GFA 555 amp locally on craigslist. it is 200wpc @ 8 ohms.Results....the onkyo sounds better when in bridged mode than the Adcom. I was shocked. The adcom weighs about 35lbs and the Onkyo 50....I dont know what that means about power/quality but I was surprised at the results. The Onkyo sounds "wider".....like the speakers are further apart. The adcom sounds like mono if you will. The Onkyo is a tx nr3007...claims 140wpc@ 8 ohms in non bridged mode and over 200 bridged. Now i gotta sell the Adcom that I just bought wednesday Quote Link to comment Share on other sites More sharing options...
moray james Posted November 27, 2010 Share Posted November 27, 2010 Give the Adcom as many constant on hours as you can (three days should get you going) and listn again and don't hesitate to play with the position of your speakers with the new amp. That way you will have given the Adcoma fair shake. Regards Moray James. Quote Link to comment Share on other sites More sharing options...

While the Adcom you have is a quality amp, Klipsch and Adcom may not be the best marriage. With that said, try to find an amp that is a little more on the neutral or warmish side(NAD, B&K, Marantz, etc.) Where is your location? If you are in the Atlanta area, maybe check out this amp. http://atlanta.craigslist.org/wat/ele/2047594912.html Bill Quote Link to comment Share on other sites More sharing options...
cablebandit Posted November 29, 2010 Author Share Posted November 29, 2010 thanks for the recommendations guys. The problem wasnt brightness or harshness......it just didnt sound as full and dynamic. Maybe Ill try it again today but the sound difference before was immediate. Quote Link to comment Share on other sites More sharing options...
