Tucahay Posted April 11, 2021 Share Posted April 11, 2021 Hello all, new member. I just acquired a pair of Chorus ll which were included with a Kenwood rack system. Having never owned vintage Klipsch, I have been reading alot about these speakers. I have read that the Chorus ll sound best with around 100 wpc. I'm wondering how my Onkyo A-7070 will drive these at 70 wpc, any opinions? Quote Link to comment Share on other sites More sharing options...

How do they sound with the Kenwoods? My buddy once had a vintage Kenwood integrated amp(45w/ch) driving his Chorus 1s and the combo was wonderful. 5 hours ago, Tucahay said: I have read that the Chorus ll sound best with around 100 wpc. I'm wondering how my Onkyo A-7070 will drive these at 70 wpc, any opinions? Probably pretty darn well. I never owned the A7070 but did have a 90's A-9711(80w/ch) integrated amp driving my Heresy 1s, Heresy 2s, and Quartets and all combos sounded great.

Buddy Shagmore Posted April 11, 2021 Share Posted April 11, 2021 Hook 'em up! I drove my Chorus IIs with my 45wpc Marantz 2245 for several years. About a year ago I upgraded to a new Yamaha AS2200 (90 wpc) integrated. Let us know how you like 'em! Quote Link to comment Share on other sites More sharing options...

I'm wondering how my Onkyo A-7070 will drive these at 70 wpc, any opinions? --these speakers are rated at 100 watts per channel ---best is 200 watts for even more headroom - you'll be ok with 70 watts to play the speakers , but dont play them too loud , for a longer period of time , as the sound will be distorted -but , at low volumes should be ok - Quote Link to comment Share on other sites More sharing options...
Chorus1 Fan Posted April 11, 2021 Share Posted April 11, 2021 I think those who say that must mean 100w via a modern a/v reciever. I say try your Onkyo 1st, then decide. I have a 70w Luxman (R-115) pushing my Chorus 1's & with the volume at about "10 o'clock" things start falling off shelves & my chest feels like CPR has started ! (& 0 distortion) Quote Link to comment Share on other sites More sharing options...

Chorus II perform best with quality SS amplification and at higher volumes, you can push them pretty hard for as long as you like and not be concerned with any damage. You will likely damage your hearing before you damage these speakers. You will never even get near hitting them with 100wpc. Those who say you "need" 200wpc are clearly misinformed. Chorus I and IIs are distinctly different animals. 1 1 Quote Link to comment Share on other sites More sharing options...
Sixes Posted April 11, 2021 Share Posted April 11, 2021 (edited) I am in the middle of restoring a newly acquired pair of Chorus I speakers. My plan is to drive them with a Decware Super Zen Triode amp when I finally get mine. Currently there is a 24 week wait, and I should have it before summer. The speakers are currently apart and the cabinets are being restored by me. I have a complete Crites crossover and Ti diaphragms arriving this week. Also some oak veneer to redo the risers.

The Chorus I is not as placement dependent as the Chorus II due to it's being front ported and not having a rear passive driver. As I said previously, the Chorus II responds very well to high quality solid state amplification, and is more capable of higher volume performance than the Chorus I.

Tucahay Posted April 12, 2021 Author Share Posted April 12, 2021 Thanks for all the info, sounds like the Onkyo will do just fine. I didn't know what the differences were between the Chorus models. Very helpful. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted April 12, 2021 Share Posted April 12, 2021 If you are looking for Chorus, cannot see you disappointed in the 1s... Welcome! Quote Link to comment Share on other sites More sharing options...
iaRIVR Posted April 12, 2021 Share Posted April 12, 2021 I've heard that too, and so far I would say it does great with power. My experience is limited, but that big ol woofer can use the power to really control it and keep it tight. Maybe dampening factor is more important that watts. Mid and highs are great with anything. I've gone from 25 watt HK430 to 120 integrated, now at 150 watt NAD and 220 watt B&K. Kinda liking the NAD at the moment. Edit - revising this post as I have no idea whether that woofer has any bearing on anything, that's something I read and it made sense. Trying to get away from speculative hearsay. 1 Quote Link to comment Share on other sites More sharing options...

Klipsch Employees Trey Cannon Posted April 12, 2021 Klipsch Employees Share Posted April 12, 2021 This is a preference question or a Math question.... Math... 101db@1w/1m 2 x power = 3db 100 W ph. 1 Watt dubled, then dubled... 1,2,3,8,16,32,64,128...that is 7 times. 7 x 3 =21db output... 101 + 21 = 122db max out. to get there clean, you need at least 6db headroom. So 4 x the power. 128 x 4 = 512 Watts per channel to reach full volume with headroom at 1 meter. Your seat is ....4 meters away...for fun...-6db every time the distance is doubled. that's 2 x -6 = -12db off the level due to distance. SO, with about 500 Watts to each speaker, you can have 6db of head room and about 120db at your seat. IF you want 3db less than that, cut the power in half. 2 1 Quote Link to comment Share on other sites More sharing options...

Perhaps "capable" was a poor choice of words. I feel the 2 "sounds better" at higher volumes, to me....maybe that's a better way of putting it. And yes, the 2 mid horn makes a difference for sure. 1 Quote Link to comment Share on other sites More sharing options...

That explains why for 30 years I have always loved these with big ole amps. With all the other models I've owned the K-48 is a freaking beast! I've found that 1200 wpc works very nice. I have to thank Craig for that one. Quote Link to comment Share on other sites More sharing options...
