jcmusic Posted June 30, 2021 Share Posted June 30, 2021 How much power is needed to run these speakers for the most part? What about Heresy II's and III's can the same amount of power be used? Quote Link to comment Share on other sites More sharing options...
ricktate Posted June 30, 2021 Share Posted June 30, 2021 I run mine with HK 430 reciever with 24 watts but have had a Carver 140 watt amp on them. I also have ran them with battery powered boom box when power was out and we were rock'n in the ice storm. Everyone could hear them in the neighbor hood...lol. Conclusion you can run them with almost anything. If you want vintage I would go for HK 430...630..730. Basically those have 2 separate amps in them. They sound awesome. 1 Quote Link to comment Share on other sites More sharing options...
ricktate Posted June 30, 2021 Share Posted June 30, 2021 Vintage Harman/Kardon 430 Twin Powered AM/FM Stereo Receiver 25W per Channel | eBay Looks like it just needs a deoxit cleaning you should do it twice to get the gunk out all of it. 1 Quote Link to comment Share on other sites More sharing options...
BadChile Posted June 30, 2021 Share Posted June 30, 2021 I run Heresy IIIs using a 8WPC Elekit TU-8200 in a medium sized room with two subwoofers. Gets loud enough my wife and kids tell me to turn it down from the other end of the house. 1 Quote Link to comment Share on other sites More sharing options...

I wouldn’t touch that unit with a 10 foot pole. Lots of issues. Quote Link to comment Share on other sites More sharing options...
Pondoro Posted June 30, 2021 Share Posted June 30, 2021 When my Heresy 1’s were delivered (2020) I did not have an amp yet. I connected them to my iPad via a cable. They certainly did not “fill the room” but were enjoyable up close. Current amp is theoretically 70 watts per channel but I rarely crank it.

What about Heresy II's and III's can the same amount of power be used? How loud do you wanna be? How big is the room? I've had Heresy connected to anything from a few watts to well over 100. Larger the space the more watts you'll want. Quote Link to comment Share on other sites More sharing options...
Godataloss Posted June 30, 2021 Share Posted June 30, 2021 At least one good watt. 1 Quote Link to comment Share on other sites More sharing options...
DirtyErnie Posted June 30, 2021 Share Posted June 30, 2021 ^^^ That. And then, how scared do you want to get when the cannon goes off? That'll take more. 20 watts might make you jump, 2,000 might make you soil yourself. Season-to-taste. Quote Link to comment Share on other sites More sharing options...
jcmusic Posted June 30, 2021 Author Share Posted June 30, 2021 So it's a small room so I guess anything from say 5 wpc would be good? Quote Link to comment Share on other sites More sharing options...
Dave1291 Posted June 30, 2021 Share Posted June 30, 2021 Running tubes there are some nice lil smaller amps that would work perfectly. If you're going to buy a receiver check into some of the smaller stuff that's new. You have a multitude of ways to go with those speakers and it's on you to decide. Go listen to some of the new receivers paired up w/Klipsch @ Best Buy or somewhere. Heresy's will sound nice with just about anything you throw at them. Old or new.

Steve. Posted July 1, 2021 Share Posted July 1, 2021 I was running my Heresy IIi with a pair of 40 watt Quicksilver Mid Monos and it was a great match. Plenty of power in my 15 x 17 room .... I gave my brother a pair of H2 and he was driving them with a 15 w Technics receiver . they don’t need a lot of watts but the better the amp the more you will be rewarded 1 Quote Link to comment Share on other sites More sharing options...

Beenaround Posted July 1, 2021 Share Posted July 1, 2021 I got a pair of 1’s last weekend and finally hooked them up today, I’m running 6.5 watts per channel. It’s actually plenty of power for me but I tend to listen to music a little softer nowadays. 1 Quote Link to comment Share on other sites More sharing options...

yamahaSHO Posted July 1, 2021 Share Posted July 1, 2021 I have used an Emotiva A-100 with happy results. Quote Link to comment Share on other sites More sharing options...
garyrc Posted July 1, 2021 Share Posted July 1, 2021 About 30 watts to provide THX fs of 105 dB at about 15 feet away in a large living room. If you're going to really crank it, add a subwoofer. 1 Quote Link to comment Share on other sites More sharing options...

I think he is at least honest and nothing wrong with it that a good cleaning would not fix. Best price also. Quote Link to comment Share on other sites More sharing options...
