shawjohn42 Posted November 24, 2011 Share Posted November 24, 2011 Hello, I was planning to sell my dad's KHorns and Hereseys, but the more I find out about them, the harder it is to let them go. So I'm going to try them out. I don't know much about power requirements. Would someone please tell me how much power I need? Do I need a different amp for the Hereseys? Is there a site that will answer these kind of questions? Thanks John Quote Link to comment Share on other sites More sharing options...
Coytee Posted November 24, 2011 Share Posted November 24, 2011 I'd say a quick answer is, just about any amp will work for you. Once that baseline is established, then the question gets more nuanced. Do you want concert levels and chest pounding while standing 20 feet away and to go deaf within 3 years? Then a higher powered amp might fit your bill. Do you on the other hand, listen to jazz type stuff at background dinner levels and every now & then turn it up a bit for more toe-tapping but not "concert" levels? If so, then perhaps a "flea powered" amp would fit your bill. I've had a 1 1/2 watt/channel tube amp on my Khorns and they filled the room nicely and was probably the nicest sonic sound of all. I've had same Khorns attached to a 400 watt solid state amp and it brings out an entire different potential in them. I've had various amps as well (8 watts, 16 watts, 30 watts, 100 watts and 450 watts). All had enough power for my needs while doing reasonable listening and maybe some light toe tapping. When I was out of the room (working in another part of house) and really wanted to step into it, I had to use the larger amps. I wasn't blasting it while 'in' the room with them....well....not for long anyway [A] Quote Link to comment Share on other sites More sharing options...

Chris A Posted November 24, 2011 Share Posted November 24, 2011 Good to hear that you're going to try them out: you may decide that they're keepers (...or maybe not...it's okay either way...). Would someone please tell me how much power I need?If you're using a transistor-type amplifier, something with about 15+ watts per channel is more than sufficient. The better the quality of the amplifier (if it is a low power amp), generally the better the sound. Tube amps will typically sound much more smooth than most transistor amps, and you will find tube amps are generally much lower power - as little as 1.5 Watts/channel. These will work, too. Do I need a different amp for the Heresies?Heresies don't need any more than Khorns, but if you have a choice, I'd recommend something in the 40 W/channel capability (not that you need anywhere close to that amount of power unless playing something very, very loud and dynamic). If you find an amplifier with 40 W/channel - that's plenty.Is there a site that will answer these kind of questions?You're on the right forum. I don't know of any FAQ on amplifiers for Khorns or Heresies, but you should be able to search the forums using Google for keywords, and adding the following to restrict your search to this forum: "site:klipsch.com"Make sure that you place the Khorns tightly in corners to form a seal with the corner between the left and right side of the back of the speaker - they will not sound very good if you don't. Also note that it is a good thing to place use something on the floor if it is bare wood/tile/vinyl to soak up stray midrange energy. Also try to keep as much as possible clear between the two speakers that can reflect sound - such as large equipment racks, cabinets, or architectural details like brick masonry. Placing a little bit of fuzz material (like a thick beach blanket) on top of the speakers - letting it stick out in front of the speaker about an inch if it is rigid enough - this will also help to control ceiling bounce. Enjoy! Chris Quote Link to comment Share on other sites More sharing options...
mustang guy Posted November 24, 2011 Share Posted November 24, 2011 You have the beginning of a world class surround system. If you add either another Heresy or a Belle Klipsch for a center channel, you will have a surround system that would rival any $20,000 surround system out there. I would love to see some pictures.

moray james Posted November 24, 2011 Share Posted November 24, 2011 here is a happy camper. Probably more than you want to spend. Your Dad`s speakers are extreemly high end units and are worthy of fine amplifiers to do them justice. Used amps by Rotel Adcom Nad and others are inexpensive units which will sound good but are not in the same league as your fathers Khorns but they will sound good and you can decide how far you want to go with his hobby. I think he left you a wonderful gift that you are likely to enjoy for a life time so judge what you spend by that.

Bubo Posted November 25, 2011 Share Posted November 25, 2011 John, The K-horns and Heresys are as good as it gets for speakers regardless of how much more you spend. What makes these speakers special is that you don't need a huge amp to drive them, they are remarkably efficient. At 2 Watts the K-Horns will run you out of the room, at 50 Watts out of the house. Most of your listening will be at less than 1 Watt, even if you are hard of hearing. A high quality integrated amplifier that puts out 25-40 Watts is all you need. If you only want stereo, look at the class A amps. Tube or solid state the possibilities are endless. Since you aren't spending the money on watts to drive pig speakers, you can spend it on quality. Especially good characteristics at very low watts. If you want surround sound, get a THX rated amplifier. I have used my La Scalas with 2 Pioneer Elites. I highly recommend the Elites, you can hear them at Best Buy Magnolia. Entry level for a 7.1 Elite is about $650 and with the Klipsch speakers, it will blow your sock off. THX sound and video ratings mean something. To play Blu Rays you need DTS decoding, so you are talking new. My $1700 Elite did sound better than my current $650 Elite. Lawyers are sucking me dry. Killer 5.1 sound; As one of the other posters said, the K Horns are the two front speakers, Heresys in the rear and you have to get one more Heresy for your center channel. Why, because the Heresys are voiced the same as the K Horns. You system will sound better than any theater you've been in. You won't need a sub woofer, the K Horns have 15 inch woofers and the Heresys have powerful 12 inch woofers, you can make the house breath. If they are old enough, it may be time to get the capacitors replaced on the cross over circuits inside the speakers. There is a well known guy on these boards that specialized in updating the boards. If they are 30 years old, its time. Quote Link to comment Share on other sites More sharing options...
Bubo Posted November 26, 2011 Share Posted November 26, 2011 http://www.audiogon.com/cgi-bin/cls.pl?miscrcvr&1327118180&/Pioneer-Elite-vsx-94txh- This is a good example of a quality receiver for little money. My guess is that the owner is selling to get the latest codecs for blu ray. IMHO this would knock your socks off with your speakers. Audiogon is a good place to shop for units like this.

deafbykhorns Posted November 26, 2011 Share Posted November 26, 2011 I believe Paul Klipsch favorite amp was a 2A3 based tube amp Try the Bottleheads, they are very reasonable Quote Link to comment Share on other sites More sharing options...
Bubo Posted November 28, 2011 Share Posted November 28, 2011 Any suggestion on the 2A3 amps, manufacturer and models? How much is reasonable? I looked and there are a lot of them out there. Is 8 watts RMS enough?

Bubo Posted November 28, 2011 Share Posted November 28, 2011 Thanks, I read the letter from PK. If I read it correctly; He states that abandoned tubes for solid state and that he owned a Crown D-60 http://www.ebay.com/itm/Crown-D60-Stereo-Amp-/150690227702?pt=Vintage_Electronics_R2&hash=item2315d665f6#ht_2075wt_1388 Quote Link to comment Share on other sites More sharing options...

Chris A Posted November 28, 2011 Share Posted November 28, 2011 Thanks, I read the letter from PK. If I read it correctly; He states that abandoned tubes for solid state and that he owned a Crown D-60Yes, that's what I read, too. Nowadays, I believe that many here are looking at Crown D-45 and Crown D-75A amplifiers (twin designs except for the output power transistors), especially with the slew rate upgrade that Mark Deneen (former owner/chief engineer of Juicy Music) did. Mark is fully retired now, but there are folks still upgrading their amplifiers. Chris Quote Link to comment Share on other sites More sharing options...
moray james Posted November 28, 2011 Share Posted November 28, 2011 The older amps you are looking at are nice old amps but unless you are into that quality new designs are a far better value. The Allnic intigrated amp is a stunning design and will deliver 12 watts a channel of bliss from a SET 300B. Probably the last amp that you will own. Check it out. By todays standards old Crown SS amps sound disapointing. Contact Dave as he is the North American Distributor. Dave is a good guy to deal with. Hope that this is of interest.

Bubo Posted November 28, 2011 Share Posted November 28, 2011 http://www.thx.com Great place to research a THX rated receiver, the rating means something Also a good article on Amplifiers on wikipedia addresses tube vs sold state amps concerns like TIM distortion Quote Link to comment Share on other sites More sharing options...
Taz Posted November 29, 2011 Share Posted November 29, 2011 I have some old 30 watt tube amps. One night I was not in good mood. Turned the volume straight up, I'd guess 15 watt? Wife came from other end of 6 bedroom house to complain that people weere trying to sleep. Way too much volume to listen to most the time. I've never opened up to the full 30 watts. The Khorns are Great speakers. I never thought I'd be lucky enough to own a pair. Count yourself as lucky, and keep both pair![] Quote Link to comment Share on other sites More sharing options...
Bubo Posted December 1, 2011 Share Posted December 1, 2011 I downloaded PKs Dope from Hope papers and am reading them. He repeatedly states his concerns that 100W amps will tear Klipsch drivers apart with surges if anything goes wrong with the amp. He states that 25 to 40W is plenty to protect the speakers and suggests that quality is better than quantity for Watts. I keep the gain at 50% on my Mac Stack Amp as a safety measure. Hope this helps. Quote Link to comment Share on other sites More sharing options...
russ69 Posted December 2, 2011 Share Posted December 2, 2011 John, Khorns and low power amps are very much like a fine wine, it's an acquired taste, and may not be the way to go for your very first system. Your palette may not be at this advanced level. If you have never fooled around with hi-fi, you'll probably want some power to fully see what a Khorn can do, later you can decide how much is enough power for you. Do you have a budget in mind?
