Is the Heresy 4 ohms? I thought t was nominally 8. I never measured mine...

How long have you had it? (Wondering about like expectancy) Thanks

I have got a bit of a tube bug. I am currently running some 1983 Heresy I's with a Yamaha 5.1 receiver and one or two 10" powered subwoofers. (I own two subs but one seems to sound just as good so the second sub is currently used elsewhere.) I don't have unlimited funds. Some options: Tube Depot Cube 7 - 3.5 watts per channel, all tube (not the power supply), no sub out - $180 Dayton Audio HTA20BT - 20 watts per channel, tube preamp, digital power stages, sub out, $130 Dayton Hybrid HTA100BT - 100 watts per channel, tube preamp, digital power stages, sub out, $165 Future possibility, assuming I fall in love with tubes? Three Tube Depot Cube 7 amps in a tri-amp with the Heresy speakers (I would need some kind of active crossover before the amps) thus total cost would be 3x$180 plus the crossover. I am interested in your opinions. If your opinion is "Forget all of that and buy something more expensive!" I will listen, please give details why. If your opinion is "Forget all this and just put the money into Cornwalls and remain solid state" I would also listen. I am new to all of this.

Currently one Heresy is on an old chair and one is on a milk crate. Yes, I live in that kind of a neighborhood. A 10" powered sub sits between them. I just ordered a second, identical, powered sub. I will build two lovely stands that allow "stacking" without actual transference of vibrations. I will test with one and with two subwoofers. I can't exceed 160 watts with my current equipment (not counting the powered sub woofers.)

Nice, I can make those for a lot less than $42. (My free time is worth $0, and I need to justify an expensive collection of power tools.)

The Heresy stands I see in the old pictures look about 3" tall and tilted back. More modern and homemade Heresy stands look like a foot or so tall. What do you all like? Thanks

No, we had had no electronic contact. I saw him last pre-internet.

Facebook suggested a friend to me, my cousin who I had not talked to in 20 years. We have different last names, live in different states, we had no mutual Facebook friends or mutual liked pages. How did they know?

I love that! They will actually make no holes at all, the pins will pass between the fibers of the cloth.

My super old Heresy speakers came without grills. I bought cloth from Crites and made grill boards from Masonite. I have now installed cloth on one board. I have reproduction metal Heresy badges. What is the best glue to put them on the grill cloth? Thanks

On a cheaper note I use R-51PM’s with a sub and I like the result. It was my computer system until my wife stole them all for her TV. Your idea makes sense.

I love that song. I was sitting at my computer, I had to go play the original 1967 version. Lots of distortion on my Klipsch Promedia 2.1 during the loud organ solo. It seemed like the tweeters/mids were being overdriven in some frequency. I need to go play the same stuff on my Heresy speakers and see how it does. The distortion might be in the recording. Last time I heard this was probably on a 6"x9" car speaker. Edit - The Heresy's sound a lot better, no surprise, but there is a lot of distortion in the organ. It was certainly meant to be there but it confuses the small Prologic speakers, the Heresy speakers just reproduce it without any trouble.

I found a great article about heritage series speakers but it does not seem to cover pro speakers. My Serial number would imply 1989 if I use the Heritage formula, but KP-250's were not built in 1989.

Serial number is 8999093 Thanks!

I'm an old dude, came back to stereo recently. Bought a pair of Heresy speakers, I am restoring the cabinets. The small screw terminals are too small for 16 gauge wire and the screw driver slots in the screws are so shallow that you can't get a good grip. I'd like to convert to banana plugs. All the premium banana jacks and plugs are metal. This concerns me, something could fall across the two plugs and short the amp. Plastic seems safer but all the cables with plastic plugs seem cheap. Am I over thinking this?

I have a Polk subwoofer and have used it with Klipsch Heresy' speakers and also with Klipsch R-51PM speakers. Works so well that I may buy another one so that both pairs can share the joy.

I bought two Heresy speakers. I believe from 1983. The outsides are rough, they sound good. There were no grills. I bought the proper cloth from Crites, I bought logos, I bought Masonite for grill boards. I opened one speaker, the plan is to use the motor board as a template to rout the grill boards. Everyone talks about re-capping. My capacitors look pristine. The entire inside looks pristine. I expected a lot more dust and crud. I have attached pictures. My thought is to make the grill boards and button this back up. I will probably stiffen the back but not try to stiffen the sides or motor board. There is not much room on the motor board and tap tests reveal the sides to be much stiffer than the back. Stiffening the back without eating up much volume will not be difficult. I'm a mechanical engineer in the Aerospace industry so I stiffen things for a living, I have also built a few dozen wooden drums. Thoughts on the capacitors or any other ideas? Thanks

Look great! I’d like to see a picture of the back brace. Also are they veneered? Was there any damage to the veneer?

I'm also interested. I just bought a pair from '83, they sound good, but I have no idea what they sounded like new. I guess step one is to open them up and look inside.

I bought a Yamaha RX-V385. Long term it might go to the TV room (I watch little TV) and I would then get a serious integrated amp. But the current Yamaha sounds good, in 2-channel or 2.1 or 3.1. I should try it with a movie and dialog, but my real test of TV speakers is a live NASCAR race. Interesting factoid, my Yamaha happily simulates a center channel when I tune to FM on the built in tuner in the receiver. But I plugged my 35 year old NAD analog receiver into it (since it is analog it has to go into AV2 or AV3) and it reverts to 2 channel only. 2.0, not 2.1! So I cannot A/B the built in receiver versus the NAD except in 2.0 mode. I am looking for a way to fix this but I cannot seem to find a way.

Thank you for all the historical info, it is appreciated and very interesting. The room I am in is 16 x 25 feet and I would most likely only be allowed to set the speakers up on the short wall (my wife is very tolerant of all the strange junk I buy but the room is also hers.) The room is currently arranged so only the short end is available. I might someday rearrange to set the three speakers (two Heresy and one nearly identical KP-250) up on the 25 foot wall to see what they sound like. I am more interested in the historical aspects than in some permanent optimization. So I will try the PWK method and my Yamaha's unknown algorithm. Right now, on the short wall, the 3.1 system sounds good, but I cannot claim that it is "better" than the 2.1 system without the center speaker. It is different, but not necessarily better. And I have not set up PWK's box, nor do I have a center channel amp. So it is just the built in Yamaha algorithm now. Long term the single KP-250 probably goes into a gutted 1920's radio cabinet to make a super-mono radio. As I said, my wife is very tolerant of my strange junk.

2mm on each side? Thus the cutting dimension for the board would be width (or height) of the rectangular opening minus 4 mm minus 2x the thickness of the cloth. Cloth thickness is probably negligible. Thanks!

First off, is grill boards what they call the panels that support the grill cloth? I bought some Heresy speakers with no grills. I bought fabric from Crites and metal logos. I now have the Masonite hardboard material. I know that it must be smaller than the rectangular hole that it sits in. How much smaller? At least by twice the thickness of the cloth that will wrap around the board. How much more than that? And the holes for the speakers - Is the correct size exactly the same as the outlet of the speaker or a bit larger? How much larger? Thanks

In order: R-51PM’s - Bought for my computer early in the COVID lock down. R-51M’s - bought as a gift to my daughter who had a vintage receiver and needed speakers. Heresy Ones, bought on the internet. Just because. KP-250 (singleton) bought on the internet because it was stupidly cheap. I will experiment with it as a center speaker but might also put it inside a gutted 1920’s radio cabinet. I wouldn’t disassemble it, just sit it in there and hide it with grill cloth. R-51PM’s were stolen by my wife as TV speakers, “just for the Christmas season.” I may never get them back.

I just bought a pair of Heresy speakers from 1983. Step one, what are the stiffening mods?
