not crazy about the color of the stain that was used . . .

the type e crossover is really easy to follow -- just use the diagram below and follow the circuit on your board. as you can see there are three things happening: (1) the woofer has an inductor in front of it -- this serves as a low pass filter (2) there is a capacitor in front of the autoformer that goes to the squawker and the tweeter. this is a high pass filter, the frequency is based on the value of the capacitor and the impedance it sees and is primarily driven by the setting of the squawker and the impedance of the squaker. (3) there is a capacitor in front of the tweeter. again this serves as a high pass filter for the tweeter. for a super heresy, what you need to change is based on your woofer choice. if you use the dayton pa310-8, you need to make no changes to the crossover. i really like this woofer and since its the cheapest i think this is a no brainer. the other options have a higher output so you need to increase the output of the squawker and the tweeter, so you need to move both up one position on the autoformer (i.e. move the squawker on 3 to 4). moving the position of the squawker on the autoformer changes the impedance and changes the high pass frequency with a 2uf capacitor (the one in front of the autoformer). to compensate for that, you need to change that capacitor value to 4uf to maintain the original high pass frequency. @ClaudeJ1 explains all of this in one of his earler posts in the super heresy 2.0 thread.

@Gypsy -- what are you confused about? what model heresy do you have?

i haven't ever tried to remove those on a klipsch speaker. on every speaker i've had, i've used a small jewelers screwdriver. they're small enough and the tips are sharp enough that i've been able to easily pry them out. https://www.amazon.com/Precision-Screwdriver-Electronics-Computer-Repair/dp/B07PV5D3VV/ref=sr_1_5?keywords=jewelers+screwdriver+set&qid=1652881478&sr=8-5

that certainly could be true -- i've only used them in non-critical situations. i can say that build quality is great. i typically use the furman pl-8c (particularly for rack mounting situations) because they're basically bulletproof and audioquest niagara 1200 for more critical listening situations. the great thing about the zero surge is the non-sacrificial filter technology, so if you don't need rack mount it seems like a good choice. both the pl-8c and the zero surge 8r15w are about $300 (this item in on sale on the zero surge site).

for a more economical choice, i'd also second the tripp-lite isobar products: https://www.tripplite.com/isobar-8-outlet-surge-protector-12-ft-cord-3840-joules~ISOBAR8ULTRA i'd go with the zero surge if you can, though.

i second zero surge -- great build quality, non-sacrificial, not very expensive: https://zerosurge-com.3dcartstores.com/8R15W_p_15.html

SOLD !! Thank you @Outrider 6! It was a pleasure to meet you in person. Save travels.

Beautiful work!

and youtube from a cable box is even worse . . . you have to listen to a high quality source and a high quality amp to see how your speakers sound. sounds like you need to switch out each of your components and see which one is the culprit.

@Tanner. -- speakers look like they're in good condition and the drivers appear original (i'm sure some of the forum experts can confirm whether the woofers are original or replacements). the grills are definitely NOT original and certainly the speakers don't look like heresys with them on. needless to say, the pegs aren't original either. i'd guess they were made in the early 80s.

yes! but i actually came down the hi-fi affliction many years ago when i was 10 years old -- the klipsch variant is new! 🙂

I think you've got people confused -- Claude is the innovator who's been researching and reporting on the opportunities for enhancing Heresys through the threads below. Claude, along with many others, love the 3012ho speakers. Above, Claude said "These are the very best woofers to convert 40+ year old Heresys into Super Heresys." I'm selling the speakers because I enjoy learning and experimenting -- Klipsch Heritage speakers are a great platform for that. So things come and go. My specific decision is to reallocate these funds towards some Cornwall Is (when I find the right pair).

sorry, that wouldn't help me much. i need to sell both.

Get these hard to find speakers quickly! Only played 2 hours and are in essentially new condition. Would have returned them to Parts Express, but I did install them so there are a few tiny marks on the gasket next to four screw holes (so I can't return them . . . ). Since they're so new, of course I have all of the original packaging! They're $420/pr from Parts Express (when they're in stock). Price is $350 for the pair. Cash, please. Hoping to find a buyer in New England so can arrange a direct drop-off. Prefer not to ship, but PM me if you want to discuss! FYI -- I'm also jcn3 on Head-Fi and Audiogon if you want to check out my feedback. Thanks!

@thebes - tv-14 is the rating of the film. Looks like it can the rented on Amazon Prime Video and Apple TV.

@mboxler i've been wondering about the de-120 sensitivity too! i'm using dave a's smahls with the de-120 tweeter. i was measuring my heresys at the sitting location and got the graph below using dirac. note the drop after 5khz.

BEAUTIFUL! Great work!

there's some sort of issue there -- the two tags have the same serial number and are written with different handwriting. the serial numbers would be different, but sequential and i would expect the handwriting to be the same since they were manufactured together.

Think that's legit? Only stock photos and weird pricing . . .

Here are the pics. They're pretty small pics. I'd replace them on Postimage with better ones.

another doc:

very pretty, but quite pricey!

did you look through this thread: and this thread?

those speakers are from 1978. the paper surrounds look right, but i haven't seen that cone color before. having said that, the color on the surrounds of my k22 are not that common either.
