Well, this thread has certainly taken a life of its own... I'm not sure that I've been swayed one way or the other by the arguments presented pro or con, however, I'm picking up a 40 year-old NAD 3020 this evening for $90. It will likely need a refurbishment, e.g., a squirt of DeOxit in the pots, refreshed capacitors and hopefully not, the dreaded power transistors, which, if its made it this far, have been rectified. as shown in the photo I posted earlier in the thread, my Heresies aren't entirely ideally placed; in a perfect world, I'd have them about 10-12 feet apart, in corners, but that's not possible without entirely rearranging the room and incurring the wrath of my partner and cats for obscuring window access for her plants and their views of the birbs... so, to possibly improve on the staging, my thought would be to place satellite speakers in the corners of the listening space, to accent the staging for both 2-channel and 5 channel, with the Heresies doing the heavy lifting with the 3020.

reasonable offers accepted.

That’s the plan. I may even have another pair to throw in the mix, if they’ll fit in my car. I nearly became that demographic. A decade ago, I left philly and went back to my home town after a mixture of health issues and related debts and the lingering effects of the Great Recession proved to be a bit much. I packed up all my stuff (except the heresies, they wouldn’t fit) and went back to Iowa. After six weeks in the midwest with winter approaching, I realized that I’d made a terrible, terrible mistake and got on a plane back to Philadelphia with my laptop, bicycle and 3 suitcases of clothing. I left my receiver, satellite speakers, kitchen gear and tools behind, thinking I’d be back to retrieve them in 6 months. That never happened. I’d gotten burned out and bored with music and didn’t have any friends that shared my interest anyway, so I did without. Eventually, I picked up a Bose wave radio, which sounded good enough for streaming Netflix with a 1080p projector and started listening to more music. When I inherited a receiver, subwoofer and speakers from my employer, I suddenly remembered I had the H700 Heresies in my carriage house, and here we are: I now have a turntable, I’m buying records and obsessing about audio in ways that I hadn’t in years, decades, even.

oooh, for some reason they didn't show up when I searched. It's a little bit of a haul- oddly enough, 20 miles to someone living in a city is perceptively farther than 20 miles in the suburbs, or as they say here in Philly, "everywhere in Philadelphia is an hour away from Philadelphia." I'll see if I can plan a trip out there some Saturday for a listening session. Judging by their online inventory, they only seem to have Cornwalls in stock, but that may do. that may do.

I live in a condo and rarely listen to anything above 85 dB. That's politely loud in my book. the room is an open space that's about 20' x 25', comprising of a kitchen, dining area and living room/seating area; the seating listening area is about 14 x 10, the speakers are about 7' apart, aggressively toed, 12 inches from the wall and in corners, as much as possible. while we have hardwood floors, there is a rug in front of the hifi. the only bare walls are behind and above the hi-fi credenza, which I use as a projection screen. Overall, I would rate the space as acoustically neutral, mostly because it's packed with furniture, wall hangings, curtains, plants and such, with little in the way slapback echoes or sonic artifacts. My Denon receiver sounds fine to me, but I have a nagging wonder that it could be better. I'm not likely overwhelming the power, but I would like more adjustment capability and the UI on my receiver is not particularly intuitive, I don't have a manual and I'm not sure if I have the bandwidth to download it and fiddle with everything. Part of me has vintage inclinations to get something to match my 51 year-old Heresies, so I'm largely looking at things made between '68-'82. another part of me is parsimonious to a fault and reluctant to spend the asking rates for vintage kit these days. So to balance that out, I've been curious about a few NAD amps in my area that I've seen advertised: the classic 3020 integrated amp- the original '82 version, a newish C 316BEE V2 that seems to embody the spirit of the 3020 and a 7240PE receiver from the mid 80's. The 3020 has some really appealing attributes which seem to balance the pros of the early solid state era, while serving as a bridge to the modern era; it would certainly be sufficient to drive my Heresies, but the downsides are their age and resultant scratchy pots, tired caps and power supply issues that have presumably been rectified if it has made it this long. The 7040 is somewhat from the same era and has many of the same characteristics of the 3020, but more power, although it also has the same minuses, plus a tuner that I don't really need. That leaves the C 316BEE V2 which has the simplicity of the 3020, but being newer, has ostensibly better reliability & more power, but does it have the same mojo? at any rate, all being well under $300, they're cheap enough to scratch my itch to see if the concept is worthwhile, but have audiophile cred that belies their low price. any thoughts?

I'm realizing that as these woofers break in and start to come into their own, that I should probably change my subwoofer crossover frequency. I previously had it set around 80Hz; @ClaudeJ1, based on your graphs, what would you recommend for a revised x-over setting with the Eminence Delta Pro 12a?

I stopped into my local Worldwide Stereo, who are listed as Heritage dealers. I was hoping to hear both the Heresy IV and Corwalls to get a reference point for my recently refurbished Heresy H700's. All the store had was a lonely pair of Fortes; checking the regional inventory, the next nearest store had a negative inventory- numerous back orders and no stock. That was disappointing, to say the least. further insult to injury, at least two of the other dealers on the map in the Philadelphia area no longer carry home audio to any significant degree, let alone Klipsch Heritage speakers. edit, make that the 3 other stores. One, Microcenter had a small selection of Surround systems in their TV department, the home audio dept is long gone; another store sells personal electronic devices in the airport, while the 4th has pivoted from a hi-fi store, to a smart home solutions team. While hi-fi is part of their offering, they no longer have a retail presence, but have shipped their store to a home design center.

I currently have a Denon AVR that sounds great and does everything I need it to, but I've been seeinga lot of mention about having a dedicated two channel receiver. What's the benefit? also, is there an advantage to vintage 70's gear, which is all the rage these days, vs amps and receivers from the 80's and even now?

That will happen in due time. Give me a few weeks; once I sell a few spares, I’ll get them ordered. 😁

Caught it. Much better. Thanks for pointing that out, Cranky Solder Meister!

Ok, with the delta pro woofers, insulation, upgraded network and port, these speakers are everything I wanted, but didn’t get when I pulled them from the dumpster on my jobsite, 16 years ago. I powered up my receiver and turned the subwoofer off, played a few tracks and my partner immediately remarked that they sounded better. She was shocked when I told her that the subwoofer wasn’t on. I did have to turn up the bass on the tone controls from flat to get the sound I wanted, but it’s only up 2dB out of 6 on the receiver. Acoustic music sounds especially good, as does electronica, instrumental hip hop and post-rock. vinyl sounds particularly good, although the mids seem slightly scooped, but that could also be the mix or the mastering.

How so?

Oh, the port has been in since Friday! Next step will be upgrading the tweeters, but that will have to wait for October.

And here we go. I’m only putting these in temporarily with 4 screws because I’d rather not put more holes in these 51 year-old cabinets. I have something else in mind. 😁

I have a Klipsch K-77-M in excellent condition with leads; simply drop into your cabinet and go. $80, plus shipping.

bumping this up...

After. Couple hours listening with the ported H1’s, I’d say that the mids are quite pronounced. Perhaps too pronounced. I may put the eminence delta pro 12’s in tomorrow morning and see how they play with the E networks. I expect that the B network may be the thing to tame the mids, but we’ll see when the delta pros go in.

I converted a pair of Type A networks To Type E: right away, the mids are warmer, less sibilant. Overall, the speakers sound less harsh, and much warmer. It’s a definite improvement! for giggles, I put the 3/4” ported backs on the cabinets, with the K-22-K woofers still installed. A-B-ing between the stock speaker, the ported one seems louder, with more presence in the midrange and just a hair more bass. I wish I had the analytics kit to measure my perceptions, but it definitely seems like an improvement. when I make the final version out of Baltic birch, I’ll move the port slightly inward. Next step is to install these: $200 for the pair, one is in an unopened box!

They read 7.5 & 6.5. Seems normal.

oh, I will, but because this is my first attempt, I want to go through all the steps to understand how each change affects the whole. I get that it’s reinventing the wheel since you’ve done all the hard work for us already, however, this is how I learn best. I’ve read every page of both super heresy threads, plus several other build threads and much of the crossover threads. I’m just beginning to grok the latter, but I’m a little bewildered by it all. While I can repeat much of the information I’ve taken in verbatim, until I’ve actually done it, I won’t understand it completely. Basically, I’m an artist and craftsman, not an engineer: I work with concepts and ideas and turn them into form, but I frequently deal with the concrete by feel and intuition, not calculations and numbers. As such, I’m reliant of the proofs and methodologies that you and your kind develop, but must attune my intuition through experience. It’s the exact opposite of your approach, it’s sloppy, meandering and occasionally ad hoc, but this is what works for me and more importantly, I find it enjoyable. I deeply, deeply admire how you reach your conclusions and results, but for how my brain functions, somewhat randomly and by free association, your methods would leave me muddled and miserable. 😂 basically, I can’t do anything the easy and straightforward way.

I studied with Lowell Cross at the University of Iowa in the 90’s. He did a number of classical recordings with ambisonic mics. The results were remarkable.

They arrived in the mail today. Here’s the weird thing: they have sequential serial numbers and Klipsch labels. I’ll pull out my multimeter later and get a reading on them, perhaps the seller got the reading in error.

Not mine, I say them on eBay and thought I’d share them here in case we have members in the area who would benefit. The price is right. https://www.ebay.com/itm/125456605528?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=gRQJlLtxRNy&sssrc=2349624&ssuid=IsKyqsUxROW&var=&widget_ver=artemis&media=COPY

I have a pair of Klipsch K-22-K 8 ohm speakers that were pulled from a ‘71 H700 Heresy, but I believe them to be newer replacements. One speaker is in good condition, while the other has a dented dome and a cone that has been torn and patched with rubber cement. It would be a great candidate for reconing or for parts. $100 plus shipping in the continental US. Or pick up in Philadelphia, PA.
