Great looking speaker. GLWS!

I would look at Lexicon, Arcam or Rotel. The former 2 especially have all the DIRAC bells and whistles and will do all the current formats. In your case for 5.1 you'll be getting at best TrueHD 5.1/DTS-HD MA 5.1 layer embedded in Dolby Atmos and DTS:X streams. What I like about Arcam is they offer better support than others for legacy lossy digital surround formats like DTS-ES. Also keep an eye out for JBL Synthesis stuff which is mainly used in pro installs and mostly rebranded Lexicon, Bryston, Trinnov etc. you can sometimes get unbelievable deals on those pre-pros. I personally don't like the Audyssey, DIRAC, Yamaha YPAO etc. stuff as I find that DSP to be invasive and muck up the sound. I'm more a believer in physical room treatment and a processor faithfully decoding and reproducing the source as pure as possible. But if you want DIRAC or similar, I'd basically look at the Harman family of brands for your pre-pro. Good luck!

Not sure what KHorns they are though, assuming older so they will be open back and will need a perfect corner for them. Very tight fitting corner otherwise you will need to make false corners for them or modify the bass cabinet to make it closed back like how the new ones are which still need a corner but don't have to be perfectly sealed they just need to be in the vicinity. The crossovers may also need replacing too depending on the age too. Belles are fine just along a wall like a Cornwall or Forte. If that's not something you can do or can't make work due to the room then the KHorns may not be ideal. I would personally do this if you can make it work though and if the speakers are in great shape. KHorns + the Belle for the center is a legendary combo not just for HT but equally as much for music. That would be a pretty substantial upgrade over the 7s and the 504 center IMHO. Especially the center. The RF7s are really good speakers though, especially the IIs and IIIs. It would make a fantastic surround speaker for those 3 up front, you'd have basically 5 full range speakers in that system so you can just imagine. Voicing of the 7s though may not be a 100% perfect sonic match compared to heritage so you may have to fiddle with the EQ a bit. Perhaps not, YMMV. Aesthetically of course they look very different but if that doesn't bother you then I would very much consider doing this.

I don't know about older KHorns and Heresy's but all I can tell you is the Heresy III is a phenomenal HT and music center between 2 AK5.5 KHorns. Main thing is just having the height/position of it right relative to the seating position. With the slant base it has far enough away the Heresy sounds like it's coming from TV level like the KHorns. If you are too close to it it may be an issue though as a center, so you will have to elevate it a bit. Voicing on it is a perfect match on mine and the LCR sound stage is seamless with movies. I actually have custom Aussie Walnut Forte IV's on order for my corner surrounds to upgrade to 6.2 (I use 2 subs). Down the road will eventually add 4 heights for Atmos/DTS:X and Auro. But for now I will be happy going from 1 to 3 surrounds as I've been running LCRS aka 3/1.2 for 2-3 years now. But between equal rough time period and model, the Heresy is an excellent center between them. Dialog is crystal clear and it actually helps with upper frequency extension since the H3s extend to 20kHz where as the KHorns fall off after 18kHz. Not that you can really hear that anyway as lots of great cinema horn systems also roll off above 18kHz as well. But to be honest when I initially just ran 2ch HT with the KHorns, they really came alive even more when I wasn't relying on them for phantom center anymore when I added the 2 H3 70ths to my system. I have the Heresy III's crossed over at 60hz, to give them a bit of padding before they fall off and on my pre-pro depending on the source type I have that set to redirect to the KHorns for music and the subs center channel bass management with films, both modern lossy/lossless discrete surround and older matrix surround films from the 80s. Now there are a lot more options for you as in the late 80s you also had the Belle's too which are a killer center for KHorns. Really just depends on your room layout, console/furniture considerations etc. Because at one point or another in Klipsch history, the Heresy, Cornwall, Belle and La Scala's have all been used as center channels for the KHorn and all will do the job. The latter 2 especially in wider stereo arrays primarily for a 3ch stereo system for music. Something that still sounds amazing even with the Heresy -- which I know first hand since it's how I exclusively listen to music with it... with a custom PWK box made for me with an adjustment gain for the center. Music DSP in modern Pre-Pros other than Meridian is horrible, especially Atmos/DTS:X ones. You'll enjoy music a lot more in passive 3ch than using the very generic "improved" DSU or DTS Neo:X upmixers. Neo:6 Music and PLII Music are not available in Atmos/DTS:X capable AVR/Pre-Pros, but the passive 3ch sounds better for music anyway, and better than straight 2ch IMHO. There were also some other bespoke models in the 80s and early 90s that Klipsch no longer makes that also may work as a center as well for late 80s KHorns, but I'd probably stick with the heritage "legacy" line of models for the reasons state above -- they've all been used as center channels between KHorns at some point in different systems over the years with great success. Space/footprint wise, the Cornwall and Heresy will be the most friendly, and both are also enclosed of course too. The La Scalas and Belle's stick out a good amount. The low end of the Cornwall would be the best out of all of them. So if you can fit them, the Cornwall would be my choice, and the Forte or Heresy for your side and rear surrounds. Good luck!

Yeah I wanna know too ^^ If it was a business jet that would be totally insane. Military I could totally see that, especially in something agile like a Hornet, F16 or Raptor.

@jimjimbo That's what I was thinking. But I'm not on Facebook anymore, deleted it long ago. Don't really have much interest in going back on there again to be brutally honest lol.

That is so cool! I was surprised to learn ironically someone had the RC64 III made in Australian Walnut a couple years ago, a dealer actually ironically to be a matching center between 70th KHorns like I have. But seeing how awesome that turned out really gives me high hopes! Awesome job

Still trying to acquire a pair of these, so thought I'd bump this after a few months that I am still interested incase anyone has a pair available for purchase! So far I have had 1 PM response from a scammer here, and 1 response from a scammer on Audiogon. I'm not renewing the Audiogon ad. 0 for 2 lol. Will give this about another week or 2 before I ultimately look to go in another direction, a far more expensive one. I ended up selling 2 GPUs I had on eBay taking advantage of the mining markup prices right now to have the extra funds in place incase I end up going that route. But much prefer this plan of course. Anyway if anyone has a pair they may want to sell, perhaps to make room to upgrade to a new Heritage model let me know! I will give you top dollar for it, especially if they're in great condition. Thanks so much for looking.

BTW just as an update as promised. I was able to acquire this grille fabric. The Acoustone grille fabrics, including the P9000 model is made by Newcastle Fabrics and they have it. They sell it by the cubic yard. I received it a few weeks ago. And ordered a decent amount to be able to use and make for any large size heritage speaker. Ordering was all via email and they took a couple weeks in between responses but it all worked out and is identical to the 70th Anniversary Grille. They themselves confirmed it to me via email that they are indeed the original manufacturer of the 70th anniversary grille fabric. I should also be receiving the custom RC64 script badges I had made sometime next month as well by the gentlemen that Randy recommended in Russia. We worked together on the exact design and sketch. Also had him make me a script "Klipsch" one but without the "orn" in it as well. Looking forward to getting the Australian Walnut RC-64 III I ordered from Paducah HT. Ended up ordering an extra stock grille to have the one black one as back up. Will use the framing of the stock grille to put the P9000 grille fabric over it and emblem. Which goes to my final question. What is the best adhesive/glue to use for grille fabric installation? On the Heritage models and Anniversary speakers with the metal mesh grille, you can see how around the back edges where they fold the grille and glue over it. It reminds me of the epoxy used in carbon composite material layers construction. Does anyone know the best epoxy/glue for this application? Or is there a specific one I should use for this? Thanks!!

I used to love Marantz equipment in the 2000s, but IMHO the brand isn't quite what it once was. Klipsch speakers aren't particularly amp picky in my experience, I have found the digital front end or analog source equipment to make more of a difference. That said though I have found Bryston and McIntosh to really be my go to amps for Heritage. Since heritage is super efficient they don't need a ton of power but enough where you have plenty of headroom and then some. Really any McIntosh from the last 11-12 years to current is gonna have their newer more transparent sound. I find Mac's older solid state stuff to sound far too mushy, warm and laidback. I used the MA5200 (has no Autoformers) for about a year and a half when I was strictly running 2ch with the KHorn 70ths and it was glorious. Dynamic, powerful, wonderful clarity and detail... just delivered the goods in spades. When I integrated a few more speakers to merge HT and 2ch and picked up the MC206 6CH power amp it was a massive disappointment. Reason I went for the older 206 over the much newer 205 or 207 is the former being quite a bit less tall and fitting in the 7 5/8" opening and 8.1" total clearance in my media console. I figured it would sound like the 5200 just with 6ch''s. Boy was I wrong. Totally different sound signature. The newer Mac amps sound so much better. Like 10x better. I always loved Bryston analog and digital equipment and have found Bryston and Klipsch to be an amazing pairing especially for dual HT and 2ch use. Super transparent, clean and powerful sound. Not harsh in anyway, music sounds fantastic. Heritage I think benefits clean power solid state to help with bass extension and give them a bit more punch, slam and power with as flat and clean as frequency response as possible. Ended up with the Bryston 9BSST2, and low profile compared to the 205/207 so fit with opening in my media console. Has that new Mac sound but with 5ch outs. Would have loved to get the 205/207 but system/setup requirements made me go elsewhere. My entire digital front end and source components are all Bryston now with the exception of the Oppo. Amazingly built stuff. Not as flashy as Mac, but performance is right there with new Mac gear, probably even better. That said, I think you would absolutely love the MC205 or MC207. I would definitely go in that direction and not even think twice about not having autoformers on it. It will still be very musical and will get out of the way and do what it needs to do. Shortly before the pandemic I heard the MC205 during a demo and was really impressed with it, sounded a lot more like the 5200 I used for awhile, which doesn't have the autoformers as I mentioned and loved with the KHorn. Generally speaking Heritage sounds amazing with Class A and Class A/B solidstate. Accuphase, McIntosh, Bryston etc. All really good stuff.

Awesome lol. Congrats and good luck on hunting down those!

Sell it on eBay. You'll probably be able to get more than you paid for it with the GPU and chip shortages right now. You'll be able to put those funds towards a Mac or a Primaluna.

Wow that's really neat. Congrats on the vintage KHorns.

Not interested in big bugs are whatever they are using as a substitute for the protein. Tried it a few times, it's just not the same. This is a bridge too far for me. Just my 2 cents...

Great setup. GLWS!

@moray james Good to know, thanks for the heads up. Indeed, the craftsman ship of those stands looks truly on point. Shame they can't make them taller but things are moving into place as far as finalizing how I will finish off my heritage HT system, so I may end up being able to utilize the shorter stand size. Thanks again for your amazing suggestion. six

Very interesting appreciate all the responses and ideas @moray james That's exactly what I'm looking for. But higher. I took a look at Skyland and those are perfect. I'll reach out and see if he would be able to make me a 36" high one as I have my Heresy now above ear level in the back and I like the effect that provides. I use Aragosy 360is with my Focal Studio Monitors in my office, and just discovered they have a different 36" model with a base suitable for a Heresy. But I like the quality of those Skyland stands and how they are filled and dampened. Really nice stuff. Thank you so much guys... this is why this community is the best!

No kidding lol

Just wondering if any of you guys are aware of surround speaker stands that are suitable to hold a Heresy III or any Heresy for that matter? I currently use a make shift multipurpose rack cart on wheels for my rear one, but looking for a more permanent solution long term solution when I have more Heresy's back there. Currently the height to the base is 40" from the ground and looking for something that would be about the same, 36-40". All of the surround speaker stands that I see basically all look suited to much smaller bookshelf speakers. So if anyone is aware of stands that can hold a Heresy sturdily and around 36-40" high, please let me know! Thanks! six

Wow, that is literally the exact one. The KHorn might be the P9000 and the Heresy the P2000, as the KHorn has a slight faded browse/silver. My Heresys look just like the P2000 one, all silver. Either would be great. I'll reach out tomorrow and ask on those, and yup, only need enough for the face of the 64. Thanks so much. Will update when I hear back.

Thanks Randy! Was hoping you'd respond. I'll reach out to them and see what they say, I recall someone posting a link to an exact part number to a site that had a picture and it was literally the exact 70th anniversary metal mesh grille cloth. Might have been Wendell, as from memory the site looks similar but could be wrong. As for the badge, wow those looks fantastic! Who knew! I will definitely reach out to him as well. Very much appreciated. I am indeed, Heresy III 70th. The RC64 III is a larger speaker than the Heresy III is, granted it's really a 2 way but uses a legit compression driver in that speaker unlike the lower RP models, it's far more similar to heritage compression drivers in design. At the moment the Heresy III keeps up perfectly fine now with my KHorns now and sounds excellent, but I'd imagine output capability wise the RC64 III certainly must be able to move a bit more air then a Heresy can? Both have similar frequency response/range capability as well. Room, source, amplification and other factors are also pretty key to sound as well. Have you specifically demoed an RC64 III against a Heresy III or just going off memory from different models in different listening environments? Or have you had an RC64 III yourself? Just curious. If the 64 III is a 5% reduction in performance I'd be okay with that as I think that would be largely be offset by center placement being closer to my screen (upgrade); I'd put my TV on top of it with rubber feet to protect the veneer. I just think gaining an additional surround in the process for movie watching is a clear cut improvement even if at best the 64III is a side-step in performance for my center. It would also be slightly recessed and horizontally even with my KHorns making off axis viewing better. My Heresy is about 1.5-2" forward of my KHorns and on the floor, but the tilt and time alignment in the pre-pro offsets that in the main listening position completely. If they are a clear downgrade in my system after at least 150-200 hours on them I will just sell it, not gonna keep something I don't like. Don't see the harm in trying.

Hi Guys, I have the opportunity to purchase a custom RC64-III from Klipsch made to order in matching Australian Walnut veneer for my KHorn and Heresy 70th speakers as an aesthetic match is extremely important for me equally as it is sonically for tone/timbre. The RC64 would be a nice step up from the Heresy as a center, and it has a compression driver a lot more like something out of the Heritage line so I anticipate it to work really well as the Heresy does between my KHorns for movie dialog and 3-ch music listening with the PWK mini box. Sadly, due to furniture/media cabinet setup a Heresy or RC64 is the biggest I can do for my center channel; otherwise I'd have gotten the La Scala II 70th or Cornwall 70ths when I had the chance to do so. I am going to pursue this "Plan B" option as adding an RC64 and moving my existing Heresy center to the back, and moving my center rear to the opposing corner would give me 5.2 and would at least still be an upgrade from wide dispersion mono surround to traditional stereo surrounds. Anyhow sadly Klipsch says via the excellent Heritage dealer I am dealing with and was recommended to that they are unable to get custom grilles for my custom order nor any custom badge, just the Aussie Walnut veneer. I was hoping to also have the 70th anniversary grilles on it, in addition to a custom script "RC64" badge or a "Klipsch" script one so they'd look like they are part of the set in my system. They said it would be the plain black grille as-is from China. I also asked (via my dealer) if they would be able to paint the orange woofers black as they'd see thru the grille and I don't care for those orange woofers at all and would be a bit of an eye sore when I do see them during certain lighting conditions. It would likely bug me a bit, at least during the day. I'm 90% of the way there being able to order this in a matching veneer. But was wondering if anyone here knows what is the exact 70th anniversary grille part number and from which supplier and/or if anyone knows if someone could make a custom emblem for me for this? I would happily pay a member here whatever the cost is or be recommended to someone that would do this kind of aftermarket custom work. Seems many here are extremely handy with carpentry and this type of thing. It would effectively be a 70th Anniversary Grille for an RC64 III speaker, and a fitting script "RC64" or "Klipsch" emblem would be great on the bottom just like the other 4 of my speakers. I didn't ask yet why they told my dealer black grilles would be a bad idea on an RC64 but seeing how many of you guys do all kinds of painting/restoration work, would be curious to know your thoughts. If the orange won't peak thru with a 70th grille I'd be okay with it I suppose, or if painting them would be possible, and if so do you know who would be up to a job like that? Any suggestions/recommendations would be great. I'm going to order them as the main part is the finish, so best to get them while I can and worry about finding an aftermarket solution to this to finish off the exact aesthetic match I want, and not a semi-match. Really appreciate the help in advance!!! Best, six

I agree with this whole heatedly. The La Scala is amazing speaker and echo the sentiments above, for that more extended low frequency response the addition of a sub and you are set. Ideally a sealed one since the horn loaded bass is snappy and quick.

Those are beautiful. Never heard of the Icon series. Wish Klipsch would at least consider offering black/grey woofer cones as an option; they look much more elegant and a bit less "bling" lol. GLWS!!

Ironically the one in my left speaker upper cabinet was dead on arrival lol. Totally dead. Something must have happened when they were shipped or during moving while they were in the boxes going to my new house where I set them up for the first time 3 years back. Dealer reached out to Hope and Klipsch dropped shipped me a new K77D within 3 days, perfect sonic match to the other one so no complaints. Both have a nice metal sticker on the back with the PWK logo and "K77-D" underneath it instead of the plain ones or the ones with the ink stamped markings. Likely just aesthetic but wonder if that's how they sorted out the "best ones" as you said.
