Has anyone auditioned or purchased these?
They are much larger than the underground Jubs so the WAF is low.
I currently have modified Khorns with 2" format wood horns and BMS drivers.
Follow Ups:
I have followed the new Jubilee since it was a prototype and I own original underground Jubilees but with prototype k403 horns. The new Jubilee blows away every horn system I have listened to and it is amazing. The bandwidth for a two way is staggering 18hz-20khz.. It is truly state-of-the-art. The HF uses the new great Celestion driver on a K402. The selection driver has Roy Delgados phase plug. The LF utilized Roy Delgados Horn Loaded Sub technology. Then there is the DSP crossover with time delay. These things sound so clean and authoritative. Roy Delgado has been slowly incorporating and expanding on PWK's work from their conversations and has done him proud. BTW even PWK thought the first Jubilee was better than the Khorn. The new Jubilee is far better than the first Jubilee. This is one I recommend you put your own ears on and listen for yourself. I have had 6 listening sessions and two of those with my own music selections. The new Klipsch flagship is staggeringly good. I will be getting a pair in March.
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk

I have not heard them, but a friend of mine has. He was not that impressed. The Horn of a jublilee looks like the Scoop of a Front End Loader. They are 'Butt Ugly' IMHO.Both this friend and I have Khorn Bass Bins, Oris Orphean Horn System, Bi-Amped with Korneff 45 Amps and Hypex Bass Amps.... My friend claimed that the Jublilee could not hold a candle to our Khorn/Oris System.
You seem to have a similar system as ours, so I would not be that interested in the Jubilees... I think the Khorn Provides Superb Bass. I'm not familiar with your Horns, But that may be the only thing that may need improving.
What area do you feel your speakers are lacking, if that is why you are interested the Jubilees?

My Khorns currently have Volti's wood horns with the BMS 4592mid 16ohm drivers, tweeter is a JBL 2404. Previously, i had the Martinelli Horns using the original drivers. I had Alks extreme slope crossovers and then later built the crossovers John Warren designed which I like and is closer to the AK networks. I think what I'm hearing from the Jubilee's is the time alignment of the drivers. I started experimenting last week with REW and a Xilica XD4080 DSP bi-amping the speakers, I got the woofer to mid time aligned but need to set the tweeter on top of the speaker about 17" back to time align or tri-amp the speakers.
I did hear an improvement and also used the PEQs to get rid of some of the peaks from the bass cabinet and horn section.
Here's a clip of REW spectogram data with a just my passive. You can see the time alignment issues as well as the bass hump. Some of that bass hump is the tube amp (too much cathode cap).
Were the Volti's time aligned when you got them? I had thought that they were pretty much 'plug and play'. Or if you modified them, what were you trying to achieve?
No, none of the horns would be time aligned with the bass cabinet including the original horn Paul Klipsch designed. I think its a little more complicated than that (getting a time aligned horn and ideal dispersion).
I think that is what I heard in the Jubilee's not to mention the bass(2-12") was a little quicker than the 15" driver in the Khorns. I could live with the bass if I could get the top end to match the Jubilee's.
Well, I can certainly recommend the Oris Orphean horns. They also use a BMS driver with a concentric tweeter. So the tweeter and Mid are perfectly time aligned. See link.....
They sound awesome with my Khorn Bass Bins. Certainly a lot cheaper than jubilee. Why don't you email Bert at Oris and run some of your questions by him They also have a forum that you could pose some of these questions. Bert is really into measurements of systems and I'm sure he like to see yours. I have had my Oris Horns about 8 years now and I don't even think about changing them.

Not aware of a Oris with compression drivers, just the 150 which i wouldnt be interested
Here you go, and it is what I have.

I'd love to hear those horns but judging by your fish signature you are far north of me. I have owned my khorns since 1985, paid $1600 new back then. Purchased upgrades from Alk in 2005 including the Martinelli wood horns. I came across a used pair Volti horns and BMS 4592 mid drivers last year for the final upgrade to 2" compression drivers. I also removed the Alk extreme slope xovers and inserted a DIY pair of John Warrens xovers which are very good. Then i heard the Jubilee's recently and was shocked over the improvements, mostly in the timing. Doe's Oris have any plots of the setup with those crossovers? Are you using those crossovers as well or electrinic? Have you heard or compared to Volti audios horns with BMS drivers?
Funny, my fish signature is a Bonefish and the only place they are found in the continental U.S. is Florida. It's a Saltwater fish that likes warm water.I use the complete Oris Orphean System, which includes the 'M5' Passive crossovers for the Mid range and Tweeter both contained in one BMS Driver. I use an Active crossover for the Khorn Bass Bin and Horn, that is built into the Hypex Bass Amps.
I have never heard Volti, but am very much aware of the history of Volti... I remember when Greg of Volti got onto the Klipsch forum.. He started refinishing Khorns... He was mostly a woodworker back in those days and did a great job refurbishing cabinets.
What I would do if I were you, is get onto the Oris Forum and they will provide you with a lot of answers to your questions and provide you with a lot of plots of the Orphean System... If you asked on the forum if anyone had an Orphean System in Florida that they would be willing to audition, I'm betting you would have a good chance of getting to hear them.. The forum is : http://forum.bd-design.nl/
You'll have to register and get approved to post on the forum. The forum is actively monitored by the Owner of Oris Bert Doppenberg - He will most likely respond to all your questions.... they are located in the Netherlands.

Just got a plot sent to me from Bert.
They look pretty darn good on paper, i'll join the forum. I really don't want to go down another rabbit hole without hearing them.
Lol, I don't see much of those fish up in N. Fla but I've been an offshore guy all my life... It does resemble some cold water fish I've seen. You must of vacationed the keys in the backwaters. I'm addicted to a 50wide ripping out line...-
See you in the oris forum

Yes, Bonefish don't swim much north than Ft. Lauderdale... I spent winters in South Florida before it got too crowded... And during Covid... Spent 2021-2022 in downtown Miami and the keys and fished Bonefish in Biscayne Bay... Also fish tarpon in the shallows in North Florida, Everglades and the Keys. I have hooked a few big ones 150 lb.s to over 200 lbs. on my fly rod. The below picture was a Tarpon my friend got just south of Tallahassee in the shallows this past May.I had Altec Horns on top of my Khorns for about 5 years, but the Orpheans were much, much better... I don't think about speakers anymore.
Should be someone in South Florida with a pair of Orphean Horns running...If you're ever in Minneapolis Area, I will give you an Audition... Plane tickets are fairly cheap , considering the cost of high end Audio.

I have family in Buffalo but that's another 14 hrs to Minn. but I could always catch a puddle jumper. We get those tarpon up here in late spring and fall, fun to catch. But catching a Cobia on a knuckle buster is equally exciting.
I went 20 yrs without thinking about my Khorns until the forums came along.
Retiring next year so going to build a few more tube amps.
Yes, in this day and age you don't want to think about driving to Minnesota.... I did it in May -- Tallahassee to Minneapolis, But I'm retired and I helped my friend get his vehicle back to Minneapolis. And we decided to go Tarpon Fishing in the Florida Panhandle. So the drive was a last minute idea and I extended my Trip. He spends the winter at his place on the gulf coast in Mississippi and drives down every fall.... I usually drive down with him and Fish in Louisiana for a week and fly home. BTW- Cobia may be my finest eating fish.. Never caught one, but I've casted at a few.
Where in Florida do you live.... I've lived in Jacksonville, Ocala and Tallahassee and Spent Winters in Amelia Island, Cape Coral, Naples, Miami and Islamorada... I winter Internationally now.
I live in Jacksonville near the Mayo Clinic.
Boat is in the back yard on a lift, ready to go at any time.
We have snapper opening up this weekend. Right now, Cobia are on the wrecks and big shark. We have a lot of fishing pressure up here now so I go out 50-60 miles to fish these days.
I lived just off the St. Johns river and Blanding Blvd back in 72-73. I was in the Navy and Stationed at Cecil Field.
edit truncated my entire reply...

for a while I was on the 45 triode train as Dr Edgar - a friend of mine - was a big fan.
talking to Jeff guess what the secret to his amps was - he told me first hand : }
I've exchanged e-mails with Jeff quite a few times... None of his info was proprietary as he told me. Gave me all the schematics... He probably told me his 'secret', but nothing stood out to me, except the simplicity. What was the 'Secret' you got from him.
he said the secret of his 45 amps was that he used some kind of special chokes in his design.
he also recommended that I use a mercury vapor rectifier - that sounded a little scary - does your amp use mercury vapor ???
Kevin,
I'm forwarding a copy of what I sent to someone else recently-
That 45 amp was a take off on Eric Barbour's Single Ended Glory for under $100. I attached that schematic. You can download and enlarge. I never bothered with a written schematic of my own, the changes I made were all in my head. You could build the amp exactly as shown, PP transformers and all, and it will sound great. My first build was a mono version very similar to this one, even using the Sansui/Hashimoto outputs, just to see what might be there. I was totally taken in. Don't forget Eric was using junk box parts to build a great sounding amp. Genius.
The changes I would make as a final build to get the full 2 watts, not in any particular order:
use a Hammond 372FX power transformer (a nice transformer, better than 200 series)
use a 5u4 (octal) or 5Z3 (4 pin) rectifier with 20uf/500V electrolytic input cap and 20K 12W load resistor at B+ take off
use separate filament transformers for the 45's with 100 ohm 2W hum balance pots
use 1500 ohm -5W or better- 45 cathode resistors (if separated, above) with say 30uf-100uf / 100V bypass caps
use a pair of true SE 5K outputs from Electraprint- or your maker
use a pair of 50-50 uf/500V dual section electrolytics after the choke pairs
the Heath W series 46-12 (#?) chokes look nice refinished, seems to me they were ~10H, 150 ohm?
use min 2W 6SN7 plate load resistors
suggest using coupling caps to be 0.22uf (not 2.0), 400V or better, try Mundorf silver Foil in Oil
I would personally skip the mylar bypasses across the electrolytics
seems to me I used a 50 or 100uf/16V electrolytic for the 6SN7 bypass cap
It all fits nicely on a 10 x 17 chassis- photo attached. Aluminum.
You're looking for 275 plate volts for the 45 (plate to cathode), 56 volts dropping across the 45 cathode resistor, about 160 plate volts at 6SN7. You will need approx a 335V supply off the rectifier to get to these voltages. Using any other rectifier choices than those I mentioned may/will necessitate the use of a different power transformer rating.
Other notes: I did tidy up the 6SN7 and 45 filament supply voltages with 5W cement dropping resistors to put them "on the money". The amp was buss grounded to a power transformer mounting bolt. Also, the amp was dual switched to allow for preheating the 45's before B+ voltage could be applied- the B+ switch will do nothing without the 45 preheat switch being on. Don't be tempted to use high capacitance values.
The amp was built to run USA old stock 45's. If using overseas versions you would want to consider their specifications.
It's a power amp and will want a preamp ahead no matter that it could be driven directly from some sources. Seems to me the input sensitivity was around 2.6vac .. not sure now. But more than 2.5 and less than 3.
Be safe. High voltages can be lethal.
Hope this helps, feel free to share, Eric did!
Jeff
Bet it would sound excellent on my current 111 dB sensitive horns..
On box speakers, even with decent sensitivity, bombastic music was not quite there..
I'm sure the Korneff 45s would have worked great on your horns. My Oris Horns are 115db and the 45 amps have more than enough power. Especially since I Bi-Amp and drive the Bass bins with 500 Watt Class 'D' Amps.
