- Frequency range from 18Hz to 20kHz at what level? From the spec sheet found at the bottom of the product page (https://www.klipsch.com/products/jubilee-floorstanding-speaker) SPECIFICATIONS FREQUENCY RESPONSE (+/- 3 dB) 18Hz – 20kHz SENSITIVITY1 HF normalized to LF - 105dB/1m POWER HANDLING (CONT/PEAK) LF - 300W / 1200W HF - 100W / 400W MAXIMUM SPL 125 dB/1m (Using DSP) NOMINAL IMPEDANCE LF - 8 ohms, minimum 3.8 ohms HF - 16 ohms, miminum 8 ohms CROSSOVER FREQUENCY 340 Hz HIGH FREQUENCY DRIVER K-693 5” Titanium Diaphragm Compression Driver LOW FREQUENCY DRIVER K-281 12” Fiber-Composite cone woofer ENCLOSURE MATERIAL MDF/Plywood INPUTS 5 way binding post HEIGHT 69” (175.26 cm) WIDTH 50” (127 cm) DEPTH 30” (76.2 cm) FINISH Black Ash, American Walnut - How does a 5" compression driver reproduce 20kHz, pushing a fairly large volume of air in such a horn? The Celestion Axi2050 is not your usual compression driver. The diaphragm is not a simple dome. It's a low mass, flat, annular, embossed ring clamped at the inner and outer edge and driven by a voice coil in the middle of the ring. (https://celestion.com/product/axi2050/) - The horn, according to theory, is 3.5 octaves wider in the range of reproducible frequencies. And here we have almost 6 octaves, from 340 to 20,000Hz. The K-402 horn can control very low, down to about 200 Hz. That, combined with a wide dispersion phase plug (aka throat lens) gives it very wide bandwidth performance.

On the question of the finish on the Forte in question, it's a lacquer finish. Oiled finishes have not been available as a standard finish option for Klipsch speakers in decades. So WATCO Rejuvenating Oil would not be appropriate for these.

Yes, the Belle upon which I used the Trade Secret Scratch Remover (the one for light wood) was a lacquer finish. I was very pleased with the results. Just be aware that it will slightly darken and slightly yellow the finish. Since the lacquer on my walnut Belle was already quite yellowed from age, it wasn't an issue for me. Using it sure beat refinishing the speaker. Maybe test a small patch on the veneer on the bottom under the riser to see if you like the results. You can see a before and after picture of the top panel here:

The problem is that the Jubilee bass bin is not a rectangle. The stairs would have to be over 50 inches wide to be able to place the back or front of the bass bin against the stair climber. A stair climbing hand truck worked well for getting my P-39F into my basement. However, it would not have worked if I tried that with my Jubilee LF since it can't be loaded on the truck sideways. Luckily, I kept my Jubilee on the first floor.

Pictures, location?

I was hoping that when these went up for sale that it would be at a realistic price. I had a thought that we might organize a group purchase and donate them to the Klipsch Museum of Audio History. That's where I feel they belong. It's certainly out of the question at this price.

The TV itself cannot run passive speakers like the Quartet. You will need a receiver to power the speakers. To get the TV sound to the receiver, there are a few options depending on the features of the TV and receiver. Most modern TVs and receivers will support an HDMI connection with Audio Return Channel (ARC) support. If the receiver is older but still has optical digital inputs, many TVs still have an optical digital output that can be hooked up that way. For very old receivers with only analog RCA inputs (like the one my parents have), I used one of these digital to analog converter boxes (https://smile.amazon.com/gp/product/B005K2TXMO/). It worked well for what it is.

Pretty sure it's a $4000 difference per pair. The standard edition is $36,000 per pair. Both Upscale Audio and HiFi Heaven show the 75th Anniversary edition price online as $40,000 per pair ($19,999 each).

I believe it a $4000 difference per pair between the standard and anniversary editions.

Agreed. Also, there were some modifications that were once acceptable here, like the various forms of JubScala with a K-402 or K-510 replacing the stock mid/high components. I believe Roy even provided DSP settings for a few of those combinations. My modified Belle is really conceptually no different than those except for the fact that I used a non-Klipsch horn. (The compression driver is the same one that's in the new Jubilee.) Perhaps the use of that horn was enough to disqualify it from acceptability. Who knows. So, the rules have changed and I'm fine with that. It's Klipsch's sandbox. I'll risk flogging an expired equine here and restate, get those rules in the community guidelines. I think I've said enough on this topic.

Based on what Travis and Roy say in that thread, my post about my modified Belle likely should not have been deleted. The modification was made for my personal use only. I have nothing to peddle. I also didn't call it an "upgrade". I stated that I made the modification to make it a closer timbre matched center to the Jubilee. So, to me the boundaries still aren't clear. Also, I should not have to find a particular discussion thread to know about them. They need to be in the community guidelines.

I guess I should have been clearer in my first sentence there. I just wish the NEW rules were spelled out clearly. The guidelines seem pretty clear about courteous behavior, etc. I meant we need the rules about topic boundaries stated clearly. The "builder" (i.e. the person who put the modified speaker together) was me and I don't sell anything. The Forum member who built the replacement wood parts did it as a courtesy for me personally. As far as I know, he only builds DIY speakers for his own use. Of the two third-party parts that I mentioned, one is not a direct competitor to Klipsch as far as I can tell. Admittedly, I haven't looked at every page of their website, but it's certainly not obvious that it's a competitor. The other is actually an OEM supplier of a part for the Jubilee. So, the only thing I can conclude from this is that modifications can no longer be discussed here. If that is the case, spell that out in the community guidelines instead of enforcing an unstated rule.

I just wish the rules were spelled out clearly. There has obviously been a change in policy as people have discussed modifications here for years, but I don't see that change spelled out in the community guidelines yet. I would not have posted about my modified speaker if the rules had been clearly stated. This is Klipsch's forum, and they can change the rules when they see fit. Just don't leave us guessing about what the new rules are.

Not sure how much I should say here. I will say that the center exceeded my expectations. There was no drama on the thread at all. I think it was deleted simply because it was a mod post. I though the new rules were no mentioning direct competitors. Klipsch doesn't sell horns or compression drivers to consumers except as replacement parts. I guess there is no longer tolerance for mods of any kind.

The room is too narrow for that. It would look like a wall of Jubs shoved together. 🙂

The British classical label Nimbus Records released Ambisonic recordings in the '80s.

"We gotta go to the big room for this." 😁

He also misstated the crossover point as 600 Hz, when it is in fact 340 Hz.

I was into them when they were the best home video format available. I had a good-sized collection. I still have working players in two systems, though they don't get much of any use. I still have, at best guess, a few dozen LaserDiscs that I can't part with for sentimental reasons. 🙂 I even have the Klipsch 101 LaserDisc and the companion training booklet. I keep the jacket on display.

I know. I was just making people aware that several other Jubilee systems are posted there if they wanted to go look.

You should not be afraid of exploring the used market. OEM or aftermarket parts are available for used Heritage and Legend series speaker. Replacing bad diaphragms/drivers is not that hard once you get up the nerve to do it. Most of my horde of Klipsch speakers were purchased used. The only time I ever replaced diaphragms in all those used speakers was when I wanted to replace some of the stock tweeter diaphragms in my KLF-20/30 and a few others with Crites titanium ones to get better top end extension.

I guess RF-7 III or Forte would be the similar value, market niche speakers. However, if you like the sound of the 3-way Legend series speakers and want current product, then you should get something from the Heritage line like Forte or Cornwall. Heritage speakers are the only current ones that cross over from horns to cones at a similarly low frequency to 3-way Legend series, ensuring similar mid-range clarity.

You mean like this one that I bought on eBay a long while ago and had in another system for years? 😁 Before you ask, I don't want to sell it. 🙂
