Palladium crossover networks...

I sure would love to see some. I am dying to know if they use higher quality parts than the reference and heritage lines. :)

Nets on the test bench.
Wow!! Those are very impressive! Only thing I'd change is using some nice Mills resistors, as the ceramic ones sound harsh and grainy. Edited by ninjai18

While not quite wrong, it's interesting and typical from the customer's aspect that we often look at the components used and forget what's involved to create a product...

 

That said, quite often it's the not the components' value/cost that play the major role, but the Non Recoverable Engineering (NRE) cost to create/invent a mechnical, electronic and production design are THE big contributors to the overall cost. Unless deep pockets, due this high NRE, most often companies doesn't undertake such a project !!!

 

Some highlights of Klipsch Palladium as below:

    - Project Goal: "No time and cost limit" objective to achieve the highest Klipsch standards set forth for Palladiums

    - Engineering and Design: Teams from three continents - in addition to the US engineering team, Klipsch partnered with

                                               BMW Group DesignworksUSA with BMW design studio to break the "boxy shell" and

                                               British theoretical physicists and manufacturing/production specialist from China

   - Echo friendly - exotic zebra-grain Linia veneer with a mulit-layer 1" or thicker "boat-tail" enclosure

   - Aluminum base and boat end on P-39Fs, with two length-sets of spikes and floor protecting discs

   - Unique carbon-infused, thermoset composite dual-horn configuration

          - Tweeter: proprietary tweeter design, combining a chambered phase plug and Tractrix® Horn for extended high-frequency response

          - Midrage: 90º by 60º acoustically dampened Tractrix Horn is coupled to the midrange driver

   - Crossovers: High quality electronic parts designed and tuned to get smooth transition from driver to driver i.e. speaker to speaker

   - Each pair has matched set of 5 speakers for Left and Right Speakers

          - If I remember correctly then each pair include a certificate with audio curve specification

 

If you add up all of the above, for the manufacturer to be profitable for a given product, require to sell enough quantity of speakers.

I think this goes well beyond speakers. I have people who try to argue about the dumbest things in regards to my utility trailers. Nearly always they have no idea what they are talking about. They know just enough to know some of the lingo and try to critique the technical aspects of building them. It is always a pointless waste of time and I've gotten to the point where I am happy to point this out. My worst customers are amateur welders, they will try to critique the welds before they even see a good picture much less see anything in person. I guess it makes them feel smart when they can ask technical questions in a "gotcha" kind of way but it is super annoying and pointless. They're trying to point out supposedly obvious product flaws and lecture guys who have been doing this for decades, it makes absolutely no sense. I suspect some of these speaker critique sessions are just about as useful.

It's a very vibrant, knowledgeble, mostly polite and passoinate community. Fortunately, I don't see fall-outs as fellow Klipschers discuss, learn and understand the points made. I love Klipsch and Klipschers...

While I'm sure that can be very frustrating, I can't say I agree that it's the same thing when critiquing the crossover components on Klipsch speakers. Anyone who has changed out the ceramic resistor with a Mills resistor can tell you just how immediate and striking the improvement is. I have done this upgrade myself - and read about many others who have - everyone who has heard my speakers before doing the upgrade says they sound much better after the upgrade.

No offense, but per Klipsch rep it's "Subjective"... I had a long discussions on this topic with Klipsch rep... Needless to say, either he didn't understand or didn't digest the issue at hand.

Quote (reply from Klipsch Representative):

Thank you for your being a long-time, multiple model, Klipsch brand owner and for reaching out to our Product Support group. Each product line and specific model would be engineered and designed to meet or exceed performance standards set by our engineering and design group, within the parameters of the marketing group* for that particular model and price-point.

Sorry, we do not recommend, suggest, or support any alteration/modification of any model from that which it would have been engineered and designed. The Klipsch Forum would be a free-form of expression (with reasonable limits as defined in the Forum terms) and we do not condone or support any product modification or DYI projects. While we do appreciate your desire to make modifications, and understand that sound and the perception of sound will always be very subjective and personal, we cannot support any modifications as they would be purely experimental.

It would be unfair to compare any other Klipsch model to the Palladium line as in 2007, the engineering group was for the most part, given a blank sheet of paper with no cost limitations (*even free from marketing persuasion), to create a brand new, three-way design from the ground up- thus the Palladium line was created.

The Reference product line was created in1999 and several generations of refinements have occurred with the latest refinements occurring in the fifth generation MK II models back in 2010 (there are no current intentions for changing the RF-7 II that we are aware of). The newest Reference Premiere line has just been released with the model RP-280F being the largest in this new line of models. http://www.klipsch.com/rp-280f.

Hope this helps offer some insight. Sorry we are not able to make any modification suggestions.

Which is proof they are simply not listening to what customers want. I would pit my upgraded RF-3II's against stock RF-3II's ANY day of the week, I wouldn't be afraid of any test or any listener they could throw at them. I 100% guarantee you my upgraded XO's would win out every damn time. This is all PR nonsense and nice way of telling us they don't care what we want. It's sad because I have always supported them and love the products they make, and it pisses me off that some people think it's totally "unreasonable" to request that they make improvements to parts they traditionally ignore.

I would not go that far.  Yes a bit of PR but that is what he/she is paid to do.

 

I would just understand that maybe the Klipsch rep/engineer was just pointing out that "altering" current or former generation Klipsch speakers may void the 5 year mfr's warranty.  I am sure they really don't care what "improvements" are made if warranty is not intact anymore.

 

Just my guess.

man we get it. But why cloud the forum complaining about something you are never going to change? What's next? Paying taxes? I mean come on. Klipsch isn't gonna start changing manufacturing to swap out s couple resistors to make us forum people (let's fall is the 1 %'ers) happy. They just aren't. Live with it. Enjoy your modded rf-3's. One day maybe you'll stumble upon a deal on some palladiums and you can mod them to see if they sound crappy stock as you describe them as they must sound that way because of some tiny tiny little ceramic resistors.

Side by side: Mills ceramic resistors vs. "regular" ceramic resistors used in the majority of Klipsch networks.

 

They are both wire-wound, and both have ceramic cores. Both are non-inductive up into the 100s of kHz range (I've personally tested). Tolerance is 1% vs. 2%. 

 

Top of the range Mundorf Supreme resistors clocking in at $15-$20 each are ceramic core, wire-wound, 2% tolerance and non-inductive.

 

The biggest thing that changes between resistors is power dissipation. The tiny ones used in the smallest bookshelf speakers are 5W, while the ones used in Palladium are 20W or 25W. They are of the same type as the Mundorfs listed above. Mills resistors are 12W, and the Mundorf Supreme are 20W.

 

As a resistor heats up, it creates more and more of what's called Johnson noise, which is caused by thermal variations. The way to lessen this is to have greater heat dissipation, hence, the use of "high power" resistors in circuits where while you'll never cook the resistor, you want as little noise as possible. Palladium took this approach.

 

By design, all that a crossover component can do is be less detrimental than any other. It cannot improve signal fidelity. Resistors, by virtue of being the most linear of all passive components, have the least effect by far. Inductors are absolutely the most carefully selected ones, yet get the least amount of attention. Changing an inductor of equivalent value but different DCR can quite literally ruin your crossover network and thus speaker performance. All Palladium inductors are air-core and were chosen for a reason. The ones in the P37, 38 and 39 low pass sections are about the diameter of a Nalgene and could double as 1kg bracelets. :P

 

Just a touch of light on the selection of components in crossover networks. :)

Because one voice can make a difference by bringing a lack of quality issue to light. If everyone thought like you, nothing in the world would ever change or improve. You don't like me pointing it out? Boohoo. You remind me of the Microsoft fanboys that defended Microsoft for their policies of disabling used games and and having an online 24 hour check in. I'm sure glad a lot of "nobody's", unlike you, actually spoke up and said something and got it changed. There is NOTHING wrong with a single "nobody" bringing an issue up and talking about it. Lay the **** off of harassing me for saying something.

Say what you will, but you cannot deny results. Every person who heard my speakers before the mod agrees that they sound far far superior after the mod, for minimal cost to boot. People would not be paying people like Bob, Al and Dean to do mods to their crossovers if it only made negligible improvements. It's simply factually incorrect to say the difference is minimal, it is not. People keep saying "they chose them for a design reason" - as though they couldn't possibly choose lower quality parts - yet every person that upgrades their crossovers loves the improvement. It truly amazes me that I am being pushed aside and scoffed at for having the "audacity" to say they could use improvement. I never even attacked Klipsch, I have stated multiple times on this forum that they are my favorite speakers and I love them as a company. Amazing that being a loyal a fan isn't good enough, I suppose "zealot" would be preferred.

and yet hear you go again disagreeing with someone who im pretty sure is a Klipsch employee. You asked for an answer. The guy gave you one. Yet it's not good enough.

Calling me a fanboy doesn't hurt my feelings. I like Klipsch speakers and other companies as well. Klipsch suits my ear for what I can afford. If you hadn't noticed I own their cinema line and the palladiums. Is that fanboy to do that? Lol sure why not. Guess what? I bet you any amount of money you want that all of them sound better than your modded rf-3ii's. Even with their "crappy" crossovers. Im not the only one that feels your whining a bit either. So keep boohoo'ing as you call it. :)

Dave is about the smartest speaker engineer most of us will have the chance to talk to.

I am over this.

 

You guys need to lay off.

 

Ninjai18, maybe it's in your delivery and not the content that gets a few people bent.

 

Let's just keep the peace :wub:  even with differing opinions.

My good man, I think you misunderstand. Firstly, I hope you realized that I am a loudspeaker engineer for Klipsch who makes said "design decisions".

 

No engineer would ever spec a part of low or poor quality. The crossover is the heart of the speaker, and easily the most important part. Minor changes here and there have massive ramifications. To "upgrade" your speakers with Mills resistors and Auricaps of equivalent value is your prerogative. We will never endorse such a modification, however.

 

To "upgrade" your speakers by changing values means that it is no longer design intent and you've tailored the sound of a Klipsch speaker to something you happen to prefer. That's perfectly fine since everyone has their own taste. This does not make it a better Klipsch speaker. It makes it a speaker using Klipsch parts that you've modded. Either way, that's your call.

 

However, to state that the RF7 with its stock resistors is horribly grainy sound and simply by putting in a different ceramic resistor you can create audio nirvana implies that the people who designed your speaker in the first place are clueless. If the difference is so stark, then we clearly don't know what we're doing otherwise we would have done it in the first place. Alternatively, it could mean that we do know what we're doing, but we knowingly neutered the flagship Reference speaker. Consider that for a moment.

 

You are free to mod, purchase mods and post mods on here at your heart's content. Us engineers are fully aware of the science behind capacitors, inductors and resistors. We don't chose parts that compromise the drivers and cabinets we spend so much time and effort designing. If you hear a large difference using a different resistor, then that's fantastic that you're enjoying your speaker even more. If you like them stock, then that's just as fantastic.

 

Do not assume, however, that we're putting cheap, low quality parts in products that we're proud of. More to the point, do not imply that had we only done what is obvious, that we'd have a far superior product. Trust me, we've got it under control. :)

two weeks ago he couldn't read capacitor values, schematics, or solder to save your (pcb's) life. Now he's the resident expert on crossover mods, the electrical properties of inductors, and has made it his personal mission to change Klipsch's business model? did i miss something?

I once saw a guy have this same kind of conversation in regards to his silver banana plugs and some $250 wires. The rest of his system cost $200, total. So many people "want" to hear a huge difference after a mod that I have a hard time chalking it up to anything but a placebo on many of them.

*frantically searching to make sure it's not me you're talking about*  :ph34r:

 

btw, this is a very relevant concern for me. Dean reworked my cornwall B2 networks about a year ago using the principle of battery biasing, basic parts-express caps, and the original 32yr old "everything else". They sound great and were indeed an improvement over the original aging networks.

 

i should be receiving my all-new B2's from Dean soon.. Jupiter flat stack capacitors, wax impregnated 2.5mH coils and  autotransformers (with a beefier chassis than stock), and everything else he does to make it a high quality build. he's worried it won't sound any better than what I've got in there already -- and I have to fight the impossible urge of allowing my financial bias and placebo to impact my listening impressions. I'm certain they won't sound bad, but will they sound miraculously better?

 

i don't know, but you certainly won't see them up for sale any time soon. :P
