Hope you enjoy it!

Thanks for watching!

I did the GR research kit for the original ones and it made a really awesome improvement especially in soundstage and soundstage depth

I did there kit on a gen 1 and I kept the sonicap and swapped the other for a mundorf. Sounds pretty good to me compared to stock. Seems to hold together more with aretha franklin’s vocals. I power w the 6sq7 amp and it seems to have just enough power even w the decreased efficiency. I usually run it wide open though

Which is why I didn't want to do that Xover mod to these speakers. I'm also 100% sure in a different room or setup differently, these speakers wouldn't work.

Yep.

Exactly.

the rp600m ii 3d effect is very apparent, the singer looks like a giant to me 😅

One thing you can do when building a tube amp is use output transformers with a higher Z than the minimum required. You give up a few % of power, but now have an amp capable of driving a wider variety of speakers!

I have a pair of 600ms along with Klipsch Heritage La Scala and Chorus 2. I used an OSHA calibrated meter with 1 watt at 1K hz at 3’on all 3. The Heritage speaker where dead on listed specs. The 600M measured 90.5 db. I was told Klipsch now uses a different method using a range of frequencies that is more accurate. But if everyone doesn’t use the same systems it’s pretty much irrelevant for comparison. I don’t like what they are doing either. That being said I still like the 600M

@@SkunkieDesignsElectronics Sure, you could also add some global feedback from the secondary side of the output transformers back to the input, that would probably do more to lower the output impedance, but still you'll likely have more than 1 ohm output impedance, and with these speakers going from below 4 ohm in the low frequencies to 15+ ohm in the high frequencies (ignoring the extreme peaks) you'd still get 20% variation in the frequency response, as in low frequencies will be attenuated compared to high frequencies. So they'll end up sounding thin with little bass. Cheers, Jake

Finally subscribed. I think a lot of people are split between the old and new version of this speaker. Personally I haven't heard either one, but I am a fan of almost all of their Heritage line of speakers. Other Klipsch speakers I've heard all sounded bright to me. Of course the Heritage line is way more expensive so may be out of range for a lot of people.

Speakers are so dependent on things like room size etc. People tell me I need a pair of La Scala, I'm pretty sure they aren't gonna work in my tiny house and I'd have to remove 1/2 the furniture to even have space for them. Some folks can't imagine everyone doesn't live in a 5000+ sq ft house. with a 1000 sq ft living room.

@@SkunkieDesignsElectronics Who needs furniture ....😆 Seriously , and as nice as La Scalas are , they are not everyone`s taste either , and not everyone can accommodate them , as you say.

the rp600m ii sounded very warm to me, i was surprised with all the metal dome and tweeter they would sound shrill, but no the opposite, the midrange is thick and the singer looks like a giant 😅

Got these for the holidays, the midrange/vocal is kinda pushed forward and the stereo imaging is very big, clarity is good but kinda lack that sense of space/depth from the singer to the stage/recording room

I honestly have not found any "tone controls" that don't somehow harm the sound in some other way. It's why I work to shape the tone curve to my room with specific tubes, speakers etc. But yeah, subjective reviews are 100% personal taste, it's why I also like to provide measurements!

@@SkunkieDesignsElectronics I agree with you Skunkie. Measurements are critical, and they are a great way to objectively ‘see’ what a speaker or piece of equipment is doing, especially compared with one another. But ultimately you like what you like, and it doesn’t matter what the measurements say. Case in point, new RP600M vs old, new measures better, but you like the old. Same thing happened with your review of the little Decware Zen. Didn’t measure well, THD too high for you, but others love it. Some people like chocolate some people like vanilla. All that being said, I do think measurements are extremely important, but in the end it’s ultimately personal preference that rules the day. Measurements get you in the ball Park, but then it comes down to individual ears, and listening rooms. That’s why tone controls are required (put in a defeat switch for the purists) A perfectly flat response might not work for my old ears, or my poor listening room that my wife won’t let me treat. So those tone controls come in handy for us old audiophiles that just want the music to sound good. I know you know what I’m talking about, you’re a self proclaimed bass head. Some songs might just need a little bump in that bass and that’s what the bass knob is for. Lol. 🤣 Thanks for commenting back to me. Always enjoy your videos. Hope you have a wonderful day, and many hours of enjoyable listening. Peace ✌️

I don't think they are going to change a lot after 40 hours.

@@SkunkieDesignsElectronics I don`t think they will either. You would never be happy with keeping them , I think.

but the 500m don't go as low

100% And I warn people that my high frequency hearing, like many older folks, is weak and what sounds great to me, might not to someone in their 20's. That said, what sounds good to a 30 year old reviewer, might sound flat and dull to someone who is 60+.

I might give a pair of those a try!

I haven't but a friend of mine has, it can work with an active crossover before the amp.

Thanks!

Superior Z, the big red ones.

Thanks for the info!

I'm an infant when it comes to speakers. I'm still trying to figure out what I'm doing wrong with the DIY3.1 kit lol.

I listen to vinyl :)

@@SkunkieDesignsElectronics Ah yeah then it's less easy to EQ the speaker tonality. I tried analog EQs in the past (I think it was a Yamaha Pro Audio thing) and the effect on sound quality wasn't pretty.

LOL and?

@@SkunkieDesignsElectronics December 2023 issue.

That doesn't change my opinion or what they sound like to me. I could easily just keep these RP-600M II but the older version is more enjoyable to listen to to me. I disagree with quite a few of the mainstream audiophile folks.

@@SkunkieDesignsElectronics I agree on that, I bought the "Speaker of the Year" a few years ago and couldn't return them fast enough.

@@SkunkieDesignsElectronics Thanks for keeping it real. Neither modeling Amps nor flattening curves doesn't create sound. That dip in the RPM600s' response has been overhyped and over-measured when there was so little data on whether it matters. I love specs like the next person, but it's just like in photography where I see a gazillion test shots of a brick wall with the latest gear but not a single photograph that shows how it actually matters.

Bingo! And which speaker or amp makes me tap my foot and smile is highly dependent on both my room and my ears, many of ours have aged and probably been subject to a lot of abuse! Add in the memories we have from listening to live music in various places and how that was EQ'd, our expectation of what "sounds right" is literally all over the place!

@@mddawson1. Wow that's dear mate! NO strayans are gunna buy these, they're just not that good! Who's making all the dag gum mark up on these then? What a ripoff you theiving bastards!

They have about 40 hours now before I boxed them up. I can't imagine they are gonna radically change from this.

Everything in this country ( Australia ) is horrendously overpriced. Everything.

@@hardystein114same in South Africa. We literally pay double what the Americans pay.

I think a lot depends on the room they are in. I've listened to them at a friends house in a larger room and wasn't impressed either.

This channel is focused on budget DIY. And honestly, I've listened to "better speakers" as told by other reviewers and for my taste, they didn't sound better. I have a pair of Klipsch Chorus speakers a viewer gave me, which many would say are better speakers, but in my small home those big speakers just don't work. If my 6BM8 amp can drive the speakers I have to the volume levels I like, then these are efficient enough.

@@SkunkieDesignsElectronics Fair enough. But to be as accurate as possible when you deal with Willsenten and Decware and stuff like that, it would be good to have speakers that are a step above the amps in quality.

Here here

​@@EskWIREDhuh?

@@dilbyjones yep.

The only mod to the speaker was changing the brand of one film cap with the same value cap. it didn't make an earth shattering difference (honestly not sure it really did much..) and the change wasn't measurable.

Aww :(

Yup, in pursuit of flat response measurements...

Of course it is, hence this was a subjective choice I made :)

@@SkunkieDesignsElectronicsThat’s what I really appreciate about your review. Well done.

Yeah, keep reading those forums...

I know the RP600M sounded nice out of the box and their character didn't change. I didn't need to play them for 60 hours before I liked them. Is there something that different about this version II that they sound bad out of the box and completely transform after 2 work weeks of hours of play time? If you think the PR600M speakers suck and I love them, you probably shouldn't take my advice on speakers, just saying :)

@SkunkieDesignsElectronics I don't take anyone's advice as gospel, I have been buying electronics/home audio equipment since the early 80's, right now we have a Marantz cd player and Marantz receiver, 12 guage svs brand speaker cables and audio quest interconnect cable
