In this weeks Tech Talk, Danny Richie from GR-Research walks us through part 1 of upgrading the Klipsch RP-600m's, taking them to a whole new level. +++ www.GR-Research.com Audiocircle: www.audiocircle.com/index.php...
I am so freaking excited to do this to mine!!! I love working on speakers. It's my hobby. I am happy to have someone teach me all of this through a series of videos. Now I can apply what I am learning to mine! Thanks!
I don't understand downvotes in a video like this! Someone goes to the trouble of explaining something in great detail and it gets downvotes? Keep up the great work! :)
The thumbs down are by flat earthers from the previous video who were triggered by "Flat Earthers" being used as to mean "Scientifically Ignorant Persons" Screw flat earthers anyways. They're all stupid ignorants.
I don't think it would be klipsch employee, the video is encouraging people to buy a Klipsch speaker and improve it for $205. Even with the ratings on this speaker, I wouldn't buy it, but now it is a DIY project. It interest me. I'm a quadriplegic who likes working with my hands in watchmaking, gunsmithing and electronics.
@Fat Rat Thanks, I have always heard that about Klipsch. Way back when, I don't think they called it "listener fatigue" in my circle but conveyed the same experience to me. I have a Ok 5 speaker system for the TV by Hsu. I want a 2 speaker system for my 13 y/o daughter and her having speaker fatigue after 2 hours sounds perfect. I have listening fatigue to any of her music after an hour. Having a project is a double winner. I have been thinking of building from scratch, this is a nice compromise. Thanks for your expertise and patience in explaining.
I'm glad to see you do this because I am doing a old pair of speakers that I have. I know I will learn things that I did not know and do things right. Thanks
Nice video on upgrading these. Just curious about a point that you made about cabinet resonances not being a part of the original signal. I agree but couldn’t you make a similar argument about the port output in a bass reflex speaker? Thanks!
The sand cast resistors are often not inductance compensated, so they can have quite a significant inductance value, which throws off the crossover and does have an audible effect. Higher end power resistors wind in both directions to cancel out most of the inductive effect of using wire wound resistors.
Hey Danny thanks for another great video. This videos series is really interesting. I really enjoy learning about parts cost. Man I love those parts that you are using. You really make it easy to follow along with what your explaining, without talking down to us viewers! Kind of surprised that the woofer has a stamped steel basket. No cross bracing either. Thanks for another awesome video Danny.
This is overall really great...inspiring me to try it at some point! Just one question, does the “no-res” application effect the internal volume in any appreciable manner? Wondering how that could effect the low frequency depth. Response would obviously improve, however?
@@thunderpoochValid point. Perhaps some account is taken of this with the values of the replacement parts? I'd like clarification, too. OTOH cabinet resonances are very damaging to sound quality. This could outweigh the effect on tuning.
Hi i'm a decent woodworker , would it make sense for me to craft some custom made boxes made out of a hardwood rather than the particle board stock box ? Other than looks would there be a difference in sound quality . I'd manufacture them exactly the same.
Maybe I missed something. Is there an upgrade kit or do I have to source the parts individually? Not clear where to find the parts for the upgrade, I looked at the GR research website and did not see it. If someone could point me in the direction of the upgrade parts I would be appreciative.
I got pumped by this and started the upgrades on one of my RP-600ms. I changed the binding post with tube connector pure copper and used some left over Dynamat for the cabinet dampening. The results: base is more tight and mids/highs feel more precise. I would attribute that to reducing the resonance in the cabinet. The binding post look more sleek now as well. For 60$ this was a great upgrade plus a fun project. Looking forward for the crossover upgrade video. :D
Thanks for posting your feedback Ismael. The Dynamat will tighten up that bass response a bit, but the more precise highs are a result of the tube connectors.
Great stuff. I would pay for this but i doubt that someone around here makes upgrades like this. However one question - Is the resonance of the cabinet not an intended thing? For the sound/bass to have some mass? Isn't the sound somewhat flat with The Nores?
Cabinet resonances are not intended. And when your box is buzzing it is masking the actual bass output. You never what your speaker to become instruments. You want them to be able to faithfully reproduce real instruments. And No Rez simply damps out those resonances leaving you with cleaner and tighter bass response.
So if let’s say I decide to upgrade the parts of the speakers crossover, can I just upgrade equivalent parts. Let’s say I send you a picture of the crossover and we can upgrade the parts or we still need to measure the speaker cos it will effect the sound?
I did not see a kit on your website for this. Am I not looking in the right place, or does it not exist? You referred to the cost a few times, so I was hoping it might be available for purchase. Your videos have me dying to try this!
Really would like to purchase a kit for a pair of these from u… there is no link to where I need to go to purchase this. Can you help me. Thank you Scotty
I have a two pairs of klipsch kg 5.5 they have two 10 inch woofers and a horn Tweeter in each cabinet. But I have them stacked because of space it's like 13bye 13 ft.and 9ft ceiling I like hard rock loud very music would like to replace crossovers for stacked proformace what would best for that ? Could you build it or is a bad idea?
Hi Danny. I hope the center channel comes in before you finish this series. Would adding some more bracing or hardwood strips be worth the effort? Adding some sort of damping material on the woofer(Sorbothane)?
New to the channel but this is pretty interesting stuff to me. When you say you've A/B tested is that blind subjective testing on top of the measurements?
@@dannyrichie9743 good to know. Personally, maybe my ears aren't that good but as soon as I test blind I sometimes struggle to reliably hear the differences I could when I was testing not blind so it's always a good sign for me to see subjective tests being done blind.
Simply brilliant content. I, like everyone else watching this I am sure, feel a little cheated by the industry (as sure Klipsch are one of many guilty of this). We chase better sound by changing and upgrading cables and yet all that time the weak link is the STEEL in the binding post assembly (which I am AMAZED, and infuriated, is used). What are we all doing?? This is a REAL eye-opener of a segment. Shame I am in the UK. Would send you my ProAc's to pimp, though I fear the quote will be more than the $209 for this little lot.
Absolutely great video, Danny. I can’t wait to see the rest of this upgrade. My only question is would it make sense adding something like dynamat to the metal frame of the speakers to further dampen it, or is the No-Rez enough when dealing with a speaker that small? I’d personally think to dampen the insides as much as possible would be the most advantageous. Thanks so much for another great vid, Danny. I love Tech Talk.
Great thought, and yes some thin strips of Dynamat on the back of the woofer frame would really help keep it from ringing. And yes that stuff can really make a difference.
Do you do these upgrades for others for a fee, or are you just showing us how to do them for ourselves? If you do them for a fee, can you provide your store name, contact info, etc.?
Hi Danny I will be buying this upgrade as soon as u have it avalable, I just recently got a pair of Polk LSIM 707 I think for the price they sound pretty good. Do u have an upgrade availabe for the LSIM 707 ? thx
You know Danny thats really cool but as I think the upgrade without doubt will be significant I'm thinking I'll even take it farther & build a new box out of baltic birch & while I'm at it I'll replace the woofer & then Why am I going to buy these in the first place when I can buy your new open baffle monitor kit, now thats a no brainer.
Hi Danny.. this was a great video and in time I imagine valuable for when these speakers drop in value in the used market worthy of upgrade or perhaps today based on the final audible results.. I'm wondering, based on the current market costs alone, cost of an RP-600M plus the upgrade kit ($400+$210=$610), what kit from your company (same relative size - ie bookshelf) is a better speaker when measured using subjective metrics (sound stage, imaging, clarity/resolution, base response, frequency response, dynamics, etc.)... or how does this upgrade compare to other similarly or higher priced speakers in the market? And are these good questions to be asking?
Good question. You could build our X-LS Encore kit (similar sized bookself speaker) with all upgrades for less money and blow way past these in every way. But it is a complete kit. You build it yourself including the cabinets.
Thank you so much for your information. I also am interested to hear if this can be done to the RP series center as I also use these as fronts and would like to have the center match.
I second that! I use these for music in stereo, but I have the RP-600M set as my fronts for my home theater. I have an RP-404C center working with them and RP-400 for surround. I would like for at the the center to be matched to the upgrade.
Nice mod! But, are all iron-core inductors really that bad? What about audio signal tranformers, MM phono cartriges, tube amp output transformers etc? They all use iron cores.
