Agree completely. Always impressed with Danny’s skills.

When I was out at a track doing some training yesterday (running 40 yard sprints this time) I sure didn't feel like I have been aging backwards. My times kind of sucked too.

@@dannyrichie9743 never stop. I ran my first half marathon in London at 59 with my daughter in 2 hours. Then a year later had my stroke. So do it while can. Run one for both of us!!

I seen experiment on mouses. Sport increases possible timelife.

Bla bla bla.

@@thomasschafer7268 don’t understand your comment. Show me better speaker upgrader, I’d love to learn more

I always find it amusing when someone post a comment like yours. You just spent all of your precious time in life watching some thing you think is ridiculous. What does that say about you?​@@thomasschafer7268

@@stephenyoud6125 the type that will waste 20 minutes on something they cant comprehend just to poo poo it in the comments. all you need to know. trolls even here....alas

This speaker was a beast when it was released in 1977. Other speakers back then were trash! I bought it used in 1990 and it was my first real hifi speaker.

​@wa2368 other speakers were not trash in the 70's😂😂😂😂

. Ya, I caught that too & I agree with you. These were high performance HiFi. I'll let it slip, lol, because GR's work is outstanding.

@@TriAmpHiFi What he did for these speakers is nothing short of amazing.

There were lots better from AR, Klipsch, Wharfedale, Quad, Infinity and even B&W. Pioneer was a low end hifi company that did appearance over function. Pioneer preferred to make money over engineering.

@@morlidor you won’t hear it over KZfaq

​@@stephenyoud6125 And I think people just send in one speaker for Danny to do his upgrades

I don't think there's any help for Bose products. Sorry. 😊

@@dextermorgan1 you could say the same for almost all the vintage speakers he gets

Currently using a pair of 301 series II. I've changed the front tweeters to a pair of old large Advent orange fried egg tweeters putting them in the same place with some angle brackets and wired in series with the back tweeters. I've also took out the old cross over and went with a simple first order at about 2600 hertz with a Solen 6.7 uF Cap. I did put a variable L- pad in the circuit and is stable at 9 olms the woofer has just a coil 0.5 mH so it's also first order. I put the L- pad in to bring the tweeters level down a few decibels as it was a bit brite for my taste. That was definitely an improvement. I think the bose tweeters at 2600 might be a comfortable low for them and a higher order cross over might be a benefit to lower the crossover frequency ( not much) and keeping the drivers from over lapping as much. So I would go for it because the original cross over was just a first order only on the tweeters. I had the fried eggs on hand so I used them....they are rather expensive at over a hundred bucks a pair. But I think the original tweeters okay. The biggest problem is that the tweeters play over the woofer . And the spring terminals are cheap. The original circuit on the tweeters is funky with a light bulb acting as a current limiter and a 8 olm resister all drivers and parts in series resulting in a 16 ohm tweeter circuit. I might try a second order cross over in the future. But at the very minimum put a coil on the woofer..It worked out great and I went first oder because it's what I had on hand. I think I would stick with 2600 hertz because the fs for the Bose tweeters is about 1300 hertz. Anyway going 2nd oder and using the original tweeters should be an improvement with some relatively inexpensive components will go a long way. Those tweeters have a high sensitivity so some attenuation will probably be necessary. And I did stuff the ports and have a subwoofer. There is a very small pair of speakers ( 4.5 inch mid base and 0.75 inch soft dome) sitting on top a piece of carpet and the pole pieces in a plane ( approximately) lined up with the Bose.wooofer . The small speakers are tilted in slightly and on a separate amplifier to control the relative volume. And the Bose tilted out slightly. The Bose are slightly below ear level and the small acoustic suspension speakers ( pretty high sensitivity and no deep bass , but excellentvocals) slightly above and sitting more to the middle depth. So I have a good sound stage. It's all stuff I had and made it work. Sounds good in my largish room in a finished basement. Last note I don't know what the power handling for those tweeters is, but I'm not listening to them at high volume either and I'm certain that the Bose will go away and open the circuit before the Advent tweeters and I do have a spare pair of Bose tweeters now kinda like a replaceable fuse.

You'll have to take the title up with my editor. He comes up with those and the thumbnails. Whatever grabs the most views...

aka internet click bait. i was born yesterday

​@@hom2fuAt least Danny told you the truth.

ADS L1290

@@jamestyrer907 Those ADS speakers you mention are nice (smaller) tower speakers too, but have you ever even SEEN the Infinity IRS-V speakers, especially in combination with their matching subwoofer towers? I mean, we're supposed to be talking about the ALL TIME KING of vintage speakers here, so they're definitely gonna be something that makes almost ANYONE go "WOW!" (or something even more explicit), whenever they first see and/or hear them! PS Audio in Colorado has a set of the infinity IRS-Vs in one of their demo listening rooms, and every time that Paul McGowan, the CEO of the company does a KZfaq video while standing next to them, I'm just blown away by their sheer size alone, as all four towers that make up the system, both of the front mains and both of the matching subwoofers, are all literally almost 8' tall, and the system weighs well over a TON! If I'm ever up in the Denver area I'm definitely going to be stopping by their manufacturing plant there and visiting long enough to get to hear a demo of those speakers, along with their own new models for comparison!

You obviously have not watched too many of my videos. When they are good. I say that they're good. I praised several Polk models for good design work, two models from Mono Price, several Golden Ear models, a recent Emotiva model and a new Heco Aurora model that I just shoot a video on, but has not been released. Our upgrades are not just different, they involve significant improvements, and our customers confirm that every day.

Exactly what I was thinking. It's too dark to see

We are working on it.

Ah man. I am sorry. I can't do a thing about that either.

$11.99 per month plus tax is one of the best purchases I have ever done (to remove them) as those damn commercials are maddening!

@@pelked1Are you sure that’s what you’re paying - I just got bumped to nearly $19/mo at end of April.

Oh man, we have done upgrades for a LOT of Klipsch speakers, and more than any other company.

Really? They've done TONS of Klispch speakers. Look back on old videos.

@@dannyrichie9743sorry! I should have clarified more vintage heritage Klipsch products!

​@@dannyrichie9743Skunky Designs heard ur MK 2 upgrade speakers from Amazon and sent em back... Flat sounding or something

Send one in.

He doesn’t do that. You only see the schematics big you buy the kit. But I agree that’s what we need to see to learn more

@stephenyoud6125 I'm not going to buy his kits because I don't have any of the speakers that he does kits for, but I want to play around with old speakers that I have and understanding some of his techniques would be interesting.

Only in some frequency ranges.

Distortion is actually more marketing than a real number. There is no industry standard for measuring distortion. It is also impossible to measure distortion accurately outside of anechoic chamber. In other words, the room noise or noise floor in the room is always present in the measurement. However, the whole thing is still a variable just like the room noise. Even room noise levels are constantly moving around. It is also easy to make the distortion numbers be anything you want them to be just by changing the input level. At any normal levels the distortion is not going to be a factor or in any way a measuring stick for quality until power levels are such that compression starts taking place. By far, the stored energy that we see in a spectral decay is a much greater distortion from the original input signal then what is going on in the harmonics of the drivers. For that matter the resonances of the cabinet is by far a greater level of distortion. We seen instances where the application of No Rez alone will knock 15db or more of actual measured cabinet noise. Normally, measured distortion in THD of a speaker that is playing at 1 watt/1 meter levels will have distortion levels below ambient room noise and will be in the 45 to 50db range. So it is not the factor that those in marketing would like to make it out as.

They will hold a residual charge that smears the sound.

Steel is a ferromagnetic material, like an inductor core, that gets alternatively energized and de-energization with the audio signal. Due to the alternating magnetism, with the hysteresis delays involved, there will be some time smearing [along with some tiny signal loss]. Asymmetrical audio signals cause a retention of magnetism in the steel nuts, which then only serves to make the aforementioned phenomenon even worse. Sorry for the verbal diarrhea. 😳 Good day. 😉👍🍺

@@robinkleinsteuber5217 That is helpful information, not verbal diarrhea.

I liked the 60 and 100 models.

Yeah, but a lot of people want them to sound better than that. It is also not just what the charts show. The differences in clarity, detail, and resolution are the result in a huge upgrade in parts quality.

Ah man, we use the crap out of the lift table.

I don't think so.

Have a look at our Bully model.

@@dannyrichie9743 I just finished checking them out. "wow" very impressive. Not what I am looking for unfortunately. I need a very aesthetically appealing cabinet (ie. Kanta's) or my wife will not be happy. These will be placed in our (new) open concept living room. That being said, I would absolutely love to hear the Bully's.

@@clasvirhodes4969 Come hear them. They also look really nice in the veneered cabinets.

@@dannyrichie9743 I would love to but, not a big fan of flying. The older I get the more anxiety i experience while flying. Plus this whole "DEI" crap being forced on airlines is unsettling to say the least. That being said, just having a conversation with you would be worth the cost.

It is paralleled onto it and limited to the top of the top octave.

@@dannyrichie9743 great job by the way 🙂

??? Someone that does the same? On KZfaq also?

Yes, the mids have a sealed back. I should have mentioned that.

Absolutely false. Pioneer's DSS and Elite speaker line are if maintained properly rival Canton, Tannoy or any other high end speaker line of today. I know as I own Pioneer's DSS-9 and smaller DSS-7. I bought both in the mid 1980s.

Looks cool tho

If you get them cheap, like buying them at an estate sale, putting in a few hundred dollars makes a lot of sense. If you get them expensive, like from a vintage audio retailer, then putting many more hundreds of dollars into that makes no sense whatsoever.

Well, you will get a special speaker. Not your average Pioneer from BestBuy. If you want something this large and beefy, you’ll need to pay a lot. See it as a fun speaker, fun project. Compare it to the KLH or Wharfdale ain’t the same. Search all life for something better, then you get nothing.

And never for the overprized Level of 900$/€. Joking. A good upgrade with jantzen high end components is for 400€/,pair.😅😅

Not so perfect? Old speaker and old drivers. What did you expect? So this speaker that are more accurate then before, it’s not good enough for you, when we go vintage? What’s your choice of speaker?
