GR Research is cookin' up some very interesting "old school" 3-way (kit) speakers

Danny's objection to some of the Asian-sourced inductors is that the copper quality is just not very good.

While this may be of concern, how can he tell...just by looking at a wire?

Him being so into quality of parts and kits he offers, how do you interpret that he sent out an inductor looking like this (although the inductance was within specs):

...and not just to the average Joe, but to Audio Science Review, for Pete's sake. And then admitting he has issues with suppliers...and known issues with the cabinet. Being aware of that, his quality control of to-be-shipped parts/kits should be immaculate. This wasn't just an oversight and it's way beyond embarassing!

To show ASR is not just all about being vicious towards GR Research:
"Overall, this is a job well done by GR Research and I am going to recommend it to owners if they are not inclined to use my software EQ fix."

BTW...to anyone who uses the term flat Earthers...the politicaly correct term is spherically challenged.

Of the three kits I have received from GR-Research, all had new (unused) parts included. I know they had some significant supply chain issues in 2020-2022, so it's possible that this was the last one they had in stock. But I don't know.

It's clearly difficult to tell by just looking at the inductor if it is using good quality copper, which is why I would purchase from a reputable source. From my experience working with GR, I do consider them reputable.

For my most recent build, I sourced all my crossover components from Parts Connexion and HiFi Collective since I wanted to use different parts than what Danny supplies.

I see the problem with that inductor, there is no pixie dust on it to make it glitter as everyone knows the shinier the inductor the better the quality. :rolleyes::rflmao:

You quoting ASR post just further proves some of you have a grudge against Danny just because you dont like the way he talks. Heck I talk in a similar way that Danny does but I am way worse. lol

He doesnt need to listen to the speakers.

Really? The guy who is redesigning the crossovers doesn’t need to listen to the speakers? Isn’t that like the final test of your work? Who cares if it measures flat if it sounds like ass.

Not all speakers that measure flat sound the same. Because none of them are perfectly flat.

Yup its just common knowledge for DIYers. If you are only designing a crossover based only on a FLAT FREQUENCY RESPONSE, then one does not have to listen to the speakers at all because the measurements do all the work.

If it sounds like azz something is wrong with your speakers to begin with. :rflmao:

It should be not all speakers sound the same regardless of a flat frequency response. There are no perfectly flat speakers but the goal is trying to get it as flat as possible.

Maybe the “measurement only crowd” is a real thing after all :)

No, you are just taking it the wrong way or you dont see it for what it is. When DIY your own speakers the measurements are just tools to help guide you through the process and can show you why you are hearing what you are hearing but the final say is what one prefers personally.

Majority of all high end speaker goals is to design a speaker with a relatively flat frequency response because it will have the most "BLANCED" sound. Small peaks and dips here and there are not a problem as they will emphasize how one wants to voice there speakers. When there are big peaks and dips then it can sound unbalanced.

Exactly what performance problem (distortion, inductance value, and such) would that cause? It looks like it's bonded together correctly (loose windings would obviously cause issues), and as long as the copper is decent quality, what else would go wrong, functionally?

I have quite a few issues with some of the stuff Danny does (his cabling is sometimes pretty bizarre, to put it mildly), but I don't readily see how that inductor is causing anything other than a possible cosmetic problem. If it's possible to save a significant amount of money compared to an inductor that performs identically but looks better- is there any FUNCTIONAL reason to use something else other than this, for a "budget" build?

Regards,
Gordon.

I don't like watching videos of the technical aspects of audio equipment when the camera is focused on the person rather than the component or schematic.

Perhaps you misunderstood me due to language barrier...on my part, that is.

Mr. Richie is quick to diss manufacturers (of speakers in this case) - he might be right...or not...(his yada-yada videos don't cut it) just by looking at crossover-components. I'm confident he can identify some problems at a glance - he surely must saw a lot of bull in his career. But...as I stated: no issues with performance of said inductor, it's his observations and declarations of poor construction (winding thightness, shape and whatnot), just by sight, that bothers me, so...?!

I find it curious:
- in his videos he posts frequency-response graphs which don't go below 200Hz
- I actually agree that there's no need for him to listen to his speaker stuff...if the technical parameters/measurments are good, the speaker/kits are good as their reproduction is as close to the source/recording as possible within a certain budget/price. The sound they produce might not be to everybody's liking/perception, so his opinion on how they sound is more or less irrelevant in general
- yet he doesn't provide any technical/performance data (let's overlook safety regulations at this point) of his cables and emphasises that only listening to them will tell/show THE difference.

In my opinion he is a used-car salesman, yet I care to give (or point to) credit where credit is due. Not with his, or anyone's for that matter, power cables though.

I don't see anything wrong with a "budget" build....fun, saves cash, visual scheme to personal preference, etc.

Borut

You seem quite confused.

One most certainly can see some components in a cross-over are cheap/shoddy upon nothing but a visual inspection. It is pretty well accepted that Air core inductors are better than iron core inductors, and poly/film caps better than Electrolytic. These are easily identified in three seconds by a visual inspection. And yes, to a lesser degree, internal wiring (thin gauge wire) can also be pointed out. No reason for any speakers that cost over $600 to be using these **** parts, IMHO.

The reason he does not "listen" (to a stereo pair) as his customers generally only send him one speaker. Why? To save on the high cost of shipping.

Safety regulations? Really? He most certainly does provide before and after testing data, what is it you are looking for?

as for the "no testing below 200 hz" this has been explained ad-nauseum on his page, if you have not seen it explained, I suspect you have not watched enough to be a critic.

Cabling might look bizarre but functionality wise is straight to the point

Really?...with power cords?...prove me wrong (show me the before/after data and the 200Hz ad-nauseum explanation)!, I'm eager to learn.

Yep, I have not wtched enough...I'm just a consumer...silly me!
