This pictured looks very similar to what I had. I want to get it just for the heck of it, but have no need for them.

If the price is right, and you have the money to spend, why not? Isn't that what we do here? Buy stuff we really don't need? :lol:


I was pretty big into car stereos in the mid to late '90s. I normally ran two "12 Kicker Competitions, and sometimes my friends 15" Kicker Solo-Baric along with them. :mrgreen:

Not to mention in the case of consumer audio some of the older stuff is better than stuff you can buy now, so not much performance drop-off if any. Surely factory systems are much better and much more integrated so it makes it difficult to just throw in an aftermarket system. I worked for Harman until 2012 when I started my own company. I designed both pro audio and consumer audio, including many of the car audio premium systems... including the Infinity Kappa Perfect line (Perfect 12.1 sub, Perfect 5.1 & 6.1 component systems) as well as a lot of the JBL GTi series including the 60th anniversary 560GTi & 660Gti component systems. Rare earth & other materials were already getting super expensive in the early 2000's and the stuff we were making by the time I left, from transducers to amps, were not as good as the older stuff.

How is JBL these days? Is the quality still there? I have a soft spot for them since I still have my L100s I bought new in 90 or 91 driven by the same old Carver I bought at the same time.

I have some more recent JBL amps. I think that they are as good as anything else in the same price range. They hold up good and put out well above rated power.

I don't think that they are on the same quality level as my late 90's Kappa stuff. But that could be said about most stuff.

I have JBL architectural speakers throughout my home being run by an OSD amp and I’m thoroughly impressed with their power handling and audio quality. Especially for their size.

The short answer is 'ok'. Fortunately, they survived the attempt to move almost everything overseas - and still have amazing engineers, facilities, and the necessary resources to design the best stuff.

The long answer is that they aren't exactly what they used to be. A familiar story for sure... in 2007 Harman was bought by private equity group KKR. They bought a CEO who had no experience in consumer & pro audio, might as well have been heading up a company selling toilet paper beforehand. There was no respect for the legacy or the amazing top-end loss-leader products that kept the prestige intact. They tried to move the whole engineering department to China. They started bringing in engineers from China for a few months for us to train - but that's not what they told us - they thought we were stupid. We didn't exactly help them. They kept telling us there wouldn't be layoffs. The morale was extremely poor. We went from designing products on-hand in Northridge CA to writing 200-page product specifications for the team in China to execute. With no advance notice whatsoever (but we knew) they had a round or two of layoffs and treated career employees like criminals. Shortly thereafter the whole plan backfired spectacularly. They couldn't execute anything properly at the facilities in China. In general, the folks in China are amazing at copying stuff, but can't design a paper bag. They were trying to replace hundreds of years of expertise w/ just new engineers. Nothing was done correctly, we would get six, seven or more prototypes of things and it would be wrong, wrong, wrong. So frustrating. Furthermore, we started finding counterfeit parts in products. Dare I say it was funny to us as we knew what would happen. One vivid memory is in 2011 they made a run of 50,000 JBL EON PA speakers and there was a counterfeit amplifier IC. It cost a fortune in time and money. They bailed on their plan and kept Northridge and other US locations open. Many employees were laid off but some survived. After a few more years Harman was bought by Samsung in late 2016 and it was a best-case scenario at the time. Many facilities remain in the US as well as other countries and some of the talent remains. It's not what it used to be as technology has converged as it has in all markets.. companies copy stuff faster and things start to look the same. And materials are more expensive, so some parts are inferior to what we used to be able to use, and it forces new technologies like the many variants of digital amplification to reduce cost.

yeah they definitely still have quality engineers. That stuff is still designed in the US. Every company has dud products but in general the stuff is very well designed as they still have the engineers and just as important the engineering facilities to design things properly. The hardest part was designing to a price point. JBL always had a high margin. A $1000 product was made for $100, whereas a competitor would have a $1000 that cost $200 to make. Usually they are function over form, generally the products would perform excellent but sometimes the industrial design would leave some to be desired. But they've got better in more recent years.

...but they'll likely never design products again that we did such as the A6000GTi 6000W amp, the W15GTi subs (designed by amazing transducer engineer Jerry Moro), or the 660GTi component system which was one of my favorite products I was able to design - they let me spec just about every part I wanted, custom designed a waveguide in a car environment, shipped with two sets of grilles one leather and one carbon fiber! And shipped in a custom case. This kind of stuff is not happening anymore.

I have the '70 Mustang Mach 1 now that is getting cash thrown at it like I'm begging for a divorce :lol: But yeah, I might get them to have for a just-in-case scenario.

Could someone explain the whole brushed motor slot thing.


I’ve got a 17t 3 slot Radon 2 in my 40th rere but I was told that is a crawler motor. I thought I was ok and it was a good 2wd buggy motor.

What makes a crawler motor different from a non crawler motor? What are slots? What is the benefit to higher turns or lower tur?

Is there a thread that explains this all?

The yellow & black 17 turn "3 slot" Radon 2 motor is not a crawler motor. 3 slot motors that are used for crawlers are usually more turns of smaller gage wire, like 45 or 50 turns.

5 slot motors are typically crawler motors. High torque and low RPM are desired for crawlers. Your Radon 2 is a higher rpm motor suitable for a racing buggy.

The number of slots is the number of segments the wire wraps around and also the number of conductor segments in the commutator for the brushes to send current through.

These are some Trinity 3 slot and a Tekin 5 slot armatures.

So if I were to get the 15 or 16 turn 3 slot motor for the DS I would be good? They aren’t labeled as Crawler motors and it’s what’s in stock.

It comes in 15, 17, and 19. I have all 3 and have run all 3. This is the 19 turn in my shortened comical RC10:

There also are some new motor options from Factory Works.

I might order the 17 t from FW’s.

That is if you can vouch for them 🤣

😁

I haven't tried a Factory Works motor yet, but they use the same parts that seem to be industry standard now (including Radon 2) for brushed motors. The price is good, and the dyno and break-in are pretty cool too. The guy that sells them seems passable as an ok person too. 😂

All this motor talk, are brushless motors still a thing in RC? I believe they were more for racing than crawling because they're more a high speed/low torque motor.
