Yes, 17 F-ing min about subwoofer spiders - spoiler - they all the same bruh @ The Robot Underground 

I can literally listen to this guy all day 😅

Absolutely love these videos, I wish more people went into the truth about all these “technologies” that companies claim to use. Very curious to hear your opinions on sound quality in subwoofers and what effects it.

Love your unfiltered knowledge on this subject!! I am a noob and trying to learn and I enjoy hearing your experienced input👍👍💯

These are the conversations I have been wanting to hear.. killer content

Very informative ! Been a car audio fan for 32 years and I'm now more informed than ever thanks to your videos. Thanks my friend

The coffee statement is freaking hilarious 😂 😃

The dampening system on a trophy truck is highly tuneable and is very important to the performance and speed of the truck through the course.

I don't consider this a rant, it's more like a lecture. Hope you don't get much flack for sharing these "industry secrets" because it helps the consumer make a more informed purchase. Thank you and keep up the good work my guy

Only 17!?! Slipping Patrick...lol j/k another great vid!!

JL audio12w6 v1 from the 90s tech used a composite ring adapter on stamped steel baskets to increase spider diameter size and add more linear travel.

A decider lol reminded me of American Dad!

Can you please do a video on power handling/ proper power for the best output and efficiency?!?!?

When you're talking about Neil, are you talking about the Neil who used to be in Sacramento Neal's speakers? I used to go through him to get speaker parts and reconing done.. He's not in Sacramento anymore and I've moved on to doing some of the reconing myself. Anyway, just comes down to parts and he had OEM certain Vegas stuff back when I was into those

The suspension thingie is my current ache. I like what B&C spekers company does, but their spiders are tightening too steeply near Xmax and Xvar, spending hundreds of unnecessary Watts to reach such excursions. Easily 360VA to Xvar. RCF on the other hand, in the same class, hangs between 130-160VA. A noted difference. So yes, spiders matter, but there is nothing one can practically do about it. Like choose the one to his liking.

keep em coming!

pfft... red spider... what about the classic bright yellow spiders!

The proverb 'A little knowledge is a dangerous thing' expresses the idea that a small amount of knowledge can mislead people into thinking that they are more expert than they really are, which can lead to mistakes being made.

Mind blown same spiders as my 9512i and 9512j but claim to be special special for the vc I guess

I learned so much from watching your channel. Keep it up 😋

3:25 goes for Robot underground also...

It’s 3 seismic audio SA-GFC12 subs. All three with the same problem. The SA-LAF has the same basket. after 6 months of use or less…I only noticed it was fucked when I went to swap enclosures. 😢

This channel is hidden gold

I know it's an old video, I go watch older vids when I've seen all the new ones. I'm not insinuating Im highly educated in the world of subwooferology, Anyway as far as progressive spiders knowing what progressive is and how progressive vehical suspension works which is going from large softer coils prgressing into stiffer tighter coils as to have a soft ride but as travel moves it gets stiffer to handle load and maintain control... So my assumption of progressive spiders is initial softer ribs to allow efficiency and low FS for deep sound while on lower power levels but as more wattage is applied and excursion goes higher and soft ribs max out the stiffer ribs take over to be able to take more power while still maintaining control and avoiding over excursion, kind of like a soft spider and a stiff spider in one. Does it work or work or even well....? Linier will get stiffer as it moves more also but is going to start out stiffer and have a higher FS. Am I right I duno just my guess from what I know about progressive suspension on vehicals and it does work in that application. Obviously a correctly applied linier spider works fine also...

This is too funny..

You got any tall cupped spiders for 1.5 inch Vc? I got an old Rockford that needs some love. Or would it be better to make a spacer ring to rise a flat spider up?

I just want to say thank you thank you thank you very much for the knowledge for the helping us out

I have some 90’s pioneer IMPP’s the free air ones have a higher roll spider compared to the sealed application ones. And the free airs are stiffer. Yep it’s a lot of physics

Hell I thought progressive spider was comparable to like a aftermarket progressive spring for a car’s suspension.

Madddf science drop ppppppppeeerrrr

I love you robot

Hi Pat, I am having subwoofer problems. The inner spider detached from the coil ,The glue joint didn’t hold good enough. It’s just a cheap subs but I want to fix it. Is this something that should be covered under the manufactures warranty? What type of glue should I use if they don’t? It’s in a tight spot

👑🔉

I fucking love yer vids you genuinely crack me up sometimes yer great ......I really wonder sometimes though old systems I had back in the day that really did kind of defy the odds or physics or whatever... Idk like exactly why in the hell did a pair of Rockford cheepy series one twelves inverted into a massive 8 ish plus cubic feet sealed single chamber box on 200 watts in an old school box Lincoln town car hit so redicoulously hard...and hit the ultra lows super great too. Idk everything is different now gotta have a ton of electrical system to even get close

I heard that Joe Jackson playing :D

i always thought to break in a sub was for rubber surrounds . i live in ct and when winter hits i find you need to let car get warm before subs on with my old hx2 15s needed to "warm up" before bassin off the snow on the car. 2002ish had 2 hx215s in a 93 sentra with 2 crossfire 1100 amps in a 3.5 cub tapped horn . loudest i got with it was 161db and that was after i dumped 5 gallons of foam in the trunk and closed the lid . before i encased the box i wwas hitten 155 . i encased the box into the trunk and then filled all the panels doors and roof . it was almost a grand in foam but werth every penny to gain 6 db !

How are they all the same when some are so easy to bend / flex and some are very hard to bend / flex? The softeness/hardness level affects fs. The stiffer/harder the spider, the higher the fs will be.

These things do duffer a bit. It is just that one cannot rely on the differenca as a game changer or problem solver, really. Noone is going to notice dditional 1mm further stroke with given distortion, noone is going to notice 35Watts of less heating based on extended compliance with stroke. It is just that making things better for sake of it makes sense. It is then ruined by BS claims by the companies as explained.

What kinda battery is on that Bosch impact driver? I got those bosch tools. I wouldn't mind having a better battery

can i trim the outside diameter to fit the spider landing?

I just found your channel from another guy who built a 15 w7 and I really want to get into building custom subs and I want to build something that has a good amount of excursion but I have no clue where to start

Dd says don't play your subwoofers at full volume for a few days? I understand why now? The guy at fi told me to play my subwoofer at medium volume to make sure the coils were hooked up right and not out of phase? And after a couple of hours let them rip 😆

DD Audio laminated spider with a layer of foam between spider? yes,no? ive seen the foam. what is this?

Can you reverse spider sag?

Hope all is well wondering if you can tip me in on a few questions I have about soft parts

whats the best spider now days for long xmax extension

Mr Chan I want to but 2 8s the new ones

How can i contact you personally to get a subwoofer built

Do you have a video on coil size?

Lmao u test all ur subs so u can call bullshit. I guess I got the shit end of that stick cuz the quad stack w/3" coil I bought off you must have been tested on its good side cuz within a week I was getting a crazy knock from inside cone assembly leading to a slightcoil rub. Drove me crazy. I really didn't want to make the drive to mesa so I didn't take u up on warranty. And really wanted to figure out y and learn how assemble a blown sub because it's a great thing to know when I'm prone to killing shit because I'm ignorant and am learning what limits r in an audio system. I honestly believe for some reason maybe a clamp got shifted or w/e but the coil wasn't quite aligned. So I bumped it as if nothing was wrong and a month l8er it finally ate through the former and shorted coil. I no u preaching soft spider heavier coil = good performance but I couldn't believe how loose and worn the spider was after disassembly. I couldn't get a proper liner travel with it after replacing coil. And the stupid knocking was the support dust cap. Stupidest thing to have to figure out of noob like me. But I did eventually get it bumping again after replacing spider with a triple layer one and now the sub works great I really like the way you built this motor and honestly don't hold nothing against you cuz I know you would of fixed it without a problem once u heard the floppy middle support cap knock the cabon dust cap. Sounded terrible. It's on me for not utilizing ur warranty. But just thought I'd bring it up cuz the commit in video. But I know you're ego doesn't come before humility. So keep doing the kool shit u do and making videos to educate noobs like me

Always goos shit

Swastika is thousands of years older then hitler and the nazi’s. Nazi’s killed Jews who were also white I don’t know why everyone uses Nazi as a hate symbol towards blacks when they hated everyone who wasn’t a nazi period. This is why we need to stop erasing history in our country. We are all the same race human. We have different ethnic backgrounds and skin colors based on adapting to living conditions that’s it. We adapt and survive. We fail to survive when we kill each other over ignorance. Dang sorry good video I just sick of ignorant people judging others by appearance of the content of each other’s character. Oh and there’s two genders male and female. Biology.

So dd audio is full of shit ?

What do you think of the Avatar STU1246 subs
