I'm having problems soldering a sundown aluminum coil to the tinsel leads. Can you recommend any flux and solder for aluminum that I could find in Europe? I've tried some that need high heat but my 70W soldering iron can't melt it well enough. I've also tried some aluminum fluxes with leaded, lead-free and silver solder, but none of them worked. I saw GS audio sells a kit for soldering aluminum coils but it's very expensive for one or two recones.
@woldemortxyz7996 4 ай бұрын
Also, can I use a "burnt" coil to recone? It still measures good and doesn't seem to have any loose winds. It had been removed because it rubbed somehow, but it's just a bit burnt and if I just recenter it well, shouldn't it work well again?

First car I was ever able to hairtrick with was using a sealed box in 2004. Tc based subs eq'd down low just like you mentioned. Kinda funny that to this day a lot of modern "designs" that perform well start looking a lot like what thilo did. Jacob has some linear bl tech coming out supposedly. I wonder what his solution is? Didnt tc build some drivers for kef? I know they did for quite a few other home audio companies even monoprice for a while. Is this kef thing in the newest issue or just on the site?

Well it's important to remember that he shares office space with Nick Lemons. Nick lemmons developed obsidian audio as well as stereo integrity. Stereo integrity uses XBL technology from Dan Wiggins formerly of a dire audio. So it's probably going to be a reintroduction of XBL but he may call it something different since he is supposed to look like the boss of everything
@666nacirema666 4 ай бұрын
@@RobotUndergroundthilo made the mags for him way back too didnt he? I think youre right about using xbl as I remember seeing some posts where he talked about using it mixed with their own bl flattening techniques or something to that effect. Would be interesting to see him actually do something that isnt just derivative and a more extreme version of things already done. Ive got some younger friends in the local car audio scene and they seem to think this stuff is magic. So when I say things like what these guys are doing is barely different then what dr jensen did a couple generations ago they often think im being a "hater" or some bs.

The main reason these companies do these wild and often pointless designs is exactly like you say: gimmicks. Also, they know that home theater guys will pay a TON of money for it. Once in awhile a company will actually come up with an actual new design or concept (Sunfire/Bob Carver, or Thilo for sure), but so few and far between it doesnt matter much. The exact same subwoofer (especially home subs) performance can be had with the normal standard subwoofers, but thats not "fancy". The guys that buy this stuff listen with their eyes (and wallets) before their ears. They will see even a TINY bump in frequency on a graph that doesnt even matter in most sound recordings, and you will never convince them that they cant actually hear that at all. EVER. lol. Most of the mains speakers you see, even somewhat lower to moderate priced gear can be fixed with DSP (obviously not cheap garbage white van style crap) and other software tweaks and placement anymore. But again, thats not expensive and fancy lol. Home theater is another funny thing...but i wont even bother with that (NEW! 17.5 Dolby Digital Ultra Virtual VIsual Audio Playback, with 4D Audio processing!! LOOOL). A lot of these companies DO do some R&D and sometimes it matters a little, but no one ever stops to think (although i think ive heard Patrick say something along these lines once or twice) "if it worked, everyone would be doing it", or everyone would be making a knockoff of it. The only real difference in home subs that matters is generally the size of the drivers and power behind them. Home subs as well as car subs are only using a relatively small frequency band, so what REALLY do they need to accomplish? Most well rounded accurate home stereo systems will not be more than a few hundred watts total. Maybe 5-800 at the VERY most. Anything else is just power and volume for power and volume sake...also bragging rights. No one REALLY needs the same output of an actual movie theater, nor the the same output as a medium to large concert venue. Hell, when i saw Godzilla vs Kong in a nice actual theater..it was WAY too loud, and almost intolerable at certain parts. I 100% guarantee that if you put a head to head of stereo systems from reasonably priced, to incredibly expensive with the same volume settings, with the same tracks most of listeners (even the audio snobs) would hardly tell a difference. Now add DSP/EQ to the lower end gear, and again, youre going to see more and more people being able to tell less and less difference. Its hilarious to think about. Dont get me wrong though, i as well as most of the people here love it as loud as possible, and the fancy gear def catches my eye, but its not ALL about the visual appeal in an audio world unless you cant have it any other way lol.

I watched this whole thing and you never explained the purpose of it, you seemed to not understand it's purpose and therefore it must be snake oil. You kept calling this a review, but you literally talked about everything BUT the product and it's purpose, type up a script dude, bullet points, something other than just umming your way through a 20 minute "review" where I'm left hunting for ANY relevant info. There's some great videos on KZfaq about Pro Audio Cardiod Subwoofer arrays, look one of those up and maybe you'll understand the purpose of this project. I can type an entire dissertation, but just watch one of those videos. It's not snake oil, it very much has a specific purpose, and you're damn right us guys with money and a specific need will pay extra for a product that actually does what we're looking for.

"we did this!" instead of thinking "should we?" edit: looking on ebay there is one... pair of these drivers for sale... looks like they have some kind of feedback output in the sub on one side to let the amp know whats going on... holy hell complicated for no reason...
