Damn guys, I'm just having a conversation and trying to learn of his knowledge.

I really respect his work and I'm not bashing his products AT ALL.

What should I do, kiss his ass? Maybe I'm on the wrong forum, but I thought it was meant to share thoughts and learn from eachother.

I'm not trying to pose as knowledgeable at all, I'm a complete noob compared to him.

I'm just sharing what I (think I) know, so he can correct me where neccesary.

I was going to type a reply to mr D'Amore, but maybe I shouldn't and just let it be.

its the way you came out about it.. you made seem more like you knew what you was talking about and not a personal opinion.. you also questioned his knowledge and never asked how he did it

[lutkeveld]

What are you trying to imply fresh prince?

I'm not trying to correct or teach mr D'Amore at all, he should be teaching me if anything.

As said; I'm just trying to understand his design choice, which he did a great job of explaining.

Now I know more than the day before, great things right?

asta la vista baby

What are you trying to imply?

that you made it seem other wise.. also seem cocky when saying prove me wrong instead of asking if you was correct. its just the way you said it

He has no need to teach you anything. He doesn't owe you anything.

You don't deserve anything from him or anyone else because you have no respect for people and their efforts based upon your comments. If you have a question there are ways to ask it. These people are giving away free advice, at their leisure to people in our hobby. A little respect for their time and everyone elses on this forum would be a good thing for you.

This isn't a engineering forum, he is not presenting untested findings to you. In fact I regret ever saying anything about an amplifier because of your comments.

this guy really has no idea who tony is

youre arguing against an engineer who designed amps for a living

here are pictures of the most efficient amp aver made.. even after the years no person has come close to building something like it

Hey guys thanks for the props!! Yes it is true the idea came from a defibrillator. It seemed silly to me that all these guys in the db drag lanes need to have 1/2 of their vehicle full of batteries and alternators to maintain a decent B+ voltage for a few seconds. That and the fact that the amount of total energy all those batteries contain is huge and they are only using a fraction of it during their burp. It is like taking a NASCAR car to a drag race. A vehicle that is designed to go 200mph for hours on end probably isn't the best design for a 1/4 mile burst. So when you look at the way a defibrillator is used its like burping an amp. Defibrillators don't have massive power cords that need mega amps at 220V, in fact some of them are portable and run off a very small battery. Why, because they don't need to shock someone for hours at a time, just a quick burst. They just draw a small amount of power continuously during 'charge up' and once all the energy they need is accumulated they release it all at once. With the operation of the defibrillator in mind, I tried to apply it to car audio. I set off to build a prototype which was based on (2) T1500.2 output sections, I had to liquid cool the MOSFETs because even the FETs in the T1500.2's were not big enough to handle the kind of power I wanted. By keeping them very cold they could be pushed beyond their limits. (This may be the radiator ect... part of the story that someone posted). Then I needed a way to store a bunch of energy, electrolytic caps and some of the carbon based caps that are commonly used in car audio were not even close to being capable of storing the amount of energy I needed, so I used 12 small motorcycle batteries in series to get 140+ Volts. Then I built a power supply that would convert 12VDC to 140VDC to 'charge' these batteries. I got this contraption all put together the night before the Annual Rockford Fosgate Employee Sound-Off. I didn't really how much power it would make exactly, but to try to shorten this long story it ended up putting out 15,030 Watts RMS! This is how 15k Watts became the goal for a 'real' amp. The first step towards making it a 'real' amplifier was I had to eliminate the array of batteries. I began searching high and low for something that would do it. I found a company that makes capacitors for hybrid cars and large wind turbines. These worked perfectly. The caps I ended up using are 400 Farads, and there are 180 of these in the T15kW. Then I needed an intelligent power supply that could monitor these caps and add energy to them as needed, and it had to be fast, really fast if this amp was going to play music and not just a burst. So during music these caps are charging, discharging, charging, discharging. The power supply in the T15kW can charge the caps 35,000 times per second. Of course many other things had to happen like finding MOSFETs that could handle it, a way to keep it cool without antifreeze and car radiators ect. The final product met all the goals and then some. The main idea is that with this technology the amplifier can put out more power during transients or bursts than the car it's connected to could supply. Again thanks for the props, look for hybrid technology to hit our smaller amplifiers in the near future. PS if you guys would like to see pictures of the original liquid cooled proto I'll post them. This proto was eventually dubbed the D'Fibrillator. haha

how did I not see these pics before now! The only gut shot I ever saw was the cap bank. Thanks for posting Miguels, and ya know thanks Tony D for designing it

Maybe i joined the wrong forum then. A lot of the things I said/asked/stated were just out of interest but get taken way out of context. I'll leave the discussion for now. Thanks again mr d'Amore for developing this product and taking the time to answer my questions.

Who argued about the price??? Shit is dope.

This forum has a standing reputation for ahole-ness. There's more guys measuring their "wiring harnesses" on this board than I've ever seen. Try not to get too worked up over it. A few of your posts did seem a little strong. But no worries. Take a break from the forum for awhile and come back on a new topic later.
