ADS C2000 Clone (RSM C1000)

I have been in a collaborative effort to recreate a C2000 (bass extender not in this proto). I have been given the schem for a multi purpose board that can be populated for the appropriate speaker and will allow bi-amping of the 1290/1590/1230/1530/2030 for those that DO NOT have a C2000 or equivalent to do so. I am currently in PCB design to create a Gerber file and BOM. I have been given values by the other two collaborators and I will check in here later for verification before fabrication. Proof of function testing will be conducted in about three weeks before fab. I will pop the boards and have a rudimentary craft box design. I will then beta test for proof of concept with 1290/1590/1230/1530 that I have access to. I have a friend with 2030 for that beta once ready. Folks, do not get too excited here as we are in prototype phase but I believe we are onto something. I feel very optimistic.

Why stop there? Go further and start your own speaker company. You have a good ear, experience, and obviously the curiosity and love for music. Go for it. Study and put out something to blow us away please!!!!!!!!!!!!!!!

Geez, I wish. I don’t have the expertise for that at all. I am literally learning as I am moving forward on this project. I have outside help for many of these steps. Once the board is done design and fabrication of an appropriate can for it will need to be made. There are many, many others here that are more experienced than me. I do, as you say, have the love for it and maybe it’s the push I bring to the table. The execution part maybe. Man, that would be very cool though to make a speaker. The RND of it would take a substantial investment and a sustainable market for it may not exist.

Anyway…. Let’s see if this even works first. On paper and in application are two very different things. It could be noisy, degrade the sound, or even unstable and damage a driver. Like I said, I am optimistic and hopeful. I have a C2000 and will also A/B on my 1590 for the first run. This isn’t even to make money. This is just for others to be able to enjoy their ADS the way I heard mine when I bi-amped. It was incredible.
 
Extra points if you triamp!
I always thought that the problem is that woofer is 90degrees out of phase , which causes a big dip around 400hz ( I forget the exact number ) and flipping the polarity doesn’t help.
With that in mind, any external crossover would work if you add phase control ( like the variable phase on a subwoofer).
 
Well, here we are!! Boards are in. Now I will source the BOM and pop. That can take a couple of weeks I'm sure. Then see if we are in business...

I have 10 boards for 5 crossovers. If this works I may make some available for bare board purchase if you want to build your own. Not trying to get rich here folks. Stay tuned!

I know it’s been a while and things are busy this time of year, but wanted to say I’m looking forward hearing about the results and would love to get a board if the project is successful!
 
I've not been getting regular updates on this thread Tim, so I've not seen the progress just lately. That said, your an awesome fella in every way. Thanks buddy!

Sorry everyone... The holidays and end of year work has sucked up all my time. Progress has been stalled but not forgotten. I intend to get back on this January. Some part sourcing has proved challenging. I will post an update when we have our first beta testing. I hope this will be in January. I was really hoping to be further along, but life is a stubborn bugger... Cheers!!

No apologies necessary Tim. There was nothing for years and now we have something. People can wait a little longer. You get to it when you get the time to get too it. This project should be fun for you, not a burden. Personal work before the other stuff.

I just stumbled across this thread. I have set of ADS L1230's and had a C2000 that I bought with them The C2000 would quit working from time to time and I had id repaired but the last time I took it in they said it was unfixable. The L1230's sounded so much better biamped with the active crossover that I ended up putting them in storage and am using something else. If I could find a crossover to use with them I would really be happy to listen to them again.

I don't see where this alternative crossover became available. Is there any news on the status of this?

Did your repair tech state what the problem was that made the C-2000 unrepairable?

I actually don't recall as it has been more than 10 years ago and I am not that knowledgeable with electronics. They had repaired it twice before when it dropped to only having sound on one channel. It was a place called Desco electronics in Olympia Washington. I called around to other places in Seattle but no one was interested in working on it.
 
Folks, I need help. My family went through a bunch of flu’s after a cruise we had. Then I got so backed up at work I am in catch up craziness. I need someone to help me source and pop this board to validate. I can but won’t be able to get back to this for some time. I know this is something everybody is waiting on but need help for help in next step. Once validated, the person who can help will get that board free. If valid, I have a fab company local that can make a nice case for it. Sorry everyone, life gets in the way. Everything done so far has been R&D and I have paid the money to get us this far, I will also be paying for fab design too. I don’t mind doing it either, this is bigger than money. I just need someone to jump in from here. Heads up, sourcing parts have been difficult. Anyway, PM me and we can go to next steps if you’re the person.

When you say "source" the board, do you mean a manufacturer? Who made the ones in the photo?

I used ExpressPCB to design and layout some boards for my old job. They deliver high quality stuff for a good price.

No, I have the boards made. The ones in the picture I have ready to go. I just need someone to grab the bom and the board to get the right values and size to fit the board. Just takes time and I don’t have it right now and I know this project is overdue.
