Millercarbon's Mega Moab Mod Meander


One of the all time great automotive engineers, Norbert Singer, was a key player in every one of the 16 Porsche LeMans victories from 1970 to 1998. His dominance was such that at one point Porsche had won LeMans more than all other marques combined. This was all accomplished by building on the already solid foundation of Porsche production models. The air cooled flat 12 in the 917 was really two flat sixes combined to make 12. This car so dominated motorsport the rules had to be changed to stop it!  

So Norbert Singer modified Porsche production technology to extract the absolute most for racing. His legacy is today’s Singer Vehicle Design https://singervehicledesign.com Norbert doesn’t make for a very good car name so they called it Singer. What is a Singer? It is a modified Porsche. It is in essence a hot rod. What Norbert Singer did was make the most hot rod racing Porsche. What Singer does is take that to the next level, capturing every aspect of Porsche right down to excellence of design and aesthetics.  

I am not anywhere near the level of Singer. But that is the spirit of what we are doing: taking an already world-class design and hot-rodding it to be even better. Well, better for me anyway- or so we hope!

The early modders started with substituting off the shelf parts to get more power or less weight. That is pretty much all we are doing here. Would be cool if some day people are doing this with a lot more sophisticated approach. Maybe they will. Maybe even I will. For now though we have the current crossover project.

My approach is pretty simple: better parts sound better.  

This lesson was learned back in the late 90’s with Linaeum Model 10 speakers. The designer had a new tweeter and told me how to modify the crossover for it. Simple mod, one cap, one resistor. Bought the parts from Radio Shack, put it together, sounded like crap. Absolute horrid crap! Called him up, he said those parts are crap. Said Musicap, Vishay. But they measure the same? Just do it. I did. It worked. Even though they measure exactly the same, the sound difference is off the charts.  

Even though they measure exactly the same. There is a lesson here. For those willing to learn.

So this is the essence of it: Eric Alexander has made a speaker the equivalent of a Porsche 911. Even better: an affordable Porsche 911! But after a while with my 911, after learning what makes it drive and feel the way it does, it was only natural to change the shocks and torsion bar and other items to bring out even more of what I like so much about the 911.  

That is what we are doing here. Hot-rodding a speaker. Thank you Rick for the metaphor!  

The parts are on order. Next week the fun begins!

Trying to figure out why people here hate on Chuck Miller @millercarbon so much.

It is as if they lurk like vultures just waiting for Chuck to post.

Me I rather enjoy his posts and appears others do to by the number of views his post get.

This place is a like a High School. 
Keep up the good work Chuck and the free rent in their heads. Even though it may seem like a tiny house.

Sad little people. 
You have no idea.

Just got word both shipments- caps and resistors from Partsconnexion, inductors from Madisound - are out for delivery today!

Got a PM from Ken nmmusicman with a good point, doubling up resistors in parallel the wattage adds together and this increases dynamics. One cap it was hard to find a single high quality cap in that value, so I combined two of the same model, which is the way to do it. He feels mixing types or models of caps in this situation can smear timing. Whatever the reason I am avoiding it by using a 6.8 and 8.2 uF Alumen Zcap to reach the 15uF needed for this cap.

I know it is just a bunch of caps and resistors and coiled up wire. But this is like Christmas morning with a new Lionel train to set up. I had the one you put a few drops in and it even smokes. Maybe a bad metaphor. No smoke. Definitely prefer no smoke this time!


Went looking for video of Singer founder Dickinson saying in his own words exactly what I said, that it is Singer after Norbert Singer. Because I know he said it. Came across this along the way. When you have something you love constantly being trashed in public it is exceedingly painful. This member deserves to be banned for life from all things audio. He has nothing to contribute but hate. He is the antithesis of what we are doing here. Listen to Dickinson. He is saying what I said in the beginning. We just need to satisfy performance, and we do that in a reverential and celebratory way. https://youtu.be/_3WswVaHLH4?t=198
