DNA2 Build
01/05/20 at 05:00:00
 
With the help of a 'friend' I am building the DNA2. I can show what I can show, and I won't show what I can't about the build.
I am not even done with the build except to say that I am now trying out a few drivers. I have built the original DNA model, and so, this is an enlarged version. Because I have already had a chance with the first build, this one is a bit better.
Let me get to the point. When I completed the first set of DNA speakers last year, I knew that they had the sound that I like so much. I wanted more of it though, and so when the second model was released, I waited for the plans to come out. I waited long enough and was fortunate to have Mr. Ziggy give me some tips.

 I tried the Audio Nirvana drivers first, and it wasn't a match. Waaay too much bass, and just a sonic signature that didn't do the classic 8" ALNICO driver justice. They actually sounded better in an open baffle.
Now I am trying out the Mark Audio 12P which is a big brother to the 10P that I used in the first DNA build. I can't express the difference between these two drivers except to say that the 12P just has more. It goes deeper, and has a certain presence that I haven't heard since the FRX2.

Holy shit, I did it!!! I'm calling mom.

4krow,
I'm glad that you got everything figured out for your build.
Have you tried the Silver Flutes yet? I'm a big fan of those drivers.

Donnie,

I am so gobsmacked by the 12P drivers, I may JB weld them permanently into place! I know, I know, the curiosity factor will draw me in sooner or later. Here is an interesting thing too---- I was using a directly heated tubed input stage to feed a class D Hypex type of amp, and the attack is really good. This morning though, I turned on the amp and it blew a fuse, forcing me to go back to a Carver A220 amp. Oh no, not only that but I have an amp out there that is being remade. Yes, an engineer from Denver who used to work for Sudgen is working on an old Forte' 3 amp that I have had for many years. It is nearly done, and I am excited to hear what it has to offer.
Yes, yes, I know, what about a Decware amp? I have owned a few of them in the past, so don't doubt for a minute that one will be selected in the future. Actually the Torii Jr. would fit the bill. Choices, choices.... I am in heaven listening to Pink Floyd--- Endless river like I have never heard it before. The DNA2 design gives me exactly everything that I want. I'm in love.

4krow,
Looking good. I bet they sound great.
I have not heard the Mark Audio drivers yet but hopeful sometime in the future I will build something with them. Most of my builds used the Fostex drivers. What wood is that front baffle? That has some nice grain to it.

What I especially like about the Mark Audio drivers is the LACK of shout associated with most full range drivers. Yes, they have a bunch of dazzling features incorporated in them as well, but in the end, the sound is something that won't let me leave the couch or skip a track as often on a CD.
The wood is box elder, popular for turning bowls. Interestingly, this slab sat in my woodshop for 10 years in rough form, as I considered it unimpressive. So, imagine my surprise when I planed it down and saw what all the roughness was hiding! It is a softer wood that is for sure,and I have hoped that the 1 1/2" makes up for it.... it did.
 You may notice that the drivers required an adapter since it seems that no two 8" drivers are the same diameter. I originally planned for the Audio Nirvana to be the first choice, and routed an 8 3/4" recess along with an 8 1/4" through hole. Having said that, I am now tempted to make an adapter ring from 1/8" brass!- and use it for the mounting adapter.
