    Has anyone done an A/B of their designed and built panels against a pair of, say, Magnepan .7s?

    URLs? Post reference? DIY design details of those compared?

    DIY means Do it yourself which means you can do what ever you want to reach your own goals or destination....If you feel the need to take a different path just to be unique then good luck with it but often times that path way is usually a dead end....The path that everyone should strive for is the path that yields the "BEST RESULTS".

    We've been down this road before on this forum. DIY is a continuum and you can jump in wherever you like. You can grow cotton and harvest trees to make your own paper woofer cones. On the other end you can use someone else's proven design and build a kit. Both are DIY but at a different scale. There is very little unique in this world, nearly everything comes from the sum of our experiences. Improving on other's designs isn't cheating the DIY system, it's progress. The hugely successful Pioneer HPM 100 wasn't unique, it was a copy in concept of another hugely popular speaker, the JBL L100.

    What I am saying (since this is a DIY forum) is build your own panels utilizing there DESIGNS at a fraction of the cost.

    Bar ... Isn't this thread about improving on much overpriced panels?
    I'm sorry DIY is dead because of easily available and cheap mediocre speakers and in most cases streaming. I won't be able to compare mine with the Bert's or even other DML's. I do believe I can best most. As I said earlier I don't believe in a one speaker full range system even with a sub. Mine will fly in the face of 90% of these postings. It's to be quad speaker/amped. Cost around $100 for the panels and exciters.

    Good, Unb ... didn't want to try do mass anyway, but will isolate brace from frame as best as I can. Getting anxious to hear. Slow going as I always build for as much experimential ability as possible, such as easily changeable panels and exciters. I do not build prototype sample, disguard and try another.

    Most people including DIYers don't realize the true potential of exciters/dml technology as most have not heard some of the better DML panels out there like Bertagnis and Podiums etc. Most start off and build Rich M's beginner design and when they are not satisfied with that build most usually quit, believing that is the limit to DML technology which is far from the truth.....DML panel designs are almost endless that have enormous amounts of potential but it will all depend on ones design.

    One of the unique features of my design is that there is three ways to tune the sound of the panels so one can tailor it to there own preference which takes less then 10 seconds to do....I already mentioned one of the techniques above.

    Actually a heavy mass is not needed to support the exciter magnet since most exciter magnets are very tiny, a simple brace aka spline is all you need.

    Almost forgot what I was going to ask ... Contemplating putting heavy mass (supported) attached to magnet to prevent movement instead of brace to frame. I alluded to this before, but too lazy to look.

    Unb ...more panels should have been built around the country so other people could get a chance to hear them properly. Initial ads showed them to be playtoys and stocking stuffers. Unfortunately for us DIY pretty much died out. I've tried to get others to do a little reading but not getting any results. I'm in new town so lost all my stereo friends. Streaming the top 40 has bitten them, too. I mentioned them to my good (stereo) friend of 40 years who usually likes new things and he very quickly said he was not even interested.
    I won't be able to demo mine properly as I'm in apt complex.
    I have an ext headphone amp for phone. It might drive 2 - 8 ohm exciters in series on a small panel for demo.

    I just revised my "Bastat", sats/sub DML panels using a slightly larger panel and a larger 19mm exciter instead of the smaller 13mm exciter.....The bass and spl has increased as well as the fullness of the sound....They are now even listenable without the sub.

    If I could display my panels at the Midwest audio fest I know for sure I could get more people interested and also realize the true potential of exciters/dml's.

    Yep, me too. Always wondered why the magnet moving back and forth would be good. Did think it might be a synchronous push-pull thing, but nice to hear a sound explanation. I will look for a good solution. First is a huge mass so force cannot move. From there I'm lost.

    I was always for bracing of the exciters....Why because it does 2 things.....The first is that the magnet of the exciter needs to be braced/held in place so that the voice coil has something to push off of as without a brace the voice coil will push off of the panel material and move the magnet instead of moving only the panel....The second reason a brace is needed is it prevents voice coil sag while the brace holds the magnet in place the frame holds the panel material in place basically like a conventional cone speaker which uses the metal basket as the frame.
