Yeah that wire is coated with varnish so to use it you need to scrape off the varnish about a quarter inch on each end. Then you can solder it. Easy peasy. I was wondering about dml amps for guitar amps Nice playing btw. The exciters are a bit weak I think, Maybe to clean not enough natural distortion. I wonder how using spruce for it would sound.
Yes one thing is that it's quite 'sterile' sounding - very clean. I also haven't tried it with humbuckers... or a different amp/head. So many potential combinations!
Great video, the bass or low mids seem a bit absent. It might be the little Hotone mini amp is a bit shrill. Not that your speaker sounds shrill and no ice picky highs, its treble biased but sounds smooth so that's a great start. You could try running your Fender SS amp through the test speaker if the amp has a phono jack socket to plugin the speaker, just plug in your new flat panel instead. The panel seems very small to reproduce lower frequencies. I wonder if a bigger 500 x 1200 mm bass panel with a bass exciter hung behind the existing one might fill in the sound? You'd need a simple crossover too. There is a flat guitar speaker recently gone on sale from Eminent (not Eminence, different company), it's not much larger than yours.
Thank you! I agree it could use a bit more 'grunt'. There's no phono out on the Fender but I might try just wiring the output to the panel instead of the speaker for the next attempt.
Thanks! I was originally going to make something wall mounted but I like this version. The parcel shelf Idea is interesting, though you could use it as an actual shelf and listen to music at the same time I guess…
Nice idea Ben. I’ve not seen anyone else make a DML guitar amp 👍 I wonder if 2 exciters would provide a richer sound ie less top end and fuller mid-range. If they are wired in series you wouldn’t then need the 4 ohm resistor too.
Thanks. Yes that's possible as well. I just went with what I had already but there's definitely room for improvement. Worth noting that the 24w exciter I used also has pretty 'good' HF performance compared to some others which works against me here. I do plan to make a 'v2' as I can reuse the same acrylic panel easily enough (the most expensive part of the project). Since I now have a router I'd like to try cutting a channel into a single 'frame' and mounting the panel in that rather than sandwiching it between 2 frames. I'd also like to see if I can amplify it internally so it can be a self contained unit.
@@TypicalBenYT: Yep, that's the problem. Some folks burn it off with a flame, but that leaves a black residue with a re-annealed copper wire. I usually just scrape it with a razor blade or knife in a back dragging motion.. When it's all bright and shinny looking, then it's ready to solder. You'll quickly see the difference when you start scraping the enamel coating off. Cheers 🍻
Yeah, that's the whole reason you can make inductors, coils, motors, and speakers with it. The non-conductive coating prevents shorts when it comes into direct contact with itself. Electromagnets, transformers, anything that uses a coil
Thanks for doing this. I’ve been wondering about this. What material did you use and thickness for the “speaker” panel? Also, do you have any perspective on how efficient the output of the DML is compared to a traditional speaker? I assume it is only 75% as efficient (loud) if you were to swap back and forth between the two. But maybe you’ve checked that out? And I assume it compresses sooner if you hit it with full volume when compared to a normal speaker? Thanks!
Thanks Matt. I did gloss over some of the detail in this video sorry. The panel is 3mm thick acrylic with a printed backing. In this configuration (acrylic, rigid) it's not very efficient. Other materials and mounting options would be more efficient if you need the volume however. When I'm messing around with this stuff I'm always trying to walk the line between getting good sound and making it look good - having said that it works well for my situation with the little 5w amp. I had it set to about 70% volume and 40% gain in this demo. Your last assumption seems to make sense to me although again I haven't done rigorous testing. Again, you'd get more out of a larger panel with more compliant suspension I suspect.
👍 Cool man. Are you sure that wire is not coated? Just scratch some off and away you go. Imagine an entire band using just DML amps with those bending waves engulfing the audience.
So, ive thought about doing a project like this and was wondering if you had considered putting a more comprehensive EQ between the amp and "cab"? I imagine if you left the resistor out and integrated something like the circuitboard from the Sonicake IR pedal, you could have more more "classic" tones or at least more variety.
Yeah I’ll look at doing something like this in ‘version 2’ I think. I was thinking something like putting the innards of a line 6 pod into it somehow actually.
Really interesting idea! Weird that I'm all into 'hybrid' speakers for my hifi setup but didn't consider it for the guitar one... Thinking about it now though!

Love it! Liking the small form factor too. Makes me wonder if a similar design would work well in a car mounted into the parcel shelf...

Looks like wire used in motor winding i.e. coated for insulation. Scrape off the coating for electrical connections
What they said.
Thank you- I think you’re right I’ll try this later!

@ 9:47..... Yep, I couldn't have said it better myself! Cheers man 🍻

Ahh ok that makes sense. It’s called ‘enameled copper wire’ but I didn’t realise that’s what it did. Every day is a school day!
Thanks for your research! Fascinating.

This with a couple of 8" semi-subs to handle the low end would be great.

Cool.
