DIY Speaker Builds Troels

[Adolfo0728]

Hello, I'm a newbie to this forum but I've been building DIY speakers for many many years now. Everything from Jeff Bagby to Troels designs in any finish you could possibly think up. I joined this forum to try and learn a little more about the electronic side of the equation. I've mastered the cabinetry part now I'd like to gain more insight on the component side of things. Looking forward to this journey with you all.

Do you have any studies in inductive and capacitive reactance as well as principles of electron flow?

Hi Doodski, no studies in that. I've learned a little along my way from real world experience here and there. I've used inductors and capacitors and I know that the flow of electrons is from negative to positive but on a scale of 1-10 regarding knowledge and studies in that regard, I would say i'm at a 4 and not ashamed to admit it.

Nothing to be ashamed of. The quantity of people with a formal education in reactance and principles is pretty rare actually. It's a fascinating study for sure for a newbie. I have zero experience with computer software crossover design but maybe that would be a good start? There are people here that know about this.

I like your cabinetry.

I am building a pair of JBL M2. I like the speakers, one of many end-game speakers which I would be happy with.

The components and DSP area all available.
The design was measured by Erin with his Klippel.

I have some musings on prototypes:

JBL M2 Clone

I recently measured a JBL D2430K compression driver and M2 lens. My goal is to build an M2 clone. The speakers are going to go into individual boxes allowing me to stack the woofer and D2 into an M2, or even include a midrange. I got a pair of B&C 5NDL38 for cheap, and if they don't work I...

JBL D2430K Measurements

I have been interested in the Project M2 DIY Thread for some time. I helped a friend install a fabulous home theater with 708i, but I have been fascinated by the M2. Recent reviews of the 708i were interesting, especially given my positive impressions of the speaker. Erin's review of the M2...

I learned quite a bit building these.

I am working on the finished version.

Cheers and good luck, no matter what you build.

Your woodworking and finishing looks really top notch, nice.

As far as electronics go... I will just say that if I were to DIY a speaker in 2024 I'd go with a fully active design, probably based on the Hypex Fusion plate amps, which AFAIK are the best DSP amps sold to the public.

Much, much easier to create complex filters this way, no serious trade-offs except cost and maybe a little latency.

I recommend that you acquire a copy of Vance Dickason's book entitled "The Loudspeaker Design Cookbook" 6th edition. Vance is a respected authority on all things Loudspeaker. There may well be a later edition by now; if so, get it.

Second this and would add Joe d'Appolito's "Testing Loudspeakers," which will give you a good handle on how to validate (and correct) your designs.
