Building Dynavox DIY Speakers
Can you just do-it-yourself and save money and get something better?
Let Us Get Started
Nothing fancy here. What this DIY build aims to do:
- Buy a prebuilt set of boxes
- Find some decent, but afforable drivers
- Build an afforable, yet good quality crossover: no iron core inductors, no electrolytic capacitors
- Use very high quality wire
- Use high quality acoustic foam; no poly fill cotton candy
- Enjoy for low $!
I ended up going with a Dynavox driver set, after all it's my opinion they are cloning or at least trying to resembled Dynaudio. And there is nothing wrong with that. At all. I picked the Dynavox LW6004HR-N 6.5" Honeycomb Cone Woofer and D-2801XL-M01 1.125" Soft Dome Tweeter. The specs:
The response is pretty smooth and these seemed like some very high quality drivers for the money and the reviews were typically very, very good. And in my experience, that's true. Here's the drivers and the built crossovers:
I like using this perforated metal base and silicon because it has dampening and prevents rattling. The silicon oozing through the holes makes a very strong, yet ultimately removable connection and it is uper easy to cable tie all your componets to.
Note the output wires are soldered directly to the terminals for the best connection possible. And the completed speakers (well one of them):
The sound quality of these speakers is actually very good, and the 6 ohm impedance makes them extremely amp friendly sitting politely between 4 and 8 ohms. The perfomance is very, very good for the price and better than many cheap speakers you'd get just walking in a department store or odering some imported no-name off of Amazon or the like. I used these happily as my desk speakers for a long time, which were ultimately replaced with upgraded Bowers & Wilkins 606 S2s. For a similar build and cost, you'll get better results doing the Elac Debut 5.2 Upgrade project.
