Dynaudio 2 way DIY with automotive genes
Hi folks,
So I have been wanting for more than a decade to build a regular
2 way speaker for a secondary audio setup in a smaller room and
after many years of search, finally spotted a chance to buy tweeters
with pushed in domes( kids
) and a pair of MW 160 GT for a good
price. The box used to be a floorstander initially made for some
other drivers by another individual, sawed to a measure I felt right
about.
I was so curious to do the paint job myself and not having the proper
spray gun equipment, decided to apply the paints by brush. For priming
the raw mdf I had a 1k auto primer and as a finishing coat I chose the white
marine enamel. My plan was to apply at least three very thick layers
of enamel and then sand it down wet with 1000 grit paper.
I can tell you, now I appreciate much more this kind of work because
it is so much time consuming and a drag to do. Could only do one
side at a time so it dries over night. Those primer and enamel were
such bad smelling chemicals, I had to use a face filter mask.
With each layer of paint the surface looked much more even.
After the sanding process, glossiness was gone which I partially
managed to get back by polishing. The end result is a semi gloss
appearence. For the money invested, which was not much, I am
satisfied.
The speakers are playing very openly with enough of bass extension
considering bassmid is an auto speaker unit with a higher Fs and
lower Vas parameter than 8 ohm versions. Especially the vocals
and high frequencies appear unstrained and natural.
Vb:16,5 litres BR
Fb:52 Hz
Sensitivity: 84 dB/2,83V/1m
XO frequency: 2,2 kHz
Filter: LR4 acoustic
Bassmid: Dynaudio MW 160 GT
Tweeter: Dynaudio D260 Esotec
Thanks!

Thanks 6th, I had used up 2 cans of 750 ml enamel so I could sand
them without worrying of breaking through. Tweeters were damaged
and on account of it cheap, just what I was hoping for. I did everything
to set them right but unfortunalety the silky material with its coating
just jumps right back. The impedance and FR measurements were ok
so I chose to be at peace.
Your speakers are work of art compared to my cuboids

Dear,
It's a loudspeaker with 3-way, passive crossover and high sensitivity.
I used the woofer JBL 2226H, PHL 10" as mid and Fountek ribbon for the high frequency.
Below are some photos:

10 inch dedicated PHL mid driver
Hi XMax,
Congratulations on a nice build!
I have used 6.5 and 8 inch PHL mids and loved them in sealed cabinets.
I am interested in your thoughts on the performance of the 10 inch PHL midrange.
Which model & impedance is it...There are a few variations!
I have always wondered how it's dispersion would blend in with a good ribbon or AMT?
Where do you cross it over?
Please tell me you are using a nice DSP crossover and active amplification....Your great cabinet skills and high quality driver selection deserve the best!
Thanks and good luck
Derek.
