Finished mini speaker with TB W4-1337SD

domtw · 11th February 2010, 01:33 AM

Hello,
I just finished a set of mini speakers based on the TangBand W4-1337SD

The official FR curve is really attractive but is missing a raised up band from 1KHz to 9Khz that I measured in a closed test box:

Taming this curve passively means quite a few components: one RC impedance correction, a notch filter and a 12db low pass...
That makes me feel the need to experiment on active crossover and equalization (minidsp?)

After many attemps here is what I got in the final speaker:

I am quite happy with the result, especially the sound stage. Of course real bass is missing but with a sub, it's OK.

This first attempt with a full range driver make me think that a good solution might be a 2 way speaker: full range + (sub)woofer

About the aesthetics, I made it with a very high WAF as you can see:

Those look really good!!

Do you have any off-axis measurements (the on-axis doesn't help much without them)

Excellent work! WAV is indeed high! Is the exterior a vinyl?

I have to do this measurement but it's gonna be Chinese New Year here so it might take a few days...

Vinyl on the curved sides and leather for the others.

VERY nice little speakers.
They probably sound great too with that tangband W4-1337.
Will you post the complete design with cabinet measurements and crossover please?

Very nice!

Neato! With all that extra hi frequency output with the driver (without compensation) it seems we can tailor their sound to suit our tastes.

They really look cool. Nice Work..... Wish I could hear them in real. BTW what equipments and tools did you use. Frequency response is really much linear. Not many small speakers would do this job. can you post, correction you used.
