Default My interpretation of the TABAQ.

Hi guys (and girls?), Raymond from the Netherlands here. After building my first set of speakers (the Cyburgs Needles). I really, really needed to build again. So this time I got interested in the TABAQ thanks to all your input.

First idea was to build them the way @bretti_kivi did, which I thought was really clever by lifting the whole speaker and adding weight.
But then I remembered the Boenicke W8 speakers which are also small but a few degrees tilted to get the drivers more at listening height.

So I decided to combine the TABAQ design with the tilting idea. First made the design in Solidworks 3D CAD.

I've used 22mm MDF. Made them look as if they are made from concrete by adding some imperfections and put some amount of time in hand painting them to get the right uneven concrete grey.
I used the Tangband W3-871, same as in my needles. Also used the same filter: 6.8ohm, 0.56mH, 6.8uF.

To be honest, I'm not totally fine with how they sound right now (I've used the drivers from the needles so they didn't need extra play-in time). To me the mid/high tones are too loud compared to the bass. Don't know how to correctly describe it, but it's as if the driver itself is more present than the speaker as a whole. Don't know if this makes any sense to you guys .

My plan is to change the filter to the original designed version from @Bjohannesen. 3.9ohm and 1.0mH. To see if there is any improvement.

If you guys have other suggestions, please let me know.

Cheers.
Raymond

Using 1.0 mH would be a better choice. The 3.9 ohm could be increased to 6.8. Test it to see what is working best.

Did you stuff with 100 gram leaving the last one third of the line unstuffed?

Hi Bjørn,

Thanks for your reply.
Yes I stuffed it exactly how you described it.

I'll order the parts today and test it. Very curious about the difference!

Those look like some serious bases. Are they actual concrete? Second the job on the finish, nice result.

Hi Joe,

Thanks for the complement! Seems I succeeded pretty well in the concrete look, because the bases are made of MDF (two layers) as well :-).
My previous build, the needles, were unstable so I wanted to make sure this time the cabinets would stay where I put them :-).

I must say these bases in combination with the 22mm thick MDF makes for a nice weight. So I'm pretty happy with the result.

Very nicely done, Ray.

You got painting skills!
I like the tilted base. I just might do the same with one of the pairs I have here.

And you might consider keeping the filter you have, along the BSC you will add.
I don’t know of the frequency response of your driver, you’d have to measure and find out.

But maybe the BSC will be enough for you, or maybe a combination of both will work. You’ll have some time to test.
