Finished my TABAQs today. They still need a proper paint job, but I had to take them in to test them.
I have only tested them for 20 minutes, but I'm impressed so far. They disappear in the room and sound nice and clear.

I recently came across an unusual Scanspeak full range driver at Madisound, the 10F/8422-03. My understanding is that this 4" driver, which sells for $22, was made for the Japanese magazine "Stereo".

Does anyone have a pdf copy or scan of that August 2012 Stereo magazine article? I can't find anything online. Of course, it doesn't help when you're using english to search for pdf versions of a Japanese magazine. lol

Hi Marc,
Most of what I was able to find was through Google Translate, attached in case you have not tried it. I also "Googled" images and there are some designs but finding dimensions, figures, etc., is not easy.

I am thinking of getting a pair just to play with, Tabaq or bass reflex.
Please let me know if you find anything.

Thanks Rick. I've been going through a similar process. I bought four drivers from Madisound to play with. I'm going to use two in small, full-range mini-monitors. The other two I'm going to use with some Silver Flute 6-1/2" woofers, electronic crossovers and bi-amped.

Finally finished the paint job and placed them in the tv-setup.
In this room they really transformed. I suspect that visitors will look around searching for the subwoofer. I really didn't expect that kind of bass from those small shoe boxes.
Are you running a BSC circuit on those away from the wall?
Nice looking work BTW.

Thanks.
I'm not running BSC. I use DSP for a +3db low shelf filter from 150Hz (personal taste) and notch filters at 2800 and 10 000Hz.

Glad results are similar in other places of the world!
I have the same TB driver in my TABAQs now, and use the same notch filters, but I do not add the +3dB low shelf.

I found those notch values in one of your posts. I don't notice much difference with the notch at 10k, but the one at 2800Hz makes a huge difference.
I finally got my active version finished and varnished. It's based on the shortened TABAQ that Bjørn kindly simulated on post 1396 and uses a W3-315E driver.
It's a single cabinet with an extra compartment containing a Class-D amp and bluetooth module with aux-in.
Many thanks to Bjørn for the original inspiring design, for answering questions and verifying the sim! The speaker is now sat on a shelf in the kitchen.

I now plan to replace with a better driver, since you have givena thumb rule of fs100hz for 3 inch. I am able to source this peerless driver.-Peerless S07NE,with the following specs. Kindly suggest whether this is a suitable driver for the TABAQ box.

I looked at post 1396, but couldn't find the dimensions. Would you mind sharing your dimensions? I have a pair of those drivers just waiting for the right project.
Thanks!
