TABAQ TL for Tangband

Bjohannesen · 2017-01-24 9:47 pm

Nice!

The impedance is as predicted by MJK models.

Note that the lower peak is damped which indicates less cone movement below the tuning frequency. Something you dont see in a BR.

Have fun!

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.

When I did the stuffing, I thought that the 4in version should have more stuffing then with 3in. I felt that they were lacking some bass, so I reduced the amount of stuffing a lot. Now they sound amazing, even my wife was impressed.
Thanks for a great project.

Nice! So what are your plans for the bigass speakers in the background of the second picture?

Thanks.

Plans for the bigass speakers, replace them with something larger.

I just connected the TABAQs to my main rig for testing, I built them to use in the TV room where we sit closer to the speakers.

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".

Rick

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.

Rick,

Glad you got it right!

The 4 inch had a lower Qts and should have less stuffing. Still upper 2/3 but with lighter density.

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.

mightym · 2017-02-01 10:24 pm

completing a build currently, and considering a Tabaq with the Dayton RS100-4 as next project, with a dedicated Bluetooth amp for a bedroom/office.

I have a Mini DSP, but use it to work out XO configurations. I'm a purist for straight line reproduction otherwise....

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! :up:

The speaker is now sat on a shelf in the kitchen.

HI BJohn,
Thanks for the tabaq design.I have been using the tabaq box variant with a vifa tc9fd, kevlar cone speaker with a Fs of 123 hz.I found the sound stage and clarity better with minimal stuffing only at the upper 1/3.

tnvijay · 2017-02-05 3:49 pm

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.
Impedance 4 Ohms
Frequency response 100 - 10K
RMSE - Free 0.78Ohms
Fs 100.87 Hz
Re 3.43 Ohms
Res 11.86 Ohms
Qms 2.28
Qes 0.66
Qts 0.51
L1 0.10mH
L2 0.31 mH
R2 1.74 Ohms
Vas (SD) 1.27 Lts
Mms (SD) 2.67 Gms
Cms (SD) 933 uM/Newton
BL (SD) 2.97 Tesla-M
SPL ref (SD) 88.5 dB
Rub -Index 0.06
Area (SD) 31.17 Sq.Cm

Thanks in advance.

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!
