I did not add yet the BSC, I want to try first as they are without it also because I am using a tube tone stack bass/mid/treble so I can compensate, in fact I had to lower the mid on some records, but anyway I will do the BSC in future and see if I like it. If you talking about the ring that I add to the driver is not wooden but plastic I got it on Ali 2 Pcs Universal 4 Inch Car Speaker Solid Washer Adapters Brackets Speaker Mounts Plates Speaker Gasket for Cars-in Speaker Mounts from Automobiles & Motorcycles on Aliexpress.com | Alibaba Group, I really did not like how the Faital's looks with the open basket and visible fixing screws but now they are more acceptable with this simple plastic ring, thanks again Perceval for your work and help 🙂

Hi John,
I use the original plan, this was suggested by Perceval as more effective for this specific 4" driver....all the best

Here you can see the ring better how it looks, the only problem is that is 4mm bigger than the enclosure but still acceptable, using a 16mm plywood the enclosure comes 8mm wider 13.2cm instead 12.4cm

JC Tang Band W4-1320SJ

I have a pair of Tang Band W4-1320SJ for my next project.
In the original TABAQ the 4" is a little weak in the 80 Hz are, which can be solved by reducing the stuffing by one third.
I have increased the volume a little, the cross section is bigger.
In the document enclosed you will se how stuffing helps de damping of the cone - the lower impedance bump is reduced - without loosing too much on the low end.

Thanks, I would love to hear your opinion on how they sound when you get them built and if they need BSC.
I modeled the 1320sj in the Leonard Audio program without stuffing. In the first two graphs the bass around 65hz peaks higher in one, and in the other the bass extends out a little farther toward 50hz. Which do you think is likely to sound better?
In the third graph I tried moving the port up in the cabinet off the floor. In the simulation this appears to have the benefit of suppressing the harmonics between about 200 and 800 hz, which suggests to me that you could get away with lighter stuffing. Have you tried that and is there any disadvantage to moving the port up off the floor?

Hi JN
I always use a slottet port. The port is a part of the line, with af smaller cross seciton the last part to achieve the mass loading.
I have simmed that TABAQ will get less bass in the living room if you rise it from the floor (mount it on the wall).
I move the location of the driver trying too avoid the peaks and drops.
I am not afraid of stuffing, this helps controlling the cone movement, especially below the tuning frequence. In a BR you get noice and unctrolled movements of the cone below tuning. You do not see this in a weel dampend TL.
About BSC: I use external filter, so it is easy to test with / without filter or modify the filter (more Ohm). See picture attached.

"Stuffing upper 2/3 of the line. Light (0.2 lb ft 3 25 gram), medium (0.5 lb ft 3 63 gram) and dense (0.9 lb ft 3 112 gram)"
Is it 25gr total?
Is it 25gr total?
Hi Solve
The stuffing is the total, you measure the filling and put in the box. The more weigth the denser stuffin, of course.

Hello Bjørn,
I got myself a pair of W5-1611SAF for the TABAQ large.
I was just going over the drawings, and wanted to double check something...
You mention that the vent length is 12.7 cm.
In the drawing, the vent is 10cm block with 19mm MDF baffle, that's a length of 11.9cm.
Wouldn't that come too short a little?
Your drawing vs real scale drawing of the vent:

TABAQ Large Port
Hi perceval
The port is actual too long. My bad 😀
Take at look at red line in the image enclosed.
The drawing has to be adjusted, which I have not done yet, but I am sure you can figure it out. There need to be a pice of wood at the back wall and the 10 cm shelf should be adjusted.
Hope this helps !

Hi Perceval
Your 3 cm is not 100% correct.
The length of the bend is
Half the hight of the port: 1.55 cm
The thicknes of the 6.3 cm "bottom": 1.9 cm
Total: 3.45 cm
The 9.7 cm is actually 9.75 cm
However, this is not a big thing.
Hope this make sense ?

Great ! Thank you.
Together we manage.🙂
Normaly two half brains is not working. 0.5 x 0.5 = 0.25 😀

Finally finish the second Tabaq with Faital PRO 4FE32 , I decided to do not try the BSC I really love as they are, I can manage over the tone control so really no needed in my case.
After tested with all kind of music I realise once again how fantastic are this small driver, but the thing that really stand up is how they working at a very low volume, clear and incredible full body low freq. for a total warm music experience, the SPL of 91dB really make a difference especially with tube amp.
I did them for my wife so I said to her: " darling, what about a generous offer, I give you the TB W5-2143 and I keep the new Tabaq, well cannot say the bad word follow my request 🙁 , so that's it 😀
All the best

Ha!
You'll just have to sit and listen to music together!
See, the TABAQs are great for getting couples closer. 🙂
