Thanks Jeff! I've used a tilt of 5 degrees. Good idea about the filter. As soon as I got the BSC I'll try the two different setups. See what works best.
Thanks Kissabout. I'm already enjoying the music! Maybe I also just needed to get used to the sound from these beauties, but I'm going to try the BSC anyway and as Jeff already suggested, just try what works best.

Hi Bjohn,
I recently made the second pair of Tabaq box again with 25mm MDF. This time i used your
Guidance for a bigger Tabaq.i.e. 178 sq.cm and port size 21sq.cm. I used a 4 inch Full range which i was previously using in the original Tabaq Box. I noticed the SPL did increase than the previous one, the low mids are more open, But i miss the deep low grunt that the original Tabaq offered. Any suggestions? I made sure the line geometry is correct, no air leaks. How much stuffing should i do?
On experiment ,i notice that the more i stuff,the bass becoming more deep,Is there any suggested quantity of stuffing?
Ps. I place the Tabaq against the wall,and no BSC

It does not make sense to me. Which driver are you using?
For information I have enclosed some examples of stuffing. The cross section is smaller than your loudspeaker but you can see that increased stuffing damped the low bass a little.

Hi Bjohn,
Its a generic Taiwan import driver. It's called as Dainty in India. No Ts parameters, but it performed extremely well in the original box Tabaq version. I fixed the same driver in the new box. The sound is much more open, and i would like to know if there's any simulation for stuffing with this cross sectional area. Thanks in Advance

By interpretation of the graph, do i understand correct if more stuffing reduces bass? In my experimental stuffing,i did notice the opposite.
Hi Bjorn,
I wish to update that with a BSC filter of 1.0mH and 6.8 ohm resistor, brings out the deep bass that was missed earlier. Now I have a Tabaq,with same sound quality that i liked but with more loudness.
P.s- The Tabaq is still kept against the wall

Hi Bjorn,
Thanks for the pdf. I have used the same dimensions i.e .171sq cm large Tabaq. It requires a BSC to achieve perceivable bass,But this larger version plays very loud,with peaking upper mids and highs. That being said, i liked the bass of the 128sq.cm Tabaq much more. Hence,i dismantled the box , Cut it again to reduce the width. It is now back to original dimensions,and as usual,i get that deep gruntling bass again. For 4 inch,i feel the original Tabaq is the best version, subjectively ,since i have heard both extensively.
Regards,
Vijay

tnvijay, where did you get the information about a TABAQ with 171cm2 CSA?
None of the TABAQ plans that I know mention that number. The original TABAQ is about 122cm2. That's why your first one sounds better. Your second TABAQ has too much volume and is not tuned for the drivers.

Hi perceval,
Look into the pdf by Bjorn in post 3327, In page 2, there's a simulation with increased csa. -171sq.cm . Bjohn has given this simulation sometime back in a older Post. I used that and did the Tabaq with larger volume. But finally, I am back to the original Tabaq with Csa 128sq.cm.

Oh, missed that one. Maybe it was only for that TB driver.
So far, I’ve been really pleased with the original design.

indeed, the original design is simple, small and great sounding. AFter building the tabaq, i stopped using subwoofer for music. Tabaq gives the most natural bass for music listening. i did a frequncy sweep test and monitored the airflow at the vent by means of a small paper ribbon pasted on one side of the vent. i noticed the airflow was maximum( greater amplitude of vibration of the paper ribbon) at 55 hz.
Because the TABAQ design is tuned to 55Hz.
For most music, that is enough, but for more involved music, like electronic, it often dips below that.
Boz Scaggs “Thanks to you” is another.
Still, the TABAQ to me is the most satisfying design when it comes to bass extension using a 3” or 4” driver, and with the right driver and filter, quite satisfying with upper extension too!

It is such a simple design, that building it with a 3D printer would either need a very big commercial printer, or print it in layers, so in fact more trouble than assembling a few panels together. So many layers to glue, you get more chances of having an air leak.

Hi,
Has anyone tried to build a Tabaq with this driver?
3″ SB10PGC21-4 / Fiberglass - Sbacoustics
And if not, do you guys think its a viable choice?

I did.
It was suitable for the design, but the drivers have a break up that brought a lot of distortion.
I forgot the frequency it was, but I remember it was annoying to my ears.
Found it in the sb10 thread.
There is a distortion bump at 3.8kHz.
It may or may not annoy you.

That's a shame, because the parameters looked good.
Is it the peerless element that is top contender now or has any other element
arrived recently which has great bang for the buck ratio?
