Default celestion 5"

1.13mm is one way movement. This looks better and better but what about fitting it into the enclosure??

IF you want to use this in Tabaq:
Bjohanessen made the Tabaq cross section equal to 4 x Sd so you may have to make cabinet slightly bigger. The vent cross section may have to be calculated again though. What about the upper freq being only 12 kHz - is that enough for you?

If you want to use this for the wall hanging tml it is not as critical, model with hornresp if you have time but I think it would work fine as is since the dimensions are very wide.

Hi xrk071
Ypu can alter the dimensions (with and depth) of the TABAQ as long as the cross section is the same, e.g. make it wider and not so deep. The port opening has to be lower to maintain the same area.
Just reading the specs, I would expect this driver to do just fine.

Bjohanessen,
Can this design be taken to the limit of very wide, a flat box for wall mount, say 2.38 in deep x 8.34 in wide to maintain same area? Thus the speaker can skip BSC as there is essentially no baffle step? One thing I like to do with single driver designs is to avoid adding anything between the amp and driver electronically. This will boost available amp power too. What are your thoughts?
Thanks,
Xrk971

I've been thinking exactly the same. It would get the driver up to any hight you'd want and would make BSC redundant. Toe-in could be handled with four hinges to swing it slightly out from the wall, if necessary.
You could invert them, put the port on the top, closest towards the wall and get wall and ceiling loading to further enhance the bass (like a BIB).

I did something similar to this with my wall hanging TL suggested by Sayrum by flipping it upside down and resting it on a shelf (a mini refrigerator actually) with ports firing up at ceiling. The shelf puts the drivers at ear height. The bass rocks with this configuration! I still have yet to try the TABAQ in a full size and am thinking a wall mount makes sense for me as I have no floor space for a speaker.

Would anyone happen to know if the Tang Band W5-1611SAF 5" full range would work as well in the TABAQ folded horn as well as the bamboo 4"'s do? Would a larger box scale up ok?

Correction: TABAQ is a folded TL, not a folded horn....

That looks like a nice driver. Bjohanessen will have to confirm, but I don't see why it wouldn't work. You need rpto grow cabinet dimensions to get cross sectional area at least 4 x Sd. Usually w 3 in driver a high Qts is needed to pull out lower bass but this driver already gets to 60 hz.

Hi Mario I will come back to you when I am off-Android :-)
The 4" works well in my TABAQ. You could use 70g stuffing iso 100g and also place the speaker 5cm higher up.
I have designed - but not build - TABAQ LARGE for TB5"
