it depends but 18 db id say.
its diffecult to get a nice flat responce with this driver,but i was aiming towards 50 hz rollof,see if i can get it better.
edit/ something like this?

Not for one with a 94 dB sensitivity.
It will be a lot more than 86 liters when the wood is added in.
If you like a "natural" sounding bass guitar speaker, you will want to cross over from a TH to a front loaded speaker, the frequency and phase swings (even though they will be less than Hornresp predicts) do not sound good, even in comparison to something like the old Acoustic 360 folded horn bass cabinet.
no no, slight misunderstanding .... sub is for hifi 😉 and just modest and relaxed casual listening 😀
these two 8" Seas Prestige woofers looks interesting for this, good quality and not expencive

Since you are "green" on TH, tell us about the rest of the system and your plan for bass integration.
Focus grasshopper, there are tonnes of good designs here you apparently would choose not to build. What do you need that is not already offered?
Still need an answer to the previous question...

That's about a subwoofer, and no measurements? We don't care about that, we are going to replace that...
We know one thing: Sound quality IS a priority.
But at the same time we have no idea what that means to you because you abandon measurement..?

I dunno man, you wrote it...
Absolutely right - from start my speakers were measured with the finest tools and software, and I was very disappointed to hear a saxophone or a violin fore that matter - it sounded like they vere playing in a concrete cellar, bloody awfull - after YEARS of adjustment by ear it now sounds almost right, almost - and I wouldnt dare measure them now
In my youth I only could afford cheap fullrange in horns, maybe it has been to some advantage, allthough if I return I might be disappointed
Anyway a TH is basically a two octave device with a group delay peak at the top, if you want more bandwidth you should look at a T-TQWT, and it should be adequately dampened. bjorno would be a good guy to tap for a design IMO, and I would be happy to draw it up...
Dan, you are a funny guy
interested to hear what kind of TH you like, have built, or is using ?
and yes, a bandpass might be better for me, but its not folded 😱
but I have an idea for that too, but since you are not interested...cheers 😀

Thanks,
I'm not heckling you at all. I'm just working with what you provide.
bjorno uses MJK worksheets and other processes that differ in that resonance can be dampened, end result is that he can provide something with visual appeal... T-TQWT is also more HI-FI oriented in my view. If you were to characterize the sound of your sub via strengths and weakneses and back that up with measurements that would be HUGELY effective as a development tool. I know this is near impossible and not a serious request, moreso an explanation of logic. Did you build the/a large format/non-movable sub? If so may we have the details/measurements if available?

still interested
no, I have never built a sub in my life
and yet; I do remember a very big triangular corner TL with 8" Dynaudio
unfortunately the plate amp was not yet invented
so it was never put in practical use
shame to think now it might actually have been good
well, whatever, I dont have any good corners to use now
