First 2 way speaker - help

[Tesla88]

Hi all !

I have some skill at building/repairing electronic stuff but i'm a noob at speakers building.

I've bought 2 X Tangband W5-1367B from a friend since they were about 40€ the pair, which i thought was a good price, I know is not the best way of starting a project.

Driver specs :

Btw having this LF driver i put the T&S parameters into WinIsd, it suggest a Vented / BR box with 13 liters tuned at 52Hz, the -3dB point is at 50Hz which I think is not bad.
I tried increasing the volume to 16 Liters and lowering the tuning at 45 Hz, this should improve bass extension a bit.

So, the first question is : Whats is the right box tuning and literage ?

pics or it didn't happen, right?

Drivers (yep i have 2 W5-1367B and 3 W5-1367A ) :

Question 2 :
Now about the HF driver / Tweeter, can anyone suggest something good but not too expensive? Say 40 to 60 € for the pair is ok.
The LF driver should be fine up to 2.5kHz, right? is not hard to find a driver which can work from 2 to 20 kHz with a sensitivity around 88 - 90 dB ... I hope
I was thinking about soft dome 25 - 30 mm drivers.

In Italy Ciare speakers are largely used by Diyers but don't having direct experiencesand I don't know if I can trust their datasheet.

Some cheap options I found:
Audax HD100 D25

LPKH 100/25/145 FTF

Any help would be greatly appreciated

The right volume is the one you can live with and that gives enough of low end. I like what Ciare HT 263 tweeter offers.

I have larger speakers so "space" is not a problem. I just want the best / right box for that driver.
I was planning to build a 16 L box, a test box, and then reduce the volume to 12.

Also, i read somewhere that stuffing the box with cotton wool (once fiberglass) increase the volume seen by the driver.
Is it real ? And is there a way to predict the new box's volume?

I like what Ciare HT 263 tweeter offers.

I like it too, also is an Italian product so i'm tented of buying a pair.
