I have seen sp200x suggested for open baffle (as a lower price alternative to the Visaton B200), but Qts=0,52 might be on the low side for OB.
Why not tell us what you would like to improve, and a photo or plans of the existing cabinets. If the cabinets are worth keeping, it may be possible to modify the cabinet to some TQWT or TL alignment.

Hello,
I've got four of them and there are several options:
BR - from 50 Liter till a 100 (more liter the beter, I'm thinking of 70Liter would be nice)
TQWT (Tampered line) If you need the scetches I've got some images from an old forum that isn't around anymore. They should sound great with a deep bass and aren't as big as the 100Liter BR's...
Double BR (As the Visaton Solo 50 and 100)
Open baffle, not my favourite tried it once...
Horn, haven't tried it yet.
In short I'm going to build the BR-70Liter with them and a TQWT just for fun... But first I'm going to finish some old projects I've got lying around.
The SP-200x needs notchfilters, you'd best should use 1.5Mh, 2x22Ohm 10Watt, 2.2uF in parallel of each other in a serie on the SP200x.
In addition a supertweeter would be a good idea to get some high out of the speaker... with a 8.2Ohm resistor in parallel and a 1.5uF 400Vdc in series of the tweeter.
Hope this helps, Gr. Henri

my 5 cents...
Hi,
Here is a TQWT drawing, from a french forum :
http://www.cinetson.org/phpBB2/viewtopic.php?t=8512
Note they add a SPM-90, glued at the back of the driver, to increase the HF :

To be glued as opposite field, preferably whith a 3 mm spacer...

Hmmm That TQWT looks like the speakers I have. I thought it was a folded voigt pipe
But I dont have that filter and I have to look at my draving about the size of the cabinet.

If you can afford big dimensions, the BIB is just for you :
http://www.zillaspeak.com/bib-howtobuild.asp
http://www.zillaspeak.com/bib-pics.asp
http://www.zillaspeak.com/BIB-Monacor.asp
It will be about 178 x 42 x 29 cm external...

veryy intresting. and easy to bild. The cabinets I have look like this http://melhuish.org/audio/DIYTQ3.html
And They are 100cm high. 20cm width and 40cm deep.
If I build BIB with sp200x. Should I use some kind of filter?

Hi Tyor,
here is also an interesting project http://www.troelsgravesen.dk/SP200.htm
I use the SP-200X in the following setup:
6AS7G tube amp, notch filter from troelsgravesen, zobel for impedance linearisation and a ca.70liter vented enclosure.
I use the Fostex FF85k as a supertweeter with 2,2µF. I had them laying around and for me it turned out to be the perfect match.
So have fun with the drivers.
