Hey Guys,
i've got 2 ScanSpeak 26W 4558 and am looking for the right enclosure.
The Setup:
2x Vifa 6/1 Coax as Tops.
A Sure/Wondom DSP + Amps + the possibility to measure some room dependencies with a superlux mic (for the finish 😉
Usage is Music (all kinds of).
Now the ScanSpeak Sub seems to be made for rather small enclosures. I could give each of the drivers up to 75L. I'm more a fan of CB Systems, but this maybe a more psychological thing. I'm aware of the possibility to use the passive radiator (like troels gravesen did 😉 but i have to opt out that idea, because of the aesthetics. The Subs should look like a scaled up version of the tops. Only one chassis on the front, and a size like: height 60 width 30 depth 40 (just that you get an idea).
Can you guys help me, finding some good solutions for two enclosures in between 50-80 litres, cb or if it is much better br.. ?
Thank you guys in advance. Any informations are appreciated!

Greets!
75 L net = ~0.5 Qtc, Fc = ~32 Hz, F3 ~50 Hz per this math, so tell us if it's good enough 😉: https://www.ajdesigner.com/phpsubwooferclosed/constant_equation.php#ajscroll

that 60cm high, 30 wide and 40 deep (so 54L) sealed should work for one driver with an F3 of 39 and more important for sealed, an F6 of 30Hz. QTC is 0.7 which is almost the prefect alignment. This will work the best against or close to a wall like most sealed cabinets.
You should brace this box firmly, as the internal pressure will be rather high on high volume, but as it's a sealed, a bit loss of volume does not matter that much. And if you put aquedate damping inside, that damping will make up for that volume loss. So use enough bracing all over the box.
