Most cheap low xmax 15" even with stamped steel frames are over 100$ here now, I can probably get some cast frame 6mm xmax Fane Sovereign Pro 15-600 for 135$ + taxes.
The end-of-line Beyma 15MC700 are still 230$ before taxes and shipping, looking like a steal compared to some other things.
Anything with good xmax AND cast frame is getting really expensive.
Cheaper to get some half decent 18" these days, B&C 18RBX100 is looking like a viable option, very tempting to get some SB Audience Bianco-18SW450 though I am not sure what kind of box to make for those.
12"s completely unsuitable for bass are catching up with moderately expensive 15"s from the same time last year, or even cheap 18"s like the previously mentioned 18SW450.
The US of Ay does not seem to be affected to the same degree just yet, maybe later this year.
Conclusion:
Been trying to look at Beyma, Faital, Mica, 18Sound +++
So far it seems like the most displacement per buck is the SB Audience Bianco-18SW450 at 123 Euro, any contenders?

Hi,
yeah prices creeping up!
Sheet of 15mm BB ply seems to be ~130e here so significant cost factor if looking for cheapest possible solution. Thats ~40e/m2, 18mm thick costs ~50e/m2
If one has 1kW amplifier available already without extra cost, then a woofer that can take full power thermally and consume half ply for the box than a low power handling woofer in a huge box, for same volume displacement. Well, also amplifier power costs so... 😀
Questimate need of ply from Vas and assume cube enclosure:
6 * ( cubicroot(Vas) / 10 )^2
Multiply with price per square meter or perhaps just check out if one or two sheets is required or something like that 🙂

That is a good idea, though it would take some work to incorporate and sort those suitable for vented and those that are better suited for closed boxes.
I really like closed boxes, but vented enclosures have their advantages, when battling for output vs cost cheaper lower xmax drivers in a vented enclosure may beat a higher xmax driver easily.
In this example the cheap double 12" outperforms the higher xmax 18" by a fair amount, I estimate cost of enclosure to be similar because the 18" would require more heavy materials and bracing since the energy has no way to escape. Amplifier costs would be about the same.
Edit:
I had to use EQ to get more low frequency output and pad down a significant hump from the 18" centered around 60-70Hz somewhere, gentle sloping is okay, big hump is a no-no.
Hi,
It could be nice to have something like that ( spreadsheet).
Isn't it what Patrick Bateman did around 2015? He came to conclusion Alpine 15" was best buy at that time iirc.
I'm ready to help with that but i think we should define how to display the info/ have a template.

I like the idea to have sealed/vented (even other options) but i think it's not going to be easy: a linkwitz transform could make almost any driver suitable for sealed ( with limitations of course...).
