#3 - the CSS SDX12 (specifically the 12 - you'll see the displacement capability on the 10 is significantly less noteworthy).
EDIT: If the OP is modeling, it might even be interesting to model the SDX10 vs the SDX12 simultaneously just to illustrate why I say that.
I personally want this SDX12 bad. I'm an old-school XBL^2 fan, and I have a feeling this is the best one yet.
Plus I love how it looks like NOTHING, mounted. I used to assemble my prototype subs with the plainest dome dustcaps just like this, so it looked cheap and then I could surprise people.
Unfortunately I have a bit of a sub hoarding problem, and when I moved into my Fiancee's house and sold mine, I had to get a storage unit. That's a great price for a legitimate flagship sub, but I don't think it's going to fly with the lady of the house to pick up another sub. Especially when at least 3 of the ones I have in storage (and one in my little hoard-cabinet I keep at home) are XBL^2 already... not that she knows that.
Anyone else? Accidental collectors?

Do you mean the Scanspeak Discovery subwoofer vs the Revelator subwoofer?
Based on the specs alone, I probably wouldn't consider either for the price tags - even for a really truly purist SQ install, they have fairly "meh" capability:
Spec Revelator Discovery Price $640 $280 Fs 21hz 17hz Qts .26 .32 EBP EBP = 75, the woofer good for either closed or bass reflex. EBP = 50, the woofer is suited for sealed Xmax (linear - one way) 7.5mm 12.5mm RMS power 350w 150w Impedance 8 ohms 4 ohms
Based on the above, you would want to spend at least $1300 on two Revelators, if for no other reason than to get a reasonable 4 ohm impedance for car use. At that price, you could buy a 13W7, which I'm sure would be as clean (we'd need to see the Klippel curves for these Scanspeak subs - but the W7 has a very flat BL curve, due to the cross-drilling of the pole piece) and would be as loud as two Revelators - could be as loud as three Revelators, by virtue of linear excursion alone.
I'm sure it sounds great - but besides having a 21hz Fs (which any sub could have, either by running a heavier cone or softer suspension - both of which cause you to need a large box - I believe that's true here as well), all those specs are very middle-of-the-road... the price tag isn't justified.
The Discovery probably actually could be used in sealed or vented, the EBP calculates pretty middle of the road, and really is brought down because of the super low Fs. It seems to have plenty of motor strength (based on Qes) to stay pretty clean in a vented box... but again, pretty middle-of-the-road specs. If you only have 150w, it could be an efficient choice if you are willing to go with a bigger box - but again, nearly $300 you could buy something like that CSS SDX 12" for not much more, and that sub (with it's inherently flat XBL^2 BL curve, and I believe matching flat CMS suspension curve) will have less intermodulation distortion than either of these two subs, and has more than double the output capability (displacement) of the Discovery, and three times the output capacity of the Revelator.
I'm also not talking about "boom car" SPL - I'm thinking of it more like headroom. No reason to pay more and still end up with limits, these days.
I was speaking about the revelator sub. I'm looking at an application where I can do a single 10 in a stealthbox. Like a jl or nvx stealthbox.
I also need some semi shallow 10s for the front doors, and scanspeak offers those, so it seemed like a nice start. The more I think about it, the more it feels like throwing money at it, and maybe not getting the benefit of it vs some Dayton references or something else.
Just wanted to point out, Madisound's specs for the Revelator sub seem off. Scan-speak's own website for the 4-Ohm 32W lists xmax at +/- 14mm (One way). https://www.scan-speak.dk/product/32w-4878t00/
'18 VW Golf Sportwagen 4motion 6MT. Hiby RS6 to Helix DSP.3 (Balanced Analog). Amps: Biketronics BT4210 (210 x 4 mids/tweets), Biketronics BT3725 (250 x 2 midbasses, 700 x 1 sub). Mids: Satori MW13P-4 5" (Factory Door Locations). Tweets: Bliesma T25S-6 Silk-Dome 1" (Modded Factory A-Pillar Locations). Midbasses: Dayton Designer DSA175-8 6.5" in Ported Underseat Enclosures. Subs: 2 x Scanspeak Discovery 10" in Underfloor Sealed Enclosure.
I had a few to get this one modeled. I was kind of shocked that the 10 nearly matches the 12 in output but with a larger box. See also attached PDF for your review.
