The largest home woofer I'm aware of was the 30" Electro-Voice model 30W driver used in the EV Patrician. This driver was also sold under the University name. The driver was used by DIYers in rather large boxes; I once had enclosure plans from EV that included a 72 cubic foot box for the 30W.

Holy, moley, batman, those are huge!!!
The Hartley Concertmaster used a 24" woofer, made by Hartley (as were the upper bass and mid drivers) that used an odd enclosure. It was a large enclosure stuffed with fiberglass but with an acoustically open back covered by a screen. A friend had a pair and they had bass that was deep, clean and very powerful. Excellent speakers that few of the jaspers here talk about. Maybe they should have called the speaker the SX something or other, SX sells.
Anyway the big woofer was evidently underdamped as shown by it's enclosure and the success a fella in Speaker Builder magazine reported using one in an open baffle to augment his Quad ESLs.

A fast woofer is a tweeter.
Higher mass can be accelerated by a stronger motor and many large woofers have very powerful motors and excellent "power to weight" ratios that provide both excellent acceleration and damping. In any event in many uses a woofer need only respond to bass inputs; note that many large woofers aren't intended to respond to high enough frequencies where flex occurs.

Madisound has a 31.5" Fostex Super Woofer in their catalog for close to 4 large if interested lol.

Not sure if these are marketed for home use but they are big. Fostex offers a 30inch woofer for home use if I remember that correctly. The text is what I imagine is going on behind the scenes. I'm at work till Thursday and bored.
(Umm babe you said the speakers where only 8inchs)(they are sweetie, see in the center those are 8inchs)(dear this is not cool, it's our $&@"* living room)(buttercup do I give you crap about the 30 designer purses)(I don't keep my purses in the living room)(well maybe if I hadn't had to build the huge closet I'd have room for my own space, just please listen to them first before you judge)(I'm off to junior league, those 8inch SPEAKERS need to be out of our living room when I get back).
Mary Cathrine why are the kids outside, it's freezing out? Well we bought this house with the bonus room above the garage for the kids but Joel has managed to build some sort of radio, speakers, whatever, and now he won't let anyone go in there.
(Hey sweetheart there is dust all over the house and some guy from the heating and air place called, what's going on)?(Well I had to make some small changes upstairs in my room, I got a super deal on some speakers)(what are you changing)?(just cutting a few small places out of the wall and moving some ducts around, no big deal, it will be really cool when I'm done)(ok please try to keep the dust down)(I will snicklefritz, oh yeah there may be a few miscellaneous charges on the credit card, I'll take care of it with my bonus)(I thought we where taking the family skiing with your bonus)? (Did I say that)? (Yeah babe, you did).
(We need to talk)(what's up boobear)?(well the island in the kitchen has been unfinished for 6months but you seem to have time to spend up here)(Gosh boo I said I would finish it after I got this room finished up)(yeah well it's been six months and every weekend you have plenty of time to work in here)(just give me two more weeks and it should be all finished)(six months Dan, six months, I'm tired of it and there are plywood pieces all over the garage I can't even park in there anymore)(ok boo, I'll clean up the garage)(No Dan, finish the island, did you not hear anything I just said, the island, finish, that's it).
(Hey Farrel, the speakers sound great, can you make it to where I can play my phone through them)(sure honeybee, I thought we went over this)(yes well I tried and I can't make it work)(it's really easy you just push this button here about 20 minutes before you want to listen then make sure this knob is in this position, have the volume all the way down here, make sure the volume on your phone is here, push these two buttons here, then slowly turn the volume up but do not go past this point here).(forget it, I'll just get a Bluetooth speaker for the kitchen)(geeze honeybee I don't see how it can be any more simple).

Check the post right before yours, it's still available and actually 31.5".
I saw that, those where posted while I was writing my post. Thanks
I was referring to the OP asking about big cabinets. I just posted big speakers. I would love to hear anyone of those set ups.

After all the post relating to wife friendly speakers, I thought the dialogue was funny referring to the pictures of the huge setups. They are imaginary conversations between the wives and fellows who own the huge systems. I could have written it like a script, that would have taken two pages. Sorry about the lack of spacing and punctuation. I wasn't trying to highjack the post, the OP asked about really big speakers so I assumed it related to the content in a funny way. Just like speakers, humor is subjective opinion.

I can't find the URL currently, but there's a guy out there who's a real organ music enthusiast. He was unhappy with the bass produced by his Infinity IRSes (6 12" servo-controlled woofers per channel) so he sold those and built his own DIY wall using 3 30" EV woofer (plus some other drivers) per channel.
Below is a pic with his wife standing in front, but if you can find the original page, it's an interesting read.
