Hey there everyone.
Well, if you've seen my thread in the loudspeakers section you'd know that I'm a huge fan of big speakers and if you haven't seen it go take a look , the post only starting getting really good at the page I put this link up for. We are still in the process of finishing the plans. But I've git the basic driver selection picked out and an approximate figure as to what they will be capable of when they are finished.
Well if you didn't click the link here's my driver selection
4 Dayton 18" pro woofers
2 Beta 12LTA 12" Mids
and two HF drivers with waveguides .
That's 2 woofers, 1 mid and 1 horn loaded tweeter in each cabinet.
Well, to the point, does anyone know of anyone sub woofers that will be able to keep up with these beasts that are currently being prepared for construction.
Yes, the 4 18" woofers will create an extraordinary amount of bass on their own tuned somewhere near 32 Hz, but I want to eventually get a sub woofer that will cover the super low frequencies without blowing my wallet to shreds. It'll need to be somewhere around the $1000 range.
Can it be possible that there's something out there that's made just to cope with heavyweights like mine?

How many drivers do you want? How many watts are you planning on pushing to these subs? What impedance are you looking for (4ohm or 8ohm total?)
You're talking about 120+ db at 40 hz, and you want to keep up below that?
It can be done- but it's not cheap. Search for "infinite baffle" subs (your dad would love that!) and sonosubs. To keep up with that SPL, you're looking at $1000 in drivers. Four long-excursion 15" drivers should be able to do it in large ported boxes (thing sonotube), and these are about $250 each. The Soundsplinter RL-P-15 is probably the most popular driver for that now.
You'd be looking at a minimum of $400 in amplification; a big pro-sound amplifier would get you the best power for your dollar. A lot of people are using the Behring EP1500 for bass duty.
Your other option is to build the Royal Device

The amount actual amount of drivers and watts and all that don't really matter to me. As long as it can keep up with my speakers.
Of course I won't be constantly blasting them but it'd be nice to keep a below 40Hz frequency@120+ db's. As long as it can hold it's own.

Well, what exactly is the infinite baffle theory, it seems to have something to do with putting multiple drivers in the same enclosure.
Use them without sub at first - it is most likely that other things than your wallet will be blown to shreds ! 😉 😀

The question in my mind is ...do you even have any full range speakers yet.
From looking at your other thread there has been a lot of talk on your part with little sinking in.
If you don't have any "main" speakers yet then its foolish to bother the forum with something that could change a 100 times before you get around to buying or putting something together.
What will keep up with the monsters that you don't have yet? Hummmm, about anything you could imagine I suppose.

Yes, it seems subs are a relatively new idea designed to help small speakers in producing the full range. Understandable in home theatre with so many speakers, and in cars where space is short.
The way to do it right, IMO, is to build your stereo speakers full range so they don't need subs.

In this context infinite baffle means that the drivers are mounted in a wall/floor/ceiling open to another large area. From the den to your garage for instance. Reported to be very clean and natural sounding. The catch is with no box loading they typically need lots of EQ to get flat response.
Lots of cone area is required to go low and loud. If you're trying to get down into the dinosaur footfalls area at 120 dB, plan on at least four 18" drivers, more likely 8. Double that for 15s.
I think you'd need to increase your budget by at least 3x to get 120 dB in a reasonably sized room at say 12 Hz. If you limit your quest to 20 Hz and can accept a fair amount of distortion, you are getting closer to your budget.
I run a pair of JBL2245H (obsolete) 18" subs in a 20 x 25 x 8 room that gets me around 104 dB at 22 Hz. on 500W. That's plenty for me. Since you're looking for 120 dB, that's around 60x the acoustic power and most subs that go low are not particularly efficient...
If I understand you music preferrences I think you will do fine to just EQ your monsters. I don't think you will need a sub. If you do want a sub though a pair of Dayton IB 15" in a really huge TL should get you close to 120 dB at 15Hz. But really don't persue this until your monsters are up and running.

A few observation:
Your selection of drivers doesn't make much sense to me. I think you'd be better served with a few good drivers, rather than a bunch of low quality ones. The Dayton 18"s look like a waste of money. An 18" driver with a 6 pound magnet looks about as useful as fins on a Cadillac. I suspect the 18"/12"/tweet combo is going to sound awful, regardless of the enclosure. You'll just end up with a boomy sounding set of speakers that don't have either bass or mid-range.
If you want something that will sound great and crack the sheetrock in your house I suggest following Bob Ellis' lead. Get a pair of JBL 2245H drivers and build B480 type cabinets. Then build a pair of cabinets with a high quality 12" woofer (JBL 123A-1), 6" mid (JBL LE5-2), and a UHF driver (JBL 2405). Obviously I'm a big JBL fan. For the most part, the drivers I've listed can be found used on ebay and will put to shame 99.9% of the new drivers you'd otherwise consider.
The JBL 2245H is just about the pinnacle of low freq drivers. You'll be able to feel the notes you can't hear.

36" tuba HT maybe?

Try 2 for stereo in the corners, should keep up.

If you can live with big, how about a sub bass horn? I came up with a design that I'd build if I had the time/space. It fired into a corner, was the width of a good sized HT screen and ran floor to ceiling. It only projects half a metre into the room. With a pair of 12" sub drivers with sufficient excursion, it can do 120db @ 20 Hz in its sleep. Actually its not far from 140db with only a few hundred watts. It is fussy about placement as the corner becomes an important part of its design, and probably doesn't easily fit in with your existing boxes.
I tried to wade through your other threads but left wondering what exactly you have settled on for your mains.
