I applied for a car loan, and didn't get it, so now I figure I'll blow all my money on a subwoofer instead. Its not like I need a car, I can't even drive. ANYWAY!!!!
I intend on ordering two Maelstroms, just as soon as I get my money back from a dodgy ebay purchase. Hey, while I'm here, why don't I tell my life story........ on the 14th of november, 1985 a child was both. That child was me. Weighing in at...... alright, enough.
I was thinking 300 litres a sub tuned to 20Hz... it should do 20Hz at over 120dB in room 🙂
now, what impedence are these subs?? as far as I can tell they are 6 ohms, correct? which means the amp I'm looking at will give them 500 watts each... plenty 🙂
anyway, is there a better bang for buck sub than the maelstrom? I thought about the Tempest, namely 4 of them, it would be slightly cheaper, and maybe even slightly louder, but I want 18's just so I have 18's 😛

You could look at Ascendant Audio's Avalanche 18 but I don't think it's suited for ported boxes 🤔 (but they would cost more w/amp cost)
Sit back and think about how big 2 ported maelstroms would be. 4 Tempests would be even bigger!(don't forget you need pretty big ports for 18's + lotsa bracing in such a huge box) . I have 2 sealed ~4.5 cu ft. boxes and they're the size of a big end table... bigger than I'd like really.
you're looking at 25-40 cu ft.! 😱
My 2 sealed 15s' that are no Avalanches is plenty loud for me...more than my mains can keep up with for sure... and the entire house rattles.
just my $.02

What about Aura NS18 18":
Expensive at USD$1100 but try an 18" with 17hz FS, Xmax of 16mm(a lot when you consider the radiating area) and a sensitivity of 90dB.
Luckily you'd only need one of these to kill yourself which is all well and good because you'd need to sell a kidney to afford two.
Or there's always the JL W7 13.5, again expensive but you should be afford two for the price of a single Aura. These have silly Xmax and will not only kill you but the house too.
An externally hosted image should be here but it was not working when we last tested it.

I guess you don't know the Maelstroms then....
13mm X-max.... 93db 1w/1m.... 20Hz fs.... and UAD$299
LOL!!!
I love my maelstrom but I'm not sure its the right driver for you because the primary response range in a ported enclosure is 50hz and down. This makes it an outstanding sub for HT. It sounds like you want to kill yourself with bass using music, so you are really looking for 30-80 or 100hz, not low teens to 50hz.
If you have room for 2 300L cabs, then basshorns is the way to go. You'll get much more sensitivity (easily in excess of 100/1w/1m) and can save money on a pair of suitable drivers. 18's would be totally unnecessary for a great pair of bass horns.

What about Bag End 18s?
I bought 4 off eBay, & cloned the sealed enclosure size and Linkwitz transform Bag End uses.
Flat from 8 Hz to 95 Hz.
Two of them are actually more than enough.
I built them to look like tables, with the woofers firing at the floor. Call the "Bag End Tables."

Bang for the buck nothing will touch one of Bill Fitzmaurices Tubas. Since you're talking big boxes, a Tuba36 (3 feet on a side, or 27cu ft) would do. This is along the lines of concert-level bass for ~300 person venues. The 36 (unlike some of the other tubas) reaches WAY down, too. Insane, irresponsible overkill for the home, but if you're talking about silly levels of bass, this will do it.

a 15hz basshorn... now that would be a MONSTER. 75 feet long plus a rediculisly large mouth. I dont think thats very practical

I guess you dont know the new 18" Maelstroms have 24mm Xmax one way. And the 18" Tumult is 34mm each way. Might as well wait for one of these or get the Avalanche 18.
According to the above website,
the Tuba 36 has a measured f3 of only 42 Hz.
Good bass, but is that low enough for a sub?
LabHorn goes down to 27 Hz.
4’ x 4’ x 2’ = 32 cubic feet.
The 15 Hz horn I mentioned is four times that size -- (8 x 8 x 2)...
Practical?
Whutz that mean???

Yes, the new Tumults from Chile come in 12, 15 and 18 inch diameters.
Here is what Dan said:
Tumult. Three inch diameter voice coil, XBL2 motor, 34mm one way Xmax. 12", 15", 18" sizes, dual 4s and dual 2s. Top of the line in output, great SQ.
These should be out soon.
While a 15hz horn is huge, building a bass horn as a bed or a couch is a way to fit one in the room.
Im glad your not actually suicidal but just insanely mad about bass,like many of us here are.
Id do a basshorn,which will provide typically 102db/1watt from 80hz-40hz where the response could dip down to ~97db such as a recent box i modeled which was for a shiva and 3metre path length. This way u save $ on drivers,using basshorns.
Then build one HUGE low tuned ported box for the 20hz effects. But really for music,20hzwhen its there wont sound much like music,and the low tuning will limit SPL giving you an HT style sound rather than percussive ouch my head aches kick
The big question: How much can you fit?
And regarding these super woofers with double Xmax than usual,and huge RMS ratings,my question is- how much more output results from this? Displacement is just SPL potential,the driver is still limited by its sensitivity,and the extra RMS rating is only usefull if the power compression isnt too high,and we dont know what it is 😛 + he Lives in australia so shipping costs will bump up the price of special one only woofers.

Well, you can't just look at F3. If you look at the outdoor chart, it drops at 42 but kinda plateaus down to 20, about 10dB down. I had assumed that anyone using a partial-size horn would use EQ since it's pretty much necessary. In this case, it becomes a question of efficiency and max output over the frequency range of interest.
For max low-end extension, you can look at the Tuba 36 as being ~93+dbW from ~20 on up, and will be power limited from ~25Hz up. This means 120dB+ from 25Hz up from a single cabinet w/ 300 or so watts.
The LAB is designed around clusters of 2 or 4 - you don't get much SPL at those low freqs out of a single cabinet. A single Lab won't outperform a Tuba 36 in terms of overall output (although it might be 'flatter' - I'm not sure).
A couple of the big high-xmax 15's or 18's in big crates will probably do better below 25Hz than the Tuba, but for a single-driver solution it's pretty tough to beat. The problem is the form-factor - a cube 3' per side is pretty tough to deal with unless you build it in. Bill has smaller units, but being real pro-sound oriented they don't get down as low - optimized for 40-100. Two of the still-in-progress T36 Slim units would work well and would be more manageable, but more $$$ and work as well.
Nope. My pair did low 20s with a smidge of EQ when pi spaced.Matttcattt said:
I'm moving so I sold the boxes and now I'm gonna use the drivers in an isobarik arrangement.
