After looking through diycable.com, I came across the Exodus Maelstrom line subwoofers. I am getting the Ex-Anarchys and when I saw the 21" monster I did some investigating. I have seen that it is apparently a beast of a home theater sub so I thought I would run an idea by you guys. How about two of these in a 20 ft.^3 box tuned to somewhere in the neighborhood of 24Hz? I was thinking maybe a couple of sundowns, 2500ds or 3500ds, or something like that to run them. I would be looking for absurd low end response, and I know it's not a SPL sub by any means, but what kind of output would that yield? This is just an idea and I am not even sure about going through with a new sub stage right now but I think this would be a cool goal if you think it would be worth it.

Other ways to get what you want in a car. I'd also bet you don't need anything tuned that low.

This wouldn't be to go along with any sort of set up. I eventually want to try and get some ridiculous low end output. What would be another design or group of subs that I could use for this. BTLs, Qs, Cs-18s, lms-ultras, XXXs... Should I go sealed considering I really am looking for increased output from about 18 to 30 Hz with low distortion. This would just be a project for fun and sometime in the future.

What are you going to be playing that hits that low besides a test tone.

Get you some XCONS and tune to 26hz if you want. They will hurt you on the low end.

Test tones, I have 4 ed 13av.2s right now tuned to 28 Hz and its not quite low enough, for a decent response in music its fine, but I would want to do this just as an experiment, then maybe use whatever I use as some HT subs. Would xcons work better than what I have now and would they double as HT, haven't seen them used for that.

Have you seen this build?

Team Decent "Punisher" Build - SSA Car Audio Forum - Page 5

XCONS little brothers putting up a 151.2@25hz and they are still tuning.

I would ask SSA about HT, but I see no reason why they would not kick ass.

Would it be necessary to do a wall? I wouldn't mind trying a few of the xcon 18s though. What kind of box space do they like, if they are tuned around 26 or so.

Test tones

You want to spend a G plus to play test tones? To each their own I guess. I wish I had your money.

Whoops, meant to say music. That's kind of a big typo haha.

Hmm, then I'd ask the same question Lancelot did.

AWESOME idea. It's sure not for everyone. I made sure to reply to your OP before reading ahead, cuz I won't be surprised if I see some hate

Maelstrom-X is the best of the best for low end/wide/flat responce IMHO. Adire Audio RIP... The Tumult and Brahma were cherry. RE and AA doing the XXX and Avalanche. Those were the days. XBL^2! Low Fs, high Xmax, low inductance. Not for your average car guys who dont generally care about Xmax, Inductance, Fs.

Tuning so low? Thats another argument in itself. Seems 32/33Hz is the "magik number" for the bottom. Anything lower and people start getting skeptical. Well, 99% of the people that flame on tuning 25 or below have little to no experience tuning that low and listening to music. You can play with Audacity all day and tell me 99% of music won't go below 30Hz, and I say well you don't know where I'm coming from and where I'm going

They're expensive. $550-$650 a pop...depending. I was setting up a deal to get 12 Anarchy's and 6 MX21's. Kevin wouldn't do the 2 anarchy free per 21 purchased on all 6, only on the 1st one. If he would have, I had the money in paypal just waiting for him. IDK if he's even sold much more than 6 since he released them!

If youre looking for 18Hz-30Hz, tuning to 15Hz- 23Hz would be your ticket. Youre generally solid at leats 5Hz below tuning in-home with room gain. In car you get more gain, cabi gain, so your 24Hz would be sweet. Why waste the rear output from the driver? If you're looking for flat responce this isn't the way to go...then sealed is... or a higher tuing... but if you're looking for exaggerated sub 30Hz material, port it. If you tuned too low, the box acts likem a sealed box once you get above the frequencies where your port helps anyway.

a lot more than people think

I might just have to stick with the XCONs then for my next build like you said on your thread, and whenever I can put a little money out there, I will try the low tuning idea. I think I really did want to go for the cool factor... well the cool "feeling" factor. Those low test tones and some songs just have that unexplainable feeling I love, but it never moves as much air that I would like it to move. May not be the best musically and I know that, never argued that point lol. But thanks for the support and I will be sure to let you know if I ever go forth with it.
