15" XXX or ???

[LiquidClen 10+ year member]

I'm debating either throwing an IA20.1 on a 15" XXX or getting 4 10" subs, but I'm having trouble deciding what I should get. I previously had 2 12" Arc Flatlines off ~1600W, but it wasn't loud enough for me. Do you guys have any suggestions? I'll probably have 6-8 cubes to work with ported. Thanks guys.

the 05 xxx is a badass driver no doubt. its an unreal low end monster. and its the only sub that im willing to call a low end monster. other subs that i have heard that were called this by other people, just were not even close to the xxx. you sacrifice upper freqs though. not that they arent loud, they jsut roll off quickly. im sure you can improve it with box design, but it seems to be an issue you jsut have to live with considering everyone agrees on this aspect.

i would go for 2 12" xxx's or 2 12" fi Q's. shawn flemming said his dads Q's were louder and didnt sacrifice the highend like the xxx's. but he said it took them 3 weeks to break in and do this. at first he said he didnt like them. i still doubt that the q's can keep up with the xxx's lowend though.

2 12"s are so common place though, I kind of want to mix things up. You wouldn't suggest 4 10" Q's? My midbass is a pair of 8" Dayton Rs225's for anyone who was wondering...

One on one It's hard to tell which is louder, but his Dad's explorer w/ the Qs was VERY loud, and definitely had no issues w/ the low end...though I never got to hear it with the XXX 15s, I am however using one that came out of it. You're right though, the XXX has a very quick roll off on anything above 60-65hz, it's unfortunate that a driver like this has a flaw so apparent...even with my front stage it's still noticeable.

I'd wait to see parkave review on the DD clone and get those if they work. VERY cheap, and you could run a few 15's for the price of one XXX.

If you don't know what I'm talking about search Konaki or cheap DD in the search //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Just because someone is making a cheap DD 9500 knock off does not mean its a good fit for every application. If this guy was building a budget SPL rig, Id agree with you. But, he's not.
The original XXX does not go above 60-65 hz well, but technically a subwoofer shouldn't have to. Im setting up dual 8" midbasses in each door to help blend my XXX's to my front stage.

yea i figured i would just use that since thats what he claims. i have no reason to doubt him so i use that as an example for people that are wondering.

i agree with audioholic, but you as well. the subwoofer shouldnt really have to play the upper freq, but most end users will consider this a flaw because we always want perfection, and if we notice this little smidge, then we see it as a negative. i gotta admit, i loved my friends XXX but i still saw the fact that it rolled off real quickly a negative. its really going to be a personal preference, as well as taking into account how much midbass you have to try to back you up.

liquidclen: i couldnt honestly give you a suggestion as they are all opinions. i havnt used the q's so i can really only go by what i have read //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif. not to mention that i have never used any 10's.

True, it shouldn't have to, however, even with my front stage the roll off is definitely noticeable. The doors in my VW are rock solid, plus the two layers of RAMMatt on each panel helps, and they play cleanly down to 50hz with a decent amount of output for what they are, but they still can't fill that gap the xxx leaves out.

Though if all you listen to is rap music or similar, you could probably get away with it. But seeing how I don't, it's apparent pretty much all the time //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Im confused, you play your fronts down to 50hz and still notice a gap in freq response? A XXX will extend to 50hz no problem.
I ran one of my xxx's sealed mated with adire koda's (6.5's) and 99 out of 100 people didn't/wouldn't notice the gap. And I rarely listen to rap. *shrug* I never got around to sticking my RTA on it to see exactly what was going on. I will after I get them re-installed in the upgraded system.

Yeah, money definitely isn't the issue. I was hoping to get whatever subs I use to extend to about 80hz, because i don't think it will be super easy to blend a sub off 2kw into my front stage...

Yea 50 or 63 can't remember, then the sub is crossed at 80hz w/ a 36db slope. It's not bad, but I notice it, only because I didn't have a sub for about 6 months, and when I finally got it installed, certain songs I was hoping for some more umph from certain bass guitar passages, and it's just not there.

I agree with you, but his original post did not really specify much more than a 15 or 4 10's. My thought was that he was looking for output, not a freq. range to match. From what I have gathered, I he was looking for out of the ordinary. In that case, go with 3 15's //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif//content.invisioncic.com/y282845/emoticons/drool.gif.b5e863e893038027711d4402f340dad0.gif

If output was the goal, and no budget is specified, I'd wait for the pending forum boner.

Now if quality sound is what you are looking for....actually, i'm not going to guess...what EXACLTY are you looking for (to the OP)? Output, SQ, SQL, SPL?
