thinking of getting a atlas sub from ascendant audio and was wondering which one i should get. im more of a sql person. i wanted to know which sub would probably distort more than the other. also should i do ported or sealed?

 

I like 12 in subs beacuase there more accurate then a 15 is .. 15s are sloppy ... 12s dont drop as low but how much do u really need? depends.. on what ur lookin to do and how much room u got to use .. also think about weight too...

 

12 bye far. as he said 15's get really sloppy and they take up way too much room. but what do you mean by sql?

 

i got two (and i know your all going to rat at me for it), two audiobahn AWES12P's and there just fine, now ive heird the AWES15P's before and like said before 15 are just to sloppy, there just ground pounders... Go 12's

 

I hope there is no generalization in here about 15s being sloppy....

get the 15" if you have space. '


While both of them are able to get loud while still sounding good, the 15" gives you more headroom in terms of displacement. Not to mention, its only $5 more for the 15".


sealed vs. ported, depends how much space you're willing to give up.

i have a 93 accord and would think that the 15 would fit, but only thing im really worried about it the weight of the box and sub. also i have to take into consideration on what amp to use. yeah $5 more seem like a good deal thats why im having such a hard time deciding, i dont wanna pass up on this deal.

 

go for the 15".

The weight of the subs are not that much different. probably 5lbs at most, if even.


If you want to save weight, definitely try Baltic Birch. The birch is much lighter than MDF of the equivalent thickness. Its also more rigid than MDF. What you might get more noticable resonance, but I don't thik you'll have much of a problem with that.

more like how much sound quality. if it isnt a high output sub, never slap it in a sealed box, you loose way too much sound quality. and think about it, theres a reason the 15 only costs 5 dollars more... one other thing i would like to point out is my 12" polk/momo i believe weighs around 32, i believe alittle more, but divide 12/32 thats 3.75lbs per inch for my sub, if i added 3 inches that would be 11.25 more lbs if i had a 15. atleast. not saying that is exactly how it is, or how it would be, but i doubt its only going to be a 5lb differance. and everything i have said is IMO to me a 15 is one of the dumbest things around, cause nothing but rattles, 97% are inaccurate, take up too much space, pointless when yuo can get a good 12 that can hit alot of the same notes and go louded, hit quicker and be more accurate

??? sealed box will have a flatter frequency response. You gain transient response with a sealed box over a ported box. The group delay is minimized. I fail you see where you lose sound quality.

Because Ascendant audio is switching topologies on their sub and would like to get rid of their altas as soon as possible. It has nothing to do with the quality of the driver. They priced it around the same price as the 12" so the demand would be equal.

I've weighed both the 12" and the 15" atlas. They are within 5lbs of each other. The basket/cone/spider do not make up a lot of weight when upgrading the size of the driver. Now if the 15" and 12" uses different motors, then it could possible be more than 5lbs.

There is such thing as a volume ****. I know 10" that will get louder than a lot of 15". Just because you have a 15" doesn't mean you have to crank it up all the time. If anything, 15" are more accurate since the are able to play the lower octaves better than their smaller 12" and 10" counterparts. Linear displacement is leaned towards the 15". Once you're out of the linear range of the 12", the 15" still has headroom. Going out of the linear range will increase distortion levels to over 10% THD. There are a lot of 15" subwoofers that will take up only 1.5 cubic feet sealed. Thats is a very small box for a 15" subwoofer.

12's are not quicker. You only think its quicker because the lower end magnitude is not quite as high as the 15". The general consumer will believe bass is quick, only to find out its not really subbass that makes it sound "quick", rather its the midbass frequencies. Subwoofers shouldn't play midbass if your top priority is sound quality.

There are plenty of top competitors that uses 15" (and in some cases, dual 18") for the IASCA event and has won one of the top places in the nation. Tuning abilities will go a long way, rather than just sticking it in a random box and calling it a day. I think thats where all the bad crap about 15" started from. People just don't know how to make use of it.

yeah, open mouth insert foot. meant ported box.

that deffinatly has alot to do with it, but i still dont like many of the 15" ive heard. and other than that im not willing to risk themoney to just try one at this point. as of now i will stick with what works for me and what i know works. as ive said and will say once again, all of this is IMO. not trying to cut on subs or anything, just giving my feedback. good info though

 

you should try one of the higher end 15". None of the stuff you get from best buy or circuit city will cut it. Try the ascendant audio atlas. They sound just like the 12", but able to extend down to a lower freq without a problem.


Or try to find someone with a 15" Adire Audio brahma or something of that nature. Very accurate subwoofers, even at loud volume. I had my fair share of 15" and i'm currently running a 12". Would have ran a 15", but image dynamics doesn't make a 15" IDMAX

 

GSteg what sub would be better the ascendant audio atlas or a alpine type r?

 

the atlas would dwarf the alpine type Rs. the altas are simply on a different league, in terms of output, distortion, etc.

Overal, the atlas are better than the type Rs if you're looking for low distortion with a tremendous amount of output.

 

12

 

thanks gsteg for all your help. in the end i ordered the 15'

 

let us know how it goes!


what kind of box are you putting it in?

God I hate it when people hear one thing from one person and spread the lie.
15s are just as accurate as a 10,its all in the setup and speaker choice.I'm sure you too get annoyed defending 15s.My Resonant Engineering XXX 15 sounds awesome the SQ is superb,and gets crazy loud.So once again..... a good 15 IS NOT SLOPPY.

So yes go with the 15 you'll love it,I've heard nothin but good things about Ascendent Audio.good luck,keep us updated.

Sorry to throw this off topic but just wondering what amp you are using with that xxx. Im thinking of ordering one here soon and ill be using and autotech meanmachine mx1300. just wondering who that might compare to what you use?

 

im kinda gradually in the process of building my system. i wont be testing it until like couple more months or even a year.

 

u seem to be like me. i've had a lot of my stuff for over a year and just finally got off my butt to install them. lol

Right now I have a Planet Audio 1400(1200watts),i'm about to get a Orion 2500 and just break ****.Anything around 1000-1500 will get that thing slamming,600-800 will be nice too if you can't get a big amp.That autotech should be more than enough.Good luck any other question just PM me.

 

what amp should i get to power this sub?

 

It looks like that 15 Avalanche can take a bit,what kinda price do you have to work ?
