40 hz too high?

[needmobass 0]

lol.OP, You do what ever you want. To all you guys that have replied to this post, thank you for tring to educate this guy. 18s do suck ...so do 15s,12s,10s,and 8s, we should all go back to using 6x9s. Think about it a wall of 6x9s doing a huge 120dbs

[Budah93 7]

i'm not saying you guys dont know what your talking about i'm just saying what makes you any different than any other guys i talk to? like you are completely bashing them and you all are convinced that your opinions are the best. so what i'm not a big fan of 18s doesn't mean i hate them. yes i said they sucked from the experience i have i really was not impressed. will i get 18s in the future? possibly. i'm sorry if i offended you buy common now. you guys are no different then people i talk to at spl comps. you both run your own systems and have your own opinions

[Budah93 7]

also i have taken the knowledge you guys have given me and i will use it to my advantage.

[StreetLegal 119]

Ok guys lets all be friends here...

[ssh 924]

I didn't "bash" anyone-only pointed out false information that anyone with a relatively intermediate understanding of speakers would laugh their ass off at.

Now if you want to hear bashing: I find it incredibly amusing that one might think of themselves as knowledgeable in the car audio realm, yet don't know what either a Low Pass Filter and Sub Sonic Filter / High Pass Filter are, or how to set them.

I don't have any credentials, so you can choose to take what I say with a grain of salt. In fact I believe you shouldn't just listen to my bashing, but instead research for yourself. Maybe read a book on the fundamentals of speakers and enclosure design?

[Budah93 7]

I know what lpf and the ss are. I typed my number for the lpf wrong it wasnt that high. I just want slamming lows and didn't know if re tuning those would help

Because it's not a matter of opinion, it's a matter of fact. Our "opinion" is based on the physics involved. Your friends "opinion" is based on the nothing but misconceptions and untruths. That's what makes our statements (which are not opinions) different from the opinions you've heard, and what makes our statements (not opinions) more qualified than your friends and yes, more accurate as well. If you understood the physics involved you would understand why your friends "opinion" and the information you were given by them is flat out wrong. And yes, apparently our statements are significantly different than the people you've talked to as our statements are based on physics and facts and theirs simply are based on nothing but misguided and ill-informed opinions.

Take any subjective experience you've had with 18" subwoofers and throw them out the window as they don't mean a thing. Seriously.

[Aaron Clinton 2,372]

I know a good amount about audio and understand enclosure makes the system. i'm just saying i've been advised from people on this very site to go with 15's instead of 18s and i think with the proper box built i could run 18's the subs just couldn't be right next to each other they would have to be diagonal from each other...unless that's bad for them some how

Can you please link me to where this false information was posted on my site?

[Aaron Clinton 2,372]

so 18s really aren't that bad??

If you could sit in NEM's 4Runner, it would change your POV.

[Notorious97200 339]

OP, one thing I can tell you : those guys know their sh** ! No joke business !

It's hard to beleive some memberS, HERE, told you 18's were bad !!! Maybe you did not have enough room for what you wanted !

If you want more bass & low notes, run more subs or larger ones (in the appropriate enclosure), tune around 30 Hz,...

Good luck !

[Aaron Clinton 2,372]

i'm not saying you guys dont know what your talking about i'm just saying what makes you any different than any other guys i talk to?

The advantage you have by coming to the SSA forums is;

~ massive amount of experience in practical and impractical applications

~ talking directly to industry or industry related professionals that actually have more experience then pointing to a picture in a Chinese catalog

~ scholastic and professional usage and understanding on a very precise level

~ almost distorted level of actual topical and applicable knowledge over other forums

I could go on, but I would embarrass other sites more then I already am. Essentially when you have someone like Sean (///M5 an engineer with a background in acoustics and physics BTW), Mike (95Honda who has built just about everything you can imagine and then some over 2 decades), Brad (Impious who has has a far more elevated understanding of the science and design that goes into a speaker then just about anyone), shizzon (very well traveled SPL competitor/enclosure designer), Ricksi (talented enclosure designer and builder), bassaholic (Drew, a young but accomplished SPL competitor), etc, etc. etc. could keep going, ALL in the same topic trying to help out, I think it might be worth a moment to listen. Don't mind me, I just co-own a sub woofer brand.

[Budah93 7]

so do guys think i could fit 18's with these max dimensions. if so how how would i design the box.

36 width, 27 depth, 23.75 height

[Budah93 7]

you guys changed my view haha I think i'm going to get 18s. How are the ssa icons? I wanna make sure whatever i get is an upgrade from my sundowns. I watched some vids and read some other forums and 18s seem like they would be bad ass

[nem 2,019]

I know I sure love the sound!

I would not decide on any sub or size until you knew for sure you have the needed room and power to have it perform properly. Another big question is "am I willing to give up that space for speakers?"

[bassahaulic 155]

We were not trying to force you to run 18"s, simply saying that they can/do sound just as good as any other speaker.

Based upon your measurements, you can much more easily fit 15"s, since you only have 36" wide.

I would highly recommend SSA speakers though, they have exceptional build quality, power handling, and response.

And thank you for the compliment Aaron.

[Budah93 7]

would it be bad to put the subs like this?

Sub Here

Sub Here

I could fit them like that and could build a box around 12 cubes before displacement

[ssh 924]

You would have to angle the mounting baffles inward or outward.

When I quote your post it shows you as having them be staggered...here is a quick mock up I did, is this what you're thinking?

EDIT: Keep in mind this was a real quick mock up I did it's not an actual design...the port would look much different. If you looked up the specs on the box it would probably be tuned in the 50's and be like a burp box

Edited August 9, 2012 by Kangaroux

[ssh 924]

He doesn't have anywhere as much space as that above top mount baffle, but if you did stagger them, it's going to be extremely close. I believe the outside diameter of the 18" ssa icons is 18.5"

[Kangaroux 47]

That was for his sa-15's in that design. If he wants to do 18's he'll have to stagger and do a port on the bottom of the box. Unless he can do a step up enclosure because I assume his vehicle is like mine and has wheel wells that stick out a lot and shrink down your box width by a lot.

[Budah93 7]

Yea the wheel wells screw me. I really don't think I could fit 2 18s in there with any design. I think if i do upgrade i would have to get different 15s

[Budah93 7]

guy fit 18s in his blazer and i don't know how. I have a maximum of like 37 width and he has space between his. how does that work??

[S.DeYoung 968]

over the wheel wells?

[Budah93 7]

possibly, he might have just cut out part of the box so it rests on the wells. i'm too lazy to do that haha i'll just upgrade 15s, probably gonna go with death rows or xcons. Both of those would be upgrades from my sundowns right??
