I'm going to be running 2200 rms to two 18 Inch Q's. Think I can keep them both straight stock? Or should I pay for a couple upgrades?

They have been busy lately and seems that it has really gone by the wayside.

Well I think i've talked him into understanding that what he really wants is to get loud lol. So Id imagine he is going to go with Bl's eventually because they fit his budget best out of the btl and xcons. (needs four 15's, 4,000 watts to work with, 20 cuft to work with)

Well, I guess what im trying to say is, in the context that I was referring to, yes, you would be underpowering the subs. Not that it matters at all, but to save some cash it does.

Eh I've ran em and they are good but too expensive for him. Plus they are 1750 rms, would be a waste then for four - not enough power. Also they are more """SQL""", so I bet btl's or maybe even the bl's would get louder. (Not that the xcons dont get loud) No such thing as ""SQL"" or underpowering a subwoofer. siigghhhhhhhhhhhhhhhhhhhh. 1: okay, its a sq sub that has a 1750 rms rating. 2: why should he pay more for a setup of subs that would have 3000 watts worth of headroom when the bl's would be cheaper and land right at the amount of power he has?

lol well for now he's just chillen on the idea until he finishes getting his cash together. haste makes waste ya know I do think he's been looken at the SSD line too, someone told him to check it out lol. I told him that BL > SSD of course. But he's talkn about four ssd 18's now haha I'm pretty sure I've talked him out of the Q's tho. Seems down to BL's, maybe SSD's, or he was thinking maybe just two BTL's lmao. So not sure if eliminating the Q's made it easier haha

Patience? I think 9 business days for a hat and T-shirt is patience..... Easy now! Wouldn't want you to get your panties all bunched up! IMO, 9 business days without any sort of contact about shipment, something is wrong. Shouldn't take that long. Ive sold hundreds of things on ebay and thousands elsewhere, if you dont communicate with your buyer within a business week, they deserve to know what is up.

Email doesn't even remotely work. I've tried emailing them a few times with questions over the last year or so and never got a single reply to any of em.

So, there isn't that much of a startling difference between the lower FS and much higher xmax of the Q's? I think thats also what made me lean towards them. More xmax and lower FS usually means better lows. Well, I'll try and talk my bro into waiting a bit and maybe saving up for the bl's.

Well, now you're just making assumptions ;P. I have two 15 inch dual 1 q's with bp already. One I'm selling, and the other is in a HT setup of mine. So, thats what I mean't by I'd get those if they were dual 1's, because then I could wire all four to 2 ohm load for strapped aq2200d's. Also, at some point in the beginning of my thread I believe I said something to the effect of to assume both subwoofers would be in their optimum spaces. I can most likely get 16 cubes. Won't be easy, but I think I can. Is that 16 cubes before or after displacements. The port for a box that large will take up a bit of volume, as well as the bracing, double baffles/walls, and the subs themselves. To me it seems that the BL's are what you want, as M5 stated. Also, what music do you listen to? There aren't many songs that I can think of that go much below 30hz, Bass I Love You and some slowed songs are what come to mind. Also you will need a bit beefier electrical to support 4k wrms. The two subs are designed to do two completely different things. The BL to get loud (though it doesn't sound bad by my standards) And the Q to sound good (gets decently loud, nothing crazy though). Most of is in the build though. Yeah I gotcha. Well, i may only be able to do 16 before displacement. So in the end I may be better off going with the Q's just so they can be in their optimum environment. It's more driver size that will dictate whether you can fit them in there. Perhaps either two 18"s or four 12"s would be a better route. Well, I can physically fit four 15 inch woofers in the box, but what I was referring to is, doesn't the Q's optim. ported enc. size a bit less than a bl's?

Hey I went a head and looked through your guidelines thing. Sorry I didn't mean to start this up if its all frowned upon and whatnot. I'm confused what you mean by misrepresenting the lows? Do you mean my definition of low is too low? lol Like that what I think is 25 hz is really 35hz? I think I need to get out some programs and figure out exactly how low some of my favorite songs are.

He used to have the same setup as me with (2) hdc3 15's off of aq2200d's. We both eventually decided it was good but wanted more sq/low end.

Thank you everyone. I discussed this all with my friend and he seems to be leaning towards the Q's, since it will also save some cash for sure. Will be sending more people in Fi's direction in the future!

Yeah I thought that the second post under the first one in the guidelines said if you had 10 plus other feedback it was cool. But I guess not lol

Hey everyone - I want to put some stuff up for sale here but I don't have a lot of started threads so, here is my current feedback areas on other places. silenkiller A++++ SELLER silenkiller = A+ seller Ebay Username is: CenterMachine (over 70 positive feedbacks)

See that's kinda how I have been thinking about this. The dude isn't going to be going to comps or anything. So four Q's off of 4000 watts should be loud enough lol while still getting that added low end that the Q line provides. Yeah I agree with that. Hm, a Q will take 1000 watts all day without any problems right? <-- Ninja edit: Yeah just read the post above, thats what I thought. That they take 1k fine. Blah this is hard. I should open a shop that has entire car audio product lines setup for comparison side by side to help people make decisions lol

Well, he listens to broad range of music - and there are plenty of rap songs out there that are in the low 30's high 20's anymore. Hm, has anyone ever put the bl in winisd? Shows a wild curve whereas the Q seems to be a lot more flat.

Eh couldn't hurt. But there is no drop as of now so meh.

So, really, unless your are trying to do SQ competitions, for the average person who likes their subs to sound good and get loud, the bl is the way to go. Now, I just wonder exactly what the low end difference is between the Q and BL. There is a lot of music out there that has 26-30hz parts that are wicked when your setup can push them out. If the Q hits the lows more (more xmax?) exactly how MUCH more, is the question.

Alright, so hows this for a comparison. Both setups would be on 4,000 watts rms. Both would be ported to optimal space. Aside from the Q's costing less, what would you expect the differences to be? Also, both applications would be tuned low to optimize the low end. Most likely 27-28 hz tuning. Q's louder around the 30hz and under, Bl's louder on the 30hz and higher notes? That's all I can think of. Honestly though would the differences at 30hz even be really that noticeable? I'm trying to advise a friend of mine who is interested in building with Fi products. These would be 15's, by the way. Maybe 12's if the space ends up not accommodating. This is going in a walled car, subs/ports into the cabin. H.O. Alt and a big batt in the trunk already. My buddy isn't an SQ competitor or anything, but he wants it to sound good because of his broad music. Rap/Rock/Techno/Metal

speakers dont require you to put full power on them. with a statement like that i suggest you follow the posting guildlines and give us more info so we can help you and your buddy out before a mistake is made. Ahem. Well then. He has 2000 rms right now, flirting with the idea of taken it to 4k. Can fit about 14 cuft of space in the car, maybe 16 but thats pushing it. (walled off) Likes to hit lows so will want to tune to 28ish hz. Has the electrical to backup 4k if need be. Likes the idea of having 4 subs because its different and has a lot of wow effect. Not a lot of setups like that around here. Hmm.. I think he ran some AQ HDC3's before and was impressed with how loud they got but wanted more on the low/sq end of things. Thats why he is thinking about the BL's. Four bl's is outside of his budget, so thats why SSD's would have to work, and theres no Q pricing right now. Q's may be an option for four but they are more of an SQ driver?

Buddy is torn between these setups. Obviously one requires 2k more power. Aside from that, everything else is pretty close. I think that the ssds wont be much louder for all the extra work - any other opinions?
