Ahhh yes, old school RE XXX or SX, and Teampsi can build a nice sub for you too if you just let him know what your looking for...

and honestly, the same motor is used on the 12" lvl 5 as the 18" lvl 5...the difference being a bigger cone (among other larger components). So your telling me a few grams or so in weight will make that much difference that you can hear it by ear when your sending over 3k watts to it?
I'm not around the competition circuits at all, but I'd like to know.. how many SQ installs utilize 18 and 21 inch subs? as compared to 10 inch subs? Why then.. or why not if there is no advantage or disadvantage?
Back to the root of the question.. Generally speaking to the average Joe.... do quality 10 inch subs sound tighter or cleaner than the same quality 18 to 21 inch sub? Why?

do you understand that when you use a 18 inch sub, you need a fvckin huge box? let alone a 21" sub. Guy here with a 08 civic has 3 15" subs for his sq setup and it sounds amazing. Cost is another reason. SQ guys dont need to move as much air as us SPL guys either...

I used a 18 inch LMS Ultra in an SQ install due to low inductance, high BL, the ability to use such a small box and at the same time it has amazing output, long throw, and sounds great.
And many people that compete SQ use 10's I think because they are not looking for the output of an 18.
But in the end its all about personal pref. because its your car, your ears, but the fact still stands that 18 inch drivers can sound just as good at 10's in the same model of sub.
Your responses are showing you know less and less. Inductance has NOTHING to do with the size of the cone, it's a electrical parameter, again overall design is important, not the cone size when determining upper end frequency response.
Also go check you local SQ lanes again. Every big name car uses big subs or multiple smaller ones. Look at Hebrew Hammer, he used a single 18" sub IB a
Aura NS18. It's inductance is also very low, they play flat to over 1000hz. Why do they use either big subs or a couple smaller ones, because more cone area leads to less stress on the driver for a given amount of output, ie less distortion. To the average joe a 10 sounds tigher and cleaner because it's not playing the lower notes as loud, I already answered your question.

Your question has been proven wrong be me about 3 times now so please stop trying... thanks...

why use three 15 inch woofers? if you're saying a 18 or 21 inch woofer will give you the same? Box size would be comparable, both options would require huge amounts of space.
Why are there set-ups with 16 to 24 Eight inch drivers when the same could be done with less numbers of larger woofers? People just don't pull this crap out of the air do they.. or are they hearing something different?

personal preference...and yes, they pull it out of thin air. People want to be different. I have seen vans with 4 15's that are way louder then a van with 24 12's in it, but everyone loved that van with 24 12's because it was so much different and moved a shit load of air...

My 18 used 4 cubes sealed //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
that many drivers has nothing to do with SQ. Now your talking about upper level bass race cars lol. Most people that do setups like that do it for a few reasons. The biggest being that if a driver fails midrun you lose alot less SPL as each driver wasn't contributing as much. If all your running is 4 18's and one breaks, you just lost 1/4 your output. Several drivers have to fail before scores change too much if your running 20 drivers. The second reason is the sheer amount of power alot of these guys have on tap. After you put so much power to a driver you hit a point where you really dont' get alot of gain by adding more. Using lots of drivers spreads the power out so you get more effeciency per watt of power. Less compression is a good thing. Lastly, they do it to look cool.

haha guys your knowledge is great and all, but in all seriousness...my questions =]
I'm looking for some sound quality suggestions as far as woofer's are concerned. What is the price of a DD 1508? I'm possibly looking into doing two of them...but how can I get them? There are no dealers close to my location

I know you said you wanted to go smaller but I would probably go with one 12 over 2 8's. Generally the size doesn't change the pricing enough to allow you to get two for the price of one. In short, you can probably get a nicer single twelve for cheaper than gettign two eights that are just as nice. Plus a single 12 has as much cone area as the two eights, takes up similar space and should meet your output requirments. I'd order a AV12x if I were you. http://www.aespeakers.com. I'd link you directly but my internet is being gay and won't load it for me. The inductance on these woofers is very low, lower than most midranges. They will play as high as 2000hz before they run into cone breakup. Realistically they can be run up to 500hz if you put them in a home stereo system if you wanted to though. They listed RMS is 1000 but you can probably put more on them if you are careful. A box anywhere between .5 and 1 cubic foot net will be fine.
If you need stuff faster and dont' mind buying used

He has alot of nice choices. I'd look at the si mag v4 or one of the 10" revo's. For my money the mag is the better speaker for you application though. He does have some 1508's if you want to go that route though.

he's having a sale on these to get rid of his old stock as he has retooled this model. The differences aren't big though so really now is a great time to buy. This sub uses xbl^2 tech and fairly low inductance. It'll play upper bass well and should sound super clean.
