10's or 8's...worried about low end.

My 8's go into hyperdrive when hitting lower frequensies! I can hear them about to blow out of the box. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

The point is, you really have zero reason why a ten is superior to a pair of 8's, beyond cost. Many times its possible to fit 8's due to depth, while 10's will not fit. But if people listen to you, they think running a pair of 8's would be settling. In fact, when comparing apples to apples, a pair of 8's should outperform a single 10 in almost any application (besides cost).
Yes, sealed box systems are simpler, this does not equate to 10's are better than 8's, 12's are better than 10's, etc.

dude you are talking about 2 8's or 2 10's...

besides that even ported you are going to have a hard time matching 2 8's to 2 10's sealed i don't see what the huge discrepancy is... when comparing subs (of the same series) if cost not a factor, the bigger size is almost always more sensible...

bigger size subs in comparison just have more potential... PERIOD...

now with the option between 2 8's ported and 2 10's sealed, i think it would be simpler, easier to get right, and not a whole lot more expensive, if not less expensive to get the 10's

with the JL's you can upgrade from an 8 to a 10 for like 10 bucks... i'd say thats pretty worth it... if you think about it, (SEALED) it would take at least 3 8's if not 4 to match 2 10s...

3 8w1's are gunna run bout 300 bucks

2 10w1's are only gunna run about 220 and hit lower harder

so yeah porting minimizes the advantage but i still think 2 10's sealed would do better than 2 8's ported, not in ever application of course, but the chances are good

i would like someone to correct me if i'm wrong, but i don't believe there is a single series of subs where the smaller versions have more potential in low-end output than the larger versions

i wouldn't reccomend it, the crumbs might cause a short, and i don't think they are hungry anyway

**** it just get some 8" l7's

dude you are talking about 2 8's or 2 10's...

Are you having a hard time keeping up? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif The OP asked about four 8's or two 10's. Do the math.

besides that even ported you are going to have a hard time matching 2 8's to 2 10's sealed i don't see what the huge discrepancy is... when comparing subs (of the same series) if cost not a factor, the bigger size is almost always more sensible...

If you think I am, or will compare two 8's sealed to two 10's sealed, you're nuts. That's an idiotic comparison, and you even trying to bring it into the convo, yourself or by misinterpreting my comments as such, is equally idiotic.
If you are saying two 8's ported would have a hard time keeping up with two 10's sealed, well you're just plain dumb. A generalization that shows your true lack of experience, even though your mouth says otherwise all the time.

bigger size subs in comparison just have more potential... PERIOD...

I love it when you type in caps, it makes finding your stupidity highlights so much easier. Way to overgeneralize. So my 12" PPI Pro, with its 5.5mm xmax and tiny power handling, has more 'potential' than say... a 10" XXX? Hell an RLi8 would destroy one of my PPI Pro 12's in output, you moron. And again, even when dealing with same model subs, an 8 ported has similar output potential to a 10 sealed.

i would like someone to correct me if i'm wrong, but i don't believe there is a single series of subs where the smaller versions have more potential in low-end output than the larger versions

While the Fs lowers as you go up in sizes of subs within the same model, usually the difference between one size (8 to 10") is a hz or two. So even any freq response arguement you'd want to try and make at this point would fail. Just give up trying to look smart, start reading, and actually become smart. Jesus Christ how long is it gonna take to realize not only do you not know everything, you are way out classed by many people here. Learn to respect what some of us try to tell you, even if your feeble 19 year old mind finds it hard to grasp at first. In short, get a clue.

 

[cotjones 10+ year member]

the only one acting idiotic, and like you know everything, is you...

i said that if he went with 4 8's sealed he wasn't gunna get as low of a responce as with 2 10's

then you said he could do 2 8's ported, which still normally wouldn't do as good as the 10's of the same series...

seriously dude, i know it's cool to flame cotjones and all... but use your common sence, i know you have a little...

i was OBVIOUSLY talking about comparing 8's and 10's of the same series, if you couldn't understand that then you are dumber than you are trying to make me look...

the jl 8w7, the kicker 8" L7, and many other 8's could kill even some 15"s in output...

instead of nit-picking what i say with the aim of making people look like dumb-*****

why don't you just wake up and help this guy get the right thing....

so for the OP lets look at your options

3 er 4 8's sealed = really expensive, not very efficient

2 8''s ported = really in-expensive, hard to design, hard to build, not the best possible performance...

2 10's sealed = fairly in-expensive, easy to design, easy to build, great performance on both low and high end .... flexibility for future applications, better resale value... (who's gunna buy cheap second-hand 8"s?)

honeslty dude grow up

if you are looking to get maximum output then it's pretty much stupid to get 8's unless you have no other choice

also, something else to consider, not only is the fs lower, but the displacement at fs is higher, due to the increased surface area, and usually increased power handling and excursion

the Fs doesn't really even neccessarilly matter, what matters is that when the cone is moving 20 times a second, the more cone, the more air moved...

Your forgetting alot of factors here. First off let's think in terms of box requirements. For the same model subs, usually 2 8's will take up the space of 10 to achieve the same overall q. Two 8inch subs also have appox the same surface area. Assuming excursion values are the same, which they usually are, you end up with the same displacement potential. However, you've gained a few key advantages doing this.

First off, you'll suffer less power compression as each driver will run off of less power, meaning even if the theoretical spl's are the same, the pair of subs will probably get louder at full tilt. The second key advantage is your motor to cone area ratio, more control overall on each woofer.

If you port a single 8, you've gained similar output of 1 10 or 2 8's sealed depending at a given range of frequencies. This is important if you don't have a huge amplifier on a tap as your effeciency is MUCH higher than that of either sealed setup.

To say a larger sub is better in any scenario is ignorant. There are too many factors to make a general statement like that. If I wanted to run IB on my rear deck, I'd use 6 8's or so, it's the same surface area as 3'12's, but I'd suffer less power compression, have more control over the suspension (important in IB). Not to mention it'd actually fit...

It's stupid too even own 8's to start out with. You don't have many choices these days anyway. Most companys don't even make 8's anymore because there's no demand for them. People with good sense know you need at least a 10 inch woofer to get decent bass performance out of your car. The only times 8's come in good is if you have limited space like I do in my truck. But then you have to do a sealed enclosure and thats a waste of time for 8's. If a 8 ain't ported or in a bandpass box it ain't shit period.

again porting is different, i ment sub for sub, and enclosure for enclosure the biggerr sub is better...

so 1 10 of a series ported will do better than an 8 of the same series ported...

but keep in mind we aren't talking about 10's vs 12's

we are talking bout 8's vs 10's

picture porting 1000 tweeters for your bass... your still not gunna have any...

but while 8's ported can produce significant low bass,

8's sealed generally have a harder time... 8's are more suited to play loudly in the mid-bass range... because at a low frequency say 25 er 30 hz... displacement is what translated into output...

it's not hard for a 8 to get loud in the higher frequencies because the cone is moving air many more times per second...

on the contrary, its very hard for a 12 er 15 to play loudly in higher frequencies due to cone mass and many other factors...

in other words... if you have 8's struggling with the lows even if you have 50 of them... they are 50 struggling with the lows

I'm going with 8's... Am i stupid?
