I have an '02 SCrew I wanna put some bump in. I'm going to have the box on top of the rear-passenger seat (laid down). I have two Pioneer 8" subs but am thinking about going to a single 12". My main question is what box design to go with. I'm leaning towards bandpass but what do you guys think? I mainly listen to hard rock.

 

You can't go wrong with 2 - 10's in a ported box. I listen to rock also. I put a 12 in my car and the bass just doesn't sound right. Don't know if the sub can't keep up with the music or what. A 12" sub is a lot of speaker to move for rock. It will hit some awesome lows though. Just my $.02.

 

Exactly.
12" is quite a bit to move. It's excellent for low, long lasting bass, such as synthesizers... but not for quick beats on bass drums, etc.

2 10's or 2 8's is best.

 

I agree with these two-if you only listen to rock go with 2 or 3 10's. They just sound a little better for rock than 12's.

Outta those 3 boxes if you want it loud and to hit hard the bandpass box will do that better than the other 2. Although you can still make a sealed box rock. Unless you have the other boxes tuned a sealed will almost always sound better than a ported of bandpass.

If i were you I would go with 3 10's. You can make em rock even in a sealed box.

 

Go with the sealed box, the subs will keep up just fine... don't go any bigger than 10's if your just listening to hard rock. Your pioneer 8's will rock, just make sure that you match the RMS watts from SUB's to AMP. But, 10's are a great all around sub for any type of music. you won't be sorry either way.

 

That's the info I was looking for. Sounds like I may not need to bother going up to 10s. I'll be looking for a bandpass box. Now I guess I need a bigger amp. I have a 50w Pioneer currently.

 

Yeah, you might want to go to a 100 watt or 150 watt amp for your subs. Also as far as boxes ar concerned, read this:

Sealed - is the most common subwoofer box and easiest to build. These boxes will give the flattest frequency response, and best overall sound quality (especially at lower frequencies). The subwoofer enclosure internal volume should be as close as possible to the recommended by the manufacturer. If a subwoofer box is smaller than what it is supposed to be, the sound will be tighter, but more amplifier power will be required. If the subwoofer box is too big, then the sound will be muddy.

Band Pass - enclosures consist of a woofer between a sealed and ported box. Bandpass subwoofer boxes will yield more bass than sealed and ported subwoofer boxes (especially at lower frequencies), but over a narrower frequency range. Since the subwoofer enclosure acts as a filter, mechanically blocking lower and upper frequencies, a crossover is not needed in most cases. These subwoofer enclosures are usually big, and very unforgiving when precise volumes and port sizes are not followed. Bandpass subwoofer boxes also tend to mask distortion. If you can't hear distortion and turn your stereo down in time, you could damage your subs.

I got 2 15" subs in a bandpass box in my truck, i did a cut through as i needed about 7 cubit feet. i must say though my truck pounds. i am adding a 3rd set of speakers just so i can keep up with all that bass. I say go with the bandpass box it gives out some nice responsive bass. btw i listen to a lot of punk and my bass is able to keep up with music just fine, as i have the power to push my subs.

 

just do what i am and have the best of both worlds!

8"s in the front doors, and a 10" behind the seat. pictures are in my gallery of the sub. i haven't put the 8"s in yet.

 

How are you putting 8s in the doors?

I think I'm going to keep my Pioneer 8s and get a bandpass box. I did some research on that amp and it's 50w, but supposed to be 150w bridged/300w max. Think that's enough to power both speakers?

 

If your kinda new DO NOT build a bandpass unless you get a really good print/design from someone who knows what they are doing..Generally they suck unles they are perfectly tuned...Size depends on your taste and budget ..you will be great with 2-10's sealed or ported..Or a 12 sealed ...If your not looking for a big boom...


I did a cut through also this winter,with a ported box with 2 -12'scheck in my gallery too...Probably better pics here...

enlarging the current hole, and making a plate for the 8 to mount to. it should not be too hard. i just need to finish my kick panels first.

 

So you use freeair speakers for that? Won't that take away all your midrange?

 

i will also have a 5.25" component set in some custom kick panels. i am using kicker rmb8 for the doors. they are dedicated 8" midbass drivers, but they are designed to be thin, and only need 2.25" of depth.

heh, in all honesty, i think bandpass sucks ***.....hella distortion. no offense to those of you who like it or have em tuned up nice, but i have gone through two bandpass boxes and they sounded like crap. i love my sealed box but it takes up to much room.....i am currently building a custom slot port box that will sit in the 40 part of the rear bench (imma take that section out and just have the box there) so that i have the 60 part of the bench for two people to sit. i got two 12's and they are bada$$ for all music, rock, crap, country, etc.

my friend has one JL w6 with 500 watts to it (they can take up to 1000 watts) and when it was in his sealed box it was moderatly loud, then he put it in a sealed box built to the subs specs and holy cow.........you cant here yourself think....then he went and added two sets of JL components.........you can sing along with his beats from seriously 8 blocks away.


i would steer clear of bandpass..........get sealed or slot port. whatever you do make sure the box is the specific dimensions that is required for the subs, then they will hit better.

peace,
