Built a sub box to sit right up the front of my boot for more boot space. Now I think the box is a tad big for my old pioneer sub. Just measured it up at roughly 37litres.

Is that way to big for a single 12 or has anyone got an idea of a sub that will suit that size enclosure?

Thanks in advance
Kyle .

Actually. I measured wrong. More like 30liters. I forgot that the box had think walls.

So, thats about 1.35 cubic feet.
But, which amp will drive it?
Is it ported, or will you port it?
Or do you want to keep it sealed?
Whats a good price?
What music do you listen to?
What other speakers do you have?

Seeing as its a pioneer mono, and in my previous experience, I've found them to a little lacking.
There is a Rockford Fosqate P1 4 Ohm 150 rms 12" woofer that needs a 1.4 cf box with a 3" x 8" port.
Its under 200.00.
But there is plenty out there, depending on power.
I can do a vid of one if you like.
If you run your mono at 2 Ohms, you vould get bigger, lots bigger, but the woofer needs to be 2 Ohms bro.

Its n old pioneer sub. Had it for years. Its a sealed box and I think the mono is 600watt. I'm not after comp winning lol. The sub just sounds a bit funny now. It used to go hard in the tiny prefab box I had.

I've got vibe splits up front and mtx 6x9s at the back run off a Sony 4 Chan. Gonna put splits in the back soon.

don't wanna spend a huge amount. Just seeing what would suit that size box better.

If thats 600 watt printed on the top, its 600 peak, with about 300@2 Ohm, which gives you a large choice of 300 watt dual voice coil four Ohm subs or 300 watt 2 Ohms.
Kicker, alpine, jl W0, man there is heaps, that may lead you back to a sealed box tho.

That's cool I built my box to suit the boot space. Don't wanna go to auto barn ot supercrap but that's all that's round here. What bout option audio.

So do you want the biggest kick, the best Sound quality, or a mix say 40% SQ and 60 SPL......



What bout option audio.

I would rather recommend a hooker with herpes than OA, lets keep it a last resort.... There is plenty of places that will post, or members to help out.

Next Question $$$$$$$$$?

I'm not a huge Alpine Speaker fan, but this would do Fine (http://www.crutchfield.com/p_500SWS1243/Alpine-SWS-1243D.html?tp=111&tab=detailed_info), If you amp is in fact 300 WRMS at 2 Ohm..... (I 'd really like to confirm this before you move on, or even seriously consider a new Sub).

They are 219 RRP Australian.

Oh, and if the ideal box size is a bit off for the Sub of your choice, you can all add a solid fill to reduce the volume......

But all of this mere speculation, until the amps real outout is known, the model number will do fine.
Then we can get serious with suggestions and you can see what other people think.

if the box is only 30 litres, its far too small for any ported 12inch sub.

yes, really?

It actually lists the 1 Cubic Foot as the minimum size on their Website FFS!
It also says it may be impeded by this size box.
But that may would be taken into account when pushing that sub to the limit.
I have run and heard this sub, in my car, with my monobloc, with that sized box, ported and it sounded great.

And that was just one I knew about off the top of my head.

Here's another, But this is .8 of CF ported or sealed. Minimum size.

But as I have said in the thread earlier,

man there is heaps, that may lead you back to a sealed box tho.
So, instead of saying what can't be done, how about adding something that can be done......

Peace Out......

so?

the "recommended" 1cuft box is tuned to 48Hz, kinda pointless having a sub if it doesn't do sub bass.

also, the OP has a 30 litre box, the woofer displaces 2 litres, leaving him with 28 litres, but then the proposed port displaces another 2.5litres, so he'll end up with 25.5 litres tuned to 50Hz.

don't try and find a 12inch woofer to suit your tiny box, either run it sealed, or possibly go with a 10inch sub.

Ok I've had the pioneer sub that's in there for a while now. It was in one of those tiny prefab angled boxes (sub n box came in an old car of mine) I built a box to suit the shape of the boot in my vrx. Can post pic if needed.... Put said pioneer sub in it and it just doesnt sound the same as b4.... So I've assumed that either the box I've built is too big or the sub is getting a bit tired ...

The model number for my mono is GM-D7400M.

Maybe invert the sub? Can the distance between the back of the sub and the side of the enclosure be a problem.

Ammo, never once did I suggest a sub for that box and put a port in it, once I linked to a woofer on a site that states the sizes for ported and sealed, and the other I stated it needs a 1.4 cf for a port.

However, I did ask him if he would/wanted to port it. Early in the thread.

I only posted that info about that woofer, and the Kenwood, in reply to you, just to show you that you were wrong in the statement you made.


if the box is only 30 litres, its far too small for any ported 12inch sub.

Then, I don't know why, you come up with the strange idea that 50hz is not Sub Bass. Sub bass is widely considered to be anything below 100 Hz, but Wiki has it at 90.



Get with the program. Sheesh......

Now That Amp Specs.

CEA 2006 Power (THD + N = 1%) 1 x 200W (20Hz - 240Hz/4Ω)
1 x 400W (50Hz / 2Ω)
54 dBA (ref: 1W into 4Ω)

Looks Good
so 2 Ohms will get you bigger bang for your buck. And I'd be happy, if it was mine, to run 3-400 watt Sub, 2 Ohm Rated or a 4 Ohm Dual Voice coil. I wouldnt Press for a 500 Watt Sub, they get a lot harder to run/push in a sealed box. So I'd opt for a 300.
Have you got any in mind to suit your budget? That Alpine looks to be OK, it wont get as low as it can, but probably lower than the Original Pioneer in the small box and the one you have now.

How will the Alpine go in the 30 litre Box (sealed) Ammo Jammo? You any good with those Simulator thingys?

Did you line the inside of the enclosure with anything ?
Dacron sheets used to be used inside sealed subwoofer enclosures to stop them from sounding Hollow and Boomy.
I wouldn't be too fussed on going an enclosure that is too large, only an enclosure that is too small..

what pioneer sub is it?

Could port just about any 12" in that box if you went isobaric but that's just unnecessary expense. Bonus to staying sealed is you can choose from crud loads of subs and just plug unneeded volume :) personally I would probably chase a ported box with an external flared round port and play with port tuning. If it doesn't work out, plug it and go sealed.

If your pioneer is a 30x series later than 304, I really doubt it'll be getting tired.

na havent out anything inside the box....

Might reverse it today and see how it goes, sounded awesome in the little prefab box when it was reversed.

dont know what the model of the sub is until i flip it but it looks like this one and it looks oooolllllldddddd.

as for other subs, i dont wanna spend huge money but i just want something that my amp will run really well is the enclosure thats been built.
Dont really wanna port it either as ive had ported b4 and much prefer a punchy sealed sub.

Thanks everyone for ur help so far :)

Actually just reading the specs it does sound like the sub i have and the Recommended Enclosure Use is - 0.85 ~ 1.75 Cubic Feet...... maybe the box is too small and i need to invert it.

If you can try out the inverted mount without damaging anything, you be mad not to at least try.

I can understand that you want to make improvement in your bass system/sound.
But want I don't understand, is why you want to keep the cheapest part of your system, the box, and look at replacing the speaker, which might land back in the same predicament.
And just about any shallow mount sub could work in that box, but with a new sub being 2.5x the price of a new box/made box. It might even sound the same or just marginally better.

Its widely known that a cheap sub in great box, can easily sound 3 x better than a dearer sub in an unsuitable box.

I know its against the original idea that created this thread in the first place, but a new box designed with your woofer in mind, would get you the best results, for the least outlay.
Also, I googled sub box design in you tube and there is walkthroughs on entering the specs of the Sub into 'box design' programs. To what results (Db @ Frequencies) you can acheive.
But the bottom line is you want great Bass, you are going to have to compromise somewhere.
This I know, I had a 2.5 cf slot ported box with a gas tank. The bass was MAD:facejump::woot::facejump:
Now I am back to a 1.5 cf.:nuts:
