Subwoofer And Space

[Caaine]

Hi,

Been discussing this before, where to put a subwoofer. What space to sacrifice etc. Then it struck me, a silly simple solution which at least works for me and probably a lot of you.

Get a box with a sub, place it in the middle of the trunk. Make it hold in place using french zipper (zinch) or whatever it´s called. It´s stuck in place, you can have the Wagon cover over it so the subwoofer doesn´t show and you can just remove it when you need the space.

I had been brainstorming about this till I figured that 85% of the time, I don´t use the storage space and when I do need it I could just remove the subwoofer, leave it at home and use the storage space.

A perfect subwoofer for this is one with a built-in amplifier, just need a couple of cables running to it and Voila!

If anyone is having the same issues I had, I hope this helps.

yeah, i didn't fully secure the sub box in place...the 10" sub and the box i got fits just perfectly under the cargo cover, and doesn't slide around too much. i also got some of these that allow u to quickly and easily remove the speaker wires, which i put some flexible speaker connectors at the end...

Yeah I did pretty much the same thing, I would stay away from the built in amp though... personally I mounted my amp under the floor, and just have speaker cable running up through it. This way I just have to disconnect the speaker cable and most of the time things will get thrown on top of it without any problems.

You can get subwoofers that do not require the "usual" 1.5 cubic feet of airspace. Some only need .75 cu ft. Depending on what kind of music you listen t,. Generally the smaller 8 or 10" woofers are more suited to rock and other non-bassy music. They throw quicker and have quicker response, whereas 12, 15, and 18's are for rap, electronic, and other uber bass types of music. I have a JL 12" in my spare tire space in the trunk and its so darn loud, and I listen to mostly hard rock and metal, I'm thinking of going smaller. Hope this helps.

build a dual 10 isobaric box, and you can stuff it anywhere haha ;)

isobaric?

[maiku]

if i remember from physics, isobaric means a state of constant pressure..

what he's trying to say, i'm not quite sure...

[Bing_0]

an isobaric enclosure is where one sub is mounted normally facing cone up, and another sub is mounted upside down on the first sub, basically cone to cone, usually separated by a baffle. you wire the two subs out of phase with each other so as one cone pulls, the other one pulls. with this format, you can mount two subs in the enclosure space thats required of only one sub, and double the power handling and your bass will be very controlled...

but I really just threw that out as a joke i wasnt too sure about waht this whole post was about... seems like a lot of common sense to me

Actually you mount 2 subs in a box that requires only half the noraml airspace of one sub (i.e. your normal sub requires a 2 cubic foot box, mounted isobarically the 2 subs now only need a 1 cubic foot box).

I used isobaric designs exclusively for a while. They are said to balance out cone imbalances and allow your subs to play much deeper. Unfortunately they are not as efficient as even a single sub in a sealed box.

Here's an official description:

A type of speaker enclosure used for subwoofers and bass drivers which uses a small, sealed enclosure with two bass drivers facing each other (one inside the box facing out and the other outside the box facing in at its counterpart) and wired out of phase. The primary advantage of this type of configuration is that the enclosure is small – about half the size of a sealed enclosure for the same output. The enclosure must be sealed and the two drivers must be sealed together. Isobaric enclosures leave one driver essentially hanging out in the open air making it a somewhat challenging configuration to achieve due to aesthetics and the need to protect the driver outside the box. This type of configuration is sometimes found in car audio but is rare in home theater and other home audio systems.

That sounds pretty pimp looking B)

[Chris_R]

It is if your sub has a good looking basket.

yeah, i guess i was confused about what the "half enclosure size meant" i personally never built one, mainly becuase i was always told that today's subs dont quire isobaric loading to sound good

You're right, they don't. But I've had small import cars and BIG bass wants. Not so much 'loud' as 'deep'. These days they are mass-loading the cones to produce a similar effect with only one sub... For example the Kicker SoloBaric. Cadence's SoloBass line is/was another.

The science of subwoofers has advance a LOT since I started into car audio back when I was 15 (I'm turning 35 next month, do the math! ).

yeah, i would say, if you want really small enclosures, go wtih aperiodic enclosures, smallest you can possibly, get, but hard to tune and hard to build...but proerply built once can sound amazing and take up almost no room at all...
