shogen Posted May 30, 2013 Report Share Posted May 30, 2013 again ... we're just trying to give proper info .... you're asking and we're providing.... bigger box adds efficiency to a degree... obviously too big will cause over excursion as will not setting SSF properly ... tune lower if you want to play lower.... 32-35hz should allow you decent output on mid 20's ... obviously you should model this in WinISD to get a better idea of the response it would put out at certain tuning .... but it's just a reflection of possible output.... your install will yield many differences due to air space in the vehicle and shape of vehicle as well... just food for thought You guys is bosses!

Mikhail Felton Posted May 30, 2013 Report Share Posted May 30, 2013 the obvious thing to do would be to TUNE lower not use a larger box.... he should have the ability to due it that way which is the RIGHT/BEST way to do so Obviously I wasn't on top of the right thread.... but I'd honestly not recommend all this for OP .... inexperience can cause a lot of mayhem in itself.... I'd say go for mid - lower side to be on the side of safety with all that equipment.... That's just my opinion those specs are not posted anywhere edit:on sundown website or SSA where they sell them. http://www.stevemeadedesigns.com/board/topic/164370-sundown-x-series-10121518-pre-order-eta-june-2013/ Scroll down a little bit and there ya - post #16 by sundownz.... Right here on the SMD forum... he wants more lows so a larger box would be better.. Im sorry but im learning alot from you right now.. a larger box will give him more xmax for better lows and plus tuning a 4 cuft is easier than a 2cuft box.. how so? the Fi Q has the xmax of 28mm and have no problem getting low it has to do with the tuning. bigger box is more efficient which will get you louder with less power not hit lower notes it easier to tune a bigger box lower than a smaller box and to hit lower notes 25hz> you need xmax and air. a bigger box is going to allow for more xmax to produce the lows needed to be louder.. to do it with a small box you will need more power..

Im sorry but im learning alot from you right now.. a larger box will give him more xmax for better lows and plus tuning a 4 cuft is easier than a 2cuft box.. All having a larger box does is relieve the driver of some of the back pressure pushing back at it causing less control over the linear motion. You lose control over the sub also by playing below tuning which is why it is recommended to set your subsonic filter as close to tuning as possible. When you lose control you run the risk of damage: such as the coil rubbing and bottoming out. I would suggest you to sit back, don't touch any equipment, read much more of the forums, and ask educated questions related to box design and a system's electrical. Hell two subs on 3.5k will hit lows! Be smart and build a box when the specs are released and you have the sub in your possession. It's not a smart thing to build before you order/own the sub(s) you are building for. while im building my box off these specs and im going to be happy with it.. 10 cuft box total 8 cuft =subs 2 cuft =port If your using 10's or 12's send me your motors after you blow them.

Krakin I've tried reading up and posting threads, asking questions and I always get different answers. Always. I asked what size alternator I should get, some people said 250 with 3 batteries, some said 270 with a couple batteries, a lot said a 370 with 4 batteries cause they like overkill. What's your OPINION on what I need? I know that there are always debates, thats why i want an opinion.

Right here on the SMD forum... he wants more lows so a larger box would be better.. Larger box = higher peak in response curve Smaller = has a flatter curve. Shit changes depending on every vehicle. Just because its big doesn't mean it hits the lows or small hits the highs, thats with port tuning. Unles you get excessively small or large. For daily I would bet the OP would be happy with something on the smaller side because it would be more musical. The subs will do fine in a big enclosure on over rated power, look at the mechanical travel they have when he tests them free air on over rated. If the OP wants the Lows, he clearly shoudl do a 18th order reflex bandpass with quatrro ports and double coupling loading walls. In all seriousness I would lov eto see one of those new sundowns in a 1/4 wave/Tline build with all that excursion and the fact that they can take almost rated free air without bottoming. I was seriously contemplating it before I decided to give away my Tline, tuned to high 20's it was surprising with 1 vvx10, one of the z4 10's on around 2k would get down.

What's your OPINION on what I need? I know that there are always debates, thats why i want an opinion. You know what I'll be running. I currently haven't gotten into changing the alternator in my truck yet so I'm not going to give a direct answer on what you should get. I have not heard anything bad about Mike and his products. As for battieries those are nice as a "safety net" to try and keep from damaging some equipment. But too many batteries for an alternator becomes a strain. Because just like the amp a battery is another component of the circuit. If I am wrong on any of that and anyone has anything that they would like to add/critique please do so, just please have a way of explaining it well of some sort of proof just for all viewers to get a better understanding of this topic. I would study up on Ohm's and Kirchhoff 's laws for circuits, mainly Ohm's I'm a little weak on Kirchoff since my electrical course focused on Ohm's. Some starting points. I know that Wikipedia can be somewhat overwhelming on some topics, but anything you don't fully understand, google doesn't have closing hours or breaks.
