Sealed box = loud?

[tacomabanga1986]

my truck hits lows really good, but mine is a sealed downfire, downfires work kinda off the bandpass principle, forces air down n out threw a lil vent hole at bottom of box but still wangs on everything, i think my box is 4cf or so plus the lil end chambers i made for my midbass n run wires to subs n 6&1/2's

an upfireing sealed box aint as loud as a downfire is, or from my personal experence its not, ive got louder in an extened cab with a downfire sealed than one that fires up, and u have less motor noise too, plus it has less area to compress so it flows longer, but my truck hits lows real nice, but nothin down in the 20htz range, but 30's n so it wangs,

haha my sealed box hits lows better than it does highs

but the bigger the sealed box the better it is to hit lower, i unno why but it does work, but build u a downfire for those 2 15's n see what u get out of it, just make sure its atleast 3'' off ground for good air flow n so the subs dont hit and see what happins

once i built my downfire i love it, but i wanna do more of a show setup n make it alot cleaner, i wanna do an upfireing ported box or maby an upfireing sealed box but downfire sounds better

man i spent like 12hrs one day moveing boxs around n in n out of my truck to see what was louder n the downfire i built topped it all off

my system is in my sig, but i dont have any new vids yet, i aint got to tuneing it all back right yet so its still in the works, plus im goin active in a few for a more sq type setup so my mids n highs will be louder, my comps xover wont let it take as much power as i wanna feed em

anyways, all ive ran ecept for a few ported boxs, sealed have been louder, but it all depends on the subs too, my old rockford punch hx2's hated sealed boxs, so it depends on subs and amps too, but sealed tend to take more power than ported, but then again it depends on the sub too so its a hard question to ask

ported is more for gettin loud, but will not play all the freq's most sealed boxs can, but sealed boxs cant play what most ported boxs can, its all on what u want, if u want sql u can do sealed downfire is the loudest ive been in my truck, or ported i unno

awsome, thanks for the info guys, but i cant seal these subs up, only for ported box's. but i think 3500watts with 4 10's sealed up might sound pretty damn good, and the way im going to do it is a long rectangle box, subs firing forward.

u can get a bigger box if its downfire, unless u got a blowthrew already, ive tryed a long sealed box n didn't hit lows good at all, so i unno, anyways what kinda 10's u lookin to get?

no its not a blow through right now. and i was going to do the 4 10's in a row beside each other. 2.8 cube box, and dc audio level 3's

[tacomabanga1986]

oh, coo i was gunna run 4 cheap 12's but i guess i need to get more beafy subs n step up to 2000 or w/e

[Stallion Marauder]

sealed holds alot more power!!

[splzx3]

yea i kinda remember last year my 2 10" re, re series, they sounded pretty good, and seemed to hit low, but only with the windows down, but again that was only like 300-400 watts. so how low does the sealed hit, does it play jeezy and gorilla zoe stuff?

also, anyone have pics or videos of loud sealed set ups?

it dose jeezy and zoe super well

i will get some videos 2mor

A properly build and tuned ported/bandpass enclosure can do everything a sealed can but with more authority. 99.99% of woofers will be louder in ported in the exact same setup as they would be in sealed, also they can have the same or better sound quality as sealed.

My last sealed daily enclosure i build was a hexagon wall w/ 6 15s in it(tunnel setup) and my next will prolli be my upcoming 24 12s setups in a sealed diamond. In a more "normal" setup with say 2 12s/15s and a couple thousand watts or less I will never run sealed over ported/bandpass. Even if I was in a major space crunch I'd drop down a woofer size to build a ported enclosure w/ proper airspace, just never been a fan of sealed unless it's a huge cone area/power setup.

well i slightly remeber last year my 2 10's with 300 watts sound ok.. wasn't loud, but it sounded pretty clean. so im sure with a ton more power it would have been loud. i just havent built a ported box ever that really played everything and really satisfied me, they worked alright on some music, but wasn't good enough for me.

What exactly do you want your woofers to do? Have you never heard a vented box that you liked the sound of.

I used to build a lot of sealed enclosures because it was what certain manufacterers recommended for their subs with mostly pretty good results in most cases. Sealed i.e. "acoustic suspension" enclosures, as the name implies, use the air trapped inside the enclosure to help control the motion of the woofer cone. This air compression is primarily a linear mechanical factor. Optimized sealed enclosures are thus able to offer a smooth linear response curve.

Below their tuning frequencies, all enclosures start to fall off in terms of volume. Sealed enclosures do this relatively slower than either vented or bandpass boxes; so, in many cases, a sealed box will have better very low bass than the other enclosures. However, all this control and extension has a steep price: EFFICIENCY. Sealed boxes take more power to acheive the same SPL than vented or bandpass boxes. In fact, you can often get one sub in a proper vented box to sound as loud as TWO of the same sub in a sealed enclosure.

That is because vented boxes use the air in the port to augment the primary output of the woofer cone at certain frequencies. Assuming we have a sub that works equally well inside a sealed or ported enclosure (unlikely, but just assume); the sealed box will not come close to a ported box in terms of output or mechanical power handling above tuning frequency. Also, depending on tuning and other factors, it is often possible to get more low bass output from the vented box despite its steep roll-off because it starts off much louder in the first place.

Are you sure you won't give a PROPERLY DESIGNED ported box a chance? You could be missing out. On the other hand, you have plenty of power so output is not your big problem, so maybe you just need to ride with a sealed box for a while before you come back over.
