Small Boxes tuned low vs Large boxes!

[tooloud4tv 10+ year member]

Well heres my opinion on the 2 baised on experience. heres my inaccurate review. ive noticed that with Small boxes even tuned low i get WAY more output vs using an larger box no matter what the tunning would be in the larger. example i had 2 15" American Bass DX woofers in about 2.2-5 cubes each sub powered by an Kicker KX 2500.1 and honestly on sheer loudness it wasnt far from myPrevious 4 15" Kicker L5's in an 16+ cube box tuned to 37hz. only difference i noticed is that the kicker had WAY MORE low end, but it seemed like the 2 15's tickled my ears a bit more. that small box was tuned to 30hz. so im wondering what make the smaller boxes soooooo much louder? i was also able to pull an hair trick wit the smaller box/port but the bigger box with more port wasnt able to move as much air? ive noticed alot of the louder guys perfect example STEVE who only has about 5 cubes per 18 and i think 120sqin of port wtf? is smaller the way to go now? another question is dealing with fs who else has noticed that its a bit more painful in the high 30's/37-9hz and 40's 40-49hz that it is in the LOWWW freqs like 30hz?

im asking these noob questions because i just got an PAIR of 07 RE SX 18's and im not sure WTF to do Box size wise. not sure if i just want it PAINFULLY loud or KILLER LOWS? what do u all think?

its all sub/box Dependant.

really depends on what you're running.

well with about 2000+ rms each SX i think smaller box would be better on the subs and louder u think?

Have you metered any of these to actually know what was louder?

that it is in the LOWWW freqs like 30hz?

30Hz really isn't all that "low".

every woofer has an optimum enclosure size...if they are

installed into a enclosure larger than the optimum volume

the sound becomes mushy with less impact....

if the recommended inner volume range is 1.5cf3 to 2.50cf3

building an enclosure at 2.0cf3 "right in the middle of the recommended range"

will usually give the best power handling ,impact and sound quality

although alot of people will build an enclosure at 3.0cf3 thinking the extra

cf3 will increase out put and deepen the bass

Less output, sure, but what's IB? In principle a really, really, really larger-than-recommended sealed box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I happen to like alignments lower than the typical Butterworth value of a 0.707 Qtc...but everyone's different.

[tooloud4tv 10+ year member]

In the SPL world it is, but you don't see it that way

Small boxes tend to work well for spl. The box is more likely to be peaky.

No, because a small box may be louder to the ear, but will without a doubt lack the low frequency extension of its larger enclosure (assuming you're running smaller than optimal).

so bigger box is more efficent but when u get tooo big of an box thats when subs fall on there face right?

Exactly.
