Fi q 12in ported or 15in sealed

[Cruzer 10+ year member]

louder where? the higher frequencies? cause sealed boxes play lower. I run two 15 si mags in a ported box tuned to 30hz and i used to have the same 15's sealed and the sealed box played lower than my ported box. So i really doubt the 12 ported can talk to the 15 sealed in lower frequencies

music doesnt really go below 30hz very much. yes some do but most dont.

if u tune a ported box to 30-32hz it will play those notes louder than a sealed box.

yes sealed can technically play lower as it is more controlled and will not bottom out as fast as a ported box but like i said, u dont have 15hz in music. songs created do, like bass i love you, but turn on your favorite music, its never gonna go that low.

i have had two different 15" subs, sealed first, then ported directly after, and the ported was much much louder on lower frequencies.

you can also look at it with winisd, it shows exactly what i experienced with both the subs.

i have two polk audio 10s sealed, building a ported box tomorrow. ill bet money it will be louder on the lower frequencies.

as it stands, the 10s sealed dont really dig that low which is the whole reasoning for going ported. and they are overpowered and everything and cant play lows loud enough.

you can tell me im wrong all day long, but ive experienced it and i know which plays lower, at least for my setups

i used to be all about sealed boxes.....until I heard a properly built ported box. I am now a ported box guy unless space dictates sealed...my treo 15 ported at 30hz was some of the best sounding low end I have ever heard

**** there's a lot of tards. OP, ported and make sure whoever builds your box knows about the audio part and not just the building part.

What was the specs of your ported setup and what are the specs of the sealed setup? are you using the same amp, same car? just a n enclosure differance? what exactly do you miss from your ported setup? pro's and Con's of each enclosure would be gereat =) thanks!

Just to throw this in here, My 18" Q was ported in my suv, now sealed in my truck, and I miss the the old ported box //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Ported FTW

I've been doing a bit of research regarding the 12in fi q ported with a 2.5 cft and some seem to say that going with 2.2cft is a bit better sq, is this true or what's the deal about this regarding drawbacks using a 2.5cft oppose to 2.0cft thanks

Ported box tuned low FTW.

I had 32hz in mind so i can get somenice sound, is that low enough...

thats fine

I was having some second thoughts... i was thinking of going with the 12in fi bl and throw it in a 2.5cft @ 32hz that sub seems to be musical and loud....my only y concern is how would it do on the 2.5cft enclosure and does a square enclosure make a differance oppose to a rectangular enclosure? i don't think it does but i'm not an exp. car audio gurro

the BL will get louder but the Q will sound nicer and play lower

 

[ExplicitUrSelf 10+ year member]

Really the fi q can get lower? i was thinking that the bl can get lower since it's more beasty...

The "beasty" nature of the sub has nothing to do with how low it will play. Its Fs, Vas and Q combined with the volume and tuning of the box determine that.

not worth the BL unless you competing

Q kills the lows, bl's not so much

The BL is not a competition sub. It is meant to be a tough daily driver that can take a beating. The Q is meant to sound good and can get semi-loud but it cannot take the power or the abuse of the BL.

Stick with the Q if you're going for daily. 2.25ft^3 at 30hz will be nice.

ok, cool! this help is very informative thanks alot guys... so 2.2^3.0 @ 30hz is the way to go? i heard that 32hz was a good port tune... i was planning to get the sub fully loaded, what optiones should i go for? thanks!!!!
