i'm pretty much a SQ guy. i like accurate/tight bass that gets loud when you want it to. in the last 8 years i've owned alot of 10's and one set of 12's but i decided to give loud and a 15" a try.

so i am planning on building a vented box for this, keeping it at the recommended specs of 3 cu/ft tuned to 30hz. i modeled it in winisd and looks like it plays very smooth down to about 40hz before it starts to roll off.
that would be a nice tune, but if i move up to 33-34hz tune, i get a nice 1.5db increase at 45hz (somewhere around there) but less output at lower frequencies.

being that this will be a daily driver and i listen to alot of different types of music (mostly rap and metal) will i notice that difference between the two frequencies considering i've never owned a 15" sub before?

 

Err... just out of curiosity, is there a reason why you posted this in the SPL section?

Don't want to move it if there is a specific reason why you wanted it here...

 

do alot of people run sq with a 15?

 

yes, 15 are used in many SQ cars.

 

oops, sorry.
yeah it was intended for the enclosure design section. i was reading threads in both sections, didnt realize i posted it in here. feel free to move it.

but to explain, a 15 in my case, has nothing to do with SQ. i'm trying my hand at spl for a change of pace. hence the questions about box tuning and whatnot

 

I don't think you'd hear much difference. However, I'd suggest you stick with 30Hz.

Although if you want loud, I'm not sure this sub was the right choice. Mine in a 2.5cf, 25Hz tuning gets pretty loud...but not extremely so. My sealed IDMAX easily has more output.

Anyhow, it's a nice sub...and IMO unbeatable for value. Let us know how it works out.


Agreed.

 

well, i'm not looking to tear heads off just yet. still, i'm trying to do this with a budget state of mind, and for $75, if it doesnt get as loud at least as my current 10's then i will sell and move to somehting else.

i would love an idmax, too bad i cant afford one right now (house hunting)

 

I had one in a 2.4cf sealed box and it did good. Nice mix of low end bass and punchy midbass, sounded very nice in my friends 92 celica coupe off of 750+ watts RMS.

If you're an SQ guy, I'd stick to the lower tuning so you get a little bit less group delay in the midbass area, should keep things sounding cleaner.

 

I think you're going to be pleasantly surprised with the sub.

BTW, good luck with the house hunting.
