Am I the only one?

The only advantage of tuning lower is going to be not burning up your equipment. Or like I said just play music with higher frequencies... (Thug motivation is 41-43 hz) it would be a perfect song for your box...however that doesn't mean that your resonant frequency is that tuning. You will do the highest numbers at your resonant frequency. You have to make some kind of sacrifices...
Ether you put up good numbers and are limited to the music tracks you can play

OR

You tune a box lower and you can play all the music you want, but it will most likely cause a loss of DB...Unless like I said you add more cone area/power

truth.

truth.

what are you guys missing about me saying ''im putting more power'' ... im bumping it up to the full 1500 when the batts arrive. thats almost double. but will tuning to 34 kill me on DB's

I told you lowering tuning will NOT gain you dbs. When I say the only way that would happen is adding cone area and power I'm talking about A LOT of cone area and power. 12 15s on 5k can do good numbers all day at low tuning...but for your situation turning up your gains and using a lower tuned box is not going to gain you any dbs, as far as how much it will lose...Idk there is no way to calculate that.

Your going to lose dbs if you tune lower I can promise you that, even if you turn your gains up. Gotta make sacrifices somewhere

i cannot do that man,. i need to BR 39 class this year. :| so maybe 2 ap1500s? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif lol

tune it atlike 37 hz will have decent high tunning and wont blow up on songs with notes at like 35hz-32 hz

why should i believe you mike?

 

[brodeisel 10+ year member]

because all i speak is the truth

but wil 3hz make it that much different?

Wow, a car audio discussion in the t-dome, and its... staying on topic? WTF guys.

Some bad info in this thread. For example, much of the info on deviating below enclosure tuning. As we all know, an enclosure creates an 'air cushion' to help dampen cone motion. As the signal dips below enclosure tuning, this air cushion goes away relatively quickly. This is what is known as the sub 'unloading'. So, as that air cushion lessens, what happens? Cone excursion increases. When cone excursion increases, cooling improves, not the other way around. So knowing that, and knowing that impedance rise increases as the coil moves further and further out of the gap, it stands to reason that thermal power handling does not decrease as the sub unloads, it actually goes up a little. The problem with deviating below tuning to the point the sub unloads to a dangerous point is mechanical, not thermal. In other words, its more likely the motor will bottom out, a spider will tear, a t-joint will fail, etc.

Next, tuning versus output. Higher tuning does tend to increase output, but only at the peak output point. This is because most vehicles have a resonant freq somewhere in the upperbass/midbass region (say 60hz+). So higher tuning means you are aligning the peak output freq of the enclosure with the peak output freq the environment creates (resonating freq). Lower tuning tends to have a greater output potential across a wider bandwidth, which improves SQ for listening to music, but lowers the peak output which, again, is usually in the upper bass region.

The smell may be your coils overheating, or it may simply be excess glue melting away as you push your subs harder than normal. If that is the case is very specific to the exact scenario, and to say one way or another over the internet is simply a guess.

exact scenario? umm....

listening to katy perry-tgif (slams:fyi at 28 (full tilt)

and get done i have a bad bad electrical smell to the point where i pull over and look for fire on the side of an interstate.

now before this

going down a few roads listening to decaf at a low volume of 20-24 (i try ti hold my limits) and i will get the same electrical smell just not as strong.

do not want to get rid of my tuning because its so perfect. my personal hearing wave is from 34-90 with filters on. SS filter is around 32? ill have to check that but its so wide and being able to take your breath is

I understand. But we cant confirm a gain setting, inspect the speakers, or smell that dank smell for ourselves. Maybe you have a dead rat in your box, I cannot confirm or deny that possible scenario.

ok if i make a video of them getting the stanky leg

I'm tuned to 31 hz and my car is pretty **** musical. Idk where you're getting this bogus info that tuning low makes you not musical anymore.

And if you want a low and high tuning, build a box with a removable port.

being around SQ cars for a while. ... . and ive debated removeable ports but my slot is roundovered lol
