k i got 1 12" type R and I just got the
Bass Soundcheck 1.0 today, but before i play it i would like to know, will it destroy my sub?
i would like to thinnk not but i want to be sure
hmmmm.... I am confused, and the Blonde genius that is me,
does not easily get confused
I am guessing you are going by a warning label on the CD or something.
Caution may cause damage to speakers.
Ask yourself these questions and you should get your answer.
1. Is my amp pushing over 300 watts rms? ( Type R 12 is 300 watts rms and 1000 watts peak.) Peak is not jamming it for a minute. Peak time is an instance.
2. Is my amp crossed over ? ( Type R 12 Frequency Response is 24Hz – 500Hz anything more or less could be harmful to your sub.)
To help you out on this i can explain how the sub works. For a note to play 1 Hz it makes 1 cycle per second. A cycle is the sub pushing out and back in. So if the can not handle 2000 Hz it will over work itself and blow even under rms watts.
As long as your amp is tuned correctly, you will not damage your subs, regardless of what frequencies you send to them. The frequency range of a speaker shows what the speaker will play, if you send it something outside that range it simply will not play those notes. So as long as the amp is giving the subs a clean, unclipped signal you'll be fine.

Besse so what your saying is all speakers have a built in crossover in it that will only let it play the Frequency Response that is stated in the manual stated by the company that makes it.
Lets do a test on
YOUR tweeters or mids. Bypass all crossover points and set all the amps to full range. Turn the bass up on your stero and play the rms watts. Tell me what happens.
tweets are different than subs or mids. i have played my sub without any cross over for a while (this was before i knew anything about audio), and it still works fine 2 years later.

a sub is gonna play whatever signal you give it....if you send 10hz to it, it's gonna move, you can count on it.

what if he has a vented enclosure tuned to say...45hz, and he plays a 20hz test tone with no subsonic filter..he still gonna be fine? answer, no!

True, true, vented box is a completely different story, sorry I missed that.

yes i was going by the warning label on the cd
and the type R, well my type r has a rms of 500 and a peak of 1500
i have a pioneer monoblock thats putting out 800 peak i belive and my box is vented and custom built, i do not know the specs but thats becasue i didnt design it, i just built it. lanman3317 designed it
thats the box, maybe someone can tell me what its tuned to?

anyone??

If you have a subsonice filter and your gains are set correctly you'll be fine. What model is your amp?
09 HHR LS, Wife's Car
05 Cavalier, Clarion DXZ375MP, Autotek MM8000.5 & 13Kv.2, wife's old car, updates coming soon

That would be kinda funny.

We need to know how wide the port opening is.
and also if those are inside dimesnion or outside.
well...by my first calculation wtih the port volume...the box seems to be around 1.24 ft^3 which right off the bat seems pretty damn small for a ported enclosure. The port area seems to be about .26 ft^3 which makes the actual box just under 1 cu. ft. (this based off of internal dimensions of W=18.5, H=12.5,D=9.25 and the port being 2.5" wide, I also didnt take off any vol. for the port material)
Am I wrong?

oops^
Anyways...with a 1ft^3 box and a 13.75 port length, 12.5 height, and 2.5" width I get a tuning freq. of 65.5 hz. Am I wrong? I've been trying to practice my calculation for when I start building my "keper" box..lol.
Is this supposed to be a strictly SPL box?

i have the GM-7100M 800 watt mono block

those are outside dimensions
the pic there has a couple wrong dimensions so thats not exactly accurate. But its very close
the inside of the port is 12 1/2 by 2 1/2
as far as spl idk, he designed it by the types of music i listen to, rock, rap, techno, country
hmmmm.... I am confused, and the Blonde genius that is me,
does not easily get confused
but according to the specs vented has to be between 0.75-1.75 cu. ft. and sealed has to be between 0.7-1.0 cu. ft.
its closer to 1.75 but im not exactly sure and it is vented
hmmmm.... I am confused, and the Blonde genius that is me,

ok so i just looked at the amp one more time, and i noticed that i didnt have a subsonic filter, just a lowpass filter. that is set at 240hz IF THAT IS WRONG PLZ DONT FLAME ME!!! if it is can you jsut tell me what i should set it at. the gain is set at 3/4 because i had a problem with my alpine deck and ihave to run the sub off the back speakers of my car. thats what i was told to set everything at
hmmmm.... I am confused, and the Blonde genius that is me,

My bazooka tube's built in crossover goes from 18-205hz. I have it set around 200, it sounds much better there than it did at 250, but it all depends on the sub and your taste.
the crossover should be set to 80Hz
there is no one answer for where a crossover should be set. but anything over 75hz can be localised meaning u can notice where the sub is located. i run my subs wherever my midbass cuts off. even a cheap componet set should be able to play down to the 80hz range so your bass should be set somewhere in there. i try to run my subs as low as i can while still getting an acccurate sound.
