TC OEM 10" eclousre to drop low
 
I want to re-design my TC 10" OEM encloure to drop stupid silly low. I know the port has to be huge. Whats the right internal measurements for this design? Volume? woofer displacement?
thanks

you need to give a little more info.... power running to subs, the HxWxL you have available, even the specs for the sub would help....

come back with a little more info and you might be able to get the help you need...

Bigkahuna808 04-12-2008 02:51 AM

My bad on the lack of info. My Subaru wagon is small I think its 36" wide 16" tall and 34" deep.

The sub itself is Tc 10" oem dual 4ohms. 700 rms dunno the max.

I have 2 amps to choose from to run. One is a diamond d5 600.1 at 2 ohms the other is a mtx 1501d 1000 rms at 2 ohms.

if you want retarded lows a transmission line may be the way to go
it's not going to be able to take much power though...not on low notes any way

On my old slot port tuned to 38 I hit 139.7 Dbs on the tl. Using my 600 watt amp. I do like power but un this case it seems like I should be using that amp again. And not use the mtx for this project.

I had a OEM10 at one point. I remember TC advertising them as really small box lovers...good luck getting big port and tuning low with the recommended .5-.6ft^3 ported recommendation :( They were mainly bought as small sealed box drivers, or used with a TC passive radiator in a small box as well.

I used mine in .7ft^3 sealed....never tried ported, got stolen before I had the chance.

almond 04-12-2008 06:06 AM

actually they advised not porting it because of the huge peakey response. a huge low tuned driver would be the only way to get a flat response

Bigkahuna808 04-12-2008 04:48 PM

A huge low tunned driver? Are you refering to a large sealed box? If I go sealed I'm assuming that it won't be that loud?

I have a t-line box already for my mpyre 6.5x any idea how to design a t-line for this application? I found my t-line to be able to drop low but the 6.5s aint that loud. I'm hoping that by stepping up to the Tc if get better results.

I agree with Almond (I remember reading that as well) but would just rephrase that to low tuned enclosure, which is what I believe he meant... also, that driver meets the suitable requirements for a transmission line if you want to try it in one... for tline design clicky and read, read, read...

Bigkahuna808 04-12-2008 06:41 PM

do you happen to know the sub displacement so I can try design the enclousre? I do plan on going with a t-line so I can tune this low. Whats the lowest I can go without having the sub bottom out? I would like somthing retarded like 20 hrtz but my freind recomeded a 27 or 28 max. Same guy who designed my last t-line for my mpyres (27 hrtz)

what sould my internal volume be? and how long should the line come out to. i heard somthing rediclous like 80 sq inches

stovebolt6 04-12-2008 06:47 PM

they can handle 1500rms daily if your carefully with your gain settings
when sealed, idk if the same holds true ported.

any way on to ported i have sampled them before ported and they need a very long port to smooth out the response.

just to throw a wild azz figure off the top of my head (might be off by a couple of cu. ft. lol )

you would need around a 4 cu.ft. box with 3.2 cu.ft. just for the port

the coil will not bottom out with the way the are designed instead the back side of the cone will hit the top spider first.

and in larger subs with the same type of cone have been known to crack/rip the cone from the stresses of doing so.

with t-lines your suppose to make the length of the line in correspondence to the subs fs

Bigkahuna808 04-12-2008 07:29 PM

30 fs is what the sub is if im not mistaken. Is there a chance of me ripping the surround with a T-line enclousure?

So internal vloume is aruond .8 cube, with a 3.2 cube port? How big would the overall box be? would it fit into my area?

i'm decently sure he means 4 cubes in addition to the 3.2 cubes for the port :)

that was not an actual design that was just a ballpark figure to give you a idea how large the overall box needs to be just to physically port it to get a flat response. it was to help prove that it is impractical to port a tc oem they were never designed to be ported, and doing so they will most likely never perform optimally.

the surround is very unlikely to rip but as i stated before the cone is the weakest link on that sub.

use it as it was originally designed for, and it will last a very long time.
i say you keep it sealed, and send it a full 1500rms it can handle it.

Bigkahuna808 04-12-2008 07:42 PM

holy crap-o-la batman doesnt that mean its gonna be almost 8 cubes total? That box is gonna be massive!

Bigkahuna808 04-12-2008 07:43 PM

anything fancy I can do if build it seald to make it sound deeper or hit lower?

stovebolt6 04-12-2008 07:43 PM

no the sub only needs about .6 to .8 for ported but the port itself is going to take anywhere from 3 to 6 cu. ft.

Bigkahuna808 04-12-2008 07:46 PM

oh okay thats not to bad. Still big for a compact wagon. If I build this box in a t-line do I need to watch my power? With the mtx 1501d push it to hard?

stovebolt6 04-12-2008 07:47 PM

going off the specs it should be a fair candidate for a t-line.

you should start a new thread asking for a box design in the title.

and give your max dimensions, the sub specs, and the fact you are looking for a t-line.

and 600rms in a t-line should be fine for that sub.

i have seen them free aired with close to 1000rms ( i wouldn't do that daily though)

stovebolt6 04-12-2008 07:48 PM

if you can get a tapered t-line design you might be able to send it even more power.

Bigkahuna808 04-12-2008 07:54 PM

thanks I will go take measurements again to ensure I am right. Hopefully I can get something pretty silly fun going!

almond 04-12-2008 07:54 PM

i say folded horn :)

Bigkahuna808 04-12-2008 08:02 PM

I have a folded horn desgined by one of my other friends for my Diamond TDX 12" Havent gotten it installed yet, but Im expecting somthing pretty nuts. Hes a mad scientist at what ever he does. I would ask him for a box desgin, but hes in Japan right now.

We talked about the desgin before and he said the port on this sub is way big, and very hard to figure out. But the good thing is that if you get it right, it will play way low,
