this will be used for home theater type uses, playing games, and listening to some music. I value sound quality over boomyness/volume. preferably good frequency response at low volume
I was planning on making the box small-ish as practical as space is at an unfortunate premium at my living arrangements around 2 feet in any one direction would be ideal but i can go a bit larger
* Piston Diameter = 266.7 mm
* f(s)= 29.61 Hz
* R(e)= 2.52 Ohms
* Z(max)= 42.07 Ohms
* Q(ms)= 3.676
* Q(es)= 0.674
* Q(ts)= 0.570
* V(as)= 39.600 liters (1.399 cubic feet)
* L(e)= 1.33 mH
* n(0)= 0.15 %
* SPL= 94.73 1W/1m
* M(ms)= 319.70 grams
* C(ms)= 0.09 mm/N
* BL= 23.99
*Xmax= 25.4 mm
Other info:
LMS coil technology 3" copper clad aluminum voice coil, single wind @ 2.5ohms, aluminum cone from a GZ plutonium sub, high roll rubber surround 12 spoke 12" basket, custom motor made from a 3 x .750" Y32 ferrite stack, TC9 T yoke with a full copper shorting ring pressed over the poll, TC7 top plate @ .500" thick (spec for LMS coil). Max power on that sub is around 600wrms but closer to 1000wrms
I think im on the right track? I am completely new to enclosure design

The ported response looks fine, as long as it is within the driver's excursion and power limits, and you are satisfied that the output is adequate with the power available to drive the sub.
The BR looks bad on paper and my gut tells me that the closed one is better.
Now, my EBP software recommendation is sealed (43).
Edit: anyway if used as a sub with it's own amp (BR) and not as a "stereo" the thing is different. More SPL on the lower end.
What's the name of the driver, if it makes any difference...

WTF?

the driver doesnt have any official name as it was custom made for me by a friend. those t/s specs were measured using some kind of measurement tool/software. i think he was giving a max power estimate. regardless at time of building and now still its irrelevant as im going to operate it with a 200w amp(an independant amp). im after signal quality at volumes that are acceptable to the neighbors not dB
only reference to a model is TC9/7/3hp-12-s2.5
sealed enclosure works very well for me as im nowhere near a carpenter, simple is good =)

A duct is not very difficult to put in, and can be sealed off with a block of hard foam (or a pair of socks
)if desired.The difference of around 8 dB at 20 Hz would mean the BR would sound more than twice as loud as the sealed enclosure down that low, where your ears are far less sensitive.
It would require about 1000 watts (and an 8 dB EQ boost) for the sealed enclosure to achieve the same level as the BR using 200 watts.
looks a lot like those
ill have to find out whats up with the t/s specs unless its simple to figure out. could have been a transcription error of some kind
its a little dirty as my life got busy the last few months and it was sitting around in a semi open box
all that ferrite makes it awfully heavy for its size thats for sure --
he sent me a spare spider and voice coil i could take pictures of or measure if needed/wanted but i doubt that'd be useful at all

What do you mean?!
Is it a DVC Subwoofer with a 2+2 ohm dual voicecoil connected in series or a single voice coil
Probably this is the measure of the cone (Surround/Surround) of a 12". Do you have a 10" or a 12"
Is this a 10" DVC Subwoofer with 10.10"/25.65cm Overall Outside Diameter
How much for the Sd parameter then.

Very likely the "frankenstein" driver got an heavier cone (319.70 grams) vs. 280g, only one coil of the LMS (TC Sounds LMS-R 12" DVC Subwoofer) (2.52 Ohms) vs. 3.96 ohms. The basket is a "TC9" type (TC Sounds Epic 12" DVC Subwoofer)
How much did you pay?
TC7 drivers - 12" 2567
What is a TC9 ?
