I have been searching for a sub for some time now and have decided to build my own.I am a carpenter so the build will be no problem,i have all the tools.I have winisd,but have trouble using it.I have no budget so i am looking for the best build.The tc-2k seems like a great solution?i put the specs. into winisd and it came up with something about floating numbers and could not calcuate.

Does anybody have the numbers for port,volume ect....for this build?is this the way to go size matters little but med. size is good.my room is 18x15x10' ofcourse im looking for the low,low rumble/paint cracking bass during movies and also enjoy loud music.Im in an apartment now but will be moving soon to a house,so i cant realy crank it in thae apt..but still want some sweet bass.1,000 watt amps are fine +- also want to use hard wood weight is no problem.Alo what eq/berringer?ect what amp?

all input is welcome!!!thankyou

Which size driver...? 12" or 15"....

I personally would get the 15", as the prices will be heading north soon.
The 15" would be amazing in that small room.... If you do end up with the 15", get an amp that you can bridge to come up with roughly 2000 - 2500 wpc, and you will more then likely be not wanting for more in the future...

Did you look at the bottom of the page here... http://www.tcsounds.com/tc2000.htm

They have suggested enclosure and port info there...

Head over to the TCsounds forums or AVS DIY section for more help on box size and ports....

I just bought 2 of the 15" drivers 1 for each box, and will be pairing them with the 18" passive radiators. Im going to be shooting for roughly a 9 cu ft interior box size... They say you can go smaller..... The bigger the box, the deeper it will go...

I also am going to use double thick 3/4 ply and use hardwood on the outside... Looking for beauty... and don't care about weight... Great Plan...
Good luck...

Thanks warpdrv

the info will help!I guess i will buy 2 -15" one for spare or just to play around wiyh since prices will go up.Do i need an eq?or stick with just the 2500 wpc amp?any preferences on a strong reliable amp.
Do you recomend an external or a sealed amp in box?I have not checked the forums sugested,so all my questions may be answered!are you using the tc radiators?
thanks for the helpand good luck on that setup you are building i may try that one too.

I don't get my drivers until Tues. and I am getting my Passives at a later date, as they are not stocking them... I am using passives as an alternative to porting. Its an expensive way to go, I know.. but It allows one another way to adjust the freq. without making ports...

I am still learning as well on this project... I have previously bought all my subs, and currently have 2 SVS subs... they are pounding, but I was looking for a bit cleaner output, and more headroom.

As far as amps, there are alot of them out there.. depending on if your going to run 2 boxes, then you could go with a larger amp, and drive both with it, or you will be looking for 2 smaller power amps bridged. After talking with Kyle and Mike at TCsounds, these guys really perform great with alot of power... They suggested at least 2000 watts each.

My boxes will be a touch larger then an SVS Plus/2....

I would really be interested in how you design your box...

It is important to point out the original poster that one will need a dedicated 20 Amp 120VAC power circuit for each amplifier with that capability.

I hear this 20 amp fuse issue allot. I'm not convinced. I would rather be corrected however if I am wrong.

I used to go to tons of basement house parties with a DJ lights full sound board and well into the 3,500 watt range for full range and subs. It would have a much higher constant draw than just a sub.

They were just on 15 amp, heck one was in an apartment.

I know nothing about that portion of electricity from the wall so please let me know why you suggest that 20 amp?

It is true: one would not likely trip the breaker, even with 2x 2000 watt pro amps driving the subs during normal use. However, it is also true, that one will not likely use 1/20th the output that this proposed set up ( 2x TC Sounds 2000 in large ported enclosures) can produce in normal use. The only time one would run into possible breaker tripping is when playing constant test signal(like a sine wave) and pushing to limits in order to 'show off' and/or measure the maximum SPL capability. The breaker is going to trip under those conditions, if one actually tries to reach the output capability of 2x 2000 watt amplifiers on a single standard 120VAC line. Even if one used two lines, it is not likely maximum power of the amlifiers would be reached, due to line voltage sag. To get around that, the amplifiers would need an internal regulated PS. I am only aware of very expensive amplifiers offering this feature.

Average actual power used in normal applications? Probably 40-80 watts. :)

Chris you the man. I think you have posted that before and I asked you the same thing. I apreciate your patience and knowledge!

hey guys

I just purchased 2- tc2k dual voice coil subs,I had to act quick before they go up in price.
They were supose to mark them up yesterday.i paid 275.00 a-piece just now.im going with a crown or a ep2500.do you recomend running them a 2 oms or 4 ?I need the max power i can get out of them.

thanks

BTW, I have some Crown XLS amplifiers. The Behringer EP amplifier appears to be made substantially better, in pretty much every regard. Better(heavier grade) chassis, superior cooling system, better quality PCBs and higher power output. The Crown, however, has a far superior warranty.

no. 5

For whatever it's worth, though, the XLS series is not spec'd for 2 ohms like the EP is.

Thanks no5 it good to know.
how reliable do you think bridging two ep2500 would be.Will that take some stress off the amp?I know they are reliable,but do the heat up?When running at 2ohms vs 4?

thanks

Seriously, what stress? You will probably be using around 30-40 watts on average in normal use. If you want to do something unusual such as have a continuous 130dB output in your room, you may stress the amplifiers (and your building structure ).

Just for giggles, here is my last project. It by far destroys all my other projects in respect to overall size. After it is all said and done, calibrated and +2 dB hot:p, i found myself having to put foam gasketing on the doors within a 4 room radius of my theater room... For the money, can't hardly beat it. A ported sub may be louder but zero port noise is purty.

Great job bmccord.... looks fantastic....

Im really looking forward to getting my dual subs built....

I have decided, that I will order 2 more 18" vmp's... to go with my 15" tc-2K's..

Have to contact TC-Sounds in the morning....

Could you pass on the dimensions of your box... to give me a grasp of how far apart I have to set my VMP's....

Looks great...

There is a clear, sorta, Autocad plan in the center of that picture;)

Yeah I saw that, just couldn't read it very well..

any chance to get a better looking copy of it?

Looks great... how does it sound...?

Yeah, I will PDF a large res image of my AutoCAD plans (when architects design their subs:p).

As for the sound, I love it. I am actually working on designing another one utilizing the 18" TC-5200 and two 18" passives.

These are power hungry units. I have a single Behringer EP2500 powering the sub right now but I can get it to clip at high excursion/ high SPL occurrences. I have it wired at 8 ohms right now which is pretty weak but due to the old VC configurations, the next step down would be 2 ohms and that would tax the EP2500 (i think). To remedy this, I will be running a second EP2500 and run 2 voicecoils per amp at 4 ohms. Should be plenty (around 4000 watts:cool:)

I think you may be ok at 2 ohms considering you won't be running all the watts verry often at that level. But it will extract every little drop you can from the AMP. I think it would runn better than you have now, you could just limit the gain on it. Then again... I like more power to me that is sexy.
