My sub is a custom job built off a TC Sounds TC-9 Motor.

I was hoping Winisd would at least have some TC Sounds subs but it doesn't. frown.gif

I was going to just build a completely cubed box with all sides the same dimensions but after playing around with WinISD I noticed the different dimensions it suggests for different setups.

I know there's no way to know what my ideal set-up would be so is it ok to just go with my original design?

Driver is a 33lb 15" being powered by 1400 watts.

I was planning on a 21" X 21" X 21" sealed enclosure yielding 4.2 cubic feet.

Yes You can if you have them the T/S Paramaters of the driver input them into WinISD and they will calculate a Box size according to the T/S Paramaters....With custom boxes they are usually pretty big or it is more desired to have a bigger box..

Win ISD PRo should have some TC Sounds Drivers??

just based on the description of the tc9 series:
http://www.caraudio.com/forums/general-discussion/500819-tc-sounds-motors.html

with 37.5mm excursion, your plan sounds fine, but without t/s specs that is just a 'best guess'.

for some reason, my gut is telling me to go just a little smaller, but that is just a gut feeling.

Listen. It's All Good.

Can you post a picture of the cone and the basket from the side? Is the spider black with the leads sewn in? Once we know that we can see if it has any of TC's soft parts on the motor, othewrise the specs aren't going to do you much good.

Doesn't look like any parts other than the motor are TC.... I would be willing to bet that the coil is thinner, and likely less motor force. If you are planning on building a sealed box, I would go probably 20% bigger than listed... so possibly close to 5 cu ft.

Yeah I'm looking at doing a
18" W
24" H
24" D
for a 4.8 cu. ft yield.

Yeah I'm afraid I may have gone too big on the box.

The finished box turned out being

19.5" W
24" H
26.25" D

with .75" MDF walls and a 1.5" front baffle.

If my calculations are correct thats 5.6 cubic feet. I hope it sounds decent. I will be powering it with a Crown XLS 2000.

Just take it easy on the volumes at first until you are certain you aren't going to hurt it. You can always add solid material in the box to reduce volume, like gluing in a couple of 2 x 4" chunks.

Do you think maybe using a smaller amp would be a good choice, maybe the XLS 1500?

Sorry to resurect this thread, but I have a TC9 12 and I'm wondering how this turned out. I'm going with a 2.5cu ft Net ported box. I haven't picked out an amp yet. How is the Crown amp working out for you? If you went with the XLS2000 and it puts out the advertised power. I bet you don't have the gain turned up much past the quarter way as it doesn't take much wattage to get these very well built overhung motors to moving. Especially since your voice coil was replaced. Pretty large enclousure for being a sealed box. A bigger box deceases power handling also, so I'm wondering if I need to make my enclosure larger if it worked out great for you. If I go with a Crown, I'm getting the XLS 1000 or 1500 only because my sub is a Dual 4 ohm so I either get a final ohm load of 2 or 8 ohm and wanting to throw 1000wrms at it and tune it to roughly 20Hz. I'm also looking at the Behringer NU3000DSP iNUKE

Not sure if you know how your subwoofer was built or not, but what could possibly have been done was with a lighter coil which decreases power. How much is depending if it is with a CCA or OCA Voice Coils. I just wonder if the spider packs had been replaced with stiffer ones and/or had some added, which would then increase the power handling. My four Sundown Audio SA-8 V.2 Stock SPL 8" subwoofers were done just like that when I had them completely gutted and replaced, but they added 2 more spider packs. My power handling went from 600wrms to 1kwrms. I still haven't even heard these yet as I haven't installed them in my new truck. I've had them for a year.

Hope it turned out great!
