With the suggestion by Exocer, here is my sonosub thread. :cool:

Here are the particulars:

One TC Sounds TC-2000 15" SVC.

Powered by a Buttkicker power amp.

In a roughly 320 liter sonosub (after subtracting driver/port volume), using 24" sonotube.

Tuned to ~14.6Hz (subject to change) using the soon to be released 6" port flares from Precision Sound Products.

The interior will be lined with 2" Wedge foam. I already have quite a bit of this left over.

Here is a simulation of the design:

http://i27.photobucket.com/albums/c1...C-200015-1.gif

The final updated ETA is October, 21th.

The bottom endcap assembly is almost ready to be painted. Today I will be making the cutout for the port on the top endcap assy. and I'll be gluing it together. I'll probably start putting some primer on it as well since it is a good day to paint.



I will be happy to answer any questions or take suggestions.

Will :cool:

Wow, sound fun. If you have time, maybe document your project step-by-step? I did not have a chance to take pictures of my project step-by-step, and plus I'm tool limited I have to do things the hard way. I'm excited for you. I'm sure you will like the outcome of this monster. Have fun and use your tools safely.

Al,
I will do my best to take pics step-by-step. :)

I am also somewhat tool limited. Don't have a plunge router (just a fixed-base), but it shouldn't be too much of a problem. As of now I think I might just cut the plugs a bit large with a jigsaw then sand them down to a perfect fit.

What's the end cap situation going to look like, three 3/4" layers on bottom and three on top with a flush mounted driver? Oversized baseplate? And are you going for all black? This is gonna be a pretty nice sub :)

Man, my TC2000s look so good that it would be a shame to hide them in a downfiring Sonotub ;)

Good luck to you, as you know I was building two of these before I designed to go the IB route.

Yep, 3 3/4" layers on the top and bottom, with the driver being recessed by roughly one layer.

Baseplate will be oversized a bit, yes.

And all black. :)

Haha. Do you have any idea what I am coming from? I basically have no sub at all. :p This will most likely be my main sub for the next 4-5 years, or until I build a house. When I do that, I will design it for an IB from the getgo.

Believe me, I'd rather not hide it either. However, I definitely don't feel like building a massive MDF box when I could more easily build a much lighter sonosub.

I am following your IB thread as well. :cool:

Willd, I see that you will be using the Buttkicker amp. I just want to point out that it is 1100 Watts @ 4 ohms and 2100 Watts @ 2 ohms and the Res of the TC-2000 15" SVC is 3.19 ohms. So I'm guessing, that you will be seeing around 1500 Watts. I just want to give you a heads up that your design will now no longer be amp limited, if that was your original plan.

Hey SteveSub -

Actually, the Buttkicker amp was measured to put out 960W @ 4ohms, RMS.

And the 3.19ohms is the DC resistance. As TC Sounds states:

Quote:
The nominal impedance, or the load the amplifier will see while in operation, will be higher than the DCR by factor depending on the frequency. You can safely add 30% to the DRC for the estimated nominal impedance.
So in real world applications, the amp will really be seeing a nominal 4ohm load. I took this into consideration before making my purchases. :cool:

I appreciate your concern though. Thanks a lot!

Amazon.com for $252 shipped.

There are only two left. :eek:

Tigerdirect has it for $239, but then with shipping and tax added, it ended up being ~$10 more than Amazon.

I was only off by 540 Watts :o Great job on doing all your homework before building. I was considering using the EP2500 for the same driver, and assumed it would be closer to 900 Watts instead of 750. I haven't purchased anything, just modeling different drivers with different amps.

Did Precision Sound Products give you an eta for the 6" port? I know they are ready for preorder. Hopefully you will get them around the same time you get your driver.

We all make mistakes, and I will still make quite a few before I am done. :)

The EP2500 would still work quite well. Ahennings uses one for his dual TC-2000 sub.

I would definitely go the ep2500 route if I was planning a dual sonosub setup.

Yeah, I contacted them the other day. They said "We should have them in the next 2 weeks." and that was on Monday the 18th. So in reality, the ports may the last thing I am waiting for. I ordered the TC2k today, but I dunno when TC Sounds will ship it. Hopefully I can still make my original ETA.

Hey Willd,
I'm really looking forward to your Thread and progress. I'm absolutely sure your going to churn out a very nice representation of a LLT! Everything sounds good except for the fact that your not using a plunge router, but since your building just one (which is plenty) you'll be able to work around it's limitations. Anyway I think it's a hoot that your going to build one. The Brotherhood rejoices :)

Shoot yeah, I'd love to have a plunge router but I should be able to make do. :o

I feel like I should put some kind of mark on my sub pertaining to the Brotherhood. Hmm.... :cool:

Roadtrip! :D

I definitely don't mind sanding, and that is currently what I plan on doing (cutting the plugs a bit large, and sanding them to fit tight).

How big is the baseplate on your 22" sonosubs? I was thinking maybe 25" or 26" would be a good size.

No I went 24.5" on the caps including the baffle face. I needed to think what would work best with a single sheet of MDF and shipping constraints. When I sit back and look at the proto, it's as wide as I would have liked to go anyway. You might differ, but going to wide on the caps could get rather gaudy pronto quick.

So your baseplate is equal in diameter to both caps?

What length dowels did you use for the baseplate to bottom endcap? I was thinking 4".

I have mines as 24.5". Good luck sanding :p I hope you wear a dust mask.

Yeah, I've worked with MDF before so I know what to expect. The weather has been excellent the past few days. I'll probably do most of the work in the driveway.

No kidding man. This sub is the realization of months of reading/research...or mostly procrastination. :D

I can't wait to hook it up and try out a bunch of movies to see what I've been missing. Willy wants some clean, effortless, deep bass. :cool:
