Re: Changing my mind - now want to build TC2000 LLT

I'm really getting frustrated. I used the values provided here and still get the "zero point" error.

I can't figure out what to do to change it.

Can anyone run this with a dual 4 ohm VC TC-2000 and as suggested: 320 L tuned to 14 - 15 Hz? I want to find out how long to make a 6" port, 7" port and/or 8" port. Then I can make the decision on port width based on what is available locally. I will make the ports flared with a router in the 3/4" plywood or MDF.

Thanks again and I appreciate everyone's patience.

320L and 14 Hz:

6" - 29.7", 210 Hz 1st resonance
7" - 40.7", 157 Hz
8" - 53.7", 123 Hz

6" is the maximum you can use.

Re: Changing my mind - now want to build TC2000 LLT

I gave you a link to that port Port Length Calculator. It will tell you how long you need. Just change the 320l to cubic feet which is 11.3cf and tell it how many ports you want and the ID of the tube. It will than give you the length for a desired tune.

Also heres a cool Box Calculator you can use to figure how big your box needs to be to get the volume you want.

And if your going the Sonotube rout heres a Calculator for that.

Thanks Ilkka. That should help me plan accordingly. Based on the size of my box, the 6 inch seems to be the choice.
