DIY HT sub.

I'm thinking of going crazy with an HT sub project and while goofing around with Bass Box I thought, why not use a bandpass? If I design it with a pretty flat response from say, 20-80hz I don't see why it would sound bad...

What do you think? Gimme some input and tell me why this is a retarded idea //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

What's wrong with a properly designed and built 4th order BP? If he can build it properly, he'll get excellent results...

Ok here's the problem....

look here .......

I'm worried about the "cone displacement" graph. If it shows it going beyond the xmax of this sub does that mean it's physically impossible for it to produce that freq? to get it to all fit I have to reduce power to 50watt //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Who says he can't? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Transmission lines and folded horns **** if they're built wrong, but plenty of people attempt them as a worthy technical challenge...

To Beat: I wouldn't place a lot of faith in the Xmax graph...BP enclosures don't tend to model very well.

That's kind of what I was figuring.... It's going to come down to the proper port lengths I think.

i didn't say he couldn't, but it is difficult to get the results that you want
