Would this sub be suitable for dipole or horn loading or both?

Hi, I'm trying to determine my next insane project to do. I'm thinking of buying 10 of these woofers. I'll probably use them in a variety of configurations to play with- I want to try normal direct radiating, horn loaded and dipole, as well as to try 10 (or as many as I can fit) in my car.... What do you all think of these specs? Its a 15" driver, do you think I should go with the 12" version that has similar specs instead?

If you want a REAL project think big. Forget your car. Buy a used school bus and all of the drivers that dealer has, get all the 12"er's and also the 15"er's just to be sure. :bigeyes:

Oh and one more thang, don't be driving that rig anywhere north of lake ontario thank you very much. :att'n:

Fine for dipole, so-so for BP and BLH. What size/quantity you use depends on the app's size/performance goals, so it depends.

What is BP and BLH? Bandpass? Back loaded horn?

You know what, that is my ultimate fantasy haha. I have always wanted to do something nuts like use a bus or a limo (or a hearse) and fill it full of woofers! :bigeyes:

If it is so-so in a BLH then it will be so-so in a typical BW FLH. An optimum one would have a ~10Hz Fc and be done by ~100Hz, so unless you have a basement you can convert or are willing/able to attach a concrete horn to a side of your listening room.......
