Default Recommendations for subwoofer

Hi all,

I wondered if any one could suggest a driver to use for making a subwoofer to plug into my sharp mini hifi. It has to be realitivly cheap and i will model it in WinISD. I was thinking of using an 8" driver in a vented enclouser or maybye 2 8" Dayton DVC's in isobarik in 4th order bandpass configuration. Any help apreciated

Greg.

How 'mini' is this mini-hifi? You're only getting to about 80Hz on the high side of the bandpass, so you're system will need solid extension down to 80Hz.

Bandpass boxes are notoriously tough to tune as well. Its highly unlikely that you will get good results if you build exactly what the modeling program tells you.

I will be powering it with a sperate amp. I was looking at the maual for the mini hifi and it says the the subwoofer output is it at 70hz no i dont know if this will be enough for low bass.

Well if cheaps your game, then I suggest a Sonotube. Go to home depot look in the concrete/roof section by the lumber (usually), and look for these cardboard cylinders. They usually have 8" and 12". Buy the 12" one (usually ~$8), and then go and find the "smaller" sheets of plywood/mdf (usually 2'x4' sheets), and sometimes they have 12" MDF circles for like $5.

Anyways the whole point here is that you can pretty much piece these all together, and have a cheap effective sub. And don't freak out that the cardboard looks thin. If you brace it...especially a MDF ring in the middle...it is very very sturdy, as a cylinder spreads the stress over the entire circle. You will be amazed!
