I have access to this pretty cheap speakers, and want to make subwoofer which goes really deep. I want response from 20 to not higher than 60 Hz.
What box would you recommend ?
Will I get less distortion if I put the drivers in push-pull configuration ?

Thanks !

If you want smooth response, 30 Hz is about as low as these will go. And that will be in a big, big box-about 7 or 8 cu ft.

The best you can hope for here is an F3 at 35Hz from a 4.5 cu ft VB tuned at 33 Hz. Almost any driver that you want to run strong to 20 Hz will have to start off with an Fs lower than that.

The exception is a horn-loaded cabinet, which this driver could take down to 20 Hz no problem. Got room for a 14 foot horn?

Do you have two?

Take a look at this coffee table horn (click 'plans' they are free)
