View Full Version : Infinity 12inch 1220W Bandpass

I wanna put my 12inch infinity in a bandpass box, I have one of them for now, but may be getting another one, depending on how the 1 sounds in the box.

I read some specs online for this bandpass, and it seemed a way out for me to beleive...:

"The recommended bandpass enclosure has a sealed chamber volume of 1.25 cu/ft, and a ported chamber volume of 1.25 cu/ft (2 ports: port diameter: 4", port length: 8", port tuning frequency: 62.6 Hz)."

Thats 2.5 cu/ft for one 12? :p And the tuning freq is kinda high....well atleast I think so...

Any suggestions?

Just incase you need to know, I have a Premier DEH-740MP HU, a pair of 6x9 and a pair of 5 1/4 pioneer mids, the infinity 1220w, an 800watt kenwood amp for mids(cant remember the model), and an Alpine M350 for bass amp. And this is all installed in a '94 civic.

so what would you suggest? Sealed?

The specs I got for a sealed box ws 1.25cu/ft, but I am not sure if that was for 1 woofer or 2 ??!

Sealed @ 1.25 cubes is too big but a 2.5 cube bandpass is not???

Just so you know the tuning freq on the front chamber of a bandpass is supposed to be the middle of the passband.

well the 2.5 cube bandpass is to big...have to forget about that shizzit :P

What I meant to say was I would have to go with the 1.25 :)
