View Full Version : 2 Alpine 12" Type R's...Which of these slot vented box designs for the most output?

05-09-2006, 07:35 PM
I plan on building a slot vented box for my two 12" 4 ohm DVC Alpine Type R's.

They are rated 500w RMS per sub but I plan on running 850w RMS per sub.

I like rap and like my bass loud,deep and able to get low (ground pounding). but I don't like it to sound distorted too much.

I guess I am more SQL but more SPL too.

I have been searching for box plans and cant decide between these three.

The reccomedations from crutchfield are 2 cubes per sub or 4 cubes total and the Manual reccomends 1.7 cubes tuned to 33 Hz ported each.

I have been told to go bigger so my options are 4 cubes,4.5 cubes and 5 cubes.

Which one will give me the bass I want and not sound like *** doing it?

What would the last enclosure design be tuned to? What program did you use to make the plans?

that plan is for 5 cubic feet tuned to 34 htz with 75 square inches of port area.

The last one is a 5 cubic foot ported box tuned to 34Hz.

I didn't design them.They are plans from the sticky marked Box Plans at the top of Enclosure design section (the section this thread is in).They are by Moe Lester.
