need a box design for a Single sealed 12 HT box


Recommended Posts

hello SMD im in need of a design.

i want to do a single 12 in a sealed box. its going to be for a home theater project. Its gonna fit a single 12 infinity kappa perfect and a dayton 240 watt amp. Sub needs about 1 cube and the amp displacement is 8.5 x 8.5 x ???

not sure on the depth, parts express says its 5 inches deep, but not sure if that is the whole item (heat sink fins and all) here is the one im looking at : http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-804

i would like to do a down fire with the plate amp on the back.

thanks.

I have that amp, and it just doesn't put out the power you want sealed

in a ported box, you may get better output, but even free air you will only get about 1/4" of excursion if that.

I got lucky with that amp and a 18" I made that just had super soft suspension.

But bottom line, that set up, I would do ported, and tune it low

I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.
