any ideas for a slot port box for daily listening anyone?

ive heard 1.0 cu.ft tuned to 40hz but i wanna be able to stick 600-700rms on it so i was thinkin maybe .7 or .8 cu.ft after displacment tuned to 35-40hz??

Someone on here did a 6th order for one and said it worked great. Normally subs that do good in ported boxes also do well in 6th orders. Subs that work well in sealed boxes also do well in 4th orders.

If you want to go ported they can handle 600-700 watts in a 1ft^3 box. Tune to 35hz and you're set.

ram can u explain to me why in the heck i cant keep it bottoming out on 400 rms? its fine on 200rms and get surprisingly loud & low for an 8". I have the subsonic and everything set right...maybe i screwed up my box design the first time around..? ( 1.0 cu.ft after displacement tuned to 36-37 if i recall)

Which frequencies does it seem like it's bottoming out on? It could be a subsonic thing, or you could be sending more power to it than you think. What amp are you using, and is your sub have D4 coils? What are your box specs, like overall dimensions and port dimensions?

How was he being a smartass? Seems like he was just saying that it's what DD recommends, nothing more. Now if he had said "hey douchenugget" to start off the post, I'd see why you're being defensive.

pushin it with a little cheap soundstream i had layin around...i think its rated at 500rms at 2 so i just said 400 cuz it could be a little overrated.
