question on porting

[lithium 358]

my friend is getting a 10" type R (powering it with a kicker 400.1). he's trying to keep the box as small as he can so i was thinking about using a flare tube port for the box.

what diameter should we be looking at?

any suggestion? (sub isnt purchased yet. but i havent seen anything better for 100 bucks shipped)

edit: damn i think i put this is wrong section... please move if it is

10" sub? 3" port should be sufficient.

would you notice a increase in spl if he went with a 4 inch port or bigger (tuned to the same fs). the manual for the type r states a 3.75 inch port is recommend. is the idea behind the flare port that you can go smaller on the diameter and keep port noise down?

all i know is that the type R is a FINE sub...

What? SPL? is he going to compete?

by spl i just ment if there would be any NOTICEABLE gain in loudness with a larger port area vs the recommended?

also, would a flared port have any advantage over a regular round pvc port w/o flare?

i dont think you would notice a change.

big time air flow is way better with a flared port and you can see the advantage when you get metered lol.

i dont know if you know about psp ports i dont remember their web site but i think someone on here knows what im talking about and will be glad to post their web link!!

um i think it something like this hahah http://www.psp-inc.com/

and is you want to keep the box small go with flared ports from psp... i have used them before and they are great...

they also have less dislacement so the box can be a bit smaller than a slot ported..ect
