I think ill tune to 30 hz. I have access to a 12db per octave subsonic filter. What should I set it to ( 20hz 25hz 30hz 35hz)?

Thanks Mike. Last question and I will be out of your hair. Will SQ suffer with this tunning of 25 hz? Will their be a flat response curve?

oh yeah I ment the RL-p 12"

I would prefer the low port tuning because I listen to music that reaches as low as 17 hz and I would like a very flat response curve going down to the 20 hz range. I want the port to be able to control the sub at very low HZ. Plus I lack a sub sonic filter. Add your toughts on performance at 25 hz as compared to 32 hz?

I am about to pay for my RP-i 12 " sub so it can be shipped. I want to build a ported box and tune it to 25hz. I will be pushing 600wRMS to it. What size box would be best? Also feel free to offer any other suggestions. Thanks

What is the "correct enclosure"? Also, I checked out the response curve on this and was surprised that it drops off so quickly. How is the bass output from 20 - 40 hz?

I have 550-600 RMS to deliver to one of the two subs lsted in the title (RL-p or RL-i). Will the RL-i be over powered at this? I would prefer to get the RL-i. Let the opinions begin...
