Here's what it says on the site.......

Optimal Car:

0.5 cu ft net volume sealed

0.3 cu ft net volume vented, Fb = 35 Hz

Is this right, or should it be the other way around? I thought more space was needed per sub when doing a vented box? I may be wrong, but I thought I would ask. Since my wife sub box is 1.3 sealed currently, I could just use a 3" flared port with that same box, and be fine right?

You're talking about the RL-i8 correct?

Correct I am, sorry.

As these drivers offer a relatively small cone size, I like to suggest a slightly larger sealed box in order to help beef up the overall output and low-frequency extension. On the ported box, this is not necessary and in order to maintain a flat frequency response, that is why you see a smaller net volume recommendation.

Apologies for the untimely reply! Spent a week in Oregon visiting my mother, sisters, nieces and nephews, and have been scramblin' to catch up this week. But I'm back, and as always - the quickest direct response will be had through email, though I will do my best to stop by these sweet digs as time permits!

I may just amend the recommendation to state 0.4 cu ft net volume, as really anywhere just under and up to 0.5 cu ft net volume will suit this driver quite well. Sealed boxes are indeed quite forgiving to minor variances in construction.

Thank you for the reply. I did end up porting the box (1.2cubes @35hz) to get a 139.6 at the dash with the 2 8"s. :woot:
