I'm thinking of doing two 15" RL-p because of the low box requirement. My question is, how much does the basket/magnet assembly displace, per woofer??

Also, is 1800 RMS enough for a pair of these? Or should I step it up to 2500 or so?

Also #2, is 3 4" Aeroports enough port area for this install? I'm thinking I will have major port noise unless I step up to 4 4" Aeroports. Is 3 okay??

Thankyou!!

from what I understand, 1800 is plenty for a pair of RL-p's

fairly efficent by all accounts thus far

and I just updated your banner a little

The RL-p15 displaces around 0.21 cu ft of air space. 900wrms per driver is at the upper end of the RL-p's sweet spot. While they'll handle the 2500, there is no need for it and it will serve to put more strain on the driver so I'd definitely recommend sticking with the 1800 for the pair.

As to the port, I've never used those Aeroports but I'd go with 4 to be safe
