Xmas remains under 20mm even at 2+cuft per sub and 2k WRMS total. I am not sure if Type Rs can handle more than 1k WRMS a piece for a long time. I guess I'd need to hear both setups to make up my mind. Thanks a lot for your help!

Didn't thought of making that comparison, thanks for the suggestion. Seems that the newer R Type is matching the curve (all things equal) at around 1.7cuft. That makes me wonder if increasing the volume to 2cuft+ would yield more dB throughout most of the Hz range or it will peak at a certain frequency? WiniSD is showing that it will increase dB without being peaky but not sure if that would happen in the real world. I can comfortably fit a 4.5cuft box for two subs, if that means I can get the most dB output at (high 20s - low 40s). Forgot to mention that my amp is Taramps HD3000, I know it's an overkill but I like to have a headroom and adjust the gain accordingly instead of running the amp to it's limits.

Hello forum. I am planning to pull the trigger on two Alpine Type Rs from the last generation. I really like the way type r's sound, because I used to have a SWR-1243D in a 2.1cuft box tunned to 33Hz, which I ultimately regret selling. The main question I have is about the enclousure. Specs say that 1-1.5cuft is the recommended volume for a ported box per piece. Isn't that too small? I ran a simulation on WiniSD and I could see that bumping volume from 1.5 to 2cuft increases output throughout the whole HZ range, wihtout making the box "peaky ". I know that there are way more factors than box volume at play and maybe these subs will perform better in a lower volume. My goal is to have a good output from 28-29 to low 40s, tbh I am not a fan of peaky outputs. I plan to run a single 6inch flared aeroport. Thanks!

Oh, definitely. I'll aim in the region of 8-900w for day to day listening.
Had to look up how to enter data in winISD as it was throwing me off. I got the t/s parameters from Alpine website. Should be good enough, although no two speakers are exactly the same.
