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!
