I'm in the process of building a set of 4 RL-p15 d2 subwoofers (6.5 cubic feet, ported with 6" aeroports and tuned to 18hz) and was wondering if using felt pad in them would be appropriate (and why) or if using a cheap acoustical foam would be just as good.
If the felt is the way to go which SAE Grade No./Thickness should I look at? (Looking on McMaster-Carr website) and approximately how many square feet per subwoofer should I use?
Thank you.
