[QUOTE="CadillacMatt, post: 6938954, member: 595884"] It's funny you mention that I was thinking about that earlier... couldn't find anything on Google about it, I don't see why it would be so different from having one large port right? Just to split the difference between the two? Hmm... thanks for the input! edit: Just saw your reply about the aeroports 813thumper, I hadn't considered that but that would make things 10x easier... sitting here crunching a few numbers and this is what I came up with correct me if I'm wrong at all-- An 8" aeroport would give ~50in² of port area (3.14 x 4²) A 6" aeroport would give ~28in² of port area (3.14 x 3²) A 4" aeroport would give ~12-13in² of port area (3.14 x 2²) I've been reading that true flared aeroports require anywhere from 8-12in² of port area per ft³ of internal enclosure volume, compared to 12in²-16in² with a traditional slot port... and I've also read that one should go towards the higher port area side for more powerful setups... so following that theory, if the box's internal volume is say 6 cubes, assuming I chose to go with 10in²-12in² of port area per cube then the total port area should be 60in²-72in² respectively right? It seems that two 6" aeroports wouldn't be enough (56in²), two 8" would be way too much (100in²), would I have to do like two 6's and a 4 or some strange combination like that? Thanks [/QUOTE]
