Box Design

[VicLS9898 0]

Ok guys heres the situation. I ordered a BL 15 with cooling and flat wind dual 2 ohm. I'm building a box myself and having trouble on what to do with the port. The box is planned at 3.76 ft^3 with the woofer displacement added in. Its recommended to have 12-16 sq in of port per cube so i need anywhere from 45-60 sq in of port. I want to just maybe slap a 3x6 aero port or maybe a 4x6 aero port. The 3x6 is 42 sq in and the 4x6 is 75. Both not in the range i need. Also looked on amazon and found precision ports 3 in and a 4 in round. Doesn't say the length on them tho . Reviews say there adjustable somehow. Help would be appreciated. Also wanted some recommendations on amplifiers. Was looking into maybe a rockford T1000 or a T1500 can get either for around $400. Let me know what you think guys. Thanks.

Should be able to find out which products you want from their site. They're adjustable because you can add a length of tube to a kit or whatnot, or cut a tube to get your desired length.

I would use the option with more port area, but if you can't afford it, then it's a sacrifice you will have to make.

Either of those amps will be fine, but i prefer some headroom so i would go for the 1500, especially if they're the same price.

Any reason why you have 2 exact same threads?

NOOB! lol

I would go with 2 6" aero ports, that would still be on the small side though, about 56.5 in^2 of port when the calculator i used recommends at least 62

get the t1500, just set the gains correctly

2 6" diameter aeroports, i didnt calculate the length needed but there are calculators for that, stefanhinote just made one on here for multiple aero ports
