View Full Version : Aeroport Question.

I know this question has been asked about a billion times but forgive me as I've searched and searched and still cannot find a definitive answer for my situation. I know that with an aero u can cheat port area and I suspect too much port would cause unloading issues. Im building this time for 4 Sundown E8v3s on my Ab ph4000(tad under 2k). I have modeled the subs and found a liking to 2.5cubes at 39hz but heres my question. "Will two 4in Aeros be too much, enough to cause any suspected unloading or any other issues?" The way I see it, thats 10in per cube. These subs are rather beasty and boast 12mm xmas so I wonder if a lil more port would hurt or affect overall output? Below are the T/S specs. Thanks for ur time and any opinions.

300 watts RMS

I'D look at one large port as opposed to 2 smaller ones.
