Ok so I just talked to the box guy. he said that the new box I want build is going to sound even worse then his, he also said the bass note was a 20hz its trying to play and its losing controle of the cone or something he said he would build it to make me happy but said it will not play the songs I wanted unless I had 2 subs or a 15 and that who ever said I needed a bigger port or box is talkin out there ass I of course put in that an ai rep said it was to small he then said what ever I want and will build it for free is he the one taking out his ass?

I'm not even sure I would trust him to build the box. Amount and size of a sub doesn't dictate what it will be able to play. For anyone wondering the box I designed for him is a double baffle 2.2ft^3 @ ~35hz with 34.375in^2 of port area.

He used to be the kob at one time till tommy came around and he kinda works for him now I have no clue how he knows its a 20hz note but yea bromo I have not forgotten about you I just have to wait for my bro I don't have a paypal and I was going to use his

The builder may be right in a way. Tuning low enough to play chopped and screwed music severly limits the type of music you can listen to. if you build your box to peak around 34hz actual tuning will be in the low/mid 20's with a roll of somewhere around 42-45hz. After that you will get very little output from the enclouser without adding power.

I currently run 15" DR's and love the way they handle the lows. I peak in the mid 30's and have had no problems what so ever with my subs being able to play that low with very little distortion. I would do something like 2-2.5cuft with a 13x6x24-30" port.
