    Looking for Box Design Help!

    I have a 02 Trailblazer LT and I would like a low slamming box for my 18" BTL N2 Fully Loaded running off 2000w.
    I'm currently running a 30hz @ 7ft^3 box but the port area seems small its like 11inches per ft^3. I used to run a 6.5^ft3 @ 30hz box with 15inches of port per ft^3 and it slapped lows I want similiar with a KERFED port.


    NOW THIS IS WHAT I WANT!
    I wanted a KERFED design for a low slamming box max dimensions are: 43w x 18h x 30d
    Needs to be 28-30hz @ 7ft^3 and I want around 14-15 inches of port per ft^3 I need a picture/cut sheet and information on the kerf cuts. Anyone who does this I can pay 5-10$ USD but it MUST be a good box builder such as Rabbit etc.

    LMK PEOPLE WANNA SLAP LOWS.

    Never quite understood how with more and larger woofers, such a big port could be used with a short length and reach low tuning?

    That tunes @ 44hz I believe. Tuning @ 30hz is really silly if you're not using it for watching movies

    Unless he can set the SS around 35hz that BTL would go mechanical fast. He said he wanted lows.

    But why would he want to tune to 44 hz if he's building a system for the lows?

    I don't see that 44 hz tune playing into the low 20s very well

    I thought he wanted to get loud. He can play low right now and the only "music" that really takes advantage of that bandwidth is test tones and crap slowed to half speed.

    Pretty sure there's a 27hz note in On My Level? It's surprising how many newer rap songs I've been hearing bass notes that I'm pretty sure are in the mid 30's.

    This is where I was confused.
    This is also why I am considering keeping two demo boxes around. One for DD, tuned up into 40-42hz, and one for lows and demoing rap, tuned at like 35 33s.

    Then again with how my system was hitting last time I played with this 35 box if I break 1000w kind of feels like a 35 tuned box can take care of anything up until 60s 70s adequately.
