    Port or Seal?

    Okay, so my 12" type-r's should be arriving soon, and I just can't decide whether I should get a sealed box or ported box. I know that they would have pretty good sq in a sealed box, but I would also like some spl. Would porting the box be worth it? Or would I be sacrificing too much sound quality? Let me know what you guys think. Thanks.

    How would a ported box be sacraficing sound quality? Most of the recording studios use ported boxes. Sealed is much easier to build though.

    cause the ported moves more air resulting in a higher sound pressure level. so this will sacrifice sound quality. i think that you should go sealed in this case. those type r's will still hit hard even though you're using a sealed.

    when you try to get high spl out of a sealed box the increase in woofer travel (xmax) will cause distortion. A ported box can produce high output with very little xmax above the tunning freq.

    A good ported box can provide clean, high output down to 30 hz @ -3 db. A sealed box will start to roll off around 50 hz and be -10 or 12 db at 30 hz.

    ported

    If you have a correctly tuned box and a box that is large enough, your SQ shouldnt take that much of a hit. However if you do not have these, it will sound like crap.
