In this car audio school I been going to the teacher said the rule of thumb is to tune 10 herts higher than the subs frequency. Is this true? thoughts?

Yep exactly

Yeah there was alot of stuff that I didnt agree with him on, but he also taught me alot of **** though. We would get into arguements all the time lol. Also they got me to pass the mecp test.

well a 54 htz box may be good for SPL with a particular sub and/or vehicle but for musicality...it will blow chunks

well actually he will just go off the recomended by the specs. But thats what he said though. So now someone tell me the correct way to design a box.

this one dude had some db drive subs, they were rated at about 300-400 a peice, and with the box he made in that class, it literally sounded like ****. It was tuned around 40.

well i'm sure the manufacturer knows what they talking about. But you can fudge the numbers to get more output, lower notes, etc. It all depends on what you expect out of the box.

exactly this is what I strive to know. Some expert box builder on here has got to tell me their secrets.

I don't want to make any hasty judgements but your teacher doesn't sound that knowledgable. There is no hard and fast rule in tuning--you can tune above, below, or on the Fs of the driver. It depends on your goals, on the application, enclosure size, the driver, etc. There are no secrets, but learning how to read T/S parameters, learning about how speakers work and how different characteristics of drivers affect output and how different characteristics of enclosures affect output will help you.

Tune to what your ears or the meter likes.
