Calculating Range Of Enclosure Frequencies


Recommended Posts

Is there is a way to tune your box so it plays a broader range of frequencies? Like from 28hz to 45hz? I understand big subs do better (have more authority) on the lows, and smaller sub are better for higher end bass. But is there a way to compromise for the size of sub woofers when tuning the box, so the enclosure can play more frequencies? Like if i wanted to go with 2x 15's, that i know will do well in the lower end, tune it to like 34hz... will it be able to hit the lows as good as some 12's tuned to 30hz because the 15's are bigger? if so, then it will also be able to sound just as good or better on the higher end bass, b/c its tuned higher right?

Also if it's possible can more experienced enclosure builders and designer's give me a specific tuning and the range that specific tuning of the enclosure will be able to play? I understand that all subs are not made equal, and sq subs will sound better then regular subs and what not. I am just a general estimation:

example:

12inch sub/ tuned to 32hz/ will play: 28hz-38hz

understand??

if not leave questions so i can be more specific when answering them.

you can see freq response graphs outside of car, and inside car... usually for a wide freq response, you will want to do a smaller, ported box, with a smaller port, but that is also based on the subs ability

I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

what exactly is that?? and where can i get one?

well, im leaning towards 2x type r 15's... i was thinking 33hz...

so your saying i should go with a smaller box, and a smaller port, but still tune to 33z, and that should give me a broader range of frequencies i can play right?

larger boxes, larger port centers more on tunning point

smaller boxes, longer port gives a wider freq range, less emphasis on port tuning

again, this is subjective towards the sub

If you got some sort of messaging program I can get you that on the low :)

Bassbox pro is a speaker box design program that has multiple parmaters for many speakers, or you can enter them in yourself.

my aim is: cpytrw
