I have a 25 watt subwoofer from a home theater system and im wondering if theres a way to make it more powerfu

Question

Like opening it up and turning or adjusting something to go beyond the limit

Answer 1

ye add some base

Answer 2

better amp, bigger box, bigger subwoofer. Unless you want to blow it.. dont push it.

Answer 3

NO, there is no way to increase the "power" of your 25w sub-woofer! If it's inadequate, and I'm sure it is, you have to upgrade considerably to get the improvement you are looking for.

Answer 4

Technically, you can most likely increase the SPL of the sub. However, unless you have the T/S parameters of it, it is extremely unlikely that you will get the results you want.

I have designed and made plenty of subwoofer boxes back in the day. Most drivers, but not all, can be put in an array of different box types and volumes to change their frequency response characteristics. Usually, home theatre subs are forced into small, ported boxes which gives their frequency response a decent size hump near the resonance frequency that then steeply declines. It can't be helped unless Newtonian physics change. That being said, if you know the T/S parameters, you can usually build a box with a larger internal volume that will go lower and produce a higher SPL. A good program for this is WinISD.

However, if you can't find the T/S parameters, there are ways to get decent approximations of them. Search for the testing methods online, and you can find them. If you don't want to do any of this, there is no simple way to make it sound louder. Driver design and manipulation are not easy to do unless you put some time and effort into them.

Answer 5

AWolf said it correctly.  The sub is a matched device of a Driver, crossover, enclosure and power supply. You cannot change one part and have it work with the others.
