Sub question

ozone · 31st March 2005, 12:44 PM

I have some powered subs but it can only take up to 50 Watts so I was wondering if I pulled the box open could I just switch the speaker inside of it for a better speaker or do I have to rewire the whole thing up

The box is most likely optimised for the driver in there. A better driver would probably have different T/S-parameters and therefor ask for a different enclosure.

If you more than 50 W perhaps you have the wrong speaker for the job.

ozone,

It may be that the amp that is driving the system is only 50 watts, so you would have to renew the amp. If this is the case and you might also need to up the woofer, which means starting again.

Sure you can replace the driver.

Find the cubic volume of air in the cabinet, also the tuning frequency of the port. You will need the surface area and length of the port to figure that out.
Once you have that information, you should be able to find another woofer that will work in the cabinet without any problem.

If it is an amplified sub-woofer, that is a different problem. The amplifier built in would still be the same and this wouldn't help. You would then need to replace everything.
