upgrading speakers

i've got an old HH 15" bass cab that i've had sitting around for a while - i never really use it as it's only rated at 150W.

i'm thinking of upgrading the speaker to something in the region of 400W.

would there be any issues with bunging a much larger speaker in a box only rated for 150W (speaker parameters and box tuning aside)

It shouldn't be a problem, unless the glue joints have weakened over time.

Don't let that stop you using it, thermal power handling ratings are pretty irrelevant for bass playing. If it does fart out too easily that's an Xmax issue, nothing to do with the 150W rating.

I would check if the cab has any passive internal electronics, such as a crossover or other filtering.

If these are being used to limit what frequencies are being sent to your driver, they may only be rated for 150W and fry before the new driver does.

If the external socket is just a straight cable onto the driver terminals, then all should be fine.

good point, although there's no filtering or x-over in the cab.
