upgrading Polk woofer to Def tech woofer?
I have the CS1 center channel how easy or hard would it be to swap woofers like aren't 5.25" speaker mounting holes all standard like both Polk and Def Tech holes would line up on the CS1 cabinet correct?

was planning on leaving the tweeter and crossover as Polk.
the polk cabinet has a tube port vent. the DT cabinet is designed w/ a passive radiating type inclosed type port curious if this has an effect on the woofer?

is this a good plan to add a little umff to the speaker?
Thanks STB

No, you can not do that. No offense but this question that you asked shows you severe lack of understanding about how this stuff works. You can't just unscrew your Polk woofer and put a new woofer on and expect to improve the sound quality. Every speaker has a crossover that is designed for that particular enclosure and combination of drivers. If you change out one of the drivers then you also have to change the crossover, which is very very complicated. If you want better sound quality, then sell your current setup and buy a different one. (note- I am absolutely hate Polk speakers as I feel like they are overpriced junk).

That's the least of the potential issues. Foremost is that the replacement driver must have T/S specs compatible with the cabinet design, then it must have sensitivity and frequency response that will work with the tweeter.
