Sub PSW12 or PSW303 - what to choose?

[pumba]

Hello Guys!

I'm trying to decide which sub to choose: Polk Audio PSW12 or PSW303?

Same price, same wattage. PSW12 has bigger driver -12'', PSW303 has only 8'' driver, but sales person in the shop keeps telling me that PSW303 is much better.
8'' driver seems kinda suspiciously small to me but I might be wrong

I have Onkyo 503 reciever + Polk Audio Monitor 50 + Polk Audio Monitor 30 + Polk Audio CS1.

Please share your opinion or expirience! Thanks in advance.

Here's a previous thread about others interested in the PSW12:

I don't know anything about the PSW303 so I can't be purely objective; however, I do own the PSW12 and I do like it. It is very musical and it compliments my current audio set up. In the HT world it is very solid and performs very well.
