Tom (Ex-Lab) - PSA seems to have issues, but not sure what they are. Had they allowed me to purchase a subwoofer, here is what would have happened:

It would have been calibrated into the system, and real world listening tests along with accurate in room measurements taken. As PSA uses Eminence drivers - drivers which are very close to what we used at Chase Home Theater - it is highly likely they would have gotten a very good review, as it is equally likely PSA makes an excellent product.
