Hi Darren
First off I would not go near the PB1/Fact8 because they are little speakers for BIG money.The facts are around 88lbs /pair and the PB1's are just a OB1 on steroids for big dollars..All good speakers have some girth and weight.You said you wanted to upgrade and you like some VOLUME.If you can get the OB1's for $2800-$3200 then thats not bad for these.BUT if they are asking $4000-$5000 or more,I would run away screaming.We put the PB1/Fact8 to a test at a local dealers and left laughing knowing what you get for the rediculous money they were asking.
Now the IB1's are a proven ""CHAMP"".These will work in a small room just fine....They will handle a 14/7bsst at ""FULL"" volumes(the OB1/PB1/FB1's little 6.5" woofer will die in due time) and with a good pair of Sound Anchor stands,weigh in at around 120lbs(stands and speaker)Hell,one IB1 weighs almost as much as a pair of Fact8's!!!!


YOU SAID YOU WANTED TO UPGRADE...WELL these are a upgrade.They will stand the test of time and will handle whatever you throw at them.Their soundstage is unmatched and the woofer is a real low bass transducer.


I have tried several PMC's and use my real world experience only during my opinion and mean no offence to anybody who owns any of the speakers here.
