Well, it's kind of embarrassing but the amp I'm using to power the IB is an old Kenwood prologic !? Under powered for the job (120 per channel) but even so, great results.. Smooth bass just rolls out of that puppy.. IB's are to die for when it comes to music, not to mention the earth moving they provide during a good action movie..
As for location, they are very forgiving.. You can mount them behind, above or to the side of the mains with no problem.. It's not recommened, but some have mounted them behind the seating area without complaint..
Yes, I have the BFD, but have not put it on line as yet..
Even without dialing it all in I'm happy..
