I can't argue, the SR5003 isn't a beast but the RF-82's are rated 98db efficient, the room is 15x15 so I had no idea what to expect but the meter did hit 124 in 2009 when I shot the video from the listening position. I won't know until I get a calibrated meter I guess, but this weekend I over-stressed both MFW's and their Version 2 amplifiers went out in a loud screeching mess.
I installed Version 1 amplifiers to get me by until Mark Seaton has his new amplifiers ready this week.
To bring my post closer to topic, during the Bass Mekanik song "Subsonic" that's where I hit 124db back in 2009 and this weekend when it hit 123db. During these peaks the bass makes the floor shutter and my neighbor, whos house is 25ft away, she said her china cabinet was rattling.
I'll post a picture of the room, for a living room it's small.
