15' listening distance = 175w Look ma, I need external amps!
18' listening distance = 275w mine's bigger than yours is

To listen at 95db w 15db headroom

8' = 157W WHAT?? YOU LIKE MY EXTERNAL AMPS? ;\)
12' = 344w
15' = 509w
18' = 760w

In my apartment I can listen at reference from my kitchen. In some of the rooms you guys have, my receiver would barely keep up in the main room.




Wow, that is eye opening! I suppose with 11,000 cubic feet to fill (35 x 35 x 9), and my seating position 17 feet from my M80's it's easy to understand why I needed the Emotiva to help out the Axiom towers. I have posted in previous threads that they sounded a bit 'strained' at higher volumes with just the Denon (125 watts per channel) pushing them. With this example, it's easy to understand why now.

Ok ok, so you've made a good example of why room size matters... I STILL wouldn't be caught dead in an Escort!!!
















(just playing, I once owned a 1990 Ford Escort. Wasn't flashy, but it motored along without any fuss. Never had that thing in the shop once and it had over 100,000 miles on it when I let my brother in law buy it off of me... I think he totaled it 2 months later!)
