Bass can be a problem with certain recordings and I can't really drive these to "dance club" levels with my 100 watt tube amp. However, even without room treatments the sound stage is super wide and deep. I'm planning to treat the walls and corners which I believe will really help tremendously.
Wow, that is a large room you have there. Nice. Very nice setup for the ProAcs. what do you think about the bass from these speakers in that space? Very nice equipment overall. Enjoy your music!
