Longtime internet lurker, admirer of headfi information that's out there on these forums, and first-time poster because none of it, I find, suitably answers my question. Soon my fiancee and I will be employed at a downtown drop-in center for the struggling marginalized. As the director of this drop in and I share a similar interest in music therapy we would like to play music for relaxation for those struggling with many afflictions. The room that we will be playing in is, if I need to overestimate a bit, 30 feet by 32 feet. I am not sure how tall the room is but is lofty. The room is of old/cheap wood on all sides + plaster. I have insufficient information to know the frequency response of my audio source, a lenovo ideapad 310 except that it's "Dolby Audio." We'll be playing all sorts of ambient/downtemp: house, techno, trance, jungle/drum n bass, idm, experimental/leftfield, dub, psy, drone, modern classical, minimal. We'll also be playing all sorts of chill out such as instrumental hip hop, jazz rap, acid jazz, nu/future jazz, trip hop, jazzdance, soul-jazz, latin, synth-pop, R&B, soul, funk. As to persons in attendance, we're not sure the numbers. There are so many people who visit the the drop in on a daily basis. We wish to extend the bass as deep as possible and have audio clarity and balance. We are hoping the bass response can be felt. We do not wish a permanent installation. ... asking the community here to provide offer some excellent suggestions for speakers and sub(s). We also asking suggestions for the very best dac and dac model for the job. As I said, I've been lurking on various forums and so far the best solutions I've found, and I admit I know virtually nothing is a klipsch promedia 2.1 with a schiit dac (though unclear as to which one, we won't be keeping the equipment on all the time..) or krk rokit 8's plus a krk sub 10s. I have no idea whatsoever if these are good options for the dimensions of the room or for what I am expecting for those visiting for music relaxation.
