Filling a 6600 Cu. ft. room


Hi there I am curious to see just how large of speakers and how many sub woofers it would take to fill a 30x40 space

Its a barn and has vaulted ceilings obviously due to a barn.
Im not certain what the spacing up there would be

Im dreaming of one day getting the genesis 300 when im on top of the world. I havent heard them, I just have extreme faith in arnie nudell and havent seen many speakers that really make me wanna upgrade from B&W Matrix 804's. The JM Labs mezzo Utopias interest me as well as the leagcy focus 20/20. I have heard the new Etopia EM with the VTL Seigfrieds and was blown away and its not the greatest reference but i have the focal utopia components and subs from 2000 or so in my car and they do rock just amazing, I even find myself listening to the jazz staion occasionaly because it comes in well and im not a jazz guy. Any way Ive been looking at the Velodyne HGS18, Paradigm Servo 15, I know enough to know i can no longer go with what seems cool and I need to get help from folks that really know whats up.

6600 cu.ft? 30x40 means 1200sq.ft. To get that to 6600cf.ft. means you have a ceiling height between 5 and 6 feet. That cannot be right.

I suspect that a pair of Mezzo Utopias might be suitable, especially if you are planning on adding subs. I have heard the Utopias give a great performance in a similar-sized room (with a 16ft ceiling) and my daughter has a room of that size with a Revel 5.1 system that works pretty well.

You say you are not a jazz fan but you do not say what you do want this system for. What kind of music? Will this be only a 2 channel system?

Basicly I am building a barn, I am going back and forth on putting a listening room in (Expensive) or just putting my stereo on one side of the house and not having to build any walls except for the bathroom, and it would be 6 foot wools and a barn ceiling 1/2 or 2/3 as much space, MY Cu. Ft. was off
I vote for putting the stereo (one question answered) in a portion of the larger space. First, a subdivision would have to be substantial to be isolated but, second, whatever internal walls you build will introduce their influence on the sound. OTOH, if you are going to dedicate a portion of the room to the system and to serious listening, you do not have to "fill" the room.

A lot depends on your listening preferences, which you have not described for us. If you just want to play background music, pick a pair of speakers and place them where you want. They will probably be too loud close to the source and not loud enough farther away.

I agree with Kal (as always), a dedicated space will give you the best option to hear music the best way e.g. optimized for the room. Pick your gear according to the size of the dedicated space.

Third option: why do you need to be limited to one rig? You can place two or more small systems in various parts of the barn space, the setup optimized for the "local" space. This is a no brainer if you will be using an audio streamer like Sonos or the Logitech systems. If you use active speakers you will not need anything other than the streaming devices and the speakers. More gear is a good thing, IMHO. Disclaimer - my wife does not agree.
