I was leaning more towards a cheaper sub and getting twice as many. My initial budget might be $1500 if I'm lucky, but I'll plan to add a couple or more each year over time until I'm happy.
The idea of doing a riser horn under the second row I'm not sure about.
Ideally I'd only need about 4 subs 18" sealed to get me flat to 15hz and the level I would listen at (reference or less).
But I'd want something excessive to show off or just experience and smile from time to time, and for music and parties. There's a full bar in my plan and it's going to be an entertainment space. I don't need flat to 15hz though. Flat to that low (or lower) at say 135db isn't needed, but I'd like to hit 30hz to 80hz that loud for music.
Perhaps I'll do a few horns but turn them off for reference quality movie watching - and just tune the room and system without them for great movie audio. If I want to get silly I can just turn them on.
Would that make any sense? Or am I crazy ?
My room is going to have less cabin gain for being so large.
