Hello everyone, I am attempting to build my first sub and am not sure which direction to start. I have a open concept home and the viewing area is in the living room which is open to the rest of the house. I think my budget doesn't allow for a sealed system so I am thinking either ported or tapped horn will be best. I don't mind if its multiple subs as long as they fit in the space I have designated for them and come in at the $1500 max budget for everything (amp, eq, drivers, wood). The space is 50"W X 50"D x 60"H. I am not scared about the construction aspect of this build, it's the eq I need to do that has me a little nervous so maybe a design that isn't terribly difficult to integrate into the room. listening habits are generally between -10 to -20 on the receiver and it will be used for movies/television with a little music and gaming thrown in. Expectations for the new sub would be something that digs DEEP. My old mirage s12 was useless below 23hz so I would like to get down to the mid teens that is nice and tight with decent spl. So what would you guys do in this situation? Thanks for taking the time to read this post!
