I want to smooth out and improve the sound from my sub bass in my oddly shaped basement theater.
I'm currently running 2 Dayton Ultimax 18's each in a parts express flat pack sealed enclosure. I have one Behringer NX3000 and one Crown XLS1500 (planning to replace Behringer at some point with another Crown). Amps are gain matched and I'm running a minidsp. AVR is Denon X6700.
I've tried so many times to get a smooth response at my prime seating location, but the room is really wild with a long hallway and staircase. Theater is in a large area of a finished basement with 8ft ceilings.
No amount of sub placement moves, time alignment can get me a smooth response. I have massive holes no matter what I do. Mains are Klipsch RP280s and I have moved them close to wall, or far away, and nothing works. Huge problems between 50-100hz no matter where I crossover or set filters in REW/MINIDSP.
Question: Should I purchase 1 or 2 additional UM18s (now UM18II's)? I really want that chest kick bass (totally lacking in the room), and have considered 4 marty cubes or mini marty's from GSG and putting their recommended pro drivers in them for that better upper bass (I probably cannot afford all that at once, but I want to put the endgame plan together).
Option 1: 2 more Ultimax sealed box combos w/drivers: $1050 (should I consider getting a different driver? new dayton or pro driver?
or Option 2: 4 minimartys: $1250 (shipped) + 2 Lavoce 18s ($740) for now, replace 2 UM18s later for another ($740): Total eventual investment $2730.
Please help. Will the cheaper option fix the problem and give me that chest slam? Or should change gears and get the large ported boxes with improved drivers? Is it worth it?
