Currently running a pair of Picowreckers in the basement from a 3000dsp, hpf in place with no eq. Floor is concrete and seating is on a wooden riser with Clark transducers. The wreckers are decent, but with 7 channels of redirected bass, destructive room effects, and a healthy house curve, amps reach clipping 3-6db below the level I would like for some concerts and movies(I like loud, but nowhere near rock concert loud). Both have been moved and measured at dozens of different locations around the room with results ranging from disappointing to terrible. The upper response doesn't lend itself well to midbass or easy integration either, so building more of them is not preferable.
I have two rooms in the house large enough to put the system in; acoustically, both are the stuff of nightmares. Planning on four subs and four independent delays to help deal with some of the modal issues. There always seems to be some amount of destructive interaction between multiple subs, but the overall response does end up slightly better and more consistent across a small-ish listening area. Doesn't do a thing for 80-300Hz, but I'll take what I can get. As for frequency extension, the house makes so many distracting noises at low frequency, I'm not convinced I even care about anything below 30Hz. Rumbling sound effects are ok, but gunshots, drums, synth bass, and bass guitar get me far more excited. As much as I would like to move just to have a better environment for my theater, it's not going to happen for several more years.
Would like to avoid multi-way subwoofer setups and the additional integration nightmare they present; just four matching subs with good inductance control in reasonable sized enclosures.
The cost ceiling is based on the most expensive setup currently being considered, which is four 18TBW100-4 drivers each in 7ft^[email protected]
, a pair of NX6000D, 6 sheets of ply, and misc supplies. This is also the largest and heaviest setup I would consider. Don't want to have to haul a dozen enormous cabinets when I move(Did I mention the tiny 90degree landing at the bottom of the stairway?).
The other setup under strong consideration is four UM18s in 4ft^3 sealed powered by two NX6000Ds.
I don't want to have to spend on subwoofer upgrades again. Curious what others would do with a $2500 subwoofage budget including amplification and cabinets.
