Three Subwoofers, Multiple crossover settings
Deftech 600, dual 600 sub, Pioneer LX 103, OMW3 Front Height, 5.2.2 The room is 10 feet x 12 feet or so, but it opens up on the left side into a 12x15 area (trapezoid), and on the right there is doorway leading to a small hallway (1902 house). Hardwood, no rug. Drywall over Lath and Plaster. Listening area is 10x12.
Deftech 600 satellites don't go down to 80hz, maybe 120-150hz; Bass 80hz-150hz is directional. To correct this, I have the Front LR speakers set to FULL and they are wired through the LR subs which keeps the mid bass directional (Subs are positioned Front LR). The DT 600 subs are wired for LFE as well. It's works good. I tried some SM45's in my living room and I did not like the weaker treble; I like the sound and look of the 600 satellites.
The DT600 subs don't reach low enough; they fall apart in some movies and start "farting" and walking around the room. I want to add another sub that reaches down to 20hz; I've got my eye on an SVS SB 2000. But, I don't want the SVS to go over 80 hz, and I want to set my crossover at 120hz on the receiver. Is this possible?
And as a bonus is there some way I could limit the DT 600 subs from going any lower than 40hz or 30hz?
Receiver Crossover - 120hz
Front DT 600 LR Subs - 120-40hz
SB2000 - 80hz-20hz
