Suggest reading Floyd Toole's "Sound Reproduction" 3rd edition is the consummate audiophile guide to how loudspeaker and subwoofers behave in-room. Toole worked for decades at the National (Canadian) Research Council then retired from Harmon International (makers of JBL, Revel, Crown, Mark Levinson, etc.) so is perhaps the world's most respected acoustician. He invented Spinorama anechoic chamber measurement, the recognized standard method for loudspeaker testing. He also led decades of trained panels of listeners in comparative double blind testing that validated his testing. His preferred bass reinforcement scheme is the use of multiple subs to reduce in-room peaks/dips.Most audiophiles make the mistake of using full range loudspeakers or lining up one or two subs side-by-side with their main loudspeakers. If you draw 4 inches of water in a bathtub and move your hand in the water lengthwise in the tub waves will be created. The waves travel, like a bass wave, until they hit the end of the tub where they bounce back and collide with the next wave where they will either double up (peak), cancel (dip), or otherwise interfere with each other. Lining up all the subwoofers/loudspeakers side-by-side just makes this phoneme worse. The best solution is to use multiple subwoofers carefully located around the room.Toole found that corner placement or mid-way along each wall produces the best results. Duke LeJeune's swarm is such a system (audiokinesis.com). It is designed to complement room gain and has been well accepted. Realize that sound travels in waves up to the transition (also known as the Schroeder) frequency, roughly 300 Hz (room dependent) and as rays above that. After using multiple subwoofers the next best step is the use of bass absorbing materials, one of the most effective being Owens Corning 703 high density fiberglass that can be found in GIK (see their circle here at Audio Circle). Their 244 "Range Limiter" panels are highly effective. The last step is the use of room equalization, such as REW (Room Equalization Wizard - free, very flexible, but harder to use) or Dirac. Note that this last step should only be used as "icing on the cake" and not substitute for physical solutions (subwoofers, bass absorption).
Love my SVS SB3000. The remote app makes it so easy to setup. Sounds fantastic as well.Oh wait, I'm not a Gasser.
