Room Size: This tool assumes that the subwoofers will be used in an enclosed room. The results will be less accurate in an open concept space. When in doubt, always overestimate room size.

Subwoofer output needs are based on total room volume (cubic feet), not on room area (square feet). Its results will be less accurate in an open concept space. When in doubt, always overestimate room size.		HSU VTF-2 MK5780PortedAudioholics

Target Bass Extension: We recommend targeting 20Hz bass extension to realize the full benefit of home theater audio tracks. Deeper bass is inaudible and difficult to predict. This tool cannot guarantee accurate results below 20Hz. A higher bass roll-off (25-30Hz) can result in lost audio content, but is less likely to bother others in shared spaces and cheaper to implement.HSU VTF-TN11300PortedManufacturer

Number of Subwoofers: It is our recommendation to use two subwoofers whenever possible. One subwoofer is likely to produce inconsistent results. Four subwoofers has the potential to improve consistency and output, but is more difficult/expensive to calibrate properly and has a higher likelihood for user setup errors.Monolith M-2121800PortedManufacturer

Subwoofer Placement: Placing your subwoofers in the corners of the room results in the greatest amount of room gain (+9dB) but can create a more inconsistent frequency response than other positions. Placing a subwoofer against a single wall will result in 6dB of room gain. Having the subwoofer freestanding in the room will result in the least amount of room gain (+3dB)SVS PC-40002200PortedExtrapolated

Reference Level: This tool assumes that full cinema reference level for LFE is 95dB average and 115dB peaks in-room. Home reference level is estimated to be 7dB below that (88dB/108dB).

Sealed vs Ported: Our position is that there is typically no audible sound quality difference between sealed subwoofers and competently designed ported subwoofers. However, some individuals will prefer sealed subwoofers for music playback. It is not advisable to use sealed subwoofers for home theater except in cases of an exceptionally high budget or low output requirements. It takes substantially more money and power to achieve the same results with sealed subwoofers compared to ported.
