But when you put a ported subwoofer in a small room, the low-end response increases because of room gain, leading to a bottom-heavy, unbalanced sound. If you look at the subwoofer's quasi-anechoic response, it might be down 18 dB at 8 Hz relative to the nominal level, but in a small room, it can actually be flat to 8 Hz! If you’ve chosen a sealed cabinet subwoofer for your home audio system because it’s tighter and more accurate or because it fits better in your space, there’s a surprising benefit in store. High-Res Music Streaming and the Future of HiFi Audio: You Can Have It All. butie120. It turns out that room gain begins at the frequency whose wavelength is twice the longest dimension of the room.

The app for the SB-3000 has polarity, parametric eq, room gain compensation, port tuning(I know this doesnt pertain to my sub). Retailers, SVS SoundPath RCA Audio Interconnect Cable. SVS designs its sealed subwoofers to roll off below 32-35 Hz or so with a slope of 7 to 9 dB/octave specifically to take advantage of room gain. If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly. Interestingly, the location of the subwoofer has little effect on room gain, though many people report that “corner loading” a subwoofer by placing it diagonally in a corner, facing out, has the best results. Small center, surround, bookshelf: 100-120 Hz. The powerful DSP shapes behavior of the subwoofer to produce acoustically tuned room gain. The numbers below highlight general guidelines for speaker/subwoofer crossover frequencies. There is a dark side to room gain, however. Dan Simon says ... off if it’s that bad (and some are, for sure). Worst case, if you have the sub amp gain set way too high or way too low and the same with the sub output of the Denon then you could get some clipping in the signal chain. For example, if a room's longest dimension is 16 feet, room gain starts at 35 Hz (wavelength = 32 feet); if a room's longest dimension is 12 feet, room gain starts at 47 Hz (wavelength = 24 feet). So remember, when setting up an SVS SB-1000, SB-2000 Pro, SB-3000, SB-4000 or SB16-Ultra subwoofer, your room has a gift for you—free bass that's flat to well below the subwoofer's natural frequency response.

The Magic of 2-Channel Stereo Speaker Systems The subwoofer’s gain was set to maximum, phase was set to 0, and the low-pass filters were left off. All the benefits of greater output and deeper bass extension with pinpoint accurate frequency response. With a sealed subwoofer (as opposed to ported), the room itself has the potential to boost bass below a certain frequency. Let's say the room's longest dimension is 16 feet, so room gain begins at 35 Hz; one octave below that (17 Hz) will be 7 to 9 dB louder than the subwoofer produces by itself, and two octaves below the starting frequency (9 Hz) will be 14 to 18 dB louder than the subwoofer can manage on its own. I know they play loud, as movies show that, but when playing music not at all. AVS Forum Special Member . | pretty simple when using LFE.

This roll-off does not occur in ported subwoofers; they remain fairly flat to 20 Hz or even lower in a quasi-anechoic environment. An improperly tuned subwoofer can turn all that extra output into a boomy, inaccurate mess that only serves to emphasize individual nots and muddy up your listening experience. SVS’s claimed response windows do pan out in our measurements.
