[QUOTE="Art Welter, post: 26785, member: 52"] Re: Subwoofers with 30hz performance. The BT7 horn cutoff with 8 cabinets is above 25 Hz. Although it has less than 1% distortion at 25 Hz, it is not designed for high output that low. Under 10% distortion is pretty hard to hear below 100 Hz or so, as long as a (good) conventional speaker is kept below Xmax it should be below 10% distortion. The Bag end infra systems go very low, but being a conventional speaker driven below Fs in a sealed box have little output down low. The processor limits output to keep the speaker within Xmax, therefore keeping distortion in check. As their hype, er spec sheet says: “While the INFRASUB-18 will reproduce 8 Hz, it is not audible nor does it have enough acoustical power for you to feel it. The measurements are taken at close range with sensitive instruments. To achieve a flat response, as shown in figure 1, full amplifier power is used at the lowest frequencies and very little (<1 Watt) in the upper frequency range.” Good for home theater and low volume work, but not for heavy lifting.
