Kent Moore, sound engineer with DTS, Inc., is clearly pleased with the subwoofers installed in the Mastering Room studio at his facility. “These Bag End subs give me a clear and solid presence of the extreme low end without overpowering the mix, as I have found other bass solutions do. And yet they can hit hard, too, if you ask them to. For 7.1 movie demos, we make sure the +10dB to the LFE is on, which ensures the explosions will be both felt and heard. Customers become pleasantly impressed during demos when their pants shake against their legs and the audio remains crystal clear.” DTS, Inc. is a digital technology company that has been dedicated to delivering the ultimate entertainment experience since its founding in 1993. DTS decoders are in virtually every major brand of 5.1-channel surround processor, and there are hundreds of millions of DTS-licensed consumer electronics products throughout the world. A pioneer in multi-channel audio, DTS technology is in home theatre, car audio, PC and game console products, as well as DVD-Video, HD DVD, Blu-ray Disc and Surround Music software. Headquartered in Agoura Hills, California, DTS now has offices in the United Kingdom, Canada, Hong Kong, Japan and China. The “Mastering Room” name remains from a time when the studio was used for mixing surround sound for 5.1, 6.1 and 7.1 releases. While the room is occasionally used to mix high priority 7.1 releases, today the room is used primarily as a demonstration room for customers, journalists and other audiophiles, as well as a Quality Control studio for internal encoder/decoder critical listening tests. All of these functions require that the quality of the sound be of the highest level, with minimal distortion and maximum fidelity. The Mastering Room is outfitted with two Bag End P-S18E-I subwoofers. The P-S18E-I is a high-output self-powered subwoofer system designed to provide high fidelity extended low frequency audio reproduction from a relatively small enclosure. This system includes the INFRA-MXB-8 integrator which insures a perfectly flat acoustic response down to 8 Hz. The extended low frequency response allows monitoring and quality control in the subsonic region. “With the Bag End bass system,” says Moore, “the listener can quickly tell whether the low end of a mix is too light or too heavy without having to crank up the volume. That is especially important for me, as I tend to mix at a lower mixing level compared to other engineers (generally around 75dBSPL). The Bag End subs provide an even low-end presence across the entire low frequency spectrum and track evenly as you raise the level.” In addition to the Mastering Room, DTS has installed another Bag End subwoofer system in a newly completed research and development studio.
