By PSW Staff • May 29, 2009 The new Danley TH-812 "Rock Monster" subwoofer, incorporating eight 12-inch drivers Danley Sound Labs will be introducing three new subwoofers at the upcoming InfoComm show in Orlando, Florida, including the TH-812 (also known as the “Rock Monster”), a tapped-horn subwoofer system that has eight 12-inch long-excursion low-frequency drivers. The Rock Monster delivers exceptional sensitivity, low-frequency extension with very high output into the mid 20 Hz range, as well as very high power handling capability. The new TH-221 (also called “Cine-Monster”) is a tapped-horn sub with twin 21-inch excursion transducers for exceptional low bass for commercial cinemas and high-end home theaters, delivering concert level output to 20 Hz. Other applications include touring, event staging and club systems. Rounding out the group is the lightweight, portable TH-212 subwoofer with two 12-inch waterproof drivers. This model can be ordered with handles and wheels for touring applications, or with a variety of fly points for permanent installations. At only 15 inches high, the TH-212 can easily fit under a stage. A pair of these subs makes for a compact 30-inch tall, high-powered directional bass array. All Danley loudspeakers come in a weatherized finish as standard. Powered versions are also available. Danely Sound Labs will be exhibiting at booth 6741 and demo room W204C at the 2009 InfoComm show.

Four of the subwoofers were positioned in front of the audience under (or behind) the film screen and two more were placed together at the rear of the audience on a platform. Powerful noise energy in the range of 17 Hz to 120 Hz was generated at the level of 110-120 dB(SPL).I am in search of a backup software.The new low frequency entertainment method helped the film become a box office success. More Sensurround systems were assembled and installed. By 1976 there were almost 300 Sensurround systems leapfrogging through select theaters. Other films to use the effect include the WW II naval battle epic Midway in 1976 and Rollercoaster in 1977. With the advent of the compact cassette and consumer digital audio formats, the reproduction of deep, loud bass was no longer limited by the ability of a phonograph record stylus to track a groove.I think high speed internet service is compulsory for every body.It became possible to add more low frequency content to recordings.Home subwoofers grew in popularity, as they were easy to add to existing multimedia speaker setups and they were easy to position or hide.
